Abstract

This paper focuses on road patrol service which is carried out to remove and repair the road hazards risks, and addresses the methodology to make a. decision on the rational road patrol policy based on the trade-off relationship between its service level and budget constraint. Specifically, the road hazards generation process is formulated by Poisson Gamma, model in which the population parameter, that is arrival rate, is stochastically distributed, to express the heterogeneity of arrival rate of various road hazards risks. Employing this Poisson Gamma. generation model, the Management indicator of road hazard risks can be modeled. Furthermore, under the budget constraint, the rational road patrol policy that can mitigate the road hazard risks is proposed and applied for an empirical study.
