Adaptability Evaluation Of Urban External Passageway And Urban Transportation Hub

Transportation is an important service industry indispensable to national economic development,and transportation corridors and hubs are important components of the transportation system,with transportation corridors being a collection of different traffic routes and means of transportation,and hubs being the intersection of different traffic routes in the transportation system.In the existing research,transport channels and hubs are planned separately,ignoring the symbiotic relationship between transport channels and hubs and not considering the integrated planning of both.To address this problem,this paper analyzes the integration mechanism of transportation corridors and transportation hubs,constructs an index system for evaluating the adaptability of transportation corridors and transportation hubs,and applies the index system to Chongqing North Station to evaluate the adaptability of this system,and then gives an optimization approach based on the evaluation results.Firstly,the paper takes the Yangtze River Delta city cluster as a case study to analyze the impact of the construction of transportation corridors and hubs on the city cluster,which is reflected in four levels: travel time,urban spatial pattern,economy and urban industrial structure.At the macro level,the connotation of the mutual influence of city,hub and transportation channel planning is analyzed;at the meso level,the connotation of the role of each functional area in the hub is elaborated,and the theory of spatial syntax in architecture is applied;at the micro level,the connotation of the integrated At the micro level,the factors influencing the decision of integrated planning such as the location of transportation hub,the scale of integrated transportation hub,the structure of transportation modes,the main control points of intra-city transportation lines and the level of transportation lines are specifically analyzed.The second part is the analysis of the transport capacity of the transport corridor and the transport hub,which consists of two parts: first,the analysis of the structure and characteristics of the transport corridor and the transport modes in the hub,and the introduction of the calculation method of the transport capacity of each transport mode in the transport corridor;second,the analysis of the adaptability between the transport capacity of the transport corridor and the distribution capacity of the hub,and the capacity between the transport capacity of the corridor and the transport modes in the hub.The second is the suitability analysis between the transport capacity of the transport corridor and the hub distribution capacity,and the capacity analysis between the transport capacity of the corridor and the transport modes in the hub,and the model formula is given for the suitability of transport capacity.Translated with www.Deep L.com/Translator(free version)Finally,based on the basic theoretical analysis in the previous two chapters,an evaluation index system for the adaptability of the transport corridor and the transport hub is constructed from the perspectives of decision makers and users,and then a fuzzy comprehensive evaluation method is used to evaluate the adaptability of the Chongqing North Station transport hub.
