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.

    Real time active traffic management improves travel times
    Traffic management centres (TMC) have traditionally served to provide surveillance and responses to traffic incidents and recurring and non-recurring changes in road networks. Typically, a TMC collected field data from the roadway and transit infrastructure and provided the integration necessary for operators to see what was happening and then coordinate a response. Standard operating procedures (SOPs) guided operators on how to respond to a given situation. It eventually became impractical for TMC operat

    I-80 Smart Corridor sets the ITS standard for California's Bay Area
    Colin Sowman looks at California’s ‘smartest’ road which will open this spring to counter congestion and accidents on one of the Bay Area’s busiest interstates. Interstate 80 (I-80) is one of the busiest roads in the San Francisco Bay area with up to 270,000 vehicles using the corridor every day. The section between the Carquinez Bridge in Crockett and the Bay Bridge not only suffers congestion during the working week but also at weekends. Traditional remedies such as building additional lanes (there are al
