Currently, most of the incident management (IM) teams depend on paper maps and informationsheets when traffic diversion is warranted in the presence of a major accident. These paper mapsare not only difficult to use in the presence of an emergency situation, they are also difficult tomaintain to ensure up-to-date information. A customized computer based system that takesadvantage of Geographical Information Systems (GIS) is the best solution for accessing andmaintaining these diversion maps and related other information. This paper describes a generalframework and basic functions based on GIS for traffic incident management operations andlong-term asset management of the equipment used for IM.The proposed tool Traffic Incident Management System (TIMS) is developed usingVisual Basic (VB) programming language and GeoMedia Pro1, GIS software package. A majorinnovation of this application is the development of a VB based computer program that automatesthe efficient merging operations of multiple incident management plans for any complextransportation network. Response strategies implemented using this application include GISbased traffic diversion plans, assignment of static and dynamic variable message signs todiversion points, and database of capabilities of responding agencies. The application offers“intelligent electronic maps” that can present the user the related diversion route and variablemessage sign locations along with the list of messages and agencies to be contacted, when theaccident link of interest is identified on the GIS map. Diversion routes and other information canalso be easily updated through the same Graphical User Interface (GUI), which has user-friendlydata editing properties. Message signs are efficiently attached to electronic information datasheets that can be accessed and updated by the user through the same interface. Therefore, theapplication not only provides real time traffic incident management information to the trafficoperators through a GIS based GUI but allows him to maintain an accurate database. The paperaims to demonstrate the utility of dynamic diversion maps and visual elements to ensure incidentpreparedness, and assist transportation agencies and also public safety agencies with aninnovative asset and information management tool that facilitates the deployment of effectivetraffic incident management strategies. This tool is hoped to obviate the need for paper maps andmanuals that can contain obsolete information that is difficult to update in a timely manner.
