Atlanta’s reversible express lanes project opens

The I-75 South Metro reversible express lane project In Atlanta, Georgia, US, will open this weekend along almost 21km between Highway 138 and Highway 155 on the new double-lane addition to the I-75 median. The lanes will carry traffic northbound toward downtown Atlanta during the morning rush hour and southbound during midday and peak afternoon and evening traffic.

The I-75 South Metro reversible express lane project In Atlanta, Georgia, US, will open this weekend along almost 21km between Highway 138 and Highway 155 on the new double-lane addition to the I-75 median. The lanes will carry traffic northbound toward downtown Atlanta during the morning rush hour and southbound during midday and peak afternoon and evening traffic.
 
4089 Parsons prepared conceptual design reports for the project, including lane configuration and access studies, as well as the environmental document. The 754 Georgia Department of Transportation’s (GDOT’s) NaviGAtor software, a rebranded version of Parsons’ Intelligent NETworks advanced transportation management system, will monitor the express lanes. In addition, Parsons’ Intelligent NETworks has been installed at the State Roadway and Tolling Authority (SRTA) to display current toll rates on changeable message signs.

Intelligent NETworks will be used to display comparative speeds on dynamic message signs, showing the current average speed along the corridor for the express lanes and general purpose lanes. The software will also monitor the express lanes via traffic sensors and video cameras to help coordinate response to any incidents. Enhanced features will immediately notify roadway operators if a vehicle is detected travelling the wrong way. In addition, Parsons’ software allows for centre-to-centre connection between SRTA software and NaviGAtor to help automate coordination between the two agencies while operating the express lanes.

    To complement its existing WIM offering, IRD has introduced a system to detect under-inflated and flat tyres at highway speeds. Tyre inflation pressure has both safety and economic impacts for road users and none more so than with commercial vehicles. An underinflated tyre has decreased directional control, increased risk of catastrophic failure, and negatively impacts tyre life and fuel economy. In June 2014 the USDOT published Large Truck and Bus Crash Facts 2012 in which the Federal Motor Carrier Safety

    David Arminas visits Canada’s Highway 407 ETR to see how the concession is working and hear about new arrangements for the roadway’s extension. The Toronto region is North America’s eighth largest metropolitan area and its roads become notoriously congested. In 1997 Highway 407, a 68km concrete toll motorway which skirts the northern edge of Toronto, was opened and initially operated by the province and CHIC - a consortium of four leading Ontario-based companies. Finance came from the Ontario Financing Auth

    An impending move to free-flow charging prompted a search for automated dangerous goods identification and over-height detection systems at the Thames Crossing to the east of London. Manned toll booths are increasingly being consigned to history by the onslaught of all-electronic charging. However, a secondary function of the traditional manned plazas has been to prevent non-compliant vehicles using the facility or to tell a driver that that they need to use a specific lane or wait for an escort.

    High-speed weigh-in-motion is starting to make its mark on both sides of the Atlantic. As a transit country the Czech Republic experiences a large number of overloaded vehicles, which greatly increase highway maintenance costs. This prompted its Transport Ministry to trial an extension of the capabilities of the existing truck tolling system to allow the dynamic high-speed weighing of cargo vehicles. In effect the tolling enforcement gantries become weigh-in-motion (WIM) locations.
