Hierarchical planning-based urban conventional bus line network designing method

Abstract

The invention discloses a hierarchical planning-based urban conventional bus line network designing method. Hierarchical division is carried out on the line network according to a passenger travel mode, and according to a hierarchical planning result, optional lines in each hierarchy are searched sequentially, and demand allocation is carried out; with a demand allocation structure as a basis, an urban conventional bus line network designing model with a departure frequency as a variable, with the minimization of the cost of the passenger and an operator as an objective function and with restrictive conditions such as a line length, the departure frequency, a transport capability and a line number as constraints is built; and a simulated annealing algorithm is adopted to solve the model, the line network structure and the line departure frequency can be determined at the same time finally, and one-time networking of the hierarchical planning-based bus line network designing model is realized. Traffic zones can be corresponding to multiple departure or arrival sites, which is more consistent with the actual setting condition of sites around the traffic zones, and the calculation result of the model is stable.

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 based on hierarchical planning. Background technique [0002] Public transportation network design is a key part of public transportation development planning, which plays a decisive role in residents' daily life, work travel and even the healthy development of urban economy and society. Conventional public transport is an important part of urban public transport system, so the research on the design of urban conventional public transport network has important practical significance. The design of urban conventional bus network mainly includes the determination of bus line structure and the calculation of line departure frequency. In previous studies on the design of the bus network, a traffic area was simply associated with a single station, which did not match the actual setting of the surrounding stat...

AI Technical Summary

Problems solved by technology

In previous studies on the design of the bus network, a traffic area was simply associated with a single station, which did not match the actual setting of the surrounding stations of the traffic area, which may lead to large errors; the existing domestic concept of "hierarchical planning" lacks correspondence to it A method that can determine bus line structure and departure frequency at the same time; and the existing "level planning" network design model lacks the description of passenger transfer behavior; in addition, the station repetition rate on the line in the existing model solution results is relatively low High, and it is impossible to determine the line network structure and departure frequency synchronously
