This paper studies cooperative signal strategies for Beijing expressway ramping control. Particularly, the distance between on-ramp and off-ramp ranges from 100m to 1000m. Four signal control strategies are proposed and tested under 3 kinds of traffic flow states and 38 kinds of road network structures in VISSIM. Results indicate that the cooperative signal control is an effective way to enhance road capacity and alleviate congestions in urban expressway. Moreover, the control efficiencies in different traffic scenarios are discussed, too.
