This study introduces a congestion coefficient feedback strategy to optimize urban traffic flow. Simulation results show it effectively guides drivers and improves traffic conditions compared to other methods.

Area of Science:

  • Transportation Science
  • Socioeconomic Systems Analysis
  • Information Feedback Systems

Background:

  • Optimal information feedback is crucial for resource optimization in socioeconomic systems, including traffic.
  • Real-time traffic information and route guidance can significantly improve urban traffic conditions.
  • Existing feedback strategies like travel time and mean velocity have limitations.

Purpose of the Study:

  • To introduce and evaluate a novel congestion coefficient feedback strategy for urban traffic management.
  • To assess the effectiveness of this strategy in controlling spatial traffic distribution.
  • To compare the proposed strategy against traditional feedback methods.

Main Methods:

  • Development of a congestion coefficient feedback strategy.
