Problems solved by technology

[0003] With the continuous expansion of the city scale, the bus lines form different levels according to the service function and passenger flow characteristics. If the bus lines of different levels are optimized at the same time, the efficiency will inevitably be low, and the priority will be unclear.

Embodiment

[0145] Select a certain city as an example analysis, in order to verify and evaluate the method of the present invention. A certain city is a small and medium-sized city with a population of about 300,000. The city's traffic network consists of 22 traffic districts, 278 road nodes and 482 road sections. In order to effectively understand residents' travel wishes and add necessary routes to the set of alternative routes, a total of 29,500 questionnaires were distributed and collected (the sampling rate was about 10%). And based on the above survey, it is concluded that the city's travel demand is 209,563 person-times / day.

[0146] According to the urban scale of the city, the transportation mode adopted by the skeleton line network is tram, which should meet the constraints of safety conditions, road width conditions and line length conditions; the transportation mode adopted by the main line network is Bus Rapid Transit (BRT) and conventional buses, should be analyzed from t...

Abstract

The invention discloses a public transit network planning method based on multiple levels and multiple modes. The public transit network planning method comprises the following steps that basic data are collected, communication and transportation modes are determined according to the city size, and influence factors needed by public transit network planning are analyzed; a public transit network planning model is built, and relevant parameters are set; the public transit network planning model is solved; a planning result is output. The public transit network planning method can better adapt to passenger flow features and setting features of different public transit networks, thereby being better in effect; the public transit network planning method is superior to existing methods on the evaluation index aspects of the nonstop passenger flow volume, the passenger demand ratio, the total travel time and the like.

Description

technical field [0001] The invention belongs to the field of transportation, in particular to a multi-level and multi-mode based bus line network planning method. Background technique [0002] At present, urban traffic congestion has become a serious social problem, and the annual economic loss accounts for about 5% to 8% of my country's GDP. In addition, traffic pollution, especially motor vehicle exhaust pollution, has become a serious challenge to the urban environment. At the same time, transportation energy consumption is huge, which directly affects the protection and improvement of the national economy and people's livelihood, and restricts the implementation of the national energy conservation, emission reduction and sustainable development strategy. Therefore, carrying out research on the planning and construction of urban high-efficiency public transport systems will provide important technical support for prioritizing the development of public transport, improvin...
