Halifax to replace legacy traffic control equipment

Traffic on the Halifax Peninsula in Nova Scotia, Canada, is set to become less congested after the deployment of a proposed new traffic signal control system. This week, the Halifax Regional Council will consider a recommendation from its audit and finance standing committee to award a C$3.2m (US$2.9m) contract to Delcan to install new traffic control equipment after the company emerged from the bidding process with the highest-scoring technical and cost proposal. The replacement of the existing traffic signal control system forms the largest sector of a C$4m (US$3.6m) project to improve the flow of traffic through peninsula intersections, which will also include appointing a systems integrator to oversee the work.

Halifax’s peninsular region has 91 intersections that are equipped with outdated and non-functional legacy traffic control technology. Originally installed in 1990, the existing SCOOT traffic control system is based on the SCOOT (Split Cycle Offset Optimization Technique) methodology, but suffers from deteriorated and obsolete equipment that can no longer track or reflect live traffic signal data. In its tendering and procurement report last year, the Halifax Regional Municipality, said, “With the SCOOT system no longer operational, the signalized intersections that had been under its central control have reverted to local control, with many operating under outdated preset, fixed time-of-day plans.” The city is keen to upgrade technology that requires traffic lights to operate under driving patterns that were established in the 1990s, and fail to reflect changes in current traffic patterns or the increased number of vehicles on the road.

Deploying a system based on Delcan’s Intelligent NETworks ATMS (Advanced Traffic Management System) will, “improve mobility for the public by reducing vehicular delays through intersections and reduce related greenhouse emissions,” according to the report. The new traffic control system will also be equipped with specific modules that are designed to improve safety for visually-impaired people and provide bicycle detection equipment. The ATMS will also be equipped with a cellular-based communication system that will provide public transit and emergency vehicle priority, as well as real-time intersection monitoring and control.
