Abstract
The freeway takes large parts of city's traffic flow.Good traffic managements and control strategies can ease traffic congestion effectively.This paper uses Visual Basic to develop a simulation program based on macroscopic dynamic network model METANET and ALINEA control model.Then the program is used to simulate a network with two origins and two destinations.The simulation results show that speed of freeway adds about 10 km/h and the capacity of freeway with ALINEA control adds about 150 veh/h.The ALINEA control can relieve traffic congestion effectively.
