Title

Enhancing Safety Through Advanced Proactive Traffic Management

Abstract

Proactive traffic management involves application of ITS (Intelligent transportation Systems) strategies that are specifically intended to reduce the risk of crash occurrence. It is an evolving paradigm for managing traffic on freeways that is proactive compared to incident detection. Incident detection, which has been of interest to traffic management authorities in the US and around the world, is essentially a reactive strategy. As the usage of cell phones and video camera surveillance on freeways have increased, the detailed algorithms analyzing traffic data to detect incidents have become irrelevant. Proactive traffic management strategies rely on reliable estimation of crash risk. The approach for developing crash risk estimation models uses historical crash and corresponding loop detector traffic data and is similar to the approach used to develop incident detection models. The aims of the two, however, are very different. In this study the differences between incident detection and crash risk estimation are addressed. Details of a proactive crash risk assessment system developed for Interstate-4 in Florida are also discussed in order to understand the implications of this new traffic management paradigm with regards to the current practices.
