Aided Plan and Optimization of Road Routing in Cooperative Multi-Transportation System

For multi-transportation system in ITS (Intelligent Traffic System), aided plan and optimization of road routing are important problems. Traffic network is a key unit in cooperative multi-transportation system of intelligent traffic and a basis of the municipal infrastructure construction. In cooperative multi-transportation network aided plan, two problems are studied, one is how to plan traffic road routing in order to cover the social districts in the main cities; the other is how to choice the optimize routing from the start point to the end. For the first one, an aided plan algorithm for multi-transportation road routing is studied and taken forward. The other one is an algorithm for optimizing road routing, which put forward an optimization routing from start position to end position in traffic network.
