山区小城市路网承载力评估模型及算法OA

In order to effectively evaluate the supply capacity of the road network in small cities in mountainous areas and reveal the impact of road traffic characteristics such as low connectivity and severe interference between vehicles and non vehicles on its road network carrying capacity,this paper defines the road network carrying capacity of small cities in mountainous areas,establishes a two-level programming model,and proposes a variable step iterative optimization algorithm to achieve approximate solution of the model.The example results show that the model and algorithm have high practicality and effectiveness.
