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.

Well-established now in at least three European countries, Hard Shoulder Running (HSR) on motorways is exciting growing interest in the US. A November 2010 Report to Congress by the Federal Highway Administration (FHWA), on the Efficient Use of Highway Capacity, notes the role of HSR in the European-style Active Traffic Management (ATM) strategies now being recommended for implementation in the US where, until recently, they were virtually unknown.
