| Urban residents’ choice of travel mode constantly changes a city’s traffic indicators,which also reflects the city’s happiness,and affects the city itself and urban planning.In recent years,with the rise of the concept of "low-carbon life,green travel",the development of pedestrian and cycling traffic has attracted more and more attention.As a product of green travel development,sharing bicycles can reflect the urban hot area to a certain extent.The study on the service quality level of the non motorized Lane in this hot area,which is not only the basic research of non-motorized traffic theory in Chengdu,but also is the important basis of road design,ensuring the safety of residents and improving the quality of road traffic service.(1)Based on the combing domestic and foreign research,this paper summarized the development status and hot issues of shared bicycle,and further analyzeds the research status of non-motorized Lane service level model,verified the applicability of typical service level model in China.Based on the geographical location,natural situation,history and culture of Chengdu,analyzed the important basic conditions for the shared bicycle,and analyzed the the overall road layout structure and the development status of non-motor vehicles,which can provide data support for the use of shared bicycle riding data to infer the hot areas of non-motorized lanes of Chengdu.(2)Based on the large background data of individual bicycle positioning by sharing bicycle companies,carried out the point dates of urban roads of Chengdu by using the data grabbing ability of Python.By using the buffer analysis function of ArcGIS,the shared bicycle thermodynamic diagram of Chengdu during the peak travel period was obtained,and the accuracy of popular cycling roads was further obtained.(3)Based on the wishes of travelers,the service quality of popular non-motorized lanes of Chengdu was evaluated by video shooting,questionnaire survey and volunteer rating.Furthermore,the service quality of popular non-motorized lanes such as Wangjiang Road and Kebei Road was evaluated comprehensively from the safety,comfort and cleanliness.(4)Based on the evaluation results of the service level of non-motorized lanes,the optimization and improvement suggestions for the hot non-motorized lanes were put forward from the whole and part respectively,which could be wished to provide a basis for the division of non-motorized lanes resources for Chengdu,improve the utilization rate of urban road resources,and further guide the development of non-motorized traffic and urban traffic structure changes. |
