Duncan,British Columbia,Canada

Summary Information

For the past year a real-time adaptive traffic signal control system developed by the British Columbia Ministry of Transportation and Highways in Canada has cut traffic delays significantly. Since mid-1995, urban corridor traffic signal systems on the provincial highways have produced an average savings of more than 25 percent in traffic delays. In April, 1996, the first dynamic system was implemented on the Trans-Canada Highway in Duncan, British Columbia, Canada. Initial analysis shows that an additional reduction of 15 percent in traffic delays has been achieved during the peak traffic periods compared with the results achieved from the previous fine designed static control. Traffic flows through Duncan improved during the evening peak of 1,200 vehicles per hour.
