The operation of the traditional traffic sign is based on the peak of the morning and afternoon traffic, the peak time interval, and the default time interval to switch the signal. The lack of flexibility may limit the expected effect of the traffic. In order to reduce road congestion and improve traffic, Toronto, Canada will launch a pilot program to install and test two advanced Responsive intelligent traffic signs, which can monitor actual traffic conditions and switch signs in real time to improve traffic flow.
According to reports, Toronto has focused on improving transportation and commuting time for the past three years. The mayor announced that he will install two reactive intelligent traffic signs at 22 intersections at Yonge Street and Sheppard Avenue East. Switch time between flexible traffic signs, improve traffic flow, reduce vehicle red light pauses, fuel consumption and traffic delays.
On the Yonge Street section between Yonge Boulevard and Castlefield Avenue, a total of 10 intersections will be installed with new signs, and the control of the new number is run by the InSync technology already used in the United States, by analyzing the images detected by the cameras ( Video-analysis camera detecTIon), to identify the traffic conditions at the intersection, to measure the length of the vehicle that is waiting for the change of the number to pass the intersection, as the basis for the switch.
On the Sheppard Avenue East section between Neilson and Meadowvale Roads in Scarborough, there are also 12 new intersections at the intersection, and the new slogan is running SCATS in Australia, Asia and the United States. (Sydney Coordinated AdapTIve Traffic System) technology, through the radar to monitor the traffic flow to and from the intersection, as the basis for the switch.
Due to the lack of real-time detection of traffic conditions and computing power, traditional traffic signs cannot respond to actual traffic conditions at intersections. Both InSync and SCATS technology use the Adapt algorithm to optimize traffic flow in real time to reduce traffic jams and delays at intersections. The system can dynamically adjust the switching time of each intersection according to the traffic volume at the intersection to smooth the traffic flow along the road.
The mayor of Toronto pointed out that the new intelligent traffic signs can communicate with each other. When the traffic volume at the intersection is low, each number can flexibly adjust or synchronize the switching interval of neighboring related symbols according to the real-time traffic conditions. It can greatly shorten the waiting time for vehicles to wait for green light and improve traffic flow. The installation of the new sign for the 22 intersections will be completed in a few weeks, and each intersection will cost about $100,000 to $150,000.
People in the City TransportaTIon department will use the new Count Station, Bluetooth Detector, and commercial GPS data provided by the transportation data sharing company HERE to calculate traffic. Traffic and travel time information as a measure of the performance and effectiveness of the new logo. After the pilot program for the next year, the city will compare the differences in cost, traffic flow, and time-to-vehicle changes between the two technologies, and select the most cost-effective technology for the city and implement large-scale implementation. .
