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.

    Bridging the highway travel information gap
    A new traffic management solution is attempting to bridge the gap in information available on freeways and arterial roadways. Andrew Bardin Williams reports. Agencies responsible for national networks of roads around the world have the ability to measure, analyse and disseminate accurate travel information to drivers. Millions of dollars go into data collection infrastructure to collect traffic congestion and travel time information on major freeways or highways. For example, a driver on the I-210 in the Lo

    ITS needs data highways
    Transport and traffic data is on the increase but there must be an integrated data highway to derive the maximum ITS benefits, argues Deutsche Telekom. From public transport operators recording increasingly precise and comprehensive data on their vehicle’s position and driving behaviour to local authorities using RFID and video systems to control traffic on their streets and highways, the amount of traffic data is growing rapidly.

    Wireless bridges widen options for ITS upgrades
    Antaira Technologies’ marketing engineer Brian Roth explains why the increasing capacity of wireless bridges is reducing the cost of expanding and upgrading ITS networks. With more than half of the world’s population now living in cities, the need for efficient transportation of both people and goods has never been greater and that pressure is unlikely to ease any time soon. Indeed in many regions of the world the rate of urbanisation is still increasing as the demand for rural workers continues to decline.
