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 system will be managed from a centralised control room in Oakland and the traffic signa

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.

Currently it takes four hours to make the 86km journey between Bogota and Villavicencio using the existing single lane in each direction road which passes through some very challenging terrain. It is the only ground connection between central Colombia and the eastern region which represents 40% of the country’s territory.

    As the deck renewal of the I-91 viaduct in Springfield gets underway, David Crawford looks at the preparation and planning to ease the resulting traffic congestion. Accommodating the deck renewal of a 4km-long/four-lanes in each direction viaduct in the heart of Springfield (Massachusetts’ third largest city), has involved the state’s Department of Transportation (MassDOT) in a massive exercise in transport research and ITS-based area-wide preplanning and traffic management. Supporting a workzone of well ab

    US eyes European model for Illinois toll road upgrade
    David Crawford welcomes the adoption of European-style ITS technology by the US. The Jane Addams Memorial Tollway in Illinois, US is well on the way towards becoming a ‘smart traffic corridor’, taking full advantage of active traffic management (ATM or ‘managed lanes’) technology that originated in Europe. It is one of the first American toll roads to do so; preliminary work began in 2014 and will continue through to 2016. Jane Addams is one of four toll roads operated by the publicly-owned Illinois State T
