摘要

Analysis of incident data from Maryland Highway Administration leads to the conclusion that efficient operations of an incident management team can indeed contribute to reduction in not only the response time but also the clearance time. Hence, this paper presents an integerprogramming model for optimizing the deployment locations of emergency response units. Unlike most existing studies, the proposed model is designed to assign the available units to minimize the total delay caused by incidents, rather than to minimize their average response times. By giving more weights to locations likely to have more severe incidents and considering the variance of incident duration, the proposed model with the incident data from Maryland can outperform both the popular p-median model and state-of-the-practice deployment strategies. Extensive sensitivity analyses with respect to various traffic volumes and incident frequencies have also confirmed the superior performance of the proposed model with respect to minimizing the total delay caused by incidents.
