ABSTRACT In this project we developed a new GPS-based Geographical Information Exchange Framework (GIEF) to improve the correctness and accuracy of location data reported on electronic police forms in Oklahoma. A second major goal was to provide a base level of automatic vehicle location (AVL) technology to the Oklahoma Highway Patrol (OHP) to improve operational efficiency and inter-agency asset coordination and to enhance police officer safety. The GIEF was successfully developed and integrated with the existing statewide electronic police forms system and was deployed to a select group of OHP Troopers for beta testing. The beta tests demonstrated that high quality position data were acquired from GPS receivers in the field during actual police operations, were used to populate electronic crash reports and citations, and were automatically transmitted to the main Department of Public Safety (DPS) data warehouse and to the statewide court system. High resolution position data were also acquired on a continuous basis for all of the beta test police vehicles and were stored in a new secure data base created for this project. These data were used to demonstrate real-time AVL functionality that will be evaluated by the OHP to determine how it can best be used in the future to improve police operations and officer safety. The enhanced position data provided by this project will be important to a wide range of traffic safety stakeholders for planning and assessing highway improvement projects, highway safety projects, and law enforcement activities directly in terms of public safety impact. The GIEF is fully upwards compatible with the new PARIS system scheduled for deployment in 2013. 17. KEY WORDS 18. DISTRIBUTION STATEMENT GPS, Emergency Management, No restrictions.
