PREFACE

Bengbu, 33°01’～32°49’N and 117°31’～117°11’E, a municipality directly under leadership of Anhui province is an important industrial, commercial and high tech city in north Anhui. Since it is located at the significant joint of Jinpu Railway and Huaihe River, it is also the hub of highway and waterway. As one of the major cities along Jinghu High Speed Railway, the high speed railway zone development will be the a hard to obtain historic developing opportunity for Bengbu, thanks to the significant combined advantages of the costs of land, labor, office and transport, and the landscape and traditional industrial and scientific research foundations.

Nowadays, in Longzi Lake District of Bengbu City, the urban infrastructure of the systems of drainage, the supplies of water, power, gas, and telecommunications and roads are not perfect; the rainwater and sewage are directly discharged into Longzi Lake and Baojiagou Ditch and finally into Huaihe River through underground infiltration, as a result, to deteriorate Huaihe River water quality. According to the special drainage plan of Bengbu, the rainwater system of Gaotie area in Longzi Lake district belongs to Longzi Lake and Baojiagou Ditch water division sub-area, the rainwater is discharged into Longzi Lake and Baojiagou Ditch firstly through the collection with rainwater Subsurface Networks; the sewage system being of Yangtaizi sewage system, the sewage is first collected with sewage Subsurface Networks, then lifted by the pump stations at Tanghe Road and Shenglidong Road and finally enters into Yangtaizi Sewage Plant and discharged into Huaihe River after the water quality up to the standard.

To improve the water quality of Longzi Lake and Baojiagou Ditch, and eventually that of Huai River, and to improve the infrastructure of Longzi Lake District, Bengbu Investment Group Co., Ltd is planing to build Lilou Road (2609.3m) and Fengandong Road (2813.24m). The subsurface networks for Lilou Road is 2.6km, and 2.8km for Fengandong Road.

In compliance with the related national EA laws, regulations and World Bank safeguards policies, the “Environmental Impact Assessment of the Project of Constructions of Lilou Road and Fengandong Road and Their Subsurface Networks in Longzihu District (Draft Delivered for Examination)” was worked out in Mar. 2012. On Mar. 31, 2012, an expert panel was invited by Bengbu Municipal Environmental Engineering Assessment Center to exam the statement. According to the comments of the experts, some necessary revisions and supplementations were done by our institute and worked out “Environmental Impact Assessment Of The Constructions Project Of Lilou Road And Feng’andong Road And The Main Subsurface Networks In Longzihu District (Draft Delivered For The Examination And Ratification)” and is now presented to the superior competent authority for the ratification. The report has been updated based on World Bank comments in order to meet World Bank relevant safeguards policy requirements.

2.4.2 The Conformity Analysis for Bengbu Urban Comprehensive Traffic Plan

In the main city plan, the road network takes Huaihe River as natural axis and the road is basically distributed in paralleled and vertical ways to the river. Since it is separated by the river, there is unbalance economic development between the main city area and that of northern riverside; the traffic across the river is considerably poor and the facilities across the river needs also to be improved. With the strategy decided to by the municipal Party committee and government to extend the city scale and stepping over the river in Mar. 2004, Huaishang District was established in the old city area north riverside to make the city planning road network become the “one ring-four lateral-three longitudinal” pattern.

The “one ring” means to form Feihe Road, Laoshan road, Nanwaihuan Road and Daqing Road as quick route shaping ring type quick traffic to improve urban developing space and transit passage transport, perfect urban communication environment and lay a solid foundation for city expansion.

The four-lateral-three-longitudinal” pattern means the main road system to secure the city interior space connection, in which “four lateral” means Huaishang Avenue, Shengli Road, Donghai Avenue and Huangshan Avenue; the “three- longitudinal is the Chaoyang Road-Fengyuan Avenue, Jiefang Road and Gaotie dong Road.

The Lilou Road and Fengandong Road to be newly built are the planned city main roads, the details refer to Fig. 2-4-1 – Overall Traffic Plan Map of Bengbu City.

4. Road Foundation Design

The road foundation shall be constructed in layers and rammed evenly; the road foundation compactness adopts heavy tamping standard: the detail see Table 3-4-1. The compactness of pipeline grooves within the road foundation is equal to the road foundation tamping requirements; the modulus of resilience of top of the road trough shall not less than 30MPa.

Note: The figure in the table is heavy tamping standard; the denominator is light tamping standard.

This road foundation designed filling road section embankment side slope is of natural slope at 1:1.5, the digging road section embankment side slope is of natural slope at 1:1. When the road embankment extends through ponds and rivers, the normal water level + 0.5m below to water bottom side slope is at 1: 1.75, that approaching water level shall be sealed with mortar masonry protection of the thickness not less than 0.6m; the normal water level + 0.5m above road foundation design elevation side slope is 1:1.5.

As for the ditches and ponds which road extends through, when the mud thickness is less than 2m, the mud shall be first removed and then the road foundation built, each tamped layer thickness shall be less than 30cm; in case mud is more than 2m, first remove the mud (1.5m down to top), squeeze the mud with rock blocks (diameter more than 30cm), then fill and build the road foundation and finally do the overload pre-compaction (1m high and pre-compactness for more than 1 month).

5. The Design of Road Intersection Connection

(1) Design Principle

① Meet the requirement of overall transport function and the urban planning construction areal service;

② Further analyze and study the planned road network, determine reasonably current plane intersection type and road traffic organization etc. and settle well diversified vehicles’ demands over the traffic to meet the areal traffic functional demands;

③ Select the technical index for plane crossing canalization design reasonably, secure driving safety, furnish satisfied direction identifying and eliminate various factors causing drivers to make mistakes;

④ Do the crossing canalization design for the main intersections which mainly depend on traffic volume forecast. After the calculation of the intersectional traffic capacity, lanes expansion design of the entrance and exit of main intersectional crossing can be done to compress central isolation belt width, widen redline width; traffic signal lamp control shall be used for main road crossing with sub-main road; when branch road meets main road and sub-main road, the vehicle driving discipline of “main road in priority” shall be carried out, i.e. when the vehicles running on main and sub-main roads, the vehicle on branch road shall wait and enter into main road until those on main road pass first.

(2) Canalization Design of Plane Intersection

① Since the traffic capacity of intersections is less than road section, in order to enhance traffic capacity of intersection, the design measure of increasing lanes numbers shall be used. As for the main-main intersections in the design, the division lines and physical division islands shall be arranged in terms of crossing types and special right/left turns lanes shall be widened in road’s entrance and the straight lanes remain same, at the exist, a lane combined with public bus bay shall be widened for right turn acceleration; that shall not be widened as the main-sub-main road and main-branch roads.

② The all line opening intersection uses traffic signal lamps control; when the auxiliary road’s main roads meets sub-main/branch roads, the semi-closed crossing shall be applied to organize the traffic, i.e. when vehicles need to enter into sub-main road, they shall first go from fast lane and turn right into auxiliary road, then go out in right turn from auxiliary road and enter into main road so as to approach the fast driving out; when vehicles need to enter into main road, the vehicles on sub-main road shall go in right turn into the auxiliary road of the main road and then go into fast lane from the auxiliary road so as to realize the fast leaving.

③ The U turn lane designed in the intersection and marking guide installed on oncoming lanes will guarantee traffic safety.

(3) The Specific Design of Intersections

① Design of Pedestrian Crossing

Since the intersection is wider and pedestrian cross is longer, in order to secure the pedestrians safety, the marking canalization safety stop zone in central junction green belt is designed. This projected stop zone has central division belt, which is the same width with pedestrian crossing and its road surface is paved with tiles.

② Length Expansion Design for Entrance and Exit Lanes

In this project, a left turn and right turn special lanes each are added to the main-main road intersection, the lanes gradual change section is 40m long, left turn ex
