Upgrade for Minnesota’s tolling system data integration

Following the US Department of Transportation’s Urban Partnership Agreement’s award to Minnesota DOT of the necessary funds to improve traffic flow on I-35W to and from downtown Minneapolis, Comtrol's DeviceMaster RTS 1-port was implemented to provide an Ethernet connection between all the toll tag readers along the I-35W corridor. The project consisted of retrofitting existing high-occupancy vehicle (HOV) lanes with technology that would enable single-occupant vehicles to use the HOV lanes. The toll lan

Following the 324 US Department of Transportation’s Urban Partnership Agreement’s award to Minnesota DOT of the necessary funds to improve traffic flow on I-35W to and from downtown Minneapolis, Comtrol's DeviceMaster RTS 1-port was implemented to provide an Ethernet connection between all the toll tag readers along the I-35W corridor.

The project consisted of retrofitting existing high-occupancy vehicle (HOV) lanes with technology that would enable single-occupant vehicles to use the HOV lanes. The toll lane had to be dynamically priced, meaning the toll rate would increase as traffic on the main lanes increased, allowing vehicles travelling in the high-occupancy toll (HOT) lane to maintain a speed of 55mph at all times no matter how congested the main lanes were, while an RFID toll tag in the vehicle registers the toll charge. Comtrol’s DeviceMaster gathers the serial information from each toll tag reader and transmits it via Ethernet to the main control.

    Private sector operator, Transurban, operators of Virginia’s I-495 express lane, has unveiled the highway’s incident management centre where the flow of vehicles will be monitored on a widescreen monitor displaying a dozen camera angles. The new lanes are expected to open by the end of fall. The centre will monitor traffic volume 24/7 in order to compute toll rates. The new roadway, connecting the Dulles toll road to the I-395/I-95/Springfield interchange fourteen miles to the south, will charge drivers dyn
