摘 要：The seven Florida Department of Transportation (FDOT) districts are multicounty districts that each interact with a number of county and municipal agencies, including local transit agencies. FDOT District 7 includes the Tampa-St. Petersburg-Clearwater areas, which are among the most populous and complex in the state. District 7 employees regularly need information from the many entities that may interact with transportation planning, design, construction and maintenance. Accessing this information usually nvolves multiple manual steps to locate, acquire, and convert data. To facilitate their work, District 7 has initiated an effort to create an electronic means for intraregional data sharing.
