Working in the Road Corridor - Temporary Traffic Management

Link to BeforeUDig website.This page describes the nature and extent of the Temporary Traffic Management (TTM), and how road users (including pedestrians and cyclists) will be managed by the use of TTM measures.

TMPs are required for all activities that vary the normal operating conditions of a road, irrespective of whether the activity is on a carriageway, on a footpath, or on a road shoulder.

Who needs a Traffic Management Plan?

1. If working anywhere in the Road Corridor, that will affect normal traffic movements, you need to organise Temporary Traffic Management (TTM),which details the measures to ensure safety for all people.

2. Having an event e.g. a parade, marches etc within the road corridor or an event not within the road corridor but may have a direct effect on the normal traffic movements e.g. sporting/entertainment events, school galas etc.

Normal traffic includes all road users; pedestrians, cyclists and motor vehicles.

If you have any questions or need assistance, please contact the Council’s Customer Service Centre by phone (04) 237 5089 – ask for the Road Protection Team or email enquiries@pcc.govt.nz.

The Road Corridor is by definition, all the land from property boundary to property boundary, including the footpath, berm, carriageway and accessways vested in the Council.

The Temporary Traffic Management (TTM) must be in accordance with the New Zealand Transport Agency (NZTA) Code of Practice for Temporary Traffic Management (COPTTM): Part 8 of the Traffic Control Devices Manual (TCD Manual) November 2012.

In terms of COPTTM, all the roads under the control of the Porirua City Council as the Road Controlling Authority (RCA) are all Level 1 roads. The RCA has a statutory duty to ensure the safe and efficient operation of the roading network under their authority.

Traffic Management Plans (TMP’s)

Traffic Management Plans describe the nature and extent of the Temporary Traffic Management (TTM), and how road users (including pedestrians and cyclists) will be managed by the use of TTM measures.

TMPs are required for all activities that vary the normal operating conditions of a road, irrespective of whether the activity is on a carriageway, on a footpath, or on a road shoulder.

TMPs are also needed for activities outside the road reserve, which will affect the normal operating conditions of the road.

Depending on the size, duration and location of the worksite or activity, TMP’s may be required for various stages of the work or activity. For example:

  • Mobile operation to set up TTM - preparing the site for works;
  • The static attended stage - workers on site;
  • The static unattended stage - no workers on site;
  • Mobile operation to remove TTM - completed works.

The Code of Practice for Temporary Traffic Management (COPTTM): Part 8 of the Traffic Control Devices Manual (TCD Manual) can be found on the NZTA Website.

Important Note: TMPs must be prepared by a qualified Site Traffic Management Supervisor (STMS),  who can be found under Traffic Management Services, in the Yellow Pages (electronic or hard copy)  The TMP is then submitted to Council by the STMS for approval or included in a Corridor Access Request (CAR). The any fees for the STMS will be over and above any Council fees.

A copy of the Council approved TMP must be held on the work site for the duration of the project and be available for checking by a Porirua City Council traffic management auditor.

Events and Traffic Management Plans

All events taking place within the road corridor will require a Temporary Traffic Plan. In addition, where an organised event is not in the road corridor but where the surrounding road network may be affected by a larger than normal vehicle or pedestrian movements, a Traffic Management Plan may still be required. e.g. School gala or a sporting event.  This does not include a “Temporary Road Closure”.  

The responsibility rests with the event organiser to liaise with Council to ascertain what TMPs may be required.
