Temporary Traffic Management
The majority of SCIRT work is not about the roads at all; most roadworks are to allow us to access underground services that are often located in the road corridor.
Once the underground services are fixed, the road will be closed up again. Most roads throughout the city will be partially repaired or patched rather than fully reconstructed. Full reconstruction will apply only where necessary.
Temporary traffic management (signs, cones, barriers and fences) helps keep road workers and road users safe.
Careful thought goes into all traffic management decisions. SCIRT works with Council, NZTA and CERA to understand the traffic impacts for each worksite and also the combined impact of all worksites across the network. Detailed street level programmes are fed into a traffic model to help sequence the work. SCIRT liaises on a daily basis with the Christchurch traffic operations centre (CTOC) based at Council offices in Hereford Street to ensure that the network is optimised to accommodate our work.
The www.transportforchristchurch.govt.nz website provides information about traffic changes across the city. There is also a mobile version of the site and links to iPhone and Android apps.
Traffic Management Plans
For each work site, we design and follow a Traffic Management Plan (TMP). Developing and carrying out TMPs is strictly managed. Qualified Site Traffic Management Supervisors (STMSs) follow a process very carefully. They need to thoughtfully balance many factors, including:
- other work sites nearby, and any combined effects on smooth flow
- different kinds of vehicles: cars, trucks, buses, emergency vehicles, as well as more vulnerable users like motorcycles, bicycles, and pedestrians
- physical conditions of the approaching road(s): curves, slopes, surface, features like bridges
- the placement of materials and also equipment when it is parked
- noise and vibration impacts
- signage and warning requirements as well as the need for traffic cones or other types of barriers
- existing speed limits
- how busy the affected road is and how practical it is to use alternate routes.
You can also help us get the work done quickly and safely by observing some basic guidelines when you're around our work areas.
