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.

    The new Hindhead Tunnel is the first in the UK to use radar-based incident detection. Paul Arnold, project manager with the Highways Agency, talks about the project. The comparatively remote location of the A3 Hindhead Tunnel has resulted in it becoming one of the most sophisticated in the UK in terms of monitoring and control systems, according to Paul Arnold, project manager for the Highways Agency (HA), which manages strategic roads in England and Wales. It is the first tunnel in the UK to use radar for

    Coordination is the key to successful integrated corridor management, argues Telegra’s chief operating officer, Branko Glad. The Centre for Economics and Business Research (CEBR) has calculated that in 2013, traffic congestion cost American citizens $124 billion ($78 billion of wasted time and fuel and $45 billion in indirect losses). In 2030 this figure is predicted to rise to $186 billion.

    Oregon Department of Transportation (ODOT) has implemented digital variable speed limit signs over a thirty-mile stretch of Interstate 84 between Baker City and La Grande, replacing the standard speed signs in that area. The new signs will use traffic, road, weather and visibility sensors to lower the legal speed limit when ice, snow, fog or a wreck ahead requires drivers to slow down. Along with identifying the current legal speed limit, the digital displays can also show the reason for a reduced speed,

    Mike Schagrin, ITS Joint Program Office, RITA, and John Harding, NHTSA, describe US progress towards an in-vehicle Intersection Violation Warning system. In 2008, there were 37,261 fatalities on US roadways. Of these, 7,772, some 20.8 per cent of the total, were defined as intersection crashes or intersection-related crashes. Through a multi-agency research initiative led by the Research and Innovative Technology Administration (RITA), the US Department of Transportation (USDOT) has developed a prototype In
