As for land preparation (or land leveling work), HHTP-MB will at least responsible for Research and Development Zone, and land preparation for other zones will be carried out by HHTP-DC in principle. However, some land preparation work other than Research and Development Zone could be carried out by HHTP-MB in parallel with construction of common infrastructures in order to ensure to maintain the implementation schedule.

In this Pre-feasibility study, all the land preparation work is assumed to be carried out by HHTP-MB, thus included in the scope of study. While, other development work which will be carried out by HHTP-DC is not covered by this study.

2. LAND PREPARATION AND DRAINAGE SYSTEM

2.1 Outline of Original Sector Plan

(1) Land Preparation

Land grading elevations were determined so as to minimize land preparation cost and avoid flooding from the Tich River in the original JICA Master Plan (M/P) and Feasibility Study (F/S). Land for the R&D and Industrial Zones was planned to be safe from a 100 year probable flood and the arterial road was planned to be safe from a 10 year probable flood. Design elevations were set to be at least 10.0 m above MSL (mean sea level) for the R&D and Industrial Zones and 8.5 m for the arterial roads.

The ground elevation of parts of the industrial park in the southeast of the HHTP and New town in the northwest are lower than 10.0 m. Land grading volume was estimated at around one (1) million m3 for filling of those areas.

(2) Drainage Plan

According to the original JICA M/P and F/S, the drainage system covers an area of 920 ha, which is divided into six drainage zones according to the land uses. Each zone was to be provided with a drainage network made of concrete U-channel and Hume concrete pipe (HCP) along the road in Phase-1. The main features of the drainage facilities are summarized below:

2.2 Present Condition

2.2.1 Current Development Progress

After the JICA M/P and F/S, the development plan was reviewed for the Construction of the Road and its facilities under Stage-1 of Phase-1 by HHTP-MB. A total of 200 ha of the whole of the HHTP area is being developed gradually by VINACONEX. Although some companies have already moved into the HHTP and started operations, the land preparation work is still on going and is scheduled to be completed by 2008.


2-2

A total of 31.5 ha of the land for stage-1 has already been prepared, and the existing grading level was constructed as set out in the road development plan.

However, the drainage system is not in faithful accordance with the JICA M/P. Existing main drainage facilities are summarized below.

2.2.2 Related Projects

As noted in the above section, the drainage plan was reviewed by HHTP-MB and partially constructed for the area of 200 ha as Stage-1 of Phase-1. There is no other related land preparation or drainage projects in the HHTP area.

2.3 Update of Sector Plan

2.3.1 Sector Development Missions, Strategies and Goals

Although land preparation has been partially advanced by VINACONEX, the land preparation plan should be updated based on the road and land use development plan of this study.


2-3

As noted in the above section and the road development plan of Chapter 8, the following three reasons show that the revision of land preparation and drainage plan are necessary; 1) Proposed road alignment and land use have been revised from the JICA M/P in this study, 2) Drainage facilities have been partially installed by the HHTP-MB without reference to the JICA M/P, 3) Catchment basins of each drainage facility will be modified based on the proposed road and land use development plan in this study.

Mission, strategy and goals for land preparation and the drainage plan are set forth as stated below:

Table 2.3-1 Missions, Strategies and Goals

Land Preparation Drainage Plan Mission To develop land where industry

and housing can be developed To enhance investment activities without any interruption throughout the year To complete a systematic drainage network covering the entire HHTP area

Strategies To be able to access the developed area smoothly without any difficulty To prepare the land in conjunction with the drainage plan To be consider the existing elevations of the roads

To minimize inundation areas by constructing proper drainage facilities To install a drainage network in conjunction with the road development plan To reinforce the O&M system of HHTP

Goals To prepare the land by filling and cutting by 2020

To install drainage facilities in the developed area by 2020

2.3.2 Planning Framework

(1) General criteria for Land Preparation

The elevations of the existing roads which were constructed in stage-1 shall be kept as they are. The grading elevations for the area that will be developed in Phase-1 are to be decided in consideration of the road and drainage development plan. As noted in section 1.1, minimum grading elevation shall be higher than 10.0 m above MSL to minimize the flood risk.

(2) General criteria for the drainage plan

According to the original JICA M/P and F/S, water levels of Tich River are estimated at +8.0 m, +8.5 m, +9.5 m and 10.0 m for the return period of 5 years, 10 years, 50 years and 100 years respectively. Serious inundation by the overflow from the Tich River is rare since the average ground level of HHTP is higher than 10.0m.

In this study, the entire HHTP area is divided into 5 basins, the Tan Xa Lake basin, Central Canal basin, South Canal basin, and R1 and R2 basins as shown in Figure 2.3-1. Storm water which is collected by drainage facilities in each basin in the HHTP area is discharged into Tich River in the east side of HHTP.

The natural lake and wetlands that in the present high-tech park play the role of storage facilities during heavy rain. However, the lake and wetlands will disappear and discharge volume will be increased after the land preparation is completed. Therefore, it is necessary to construct suitable drainage facilities in accordance with the updated land use, land preparation and road development plan. Moreover, it is necessary for Tan Xa Lake and Canal to have sufficient cross-sectional area to carry the flow to the Tich River.


2-5

2.3.3 Sector Development Plan

(1) Land Preparation

The land preparation plan is formulated on the basis of the road and the drainage development plans. The land grading volume is estimated on the assumption that the land grading elevations are the same as the planned road elevations. Volume of filling and cutting are calculated by the difference between existing ground levels and planned road elevations. Calculation results show that total filling volume is around 24 million m3 and cutting is around 11 million m3 of which around 9.3 million m3 of filling which represents 40 percent of total filling volume will be required in Phase-1 and 14.8 million m3 of filling which represents 60 percent of total filling volume will be required in Phase-2.

The drainage plan basically follows the existing drainage system. However, it is necessary to modify it to be in conformity with the proposed development plan. Especially, it is necessary to take into account the proposed road alignment which was modified from the original JICA M/P and FS. Existing drainage facilities including those under construction on the road project have less capacity than required. An updated drainage plan in accordance with the proposed road development plan is required in the study. The drainage plan shall be formulated to keep as much of the existing drainage facilities intact as possible.

2.3.4 Development Issues

There is no retention pond planned in the catchment area of the drainage plan in order to keep the area where companies can be located as large as possible. However, the Amusement zone has some ponds which are naturally generated in the lower area. It is suggested that those ponds shall be kept as is when the area will be developed to minimize the flood risk downstream.

And also, to decrease peak flow during the heavy rain, a retention pond will be needed downstream. Further investigation in the future is needed for planning of the location and the volume of the retention pond. Especially, review of the discharge volume at the point of discharge to Tich River shall be necessary.


2-6

2.4 Proposed Project List

Based on the area for each development phase of the land use and road development plan, land preparation will be developed in Phase-1 and Phase-2.

The drainage project shall the follow the road project which is also divided into two phases since the U-channel will be installed under the sidewalks of the road as shown in Figure 2.4-1. The drainage system of each phase is as shown in Figure 2.4-2.

Main features of the land preparation and drainage are listed in Table 2.4-1.

2.5 Technical Study for Phase-1 Development

2.5.1 Land Preparation Plan

The area to be developed is based on the phasing of the land use development plan. As described in Table 2.4-1, total filling volume is estimated at 9.3 million m3, of which, 4.9 million m3 of filling material shall be obtained from somewhere outside of HHTP.

2.5.2 Drainage Plan

(1) Drainage Zones

In principle, the whole HHTP area is divided into five zones by topographical aspects as shown in Figure 2.3-1. Storm water which is collected in each zone shall be discharged into Tan Xa Lake, the Central Canal, South Canal, and Tich River respectively.

According to the brief site investigation of the study area, it is difficult to find the boundary of the water surface especially for the undeveloped area. However, at least, it is necessary for the discharge points at Tan Xa Lake, Central Canal, South Canal and Tich River to be maintained in order for the storm water to be discharged out of the HHTP project boundary after the land preparation is completed.

(2) Planning and Design Criteria

The following criteria are applicable for the planning and design of the drainage facilities. Hydraulic calculation results are shown in Table 2.5-1.

1) Rainfall Intensity

I=0.36 x 5426 x (1 + 0.25 x logP x t0.13) x 1/(t+19)0.82

3. ROAD AND TRANSPORTATION SYSTEM

3.1 Outline of Original Sector Plan

In the original road sector plan, seven types of internal road were planned to cope with different requirement by various kind of land use in the HHTP such as Research and Development Zone, Residential Zone, Urban/Business Zone, etc. Road length of the internal road, which were included in the HHTP project, and the external roads, which were not included in the HHTP project, would amount to 19.8 kilometers and 13.7 kilometers, respectively, as shown in Table 3.1-1.

In the original sector plan, the traffic demand in the HHTP was estimated at 27,000 PCU per day in 2020, and a main road with four lanes was considered as necessary to cope with the traffic demand. However, considering enough room in the planning of the HHTP, the main road was designed to have six lanes in 2020.

As for passenger transport, the development plan of a railway for electric train service between Hanoi and the HHTP was still in the master plan stage and immature, two stations were planned in the Urban/Business Zone and in the vicinity of the High-Tech Industrial Zone assuming the train passenger demand of 3,000 persons per day.

3.2 Present Condition

3.2.1 Current Development Progress

Current road development in the HHTP has been in line with land acquisition. Development status of road is shown in Figure 3.2-1. Development of roads has been delayed due to the slow progress in land acquisition. However, among the total roads of 8.7 kilometers that are to be developed under Stage 1 of Phase- 1, 6.2 kilometers have been complete or near complete. The remaining 2.5 kilometers of roads are in process of construction.

3.2.2 Related Project

There are two ongoing key road projects that are related to the HHTP: Lang-Hoa Lac Highway and Hanoi Ring Road 3 South.

(1) Lang-Hoa Lac Highway

The project to expand the existing two-lane Lang-Hoa Lac Highway (12 meters in width), which links Hanoi and Hoa Lac, to six lanes is one of the most important road projects for development of not only the HHTP but also new satellite urban areas of Hoa Lac, Xuan Mai, and Mieu Mon. The highway is 30.169 kilometers in length from Trung Kinh bridge in Hanoi to Hoa Lac center. In the expansion and completion project for the Lang-Hoa Lac Highway, the highway will be expanded from current 12 meters to 140 meters in width, consisting of a three-lane expressway road and a two-lane frontage road in each direction.

With investment capital of VND 5,379 billion (336 million US dollars), the project is expected to be finished by the end of 2009. The Vietnam Construction and Import-Export Corporation (VINACONEX) is the investor and contractor of this project. The Lang-Hoa Lac Highway will be turned into the most modern highway in Vietnam.

(2) Hanoi Ring Road 3 South (section between Lang-Hoa Lac Highway and National Highway 5)

In the master plan proposed in HAIDEP1, the Hanoi Metropolitan Area should have eight radial roads.2 Moreover, the HAIDEP master plan includes four ring roads, none of which have been completed yet. Some of these roads can be considered as the key to the successful development of the HHTP in terms of road transportation, and therefore listed as external infrastructure for the HTTP.

By completing missing southern part of Hanoi Rind Road 3 (RR3), Lang-Hoa Lac Highway will be linked with National Highways (NH) 6, 1 (1A and 1B), and 5. Though this project is located in Hanoi, it serves as a bypass for passenger and freight traffic to and from Lang-Hoa Lac Highway. Thus, it is urgently necessary to improve this imporant access from the HHTP to the main ports in northern Vietnam such as Hai Phong and Cai Lan as well as to the main artery, NH1.

RR3 is planned as a primary six-lane road with a typical cross section of 36 meters in width. The project of RR3 South is divided into two sections: southeast section (between NH1 and NH6) and southwest section (between NH1 and Lang-Hoa Lac Highway). The southeast section3, which is about 13.5 kilometers in length, connects

three main radial roads, that is, NH1A, NH1B, and NH5 through three bridges and approach roads. At present only the Thanh Tri Bridge, which crosses the Hong River, is complete and in use. Total project cost for this section is some 490 million US dollars, about 70 percent of which will be provided by the Yen loan. This section is to be completed in 2011.

Meanwhile, the southwest section4, which is about 6.1 kilometers in length, connects three main radial roads, that is, NH1A, NH6, and Lang-Hoa Lac Highway. Total project cost for this section is some 356 million US dollars. At present Phase-1 of the project is complete.

3.3 Update of Sector Plan

3.3.1 Sector Development Missions, Strategies and Goals

It is necessary to develop the various infrastructures to realize the urban plans, accumulate population, and attract high-tech industries to the HHTP. Roads are particularly the most basic development infrastructures. Roads have two types of important functions, namely, transportation functions and spatial functions. First, roads should serve as the main means of transportation, supporting various kinds of activities in the HHTP. As such, the following strategies need to be considered.

• Roads should be planned as an optimum both for private road users including bicycles, motorcycles, and cars and for public transport users including bus and future UMRT passengers. It is important to design roads and lanes leaving enough space and flexibility for adjustment and redevelopment that might be necessary in the later stage.

• It is also important to make safe, comfortable road and transportation plans for all users including residents, visitors, workers, students, and heavy vehicles. In line with their major means of transport and their major destinations in the HHTP, proper separation of those different types of traffic flow should be considered.

• Apart from the original master plan, roads in the HHTP should be treated as either internal or zonal infrastructure rather than external infrastructure. Moreover, some roads that are located outside the HHTP gates are directly related to the HHTP, and thus they should be planned as “internal infrastructure” for comprehensive development.

• It is not until proper linkage to external transportation infrastructure is provided that the HHTP will become fully attractive for prospective investors. Therefore, connectivity with external transportation infrastructure, especially, adjacent Lang-Hoa Lac Highway, should be reinforced not only for road planning but also for transportation planning.

4 The project of the southwest section of RR3 is referred to as TR-07 in HAIDEP.


3-5

Second, roads should provide space for other infrastructures including water, sewerage, drainage, electricity, and communications, supporting various kinds of activities in the HHTP. As such, the following strategies need to be considered.

• Roads should provide enough underground space for utilities leaving flexibility for future development and maintenance. Width of cross sections should be based on the maximum size of utilities, and thus the number of different cross section types should be simplified.

• Some important zonal roads should be planned and developed as part of the master plan in order to make reasonable, comprehensive utility infrastructure network plans. On the other hand, smaller zonal roads may be constructed in each zone by actual developers to serve local areas, but those are not included in the master plan.

To summarize, missions, strategies, and goals for road and transportation sector are set forth as below.

Table 3.3-1 Missions, Strategies and Goals for Road and Transportation Sector

Missions To provide transportation functions to support various kinds of activities in the HHTP

To provide spatial functions for other infrastructures including water, sewerage, drainage, electricity, and communications

Strategies To design roads and lanes leaving enough space and flexibility for later adjustment and redevelopment To separate traffic flow of different types of users for safer, more comfortable transportation To include some roads located outside the HHTP gates for comprehensive road development To reinforce connectivity with external transportation infrastructure, especially, Lang-Hoa Lac Highway

To provide enough space under the roads for utilities leaving flexibility for future development and maintenance To develop some important zonal roads along with the internal roads for reasonable, comprehensive utility infrastructure networks

Goals To complete the development of road and transportation as the most basic infrastructure of the HHTP by 2012 (for Phase-1) and by 2020 (for Phase-2)

Furthermore, it is important that roads should comply with the present conditions of the HHTP, from an economic and environmental point of view. As such, the following strategies need to be considered.

• For update of the master plan network, it is necessary to make the best use of the roads that have already been constructed or are currently under construction under Stage-1 of Phase-1.

• For road planning, it is necessary to leave some critical points unchanged including infrastructure and buildings that have already been constructed, canals, rivers, and lakes. Landscape design should also be taken into consideration.

3.3.2 Planning Framework

For planning purpose, transportation can be classified into external and internal transportation infrastructures. For the HHTP, it is important to be linked with the external transportation infrastructure, while internal transportation planning should be properly designed taking into the future travel demand into consideration.

(1) Linkage with External Transportation Infrastructure 1) Lang-Hoa Lac Highway

In the expansion and completion project for the Lang-Hoa Lac Highway, the highway will be expanded from current 12 meters to 140 meters in width, consisting of a three-lane expressway road and a two-lane frontage road in each direction. Furthermore, 20-meter technical corridors have been reserved between the roads for future development of a UMRT (urban mass rapid transit) system. A typical cross section of the expanded Lang-Hoa Lac Highway is exhibited in Figure 3.3-1. Trees will be planted along both sides of the highway. There are a total of 10 interchanges5 planned on the way, and a toll plaza is to be constructed around the 21-kilometer post from Hanoi. Although the nearest interchange to the HHTP was planned just in front of the main gate (i.e. KM28+971), the current interchange plan has been canceled so far.

Source: VINACONEX

Figure 3.3-1 Typical Cross Section of Lang-Hoa Lac Highway

Since the expansion project of Lang-Hoa Lac Highway will be the most crucial for external transportation to/from the HHTP, it should be completed without any delay. Moreover, for closer linkage with the HHTP, an interchange, which directly connects the eastern sub-gate and Lang-Hoa Lac Highway, should be added (i.e., KM27+000). Furthermore, access from the main gate to Lang-Hoa Lac Highway should also be considered.

2) Urban Mass Rapid Transit Line 3 (Hoa Lac-Ba Dinh route)

In HAIDEP, an urban mass rapid transit (UMRT) is defined as a public transportation system with a large passenger capacity at more than 5,000 passengers per direction per day. It is operated at high speed and segregated from other traffic. It may include various types of rail-based system such as commuter rail, light rail transit (LRT), and subway as well as bus rapid transit (BRT) which

5 Some “interchanges” are simple grade separation connecting crossing roads with the frontage roads of Lang-Hoa Lac Highway.


3-7

can be selected depending on the demand. For example, a UMRT line can be initiated with a BRT and eventually converting it to urban rail as demand increases. The BRT must be planned in a way that its structure and land can be smoothly converted to urban rail. Alternatively, a UMRT line could be comprised of a rail-based system (where the demand is high) and a BRT (where the demand is moderate) with an intermodal facility at the connecting point.

The UMRT lines originally proposed by the Ministry of Transport (MOT) were consolidated into four UMRT lines on the basis of the future urban structure and demand in HAIDEP. UMRT Line 3 consists of two major components, Nhon-Hoang Mai route and Hoa Lac-Ba Dinh route. The former route connects the western suburb of Nhon and southeastern suburb of Hoang Mai via Hai Ba Trung, while the latter route connects Hoa Lac and Ba Dinh (transfer station with UMRT Line 2) on the southern banks of the West Lake. The latter Hoa Lac-Ba Dinh route, shown in Figure 3.3-2, runs parallel to Lang-Hoa Lac Highway and has a major interchange with the Nhon-Hoang Mai route near Daewoo Hotel on Kim Ma.

Figure 3.3-2 Proposed UMRT Network

Hoa Lac-Ba Dinh route of UMRT Line 3 is considered as an effective means of passenger transport connecting the HHTP and Hanoi. It is expected to promote urban development on the Lang-Hoa Lac Highway. The 20-meter technical corridors that have been reserved on Lang-Hoa Lac Highway may facilitate construction of this UMRT line. For this route, phased implementation plan with a combination of different modes of transport may be effective to satisfy current and future passenger demand. For example, this route could be initially served by a road-based BRT system and a connecting feeder bus network, especially on the Lang-Hoa Lac Highway section, and then the BRT could be gradually upgraded to a high-capacity rail-based system. For the best connectivity with the HHTP, a branch line of this UMRT route and as well as several stations should be planned in the HHTP.

(2) Travel Demand Projection within HHTP

Travel demand has been projected for the gateway trunk roads which will connect two interchanges and three HHTP gates. Projection of the traffic volume is based on the

Hoa Lac-Ba Dinh Route

Nhon-Hoang Mai Route


3-9

planned population of the HHTP. In addition, future characteristics of travel in the Hanoi Metropolitan Area projected in HAIDEP including trip rates, mode shares, and occupancy rates are taken into consideration, as shown in Table 3.3-2. Excluding public transport, future daily traffic volume on the gateway trunk roads is estimated at around 27,000 PCU per day for 2012 and around 67,000 PCU per day for 2020. Road planning should be based on these figures.

As for public transport, which consists of UMRT and conventional bus, total passengers are estimated at around 12,000 persons for 2012 and 59,000 persons for 2020, though the actual mode shares are highly dependent on the locations of the workers and students who live outside the HHTP.

3.3.3 Sector Development Plan

(1) Internal Road Infrastructure

The following criteria have been used to define the internal road infrastructure of the HHTP:


3-10

• Main roads in the HHTP that traverse and connect different zones of land use (except for residential zones);

• Roads in the HHTP that are expected to serve major traffic to and from outside the HHTP; or

• Roads that are outside the HHTP boundary but are dedicated mainly to the traffic to and from the HHTP.

Internal road infrastructure is presented in Figure 3.3-3 along with the zonal roads. Total length of the planned internal roads sums up to approximately 21.7 kilometers. Two roundabouts are also planned in the HHTP as part of internal road infrastructure. Moreover, it should be noted that an interchange/grade separation which directly connects the frontage roads of Lang-Hoa Lac Highway and the gates to the HHTP could also be included as internal road infrastructure because most trips between Hanoi and the HHTP are planned to be made through the interchange/grade separation dedicated for the HHTP.6 There are two possible locations: one (KM28+971) in front of the HHTP main gate, and the other (KM27+000) connecting with the eastern sub-gate of the HHTP. The former is a simple grade separation providing a ramp from the HHTP to the direction of Hanoi. The latter is an interchange of which structure needs to be studied. Typical interchange types include the following:

- Cloverleaf interchange,

- Stack interchange,

- Roundabout interchange,

- Trumpet interchange,

- Diamond interchange, and

- Partial cloverleaf interchange.

Further study is necessary to determine the structure and design. It should also be noted that the structure and design should have only a marginal influence on UMRT Line 3, which may be designed and constructed later as a road or rail-based transport using the reserved zone within the right-of-way of the Lang-Hoa Lac Highway.

6 The interchange(s) can also be shared with the Phu Cat Industrial Park.


3-11


Figure 3.3-3 HHTP Internal and Zonal Road Development Plan


3-12

Number of lanes for the trunk roads which connect major gates of the HHTP is considered based on the traffic demand projection in Table 3.3-2. Assuming that the standard road traffic capacity of an urban area is approximately 12,000 PCU per day per lane, necessary number of lanes should be four lanes for 2012 (Phase-1) and six lanes for 2020 (Phase-2) including both directions. Although only four lanes will be necessary in Phase-1, it is preferable to provide enough room for the forecasted traffic from the initial stage especially as the main gateway to the HHTP. Thus, six-lane roads (Type I) are planned for these trunk roads (total length of 6.7 kilometers) from the initial stage (Phase-1). Furthermore, for easier movement of heavy vehicles such as trailer trucks, enough road width may be desirable for all internal roads. Hence, four-lane roads (Type II) are planned for the rest of the internal roads (total length of 15.1 kilometers).

Typical cross sections of a 50 meter-wide, six-lane road (Type I) and a 33 meter-wide, four-lane road (Type II) are exhibited in Figure 3.3-4. The width of Type I roads is the same as that of the widest road in the original master plan. Meanwhile, sectional composition of Type II roads is essentially the same as that of the second widest (i.e., 26 meter-wide) roads in the original master plan except that a 3.5 meter-wide buffer zone is added on each side of the road in order to secure underground space for utility pipes. Both types of roads are divided by a median strip which may be used for future rail-based UMRT lines (elevated structure). Sidewalks are also provided on both sides to ensure safety of pedestrians. In the case of a six-lane road, the rightmost lane may be physically separated to be dedicated for bicycle and/or motorcycle traffic, depending on the actual traffic situation.

(2) Zonal Road Infrastructure

All the roads in the HHTP except for the above-mentioned internal roads can be defined as zonal roads. Trunk zonal roads should be provided at the minimum from a road network point of view (both for transportation and for utilities) as shown in Figure 3.3-3. Those trunk zonal roads are defined as Type III roads which are 29 meters wide.

Total length of the planned zonal roads is approximately 10.1 kilometers. The rest of zonal roads are to be planned and constructed by a developer or tenant in charge of each zone or lot depending on the actual demarcation of land. Overall, approximate road density, which is defined as total road length per unit area, should be close to the standard road density for each land use zone presented in Table 3.3-3.

Typical cross section of a zonal road (Type III) is exhibited in Figure 3.3-5. Sectional composition of Type III roads is essentially the same as that of the third widest (i.e., 22 meter-wide) roads in the original master plan except that a 3.5 meter-wide buffer zone is added on each side of the road in order to secure underground space for utility pipes. Although this is the widest type of zonal road with four lanes, median strips will not be constructed for flexibility purposes. The road may be divided later by placing movable barriers depending on the traffic situation from roadside tenants or local roads. Sidewalks are provided on both sides to ensure safety of pedestrians.

(3) Transportation

In the HHTP master plan, it is important to make safe, comfortable road and transportation plans for all users including residents, visitors, workers, students, and heavy vehicles. In line with their major means of transport and their major destinations in the HHTP, proper separation of those different types of traffic should be considered. As such, it is preferable to limit the use of the main gate only to passenger cars that are used by visitors to and residents in the HHTP. In addition, trucks and trailers should use only the eastern sub-gate which is the closest to the High-tech Industrial Zone.

As for public transport, conventional bus services (except for company buses) should end at one of the three bus terminals that are planned beside the gates, and the passengers should take shuttle buses that are provided by the HHTP. For this, at least three shuttle bus routes are proposed. Each route should connect two of the three bus terminals and the routes should eventually cover most of the areas in the HHTP. Those shuttle buses should also serve as feeder bus services for future UMRT lines connecting with Hanoi.

3.3.4 Development Issues

(1) External Road and Transportation Infrastructure

Development of the HHTP cannot be fully completed without planning adequate external infrastructure which connects with outside the HHTP. As such, external road and transportation infrastructure can be defined as infrastructure which contributes to the development of the HHTP as well as the regional economy or public goods in the Hanoi Metropolitan Area. It may include several projects of arterial roads, transit systems, and transportation facilities that have been planned in Ha Tay, Hanoi, or some other province. Although such projects are not located within the HHTP, they are crucial for development of the HHTP. Thus, the following three road and transportation projects that were explained earlier are included in the external infrastructure:

- Lang-Hoa Lac Highway,

- Hanoi Ring Road 3 South (section between Lang-Hoa Lac Highway and National Highway 5), and

- Urban Mass Rapid Transit Line 3 (Hoa Lac-Ba Dinh route).

In addition, two more projects are considered as part of the external road infrastructure that has a great influence on the development of the HHTP, namely:

- Hanoi Ring Road 4 West (section between National Highway 2 and National Highway 1A), and

- Logistic Center for the Western Hanoi Metropolitan Area.

Locations of the above projects are shown in Figure 3.3-6. Updates of the last two projects are described below.

1) Hanoi Ring Road 4 West (section between National Highway 2 and National Highway 1A)

In the HAIDEP network, Hanoi Ring Road 4 (RR4) performs as the outer ring road in the urban road network, which aims to enhance the connectivity among suburban centers surrounding Hanoi CBD and to create a bypass around Hanoi, thereby minimizing the need for inter-provincial through traffic from entering the city center. Moreover, RR4 functions as a physical barrier to control urban sprawl, as it creates a boundary for the Hanoi urban growth region as proposed in the HAIDEP urban development plan for Hanoi. While RR3 runs in the urban area of Hanoi, RR4, which is located on the periphery of the Hanoi Metropolitan Area, is expected to serve as a more effective interface between urban and regional transportation in the long term. Without RR4, the future urban development orientations in HAIDEP would not be realized.

For this purpose, high level of service (i.e., high speed and access control) is required of RR4. Thus, it is proposed that RR4 should be developed as an expressway, initially with four lanes. RR4 proposed in HAIDEP is almost an entirely newly built road, except for sections overlapping NH2. In the HAIDEP urban transportation master plan, RR4, which is about 100 kilometers in length, is located around 15-20 kilometers from the city center and 5-8 kilometers from RR3.

RR4 West is the western segment of the fourth ring road of Hanoi proposed in the HAIDEP master plan, and is scheduled for operation by 2013. Pre-feasibility study of RR4 West was also conducted in HAIDEP. RR4 West starts from NH2 in


3-17

Noi Bai in the north and ends on NH1A in Thanh Tri in the south for a total length of 45.35 kilometers, traversing the boundaries of Hanoi, Vinh Phuc, and Ha Tay provinces. This segment, which is directly connected to Lang-Hoa Lac Highway, is also closely related as a more efficient regional transportation route from the HHTP northward to Noi Bai and south/westward to the national trunk highway (NH1) as well as the main ports in northern Vietnam. The role of this segment is expected to become even more important if a logistic center for the Western Hanoi Metropolitan Area, which is another external infrastructure for the HHTP, is developed on RR4 West.

HAIDEP suggests that a four-lane divided cross-section would be sufficient. The median will be enlarged to reserve space for additional two lanes for future expansion. In addition, frontage roads will be provided along the sides of RR4 West to offer access to developments along its corridor. As such, the typical cross section of RR4 West is 80 meters in width. RR4 West will feature six interchanges on NH2, NH23, NH32, Lang-Hoa Lac Highway, NH6, and NH1.

RR4 West is estimated to cost 639 million US dollars, which includes construction, engineering, contingency, and land. Land cost is 128 million US dollars or 20 percent of project cost. A breakdown of the total project cost per section is shown below:

- Package 1 (NH1 – NH6), 12.8 kilometers: 134 US million dollars,

- Package 2 (NH6 – Red River), 15.0 kilometers: 160 US million dollars,

- Package 3 (Red River Bridge including approaches), 7.1 kilometers: 235 US million dollars, and

- Package 4 (Red River – NH2), 10.5 kilometers: 109 US million dollars.

2) Logistic Center for the Western Hanoi Metropolitan Area

For freight transportation, in the HAIDEP master plan, a total of four logistic centers have been planned for north, south, east, and west of the Hanoi Metropolitan Area. All the four logistic centers, with services such as storage, consolidation, depot, customs clearance, and bonded transportation, have been planned along RR4, which is an important arterial road for the future of Hanoi in terms of both managing urban growth and establishing an effective interface between urban and regional transportation. Among others, the logistic center for the western Hanoi Metropolitan Area will be very important for the HHTP as freight to and from Hoa Lac should be transported through this logistic center.

In HAIDEP, location of the logistic center for the western Hanoi Metropolitan Area is planned beside RR4 near the interchange with NH6 as shown in Figure 8.3-4. Although this location may be good for connectivity with railway, the location is still tentative and it may be moved westward toward Lang-Hoa Lac Highway. In any case, this logistic center is expected to serve as a base for transportation of goods and commodities between the HTTP and the main ports in


3-18

northern Vietnam such as Hai Phong and Cai Lan and for other long-distance or international freight transportation. A detailed study will be necessary to select the site, determine the scope and size (including customs houses, banks, shipping company offices, inspection companies, and bonded warehouses), design the facility, and investigate its project feasibility of the logistic center.

The above-mentioned five external road and transportation infrastructure projects for the HHTP are summarized in Table 3.3-4.

(2) Other Infrastructure

The Northern Phu Cat Industrial Park (NPIP) with total development area of 1,507 hectares (1st phase: 307 ha, 2nd phase: 1,207 ha) is located on the south of the HHTP across Lang-Hoa Lac Highway. It is expected that supporting industries for the HHTP High-Tech industries should be located in this Industrial Park, and both HHTP and NPIP could share common external infrastructure such as Lang-Hoa Lac Highway. An interchange connecting the HHTP and the frontage roads of Lang-Hoa Lac Highway can also connect the NPIP. Hence, the development of the HHTP is closely related to the development of the NPIP.

The layout of the NPIP is shown in Figure 3.3-7. At present, about 250 hectares of the land for 1st phase has been developed and two factories (brick manufacturer and glass fiber reinforced pipe manufacturer) are operating and about 10 enterprises are under process of investment application according to VINACONEX. As for the eastern boundary road, it is currently under construction and will be developed as a provincial road. This 42 meter-wide road will also serve the reserved area for future expansion of the HHTP, which is located on the east of the NPIP. One of the planned interchanges/ grade separations for the HHTP is this location, connecting this road with Lang-Hoa Lac Highway and the HHTP eastern sub-gate as shown in Figure 3.3-3 (Location B).
