Research on Emergency Evacuation Time under Different Road Network Form

Abstract

This paper studies the emergency evacuation time of vehicles in three different forms of road traffic networks, and finds out which traffic network is more suitable for emergency evacuation of road traffic network. Based on the method of emergency evacuation path optimization of road congestion degree, this paper simulates the emergency evacuation time of a certain number of vehicles in three different road network forms by MATLAB simulation. The results show that the total evacuation time of the 2000 vehicles in the ring radial road traffic network is the shortest, followed by a square grid road traffic network and freestyle road traffic network. Compared with the square grid road traffic network and the freestyle road traffic network, the total evacuation time of the ring radial road traffic network respectively is reduced by 7.7% and 45.7%. It can provide some reference for the future planning and construction of the road network around the large public parking lot. The innovation of this paper examines the emergency evacuation time of three different road traffic networks.
