Empirical Analysis Of Urban Microcirculation Bus Demand Characteristics And Research On Route Design Method

The micro-circulation bus plays an important role in solving the problems of low utilization rate of urban branch roads,difficult travel of residents in short distances,and weak local bus services.Micro-circulation bus lines have been opened in several cities in China,but some of the lines have failed to connect with the surrounding passenger demand areas,resulting in low passenger traffic and poor operational results.Therefore,only by fully understanding the micro-circulation bus operation characteristics and demand characteristics,accurately identifying the line service area,and combining the short-distance travel demand of passengers to lay out the line,can better play the micro-circulation bus function.This paper combines the status quo of micro-circulation bus operation services opened in Shenzhen,summarizes the characteristics of micro-circulation bus service,function positioning and operation mode,and analyzes the micro-circulation bus demand group and passenger outflow destinations through the data and survey data provided by the bus big data analysis platform.Demand characteristics such as passenger time and space distribution and demand space area and passenger travel characteristics,and analysis of the factors affecting travel demand.Based on the calculation index of site and line reachability,the big data bus service capability analysis method is used to identify the bus service weak area and short-distance travel,and then the micro-circulation bus line layout area is defined,and the passenger flow calculation model based on the original unit method is established.Based on the travel time cost of passengers,the calculation method of the optimal micro-circulation bus stop distance is given.The theoretical calculation value has a high degree of fit with the optimal station spacing of micro-circulation bus operated by Shenzhen City,and the best is determined by this station spacing.The service radius is one of the constraints.The site layout model with the minimum distance from the micro-circulation bus travel in the traffic cell to the total distance of the station is established and solved by MATLAB.Considering the form of circular connection microcirculation bus,the characteristics of the line layout model contrast evolution algorithm and the traditional algorithm are established,the paper chooses the traditional algorithm to solve the problem.Finally,taking Henggang Village in Longgang District of Shenzhen as an example,using the microcirculation bus line layout method proposed in this paper,a micro-circulation bus line was set up,which proved the practicability of the method.
