Modeling Capacity of Road Network Based on Level of Service of Network

Urban road traffic is the foundation of the existence and development of urban society, therefore the calculation of the capacity of road network is an urgent problem. Based on the bi-level programming model of the road network capacity, the concept of the level of network service is introduced. Considering the impact of network service level on the whole network, this paper has constructed a network capacity calculation model based on level of service of network, and solved it using a kind of hybrid optimization algorithm combined genetic algorithm and simulate annealing (GASA). Ultimately, a simple network has been provided to prove the model as well as the algorithm.
