Problems solved by technology

However, passengers face a contradiction between travel cost and service quality in conventional public transport systems
Although buses and subway light rail can meet the travel needs of a large number of passengers and travel costs are low, it is also difficult to achieve a high service level due to the constraints of fixed dispatching arrangements and limited scope of infrastructure construction, and it is also difficult to radiate the service scope to the suburbs and even neighboring cities
Although taxis are more flexible and can provide door-to-door travel services, the passenger-sharing mode is not widely used, so the travel demand that can be served is limited and the cost is high

Embodiment Construction

[0076]The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0077]For such asfigure 2 As shown in the network topology structure between venues and venues, the given event schedule is asFigure 6 ,Figure 7As shown, the demand scale of the passenger travel chain on a single match day is set according to the event schedule. For passengers who plan to watch multiple events on a single game day and choose the travel chain-oriented demand response bus "one ticket" service proposed by the present invention, the travel chain-oriented demand response bus service mode and optimization method provided by the embodiments of the present invention ,Such asfigure 1 As shown, it specifically includes the following steps:

[0078]S1. Develop a "one ticket" service model for public transport in response to the needs of the travel chain.

[0079]The travel chain refers to a travel behavior in which pas...

Abstract

The invention discloses a trip chain-oriented demand response bus service mode and optimization method. The method comprises the following steps: formulating a trip chain-oriented demand response bus'one ticket 'service mode; generating a constraint set and an objective function of a trip chain-oriented demand response bus 'one-ticket' service operation cost according to the pick-up and drop-off station network topology, the passenger trip chain information and the bus information; according to the constraint set and the target function, establishing a mixed integer linear programming model for travel chain-oriented demand response bus one-ticket service operation vehicle path optimization; and solving the mixed integer linear programming model, and obtaining an optimized service vehicle running path scheme through an effective inequality and a genetic algorithm based on an optimal time difference insertion method. According to the invention, the high-level customized public transportservice is provided, and the complexity that passengers need to select a travel chain combination scheme from a plurality of conventional fixed public transport modes is also reduced.

Description

Technical field[0001]The invention relates to the field of urban public transportation planning, in particular to a demand response bus service mode and an optimization method for the travel chain.Background technique[0002]With the rapid advancement of global urbanization, the demand for urban transportation and travel has grown rapidly, and personal travel plans have become more personalized and diversified. In large cities with high population density and high intensity of land use and development, only urban transportation led by public transportation can achieve sustainable development. However, passengers face the contradiction between travel cost and service quality in conventional public transportation systems. Although buses and subway light rail can meet the travel needs of a large number of passengers and have low travel costs, they are also difficult to achieve a high level of service due to fixed scheduling arrangements and limited infrastructure construction, and it is ...
