Finally, the congestion levels of the traffic lanes of each gap are re-evaluated at fixed time intervals, and when changes in the relevant data of a certain road section are detected, resulting in a change in the congestion level, the updated congestion information is immediately transmitted to the central control module, so that the central control module can respond in time and adjust the corresponding management strategy.
