Abstract

To evaluate the impact of ITS technologies for incident management systems, a three-level incident delay model was proposed to estimate the average delay caused by incidents. In this model, incident delay was expressed as a function of incident duration, severity, and frequency, each of which was further modeled by advanced econometric models. Using this approach, the effect of the incident management programs on incident duration, severity, and frequency and, subsequently, average incident delay can be analyzed for various conditions. A case study was presented to demonstrate the way in which the proposed approach may be utilized in evaluating the impact of ITS technologies in incident management system.
