Documentation
The Visual Interactive System for Transport Algorithms (VISTA) is an innovative system integrating data warehousing and analysis tools for a wide range of transportation users and applications. Potential users of VISTA include engineers and planners with state and local agencies, operators at real-time traffic management centers, decision-makers, policy-makers and general stakeholders. Applications, although limitless, include the evaluation of infrastructure improvements, the evaluation of impacts such as roadway closures, the placement and operation of ITS devices, roadway design, traffic control, etc.
