A5.8.5 Responsibilities of STMS on level 2 & 3 roads

When the level 2/3 STMS must be onsite The STMS must be present at an attended worksite at

all times except during a drive through when the STMS may need to leave the worksite to gain access to the front of the worksite.

In this case the STMS may be away from the worksite for up to 30 minutes.


Exceptions to this rule are as follows: An STMS is permitted to control up to four attended

shoulder closure worksites on level 2 and level 3 roads at any one time subject to the following: o an STMS remains within 30 minutes of all worksites o a person with a minimum qualification of STMS-NP is present

and takes charge of TTM at each attended worksite o that STMS-NP must have been briefed by the STMS and the

briefing documented o the STMS must be present for the set up, alteration and

removal for each of the worksites.


Mobile operations on level 2 roads On level 2 roads where all activity is at least two metres

clear of the edgeline, an STMS-NP may take the role of an STMS and set up, maintain, alter and remove TTM under the following conditions: o the STMS must brief the STMS-NP in charge of the operation

on the TTM requirements o all the above actions must be documented by the STMS.

A5.9 Traffic controller

The lane closure sign requires a supplementary sign displaying the distance to the lane closure.

Depending on worksite requirements, the first lane closure sign is placed at least one sign spacing in advance of the start of the taper.

For multiple lane closures, the second lane closure must be signed at least one sign spacing in advance of the start of the second taper.

Multiples of 100m may be used instead of the sign spacing.

C8 Lane closures

Centre lane closures are not permitted Exception: A level 1 road (not a state highway) with permanent speed of 50km/h or less.

In this exception only, centre lane closures are permitted provided: traffic merges only in one direction there is a definite lane shift (either left or

D1 General

Mobile closure A normally continuously moving activity or work

operation carried out within the road reserve that may also stop briefly at a particular location for a period of no more than 10 minutes. Note: Activities like mole ploughing and drain digging move along the road but they move too slowly to be considered mobile operations. These types of activities must be planned and managed as static operations.

D1 General

Semi-static closure A short term activity or work operation that is carried

out on the carriageway of a road at a particular location that takes more than 10 minutes, and less than 1 hour, to complete. Note: The 10 minutes to 1 hour timeframe applies only to the working period and does not include the time required to install and remove the TTM devices on the worksite. No work is to be undertaken during set-up or removal of TTM equipment.

D1 General

Special operations These are mobile operations which may vary the

requirements of the above two categories or provide additional requirements to enhance safety for certain situations

Included in this category are: o inspections o kerbside collections o road marking o rolling blocks.

D1 General

TV2 (TW-26) road works sign

If lead pilot vehicle not required, the TV2 (TW-26) sign is only required on the lead working vehicle where the speed limit is greater than 65km/h

Signs on cars or light utility vehicles Where cars or light utilities are used (for inspections, sports

events and high speed data capture) only the appropriate supplementary sign will be required

Signs on work vehicle more than 5m from edgeline

Where the work vehicle is more than 5m from the edgeline the work vehicle must have either:

the appropriate advance

warning sign with supplementary plate if required and the RD6R (RG-34) sign

or the TV4 (TW-34) PASS WITH

CARE sign and the RD6R (RG-34) sign.

D1 General

When RD6L/R (RG-17/34) signs can be omitted from the TV4 (TW-34) Pass with Care sign Where the situation is constantly changing (eg rolling,

grading, road marking, water cart, drag brooming operations on two lane one way roads) and it is impractical to change the RD6L/R arrow frequently, it may be omitted

D1 General

LAS operation now included in this section Caution mode lane closed

A part of the roadway which is used for driving is closed and it is unsafe to pass.

Note: Downward or upward pointing arrows are currently not gazetted signs and MUST NOT be used

Downward or upward pointing arrows must not be visible when TMA is not engaged in traffic management

D1 General

Use of AWVMS added to this section The AWVMS replaces the need for a tail

pilot TMA vehicle

Using an AWVMS is optional for most RCAs. However on level 2 and 3 state highways their use is mandatory (from 1 July 2012).

The maximum allowable separation from an AWVMS to a shadow vehicle TMA is 1600m (this distance may be extended from 1600m to 3km if there is no available shoulder width for the AWVMS within 1600m of the next working vehicle).

D2 Work vehicles

Mobile operations – rotating role of vehicles on level 2 and 3 roads Contractors are expected to use:

o AWVMS or pilot vehicle(s) to provide advance warning o shadow vehicles fitted with TMAs, and o work vehicles

The roles of the vehicles may be rotated if the work vehicle is a TMA truck

No workers are allowed on the back of the AWVMS, pilot and/or shadow vehicles

The full complement of vehicles must be maintained

Operating mobile operations within an established static worksite

Where a mobile operation is contained completely within an existing fixed static worksite which has: o advance warning, and o direction and protection signs, including approved TSL sign(s)

installed o CSD available to the work vehicle at all times

the requirement for a tail pilot vehicle for any mobile operation within the worksite is waived.

All other requirements for mobile operations with respect to shadow and work vehicles must still be applied.

Summary of level 1 distances for level 1 mobile operation

Summary level 1

D5.1.1.1 Specific requirements for level LV low-risk mobile operations

For Mobile operations on level LV / Low risk roads with permanent speed less than 65km/h utilise rear mounted: o T1 (TW-1) type signs, or o TV4 (TW-34) PASS WITH CARE sign and the RD6R (RG-34)

sign.

Each vehicle has at least one (preferably two) amber flashing beacon(s).

The minimum rear CSD required is: o 3 x the permanent speed limit, or o 75m on non-state highways less than 55km/h.

If the above requirements cannot be achieved the operation must be modified to comply with the requirements of a higher risk rating.

D5.1.1.1 Specific requirements for level LV Low-risk mobile operations

Requirements where permanent speed less than 65km/h: Signs on vehicles either:

o T1 (TW-1) type signs, or o TV4 (TW-34) PASS WITH CARE sign and the RD6R (RG-34)

sign.

Each vehicle has at least one (preferably two) amber flashing beacon(s).

The minimum rear CSD required is: o 3 x the permanent speed limit, or o 75m on non-state highways less than 55km/h.

If the above requirements cannot be achieved the operation must be modified to comply with the requirements of a higher risk rating.

Cone tapers when an AWVMS is used

(Amendment to D6.1.2 Worksite layout and D6.1.3.4) Where an AWVMS is used as the advance warning

and direction and protection sign for the semi-static closure there is no requirement to place a cone taper to the rear of the shadow vehicle.

Amendments have been made to the following TMDs: o G2.14 o H3.1 o H3.2.

D7 Special activities

Road marking – covered in section D and industry best practice TMPs are available in section I

Kerbside collections - covered in section D and industry best practice TMPs are available in section I

Requirements for repairing a flexible median barrier have been added to section D

Requirements for rolling blocks have been added to section D

D7 Special activities - Inspections

Inspections and non-invasive works Includes:

o observation, using a measuring wheel, surveys, traffic counts, o installing traffic count equipment, o road maintenance activities such as removal of litter, cleaning

signs, cleaning edge markers, installing edge marker posts, temporary pothole repairs, hand clearing vegetation from culvert headwalls and inlet /outlets or taking photographs.

More complex activities, or those which cannot immediately move off the live lane, require mobile or static TTM

Type of road On Shoulder – no time limit

On live lane up to 5 minutes

On live lane for more than 5 minutes

Level LV One person activity. STMS or TC qualified inspector working under a TMP prepared by a STMS – Inspector must be briefed by a STMS. STMS or TC must be on site at all times. Level 1

Two person activity. STMS or TC qualified inspector working under a TMP prepared by a STMS – Inspector must be briefed by a STMS. STMS or TC plus lookout/spotter must be on-site at all times.

Level 2 & 3 STMS – NP on site and in control of activity at all times.

Mobile, semi-static closure or static fixed site closure required.


General rules

Inspectors must move to avoid traffic. They must not expect traffic to move or slow down to avoid them

On busy roads avoid peak periods or use a higher level of TTM

Crossing a level LV, 1 or 2 road does not constitute being on a Live Lane

Crossing a level 3 road does, unless a pedestrian crossing facility is being used


Vehicle

Advance warning (inspection vehicle fitted with one and preferable two amber flashing beacons and a rear mounted sign indicating the type of activity taking place) must be positioned in advance of the inspection site

A vehicle is not required on a level 1 road with a permanent speed of less than 65km/h

An amber flashing beacon is not required on an unsealed shoulder (including footpath) of a road with a permanent speed of less than 65km/h


Spotter

A spotter is not required on LV roads

Where no LV roads have been designated, the RCA can select level 1 roads for ‘single inspector’ inspections

Where an unaccompanied inspector is not able to maintain adequate attention (for example, due to work tasks, or poor visibility), a spotter will be required or another type of traffic management operation used
