Urban expressway, as the main skeleton of the road network, is the aorta between urban regions and urban external traffic communication, but also bears the commuter channel. It makes a large amount of traffic flow into the expressway, resulting the congestion in the expressway in many big cities, including Beijing. Taking the Beijing southwest third ring expressway for example, a simulation model was built using Paramics. The simulation model was pre-evaluated before and after the bus lanes set, and the model was post-evaluated to verify the validity of the model after the bus lanes were implemented, it has important theoretical and practical value.
