| In recent decades,in order to eliminate the negative impact of urban congestion,many cities have built their own subway transportation systems.At the same time,under the application of TOD mode,the connection between subway station and urban commercial area is becoming closer and closer.Commercial central subway station has become one of the most important public spaces in the city.Through the investigation,it is found that there are crowding and streamline crossing in the internal space of many commercial central subway stations,which leads to the low level of traffic efficiency in the station.The existing research on the optimization design of the internal space of the subway station lacks the research on the special station space.It mostly cuts into the ordinary station,which is not targeted,and cannot get accurate optimization feedback in reality.At present,there are few studies on the space traffic efficiency in the station,and a complete influencing factor composition and evaluation system has not been formed.Through the summary of research status,relevant theories and case studies,combined with practical investigation and integrated analysis,this paper refines the influencing factors of internal space traffic efficiency of commercial central subway station from three levels:passenger traffic characteristics,space environment factors and equipment and facilities factors,involving the basic attributes and behavior characteristics of passengers,the spatial scale,proportion,spatial interface,and the service capacity of traffic facilities in the station The location and quantity of service facilities,and puts forward the quantitative evaluation method of traffic efficiency.After combing the commercial center subway station in Chengdu,Chunxi Road subway station is finally selected as a case station for in-depth research,which is analyzed by qualitative and quantitative methods such as field investigation,questionnaire survey,interview and software simulation,so as to quantitatively evaluate the traffic efficiency of the space in the station and summarize the existing problems of the space,Then it puts forward the Countermeasures for the internal space optimization design of commercial central subway station from the perspective of traffic efficiency.Finally,through the simulation of the optimization scheme,the effectiveness of the optimization scheme and the optimization scheme of the internal space are compared,and the optimization scheme is tested again.The research of this paper aims to improve the traffic efficiency of the internal space of the existing commercial central subway station,provide more systematic and reasonable optimization guidance from the perspective of architectural design,and provide reference for the construction of similar buildings in the future. |
