ACCIDENT DATA USE AND GEOGRAPHIC INFORMATION SYSTEM (GIS)

Project Description: The Cheyenne Area Transportation Planning Process (ChATPP) has developed a PowerPoint presentation demonstrating how to use an existing accident database with GIS software. The slides are followed by a hands-on demonstration of the GIS system using the actual data. ChATPP has been intensely involved and a leader in GIS development in the City of Cheyenne and Laramie County. Recently they have taken the steps to try and interest users, that are not GIS technical people, in the use of ArcView in a desktop application. One of the projects that has been developed, is making accident data obtained from Wyoming Department of Transportation (WYDOT) available to ArcView users. How this project was developed is explained briefly below. What is important to stress is that the information is available to users. It is also important to demonstrate to them how the software works. Background: The Cheyenne urban area has a population of approximately 72,000 people. They have a slow but steady growth of about 1% and they are the northern most city along the rapidly growing Front Range in Colorado. The Metropolitan Planning Organization (MPO) is responsible for transportation planning in the urban area. To assure the safety of the traveling public as the population grows, they are looking at access management standards for their main arterials. Need: Their first step was to establish if there was a need for access management standards. The number and cause of collisions are the main determinate of the safety of the roadway. So, they needed to be able to examine, in depth, the collisions that occurred along their arterial roadways to determine if they could be prevented by having access control measures in place. GIS: The Wyoming Department of Transportation is responsible for collecting all of the accident information in Wyoming. Using an extract of the state's database, they obtained database files for accidents from 1984 to 1996. The files were then put into ArcView GIS to create maps of specific locations or to use the database for queries. The end result could then be displayed graphically as well as in tabular form. The GIS also allows inquiries on the map that is linked to the database.
