Improvement of Traffic Flow on Highway Network with Area Control Scheme under Ealthquake Environment

Abstract

Crisis management for highway network is very important immediate after a strong earthquake. This paper presents the area control scheme for traffic on the cross sectional line(screenline) of highway network in the affected area. The framework and analyzing model including traffic generation/attraction, traffic distribution, traffic assignment and the network evaluation are developed. For several types of traffic control, their effbcts are studied for various OD flow patterns. The result indicates the proposed traffic control is very effective depending on the control site and the level of the control.
