Embodiment Construction

[0065] The method of the present invention will be described in further detail below in conjunction with the field survey data of a certain bus stop in Nanjing and the accompanying drawings.

[0066] 1. Scenario parameter setting

[0067] The scenario parameters required in steps 1 and 2 of the present invention are set. According to the field investigation, the station is set as a standard two-berth, two-station platform bus station, and is equipped with stop signs and shelters, but not with waiting guardrails; the surrounding land is for residents and scenic spots, and the specific conditions are shown in Table 1. Show.

Abstract

The invention discloses a bus passenger boarding and alighting behavior simulation method based on a social force model, which comprises the steps of shooting a bus passenger flow video, acquiring a boarding and alighting behavior characteristic, performing square net division on a scene, performing simulation setup on an arrival rule of a bus, setting generation, distribution and movement rules of passengers, introducing a neighbor domain searching algorithm to express a passenger stress characteristic by using a vectorial force, introducing a visual field blocking judgment rule to correct a social acting force, and introducing a collision avoidance judgment rule to judge collision possibility in advance. The method introduces a pedestrian flow simulation concept, treats each bus passenger as a micro individual, achieves calculation of passenger boarding and alighting time and evaluation of boarding and alighting efficiency via quantification and modeling of micro behavior parameters of the bus passengers, and provides assistance for effective decision-making assistance bases and optimization of an urban bus trip.

Description

technical field [0001] The invention belongs to the field of traffic behavior microcosmic simulation, and relates to a behavior simulation method for passengers getting on and off the bus. Background technique [0002] As a transportation mode with large capacity, low energy consumption, low emission and high efficiency, public transportation occupies an extremely important position in the urban comprehensive transportation system. However, despite the rapid development of urban public transport in my country in recent years, the current development speed and service level of the urban public transport system cannot serve as an important support for the large-scale travel needs of the city. Bus delays and unpunctual phenomena frequently occur, especially It is more serious during the traffic rush hours, which greatly affects the residents' choice of public transportation. How to reduce bus travel delays, give full play to its traffic efficiency, and increase operating speed ...
