Research on the Evaluation of Urban Skeleton Road Network and External Freeway Network Fusion

The reasonable connection between the external freeway network and the urban road network can alleviate the traffic pressure in the city. The fusion evaluation between the external freeway network and the urban road network are studied. Firstly, considering from three aspects of the facilities and the service performance and the connection point operation quality, the evaluation indicator system of two networks is established. Then, based on the cloud model and fuzzy comprehensive evaluation method, the fusion evaluation method based on cloud model - fuzzy comprehensive evaluation method of two networks is established, and the fusion evaluation process is determined. Finally, the effectiveness and scientific of the fusion evaluation method are verified by a case analysis of the skeleton road network and the external freeway of Changsha city.
