Embodiment Construction

[0186] The research area of ​​the actual case is the Huilongguan community in Beijing, with an area of ​​about 4.8km×2.2km, located in the suburbs of Beijing, such as Figure 7 shown. The area is divided into 264 grid cells, each cell has a side length of 200 meters, and there are 106 nodes in the road network, including 1 station (node ​​0), 55 bus stops (nodes 1-55) and 6 subway stations (nodes 56-61), topological network such as Figure 8 shown.

[0187] In order to measure the travel demand between each grid area and each subway station, the bus IC card data is used to identify the "bus-subway" joint travel chain of each bus stop in the study area during the morning rush hour, and then the station's The demand is allocated to the cells covered by the service area according to a certain proportion, which can be determined by the total travel demand in the current traffic area. Equations (39)-(40) give the calculation of the demand for each grid cell formula.

Abstract

The invention discloses a community public transportation network and departure frequency synchronous optimization method considering regional full coverage for subway connection, and belongs to the field of public transportation network planning. According to the method, a research area is divided into a plurality of grid-shaped cells, minimization of total cost is taken as an optimization target, and a mixed integer optimization model is constructed in consideration of community microcirculation bus network layout and line departure frequency setting. In the solving process, the invention provides a series of constraint conditions based on reality, such as line length constraint, line network total service range constraint, vehicle capacity and motorcade scale constraint. According to the method, a plurality of crossover operators and mutation operators are designed to optimize in the online network scheme population. The invention also provides an adaptive weight adjustment algorithm, and the algorithm can adjust the execution probability of the next-generation operator according to the execution condition of the genetic operator, so as to improve the execution efficiency of thegenetic algorithm.

Description

technical field [0001] The invention belongs to the field of public transportation network planning, and relates to a method for synchronously optimizing the public transportation network and departure frequency of a community connected to a subway considering full coverage of the area. The invention is suitable for optimizing the bus line network in small and medium-scale road network areas. Background technique [0002] With the development of urban transportation, conventional public transport has played an important role in urban passenger transport, but due to the limitation of its vehicle type, it is difficult to play its connection function well in areas with sparse distribution of subway stations (especially in the suburbs), and the community micro Circular buses operate more flexibly in such areas and can provide passengers with more convenient services. During the travel process, passengers may need to transfer multiple times to realize the "bus-subway" hybrid tra...
