Coordinated Control of Arterial Road Signals Based on Synchro

To alleviate the traffic congestion at road intersections, based on the theory of coordinated control of trunk signals, the timing scheme of arterial traffic signals is optimized. First, we take Gao Feng Road in Bei Chen District of Tianjin as the research object and investigate the current situation of each intersection. Then, based on the Webster calculation signal period model, the phase and period of the signal are optimized by using synchro. Finally, taking vehicle travel time, total stops, delay, and exhaust emissions as performance evaluation indicators, through simulation and comparison with the current situation, it can be concluded that after optimization, the travel time is reduced by 27.78%, the total stops are reduced by 20.21%, and the delay is reduced by 50.00%. Finally, it can be proved that the optimized signal timing can alleviate traffic congestion and reduce pollution and exhaust emissions to a certain extent.
