Intelligent Transportation Systems

The Port Mann/Highway 1 corridor makes use of the latest Intelligent Transportation Systems to help keep the highway safe, efficient and fast for customers.

Technology and sensors along the corridor monitor live traffic conditions. They gather information about traffic flow that can help responders reach drivers and passengers in need, and help drivers get to where they need to go quickly and safely.

140 sensors along Highway 1 between Langley and Vancouver measure speed, traffic flow and density. This information is compiled, in real-time, and is used to calculate travel times, which are displayed on the overhead message boards.

This system helps drivers plan their routes. On a typical morning, it might take 19 or 20 minutes to get from Cape Horn to Hastings Street, for example. If the information boards show it’s taking longer, that could mean there’s a back-up somewhere along the route. A driver can look at the travel times to Grandview, or earlier exits. If those travel times look typical, the congestion is further along and the driver may choose to exit there and avoid the congestion. This information keeps drivers informed, and utilizes the road networks to their fullest potential.

In addition to the sensors and signs, every section of the highway is monitored by camera. This allows operators to monitor traffic flow and quickly detect incidents, at which point crews can be dispatched.

Seismic sensors on every improved bridge and overpass along the Highway 1 corridor monitor key structures to provide their seismic strength. Following an earthquake, the sensors feed into the BC SIMS ( British Columbia Smart Infrastructure Monitoring System), an important piece of British Columbia’s post-earthquake response program.

These intelligent systems and teams work together so TI Corp can monitor and manage traffic on the PMH1 corridor, and make evidence-based decisions to improve operations and safety.
