GIS in Transportation Operation: The City of Dallas Pilot Project
Maria DurcanskaDallas is experiencing economic and population growth, which places an increased demand on transportation. The City of Dallas, Department of Public Works and Transportation, is attempting to utilize GIS tools to manage existing transportation resources and enhance the efficiency of transportation operations. This paper discusses the pilot project of the transportation GIS program. The objective of the program is to build a transportation-related spatial database and GIS applications. Data from a variety of sources are integrated into one database accessible by transportation staff through ArcView GIS. Data on traffic volumes, speed limits, location of traffic accidents, characteristics of major thoroughfares, location of signalized intersections, and school zones is processed and made available to the staff. A combination of traffic volume and accident data is used to calculate intersection/street severity index and identify high accident locations. Future enhancements of the system include geocoding information from the citizen request database (requests for traffic signals, signs, and pavement markings) and information from the street cut permit database. This paper shows how GIS benefits different sections of the Transportation Division - District Engineering, Signal Engineering, Transportation Planning, and Field Operation - in their effort to improve the traffic operations in the City.
