Introduction

Traffic accidents and congestion are a major concern for urban planners and transportation engineers. The increasing complexity of traffic systems demands innovative solutions that can effectively manage and mitigate the impact of accidents on traffic flow. Traditional traffic management strategies often focus on individual objectives, such as minimizing travel time or reducing congestion. However, these approaches may not consider the complex interactions between different traffic components, leading to suboptimal solutions. In recent years, there has been a growing interest in developing multi-objective collaborative optimization and control strategies that can address the complexities of traffic systems.

Multi-Objective Collaborative Optimization Framework

A multi-objective collaborative optimization framework is a decision-making approach that considers multiple objectives and constraints simultaneously. In the context of traffic accident congestion, the framework aims to optimize traffic flow while minimizing the impact of accidents on traffic systems. The proposed framework consists of three main components:

Dynamic Decision-Making with Multi-Intelligent Deep Reinforcement Learning (MADRL): This component utilizes MADRL to make dynamic decisions about traffic signal control, lane management, and incident response. MADRL is a type of deep reinforcement learning that integrates multiple intelligent agents to learn from experience and adapt to changing traffic conditions.
Real-time Feedback Regulation: This component uses real-time feedback from traffic sensors and cameras to regulate traffic flow and respond to accidents. The feedback is used to adjust traffic signal control, lane management, and incident response strategies in real-time.
Digital Twins: This component utilizes digital twins to assess the benefits of different control strategies and optimize traffic flow. Digital twins are virtual replicas of physical systems that can be used to simulate and analyze different scenarios.

Benefits of Multi-Objective Collaborative Optimization Framework

The proposed multi-objective collaborative optimization framework offers several benefits, including:

Enhanced safety: The framework enhances safety by responding to accidents in real-time and adjusting traffic signal control and lane management strategies accordingly.
Increased efficiency: The framework increases efficiency by optimizing traffic signal control, lane management, and incident response strategies.

Real-Time Feedback Regulation and Benefit Assessment

Real-time feedback regulation is a critical component of the proposed framework. It uses real-time feedback from traffic sensors and cameras to regulate traffic flow and respond to accidents. The feedback is used to adjust traffic signal control, lane management, and incident response strategies in real-time. The benefits of real-time feedback regulation include:

Improved traffic flow: Real-time feedback regulation optimizes traffic flow by adjusting traffic signal control and lane management strategies in real-time.
