Research of Variable Lane Control Method in the Emergency Evacuation Area

摘要

When unexpected disasters are coming, tens of thousands of people lost their lives because of no emergency aid caused by traffic jam. We need to build an emergency planning based on traffic evacuation. This paper proposes a method of variable lane control based on emergency evacuation area, establishes a bi-level programming model and designs solution algorithm based on harmony search to find the optimal solution quickly. After getting the optimal solution, we build the simulation experiment to verify the feasibility and effectiveness of proposed method according to the comparison of the saturation degree and the total travel time of system.
