Plan Preparation

 

Workzone and Event Traffic Management Plan Preparation

The Guide to Preparation of Traffic Management Plans (see below) has been prepared primarily to assist the preparation of submissions to conduct works on roads that are under the care, control, and management of MRWA and may be used for arterial roads under Local Government control.  It generally meets the Traffic Management requirements of MRWA Specification 202 "Traffic". 

Traffic Management Plans (TMPs) for roadwork sites provide a means of planning and implementing how all likely road users will be safely and efficiently guided through a roadworks site and ensure the network performance is not unduly impacted, for the duration of the works.  TMPs are prepared in advance of the works being conducted and are generally subject to auditing before and/or after implementation.

Traffic Management is the management of occupational safety and network performance risks associated with work activities undertaken in a traffic environment.  Risk Management and the elements of the risk management process form the basis of this Guideline.  In Western Australia (WA) TMPs are prepared and implemented by those who have gained relevant accreditation under the Main Roads Western Australia (MRWA)’s training programs.  To prepare, review or audit TMPs involving complex traffic arrangements, Main Roads requires use of an accredited Roadworks Traffic Manager (RTM).
All TMPs shall be based on the requirements of the current MRWA Traffic Management for Events and or Works on Roads Code of Practice (the Code of Practice). The Code of Practice supplements the Australian Standard AS 1742.3, however, it also outlines additional requirements and variations from AS1742.3 applicable to WA.

For works undertaken through contract for Main Roads, the MRWA Specification 202 “Traffic” provides information to contractors about Main Roads’ specific requirements in developing a TMP.

Commonly used Terms and Definitions

Traffic Control Diagram (TCD):  Is a diagram that depicts the positioning of signs and devices arranged to warn traffic and guide it around, past or if necessary through a work site or temporary hazard. The TCD details the location, spacing and sizes of all signs and devices, the location and lengths of tapers, all pavement markings and delineators, any containment or safety fencing, flashing arrow signs, portable traffic signals, variable message signs (VMS), roadwork speed zones and if necessary, pedestrian, workers and vehicle routes.

Traffic Control Guidance Plan (TCGP):  Same as Traffic Control Diagram (TCD) but may also consist of written instructions and guidance to explain procedures or arrangements associated with the control of traffic.

Traffic Control Plan (TCP):  Same as Traffic Control Diagram (TCD).

Traffic Management Plan:  That part of the proponents management plans which outlines the control measures for hazards associated with the traffic environment.  The TMP also documents strategies to manage impacts created by works activities on the broader road networks especially its impact on public transport and passengers, cyclist, pedestrians, motorist and commercial operations. It also describes how these impacts are being addressed.  This is through the use of detailed Traffic Control Plan (TCD), Vehicle Movement Plans, and Pedestrian Management Plans.

Vehicle Movement Plans (VMP):  Forms part of the TCD that show the preferred travel paths for vehicles detoured around or through a work site and vehicles associated with a work site entering, leaving or crossing through the traffic stream. A VMP also shows the travel paths for truck at key points on route remote from the works site such as places to turn around, accesses, ramps and side roads.

How to prepare a traffic management plan

This Guide is intended to provide general information about the components and format of a TMP.  It does not provide technical information on how to prepare a TMP.  Such technical information should be obtained by accredited practitioners, by referring to the Code of Practice, AS1742.3 and other related documents. 

For some non-complex works on low volume low speed local roads the below Basic Worksite TMP template may be used (see section 5 for full checklist).

    Note: the Road Authority may determine that a more detailed TMP is required.

 

Reviewing and Auditing Traffic Management

The below checklists are intended to assist personnel to prepare, review, audit and approve traffic management schemes. The checklists should be used as a guide only and used in conjunction with AS 1742.3, Traffic Management for Works on Roads Code of Practice and other related documents.

Suitability Audit: A systematic and independent audit of the TMP, by a RTM, prior to implementation.

Compliance Audit: A systematic and independent audit of the traffic management requirements, by a RTM, after implementation of the TMP.

Suitability Check: A check of the traffic management plan to ensure it addresses the specified requirements of the works, all types of traffic and the road environment. Done prior to TMP approval by the Road Authority.

Operational Check: An onsite drive through and check of the operation of the traffic management scheme, ensuring it is operating as intended at all times of the day (particularly at peak times). This check focuses on road efficiency, traffic delays, road user compliance/provisions and any incorrect visual cues. This should be done by the project team to ensure the TMP is operating safely and efficiently as intended, this is particularly important when the traffic management schemes change (e.g. different stages and/or after care).

Onsite Inspection: A frequent inspection of the traffic management once it has been implemented onsite. This inspection entails checking the signs, devices, method statements, and workers accreditation have been correctly applied onsite. This ensures the TMP has been correctly implemented.

The below checklist can be used for either an Operational Check and/or an Onsite Inspection as a guide to assist personnel.

 

TMP Authorisation Checklist for Local Governments and Authorised Bodies: This checklist details the minimum review local governments and other bodies with an Instrument of Authorisation should undertake before authorising traffic management on their network.

 

Generic Work Zone Traffic Control Diagrams (TCD's)

The below TCDs are intended to provide guidance for personnel engaged in common minor improvement and general maintenance activities. The purpose of the generic TCDs is to ensure consistent application of traffic management across the state.

Note: Prior to using these TCD's a Traffic Management Plan (TMP) is required, the author of the TMP will need to check that the TCD's are applicable to the particular work sites prior to signing off the TMP and TCD's.

 
Two TCDs have been prepared for each work type when using temporary traffic management signs; one using Australian Standard 1742.3 stand-alone signs and one using Multi-Message Signs (MMS) allowable under the Traffic Management for Works on Roads Code of Practice.
