Problems solved by technology

[0009] However, all the above-mentioned studies are based on the ideal traffic environment, and the simulation of real traffic scenes still needs to be studied. Some traffic simulation tools (such as VisSim) have involved the micro-simulation of human-vehicle interaction, but their methods only set the mobile priority, oversimplifies the problem and does not match the real situation

Embodiment Construction

[0069] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.

[0070] In order to simulate the interactive behavior of vehicles and pedestrians, the present invention firstly inputs the position information between the mixed flow of pedestrians and vehicles, obtains the distance between individual pedestrians and vehicles and the width of the road, calculates the predicted passage time of pedestrians and vehicles, and compares pedestrian Decide whether to cross the road.

[0071] Such as figure 1 As shown, the vehicle and pedestrian interactive simulation method for the traffic mixed flow model of the present embodiment, the traffic mixed flow model includes road, vehicle flow and pedestrian flow, the original control model that each vehicle carries is the IDM model, and pedestrians carry their...

Abstract

The invention discloses a vehicle-pedestrian interactive simulation method for a traffic mixed flow model. For simulating any pedestrian crossing the road, the following steps are included: obtaining the coordinates of the pedestrian to cross, and obtaining the distance from the pedestrian in the traffic flow close to the pedestrian. The coordinates of the pedestrian's nearest vehicle; according to the obtained coordinates of the pedestrian and the vehicle, calculate the time for the pedestrian to cross the road and the time for the vehicle to cross the pedestrian; compare the time for the pedestrian to cross the road and the time for the vehicle to cross the pedestrian, and perform different controls according to the results ; Then add the driving force feedback item to the original driving force item to drive the pedestrian forward or stop; Add the acceleration feedback item to the original acceleration item to drive the vehicle forward; Lack of authenticity and human-vehicle interaction in simulation.

Description

technical field [0001] The invention relates to the technical field of virtual simulation, in particular to a vehicle-pedestrian interaction simulation method for a traffic mixed flow model. Background technique [0002] In recent years, the simulation of road traffic has received more and more attention. In traffic systems, vehicles and pedestrians are two very important objects. In the real world, vehicles and pedestrians are inextricably linked, and the interaction between the two is very complex. Simulation of vehicle-pedestrian interactions in traffic systems contributes to traffic safety and future development in urban environments. In addition, the simulation of mixed traffic flow can more realistically reflect the urban environment. [0003] Currently in the field of computer graphics, the behavior of vehicles and pedestrians is always separated into two parts. There is a large body of literature on modeling and simulating vehicle flows and pedestrian groups usin...
