This week, the first autonomous vehicle in Canada made its entry on public roads in the South Shore of Montreal, Quebec. This 100% electric and autonomous shuttle will be on a pilot period for 12 months allowing passengers onboard until the end of Fall. Due to Quebec’s harsh winter conditions, the shuttle will be passenger-less […]Read more
The Jacques Cartier Bridge: Gathering and analyzing traffic data for prevention, action and innovation
For many years now, traffic on the island of Montreal has gotten increasingly complex, with countless roadwork sites fanning the flames of the situation. With the building of a new Champlain Bridge and work planned for the Louis-Hippolyte-Lafontaine Tunnel, the company managing two city bridges, Jacques Cartier + Champlain Bridges Inc. (JCCBI) wanted to analyze traffic flow data to measure the surplus on the Jacques Cartier Bridge and create a suitable management plan that would minimize the impacts on fluidity and safety on the road network.
An important point to consider: The Jacques Cartier Bridge is a key structure in Montreal, with five lanes over 2.7 km. It is taken by thousands of users every day to cross the St. Lawrence River between the city and its south and the north Shores.
The solution proposed by Orange Traffic
Counting and classifying vehicles
As requested by JCCBI, Orange Traffic has combined existing loop technologies using PEEK ADR counters at the bridge entrances and exits with six new strategically located Wavetronix SmartSensor HD radars. Data from the two types of devices are combined and analyzed by the Command software, which can produce reports analyzing various aspects of the traffic flow: number of vehicles, length, speed, direction, space between vehicles, roadway occupancy, etc.
Smooth traffic flow
Close to 100 lane control signs are installed on the bridge to enable the opening and closing of lanes according to traffic intensity and direction. This equipment not only keeps traffic flowing smoothly but also allows some lanes to be closed in emergency situations.
Four Wavetronix SmartSensor HD radars are used to measure traffic density and average speed. This information is sent to a Click 513 (Wavetronix traffic alert device), which analyzes the data and sends a signal when congestion conditions are met. Drivers are then advised of the upcoming congestion on flashing panels warning them to “prepare to stop.”
Data in the service of an innovative project
In addition to improving flow and safety on the bridge, the information gathered by Command is also used to provide valuable data to the Jacques Cartier Bridge illumination project. This spectacular light project is part of the celebrations for Montreal’s 375th anniversary. See this article for more details.

It was in 1988 that Orange Traffic entered the directional signaling market; lane control, left or right turns, traffic lights for pedestrian crossing. The basic philosophy has always been to dedicate time, energy and funding to promote research and development. Innovation is essential to achieve this philosophy and it is defined as the action to […]Read more
