Abstract:

Infrastructure construction mainly including road and rail can temporarily relieve the contradictions between traffic supply and demand. But there is un-sustainability, because capital and time is limit. So the key point of managing traffic congestion is how to allocate limited traffic resources. In this paper, basing on an integrated transport model, a traffic system capacity optimization method is proposed as a breakthrough of the right of way for the bus. This method proposes the definition of transportation system person capacity. It builds the criteria to measure comfort and controllability. It establishes hierarchical bus lane layout method. It dynamically adjusts road resources between bus and car to protect the right of way of ground bus. It balances the travel speed between car and bus. It transforms personal best into system optimization. It is a new path to implement transit priority. In Guangzhou, capacity analysis technique is applied to the actual road network, and resource allocation scheme is proposed based on bus lane scheme. It guides the development of Guangzhou city traffic.

Key words: urban traffic, transport system capacity, transit priority to right of way, road resource allocation, travel time
