Communication is key to I-80 implementation

The I-80 Smart Corridor is to use 133 energy-saving, low-light-pollution signs on the 31.4km (19.5miles) route between the Oakland Bay Bridge and the Carquinez Bridge in California. Due to open next year, the US$80m project will see adaptive metering at 44 on-ramps (with bus priority and HOV bypass) and the new signs will be used for lane management and to advise drivers of incidents and variable speed limits.

The I-80 Smart Corridor is to use 133 energy-saving, low-light-pollution signs on the 31.4km (19.5miles) route between the Oakland Bay Bridge and the Carquinez Bridge in California.

Due to open next year, the US$80m project will see adaptive metering at 44 on-ramps (with bus priority and HOV bypass) and the new signs will be used for lane management and to advise drivers of incidents and variable speed limits.

The system will be managed from a centralised control room in Oakland and the traffic signal timing will be coordinated with local streets with all information shared with the other administrations along the route.

    Managed lanes have something of a patchy track record and can pose authorities problems as well as solutions. Many authorities in the US and beyond have converted, or are converting, parts of the highway network into ‘Managed Lanes’ and charging motorists a fee to avoid the delays on the adjoining free use lanes. Some authorities have converted underused High Occupancy Vehicle (HOV) lanes into priced-managed high occupancy/toll lanes (HOT lanes) whereby the price charged can vary depending on a number of fa

    Achieving higher diversion rates has helped one Kansas city to make traffic flow more efficient around workzones. David Crawford examines what’s behind a 10:1 benefit-to-cost ratio in Wichita Around 10% of highway congestion in the US results from delays in workzones, leading to an estimated annual loss of $700 million in fuel costs alone. The lack of accessible real-time traffic information to help motorists minimise their inconvenience – particularly at peak times - is a major contributor. One solut

    A major initiative in managing numerous transport networks as a single system has moved into a significant phase with design of sophisticated new ITS systems. Jon Masters reports. Detailed design work is under way on two pilot projects pursuing a common principle – that transportation can be made more efficient or effective if the various networks and modes of travel are managed as a whole system. This is the central tenet of the US Department of Transportation’s (USDOT) Integrated Corridor Management (ICM)
