Abstract

Evansville Urban Transportation Study (EUTS), the metropolitan planning organization (MPO) in Evansville, Indiana, recently developed a transportation information system (EUTSTIS). The initial version of the EUTSTIS is composed of three subsystems: inventory, including 24 tables, and numerous queries, forms, reports, macros, and modules; geographic information system (GIS), associated with Maptitude; and Tool Box, including eight programs to perform data processing in the data conversion, socioeconomic and land-use projection, model calibration, trip generation, emission estimation, and level-of-service analysis in the census transportation planning package. The key finding is that the capabilities of keeping information updated and consistent for travel modeling and other transportation studies can be considerably enhanced by implementing the simple and powerful database management system technology along with GIS. The practice in EUTS has proven that a comprehensive database is a very efficient and promising solution for the middle- and small-sized agencies to improve the quality of services at a minimum overall cost.
