Vehicle motion simulation analysis method in urban traffic scene

Abstract

The invention discloses a vehicle motion simulation analysis method in an urban traffic scene. The intelligent following model based on the safety distance is improved, the characteristics that the vehicle safety distance is small and the following vehicle starts to follow the front vehicle to accelerate in an urban traffic scene can be better simulated by adding an acceleration adjustment item toa vehicle acceleration formula, and the applicability of the model is improved. A double-lane model based on acceleration analysis is improved, the lane changing process of a vehicle is evaluated tojudge whether lane changing behaviors can be executed or not, and the rationality of the proposed model is verified through experiments.

Description

technical field [0001] The invention belongs to the field of computer graphics, relates to the simulation of group movement, in particular to a method for simulating and analyzing vehicle movement in urban traffic scenes. Background technique [0002] In recent years, with the rapid development of urban traffic, the traffic volume has continued to increase, and problems such as traffic jams and vehicle accidents have become more and more obvious. These problems have seriously hindered the development of urban economy and society, and reduced people's living standards and quality of life. At present, modern computer simulation technology is used to model and simulate the complex dynamic traffic system of the city, especially the simulation of vehicle movement to study how to plan scientifically and rationally for urban traffic, reduce traffic accidents and congestion, and ensure the quality of travel. attracted people's attention. [0003] At present, most of the research on...

Problems solved by technology

Treiber et al. summarized an intelligent car-following model based on a safe distance. This model is suitable for simulating vehicle movement on the expressway. It is necessary to maintain a large acceleration when driving, and the expected effect cannot be achieved when using this model to simulate vehicle motion

In response to this problem, Lei Peng considered using acceleration control items and deceleration control items to solve the problem of too slow acceleration of the vehicle behind when the vehicle starts, but this method is cumbersome, and the acceleration of the vehicle behind changes greatly when the vehicle changes lanes at low speed. Does not conform to the motion behavior of vehicles in urban traffic scenes
