VDOT VaTraffic

Status:

Existing

Definition:

Tthe Virginia Traffic Information Management System (VaTraffic), is an upgraded traffic information management system that will replace the Virginia Operational Information System (VOIS) currently in use by the Virginia Department of Transportation (VDOT). VaTraffic is designed to improve VDOT operations by providing a more efficient and advanced integrated data management platform for managing a variety of activities that affect the quality of travel experienced by motorists in the Commonwealth. It is a network of applications that VDOT staff will use to manage planned events such as roadway maintenance, unplanned events such as traffic accidents, and to provide information for other VDOT systems. VaTraffic will provide VDOT operations staff with an integrated tool to collect, monitor, update, and disseminate roadway information via the Data Gateway more efficiently than possible with the system currently in place. VDOT staff will also use VaTraffic to direct information to the 511 Integrated Voice Recognition (IVR) system and Website to provide pre-trip and en-route traveler information to the public, and to other interested users within VDOT.
