Embodiment

[0056] The simulation system is based on the Net Logo platform for case studies. The three-lane scenario of urban arterial roads is selected for research. In this implementation example, a two-way six-lane urban arterial road with a central divider is designed according to the specifications. The width of the lanes is set at 3.5m, and no slopes and flat curves are set. In the simulation, the vehicle is designed according to the width of 1.8m and the length of 4.5m.

[0057] Use the built-in language function of Net Logo to write the rule algorithm and the vehicle-driver agent architecture, and it can run normally and interactively through debugging. The calibration of the main parameters of the driver-vehicle agent is shown in Table 1:

Abstract

The invention aims to provide a road mixed traffic flow simulation system based on a multi-agent system, a heterogeneous driver traffic simulation system is constructed by using a Net Logo platform, the simulation system comprises a driver-vehicle agent and a road environment agent, the road environment agent is used as a carrier. According to the method, the traffic scene is simulated, and information interaction with a driver-vehicle intelligent agent is carried out, so that behaviors and interaction of the driver in the traffic scene are simulated, generation and dissipation of congestion and collision are simulated, and the traffic scene under a complex condition is formed.

Description

technical field [0001] The invention belongs to the technical field of traffic control, in particular to a road mixed traffic flow simulation system based on a multi-agent system. Background technique [0002] The current multi-agent-based traffic flow simulation method is mainly based on data-driven and agent-based artificial intelligence algorithms to find the optimal solution. Previous research has also used game theory models, cellular automata modeling, and multi-agent simulation technology to make Researchers were able to avoid using overly complex mathematical equations to express the nonlinear relationship of vehicle state changes in the model, and thus focus on the strain of individual behavior to reflect the heterogeneity of driving performance. [0003] However, in reality, drivers cannot quickly and accurately calculate their own optimal behavior. People often make mistakes due to various reasons, such as experience, psychological state, and physiological state. ...
