Pedestrian flow traffic simulation considering automatic driving vehicle interference under network traffic

Abstract

The invention relates to a two-way pedestrian flow traffic simulation method under the condition that automatic driving vehicles and pedestrians have the same right of way under the condition of signal control intersections and intelligent network connection traffic. The method comprises the following steps: step 1, determining a general rule for pedestrians to cross a road when there is interference of a networked automatic driving vehicle, step 2, determining basic information of a scene in simulation, step 3, selecting and judging a cellular position, step 4, updating a pheromone model, and step 5, judging the number of cycles. The step 3 comprises the steps of 3.1, judging the cellular position where the pedestrian is located, 3.2, judging whether a vehicle exists in front or not and judging the state of the cellular in front or not, and 3.3, selecting the cellular position of the next time step. The step 4 is divided into a step 4.1 of updating a model of a cellular pheromone occupied by a vehicle, a step 4.2 of updating a model of a cellular pheromone occupied by a right pedestrian, a step 4.3 of updating a model of a cellular pheromone occupied by a left pedestrian, and a step 4.4 of updating a model of a null cellular pheromone.

Description

technical field [0001] The invention relates to the field of pedestrian flow simulation analysis when self-driving vehicles and pedestrians have the same right of way and no collision under the background of intelligent networked traffic, and relates to a two-way pedestrian control signal control intersection based on cellular automata theory The simulation model and simulation method of the circulation situation provide a theoretical basis for the development of intelligent transportation and vehicle-road coordination. Background technique [0002] With the rapid development of my country's social economy and intelligent transportation, the number of intelligent networked self-driving vehicles in my country has grown rapidly, the number of self-driving vehicles has increased year by year, and the travel volume of residents has continued to increase, resulting in increasing traffic pressure. Especially in the most typical scenario in the simulation analysis of pedestrian tra...
