Embodiment 1

[0103] figure 2 Given a station network consisting of 9 stations, 12 sections, and 24 directed road sections. The 24 road sections in the network are all 5km in length, and the driving speed of buses is 30km / h. The starting and ending demand of passengers between each station is listed in Table 1. The proportion of passengers who are willing to transfer to their destination is 0.05. Passengers’ in-vehicle time is worth 30 (yuan / person·h), passengers who are unwilling to transfer are worth 50 (yuan / person·h), and passengers who are willing to transfer are worth 70 (yuan / person·h). The vehicle capacity is 70 (person / vehicle); the time for each stop is 0.02h. The operating cost of passenger cars mainly includes fuel consumption, tolls, staff wages, etc., plus tire wear costs, personnel costs, business operation and office costs, etc., equivalent to the total unit operating cost of 30 (yuan / vehicle km). The length of bus lines is limited between 7km-15km.

Embodiment 2

[0115] Such as Figure 7 As shown, a large-scale site network is given, with 65 points, the length of each road section is shown in Table 3, and the demand between each OD pair is shown in Table 4. The speed of the bus is 20km / h. The starting and ending demand of passengers between each station is shown in Table 4. The proportion of passengers who are willing to transfer to their destination is 0.05. Passengers’ in-car time is worth 30 (yuan / person*hour), passengers who don’t want to transfer are worth 35(yuan / person*hour), and passengers who are willing to transfer are worth 50(yuan / person*hour) . The vehicle capacity is 70 (person / vehicle); the time for each stop is 0.02h. The operating cost of a passenger car mainly includes fuel consumption, tolls, staff wages, etc., among which the fuel cost is 1.93 yuan per vehicle per kilometer, plus tire wear costs, personnel costs, business operation and office expenses, etc., equivalent to a total unit operating cost of 30 yuan ...

Abstract

The invention discloses a design method for a conventional urban public transit network. The method includes the steps that a known urban road network is simplified; then, a design model of the conventional urban public transit network is established with the departure frequency as a variable, the minimum passenger and operator cost as an object function and the minimum departure frequency, the vehicle capacity and other limiting conditions as constraints; finally, the optimal public transit network design and the corresponding departure frequency with the minimum total cost can be obtained by adopting a simulated annealing algorithm for solving. The dual purposes of public transit route design and operation dispatching are achieved in a one-time networking mode, route adjustment is performed based on an obtained optimized network, and therefore the public transit network is more reasonable in design, high in quality and more stable in structure and has higher practicability.

Description

technical field [0001] The invention relates to the field of public transportation, in particular to a method for designing urban conventional public transportation network. Background technique [0002] Public transportation is beneficial to reduce air pollution, save energy, alleviate urban traffic congestion, and at the same time maintain social equity, so it is largely regarded as a viable option for realizing sustainable transportation in large and medium-sized cities. An important part of the transportation system. It can be seen that it is of great practical significance to study the design of urban bus network and determine the corresponding departure frequency. The bus route network design (TRNDP) includes two aspects: route layout and related departure frequency design. At present, in the analysis and optimization research of TRNDP, most of the models lack the description of passenger transfer behavior, or study passenger transfer behavior on a designated simple ...
