DIVERT Evaluation Report (Report on 'During Incidents Vehicles Exit to Reduce211 Time')

摘要

Two major freeways (I-94 and I-35E) come together in a common section in the211u001evicinity of downtown St. Paul. The Minnesota Department of Transportation Office 211u001eof Advanced Transportation Systems and the City of St. Paul jointly developed and 211u001edeployed an incident management project under the acronym DIVERT (During 211u001eIncidents Vehicles Exit to Reduce Time) to manage the effects of incidents on I-211u001e94 and I-35E. The goal of DIVERT is to provide management strategies during 211u001eperiods of freeway incidents by routing diverted traffic over City surface 211u001earterials in a planned, coordinated manner. One of the major initiatives of the 211u001eDIVERT project was to improve the joint management of freeway and city traffic 211u001ethrough enhanced institutional cooperation between Mn/DOT and the City of St. 211u001ePaul. This enhanced cooperation would allow the DIVERT objectives to be achieved 211u001ethrough a three phased process of incident detection, route guidance and traffic 211u001esignal control. In so doing, DIVERT links together two significant systems 211u001e(Mn/DOT Freeway Management System and City of St. Paul central based traffic 211u001esignal control system for its downtown network) which formerly had no linkages or 211u001einteractions.
