Summary

This project seeks the implementation of technologies that will bring direct and immediate benefits to the users and operators that are involved in the handling of collision sites and subsequent investigations. One primary objective of the proposed work is focused on the development of user specifications for a Global Positioning System (GPS) unit that can be readily used by CHP officers and crash site investigators to facilitate expedient documentation of collision sites. The availability of GPS data can further be incorporated into the data entry process and statistical analysis in SWITRS (Statewide Integrated Traffic Records System) and TASAS (Traffic Surveillance Accident Surveillance and Analysis System), which subsequently is used to derive critical information for highway improvements such as High Concentration Collision Location (HCCL Table C) and to perform safety studies. The deliverables for the project include technological tools and training seminars for CHP and Caltrans safety and operational personnel. The outcome of this research project will bring considerable direct and indirect benefits in safety improvements and congestion relief towards achieving the goals of Caltrans on mobility, efficiency, and safety.
