Research on an Optimization Model of Highway Network Structure under Regional Traffic Integration Conditions

摘要

This study aimed to optimize network structure under the condition of regional transportation integration to compare and analyze the transportation costs, transportation time, and rate of traffic accidents before regional transportation integration. A network optimization model with the maximum economic benefit as the objective function of the network was set up, which could achieve optimization of the whole highway network under the regional traffic integration condition. Finally, the evaluation of costs-benefit ratio of optimized traffic network was made, and examples are given to demonstrate the regional transportation integration can bring economic benefits.
