Development of the Status Map for Integration of Ramp Metering and Information Provision

Abstract

On urban expressways, ramp metering and information provision conducted by road administrators have significant effects on mitigating traffic delay. Although these two methods are already in service, they are operated independently. To combine these beneficial methods, this paper aims to develop “Status Map” which is based on the analysis of queuing pattern on the traffic network. Simulation on radial road section consists of paralleled urban expressway and arterial shows that significant relationship exists between Status Map and delay calculated on dynamic simulator, which implies that Status Map as a static framework would still be applicable to future traffic control method.
