Study On The Characteristics And Design Of Urban Greenway Crossing Facilities

With the improvement of the city’s convenient travel and space environment requirements,Greenway,as a new urban infrastructure integrating two demands,has effectively supported the modernization of "green livable forest cities" and "friendly green streets".The urban development strategy has received eager attention from urban residents and academic circles at home and abroad in recent years.As the independence of the quality space and the openness of the travel corridor,the greenway requires good continuity in the conflict with the motor vehicle lane.However,there are still many problems in the design of the greenway crossing facilities,and the continuity experience is very poor.Therefore,greenway crossing design has become an engineering issue worthy of attention.Based on the problem of discontinuity in the crossing of the recreational greenway(Guitang River Greenway)and the traffic greenway(Jinxing Road Greenway),this paper designs an SP questionnaire for the use of street crossing facilities.Based on the survey data,the motivation for using the greenway and crossing the street Preliminary use characteristics analysis was performed on facility preferences and facility property requirements.Then the ICLV model of greenway crossing facilities including socio-economic characteristics,design attributes and continuous comfort perception latent variables were established,and compared with the binary logit(BL)model without latent variables.The model parameters were calibrated by Mplus software.Similarities and differences in the use of cross-street facilities for type greenway people.Finally,based on the results of ICLV model analysis of the Jinxing Road Greenway crowd crossing facilities,the greenway facility engineering optimization plan for the calm and quiet design of the intersection of Jinxing Road Greenway and Tongzipo Road was proposed,and the Jinxing Road Greenway and other Optimization suggestions for living street crossing facilities with low traffic volume are given.The research results show that the ICLV-based greenway crossing facility selection behavior model has better fitting and interpretation ability than the traditional BL model.From the parameter analysis results,the commonality and the opposite sex of the use characteristics of the two green road crossing facilities can be obtained.The common feature is that the use characteristics of the greenway crowd crossing facilities are mainly affected by the design attributes and continuous comfort perception latent variables.The crossing comfort facilities with high comfort continuity are more popular,and the design properties,long bypass distance and signal waiting Both time and low level accessibility have a significant negative impact on the cross-street utility of the two greenway users;at higher traffic levels,the possibility of pedestrian bridge selection is significantly improved.The difference is characterized by the fact that the recreational greenway population is more sensitive to the continuous comfort perception of the crossing space,with lower tolerance,higher requirements for the appearance,accessibility and practicability of the crossing facilities;Pay attention to the practical functions of the street facilities,prefer to use safer,more convenient and convenient street crossing facilities,and have higher tolerance to the bypass distance and signal waiting time of the crossing facilities.In general,the differences in the use characteristics of the crossing facilities of the two types of greenway users are consistent with their corresponding greenway functional characteristics.Based on various types of greenway crossing facilities and usage scenarios,this paper uses the ICLV model method to construct a traffic greenway and recreational greenway crossing facility selection behavior model,and explores the characteristics of the use behavior of the greenway pedestrian.It is the role of continuous comfort perception in behavior selection characteristics,and an empirical analysis is carried out.The research enriches the theory of people’s crossing facilities behavior under the greenway scene,and has certain practical significance for the planning,design,decision-making and management of the greenway crossing facilities.
