Traffic flow

When construction works affect the arterial or local traffic network, traffic management plans are prepared to help minimise impacts to road users. Where possible, the PTP Alliance schedules road-impacting activities outside of peak times and minimises the duration of temporary road and lane closures.

Traffic management strategies

To ensure the safety of pedestrians, motorists, cyclists and workers during the project, various forms of traffic management will be in place including:

  • Reduced speed limits
  • Road, lane and pathway closures
  • Road diversions and construction of temporary roads
  • Road barriers and fencing around the construction zone
  • Temporary traffic signals and stop-slow traffic controllers
  • Static signage
  • Temporary bus-stop relocations
  • Temporary parking restrictions
  • Changes to pedestrian and cyclist access.

Communicating traffic changes

Wherever possible, advance notice is provided to the community about traffic changes in a number of ways, including:

  • Variable message signage and static signage
  • Email notifications to stakeholders and road users
  • Information on Department for Infrastructure and Transport and PTP Alliance websites
  • Department for Infrastructure and Transport social media updates
  • Advertisements in local newspapers and on the radio.

Traffic conditions progressively change during construction, and we ask that commuters are alert, patient and pay close attention to road signage. Where possible, plan your journey in advance and allow a little more travelling time.

Traffic management liaison groups

The PTP Alliance uses regular traffic management liaison group meetings with key stakeholders including Department for Infrastructure and Transport, the Traffic Management Centre, Adelaide Metro, emergency services, and local councils.

Traffic management liaison groups allow key stakeholders to discuss and contribute to the planning and implementation of traffic management throughout the project. Key discussion points include:

  • Safety
  • Community feedback
  • Timing of major traffic switches
  • Status of traffic operations and performance
  • Coordination with other nearby works and events
  • Emergency service access
  • Communication planning for future works.

Pedestrians and cyclists

Temporary fencing, road barriers and signage are used during construction projects to delineate construction zones and ensure that motorists, cyclists and pedestrians can safely navigate around works sites. As works progress and access routes change, signage and notifications are used to advise pedestrians and cyclists of any detours.
