Abstract :
Because the distance between on-ramp and off-ramp ranges from 100m to 1000m in Beijing expressways, traffic congestions generated at these "bottlenecks" had been observed frequently. In this paper, on-ramp signal control strategies are tested under 3 kinds of traffic flow states and 19 kinds of road network structures in VISSIM. The control efficiencies in different traffic scenarios are discussed, results indicate that only applying on-ramp signal control is an ineffectiveness way to enhance road capacity.
