摘要
设计了既能体现道路网交通特性,又能综合考虑道路网服务水平、交通的环境影响等隐含因素的城市道路网容量数学模型。以平衡配流算法为基础,设计了模型的求解算法,该算法能快速求解大规模道路网络的容量计算问题,并给出提高道路网容量的方向。
A new mathematic model for urban road network capacity was designed, which both incarnated the transportation characteristics of road network and synthetically considered the service level of road network, traffic affection of environment, and so on. Based on equilibrium assignment algorithm, an algorithm for the model was designed, which could quickly solve the network capacity problem for large road network and gave the direction to the improvement of road capacity.
