Pedestrian behavior simulation method in microscopic traffic simulation

Abstract

The invention relates to a pedestrian behavior simulation method in microscopic traffic simulation, which comprises the following steps of: firstly, using an agent technology and a high level architecture / run-time infrastructure to build a traffic environment model and various behavior atom model sets; secondly, building a managing and managed logic relationship between traffic entity agents and road sections and between the traffic entity agents and the crossings of the road sections; then, through the communication between pedestrian agents and the traffic environment, acquiring traffic environment information, conducting knowledge filtration to the information, recombining the information into internal conceptual representation, conducting reasoning to the environment and self-desires through a belief-desire-intention technology and obtaining a further behavior plan required to be executed by pedestrians; and finally, executing the plan and forming a simulation step size to realize the effective simulation of pedestrian behaviors. The method can accelerate the generation of the behavior plan of the simulation system and the reasoned pedestrian characteristics are more fit to the simulation of the pedestrian behaviors.

Description

technical field [0001] The invention relates to a method in the field of computer application technology, in particular to a pedestrian behavior simulation method in microscopic traffic simulation. Background technique [0002] With the rapid increase in the complexity of urban traffic, a large amount of capital is often required to solve real traffic problems. At the same time, there are many unsafe factors in the operation in the actual environment, which makes it more difficult or even unfeasible to find an optimal solution. At this time, the application of computer technology for traffic simulation has become an effective technical means to solve traffic problems. It can not only reproduce the technology of temporal and spatial changes in traffic flow, provide technical basis for traffic road design and planning, but also compare and evaluate various parameters, and provide important information for traffic planning, traffic command and emergency treatment of traffic pol...

TEMS IMULAT 10N) "Development and Research Status of Traffic Simulation" published on pages 1179 to 1187, No. 8, 2003, mentioned that various typical simulation methods at home and abroad basically belong to the macroscopic or microscopic aspects of the traffic environment. One side, a certain part of the simulation, such as CORS IM (microcosmic simulation system developed by the US Federal Highway Administration) and PARAMICS (simulation system for the road network developed in Scotland), its shortcoming is that it cannot be used for emergency evacuation and evacuation. Traffic command and dispatch in large gatherings provides an effective basis for predicting pedestrian behavior
