Embodiment Construction

[0094] combine figure 1 Describe the bus line combination service method based on Dazhan Express of the present invention, including the following steps:

[0095] Step 1: According to the survey, Chengdu Bus No. 3 has a large passenger flow, the roads along the route are good, the route mileage is long, and there are many stops. Therefore, it is selected as the research object to optimize the stop selection and departure frequency of express trains of No. 3;

[0096] Step 2: According to the survey, the uplink route of Bus No. 3 is from Jiulidi Bus Station to Chengdong Passenger Transport Center, with a total length of about 18.3 kilometers and 32 stations along the route; the downlink route is from Chengdong Passenger Transport Center to Jiuliti Bus Station, with a total length of about 22.1 kilometers, with 30 stations along the line; the driving speed is about 20km / h, and the whole operation time is about 1.5h; the shifts are evenly dispatched by time intervals, and 27 shi...

Abstract

The invention discloses a combined service method of bus routes based on express buses. The method comprises the following steps that a bus route suitable for express bus and whole-course bus combined services is selected; related data of the selected route is collected; passenger flow data is provided with obtain peak hours OD; a BNL model is used to calculate the possibility that a passenger selects an express bus or a whole-course bus, and peak hours OD of different trip modes are predicted; an express bus stop selection and route combined departure frequency optimizing model is established; a genetic algorithm is used to solve an approximate optimal solution of the model, and an expression bus stop and combined departure frequency scheme is obtained; and the sensitivity is analyzed, and influence of unit time value of passenger, unit price of bus operation cost, bus capacity and passenger flow volume on different cost items and combined departure frequencies is researched. Thus, the trio cost of passengers and the bus operation cost can be reduced, and the bus service level is improved.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, in particular to a bus line combination service optimization method based on Dazhan Express. Background technique [0002] Dazhan Express refers to the dispatching form in which buses only stop at stations with large passenger flow along the line during the process from the starting station to the terminal station, and travel faster than the station. It adopts the combined service mode of the bus line of Dazhan Express and full-time bus, which can be used in vehicles Under the constraint of limited resources, improve the public transport service level and reduce the operating cost of the system. [0003] At present, the bus operation managers in most cities still adopt the scheduling method of "evenly dispatching shifts and stopping at stations". With the growth of residents' travel volume, more and more bus passenger flows have great time and space imbalances. The traditional stop-stop...
