Siemens traffic solutions improve Amsterdam bottleneck

Solutions supplied by Siemens are helping to improve traffic conditions at the Coentunnel, one of the most heavily used traffic arteries in the Netherlands, used by 100,000 vehicles every day. The tunnel, which links Amsterdam to the province of North Holland, has been a cause of traffic congestion and delays for many years.

Solutions supplied by 189 Siemens are helping to improve traffic conditions at the Coentunnel, one of the most heavily used traffic arteries in the Netherlands, used by 100,000 vehicles every day.

The tunnel, which links Amsterdam to the province of North Holland, has been a cause of traffic congestion and delays for many years. A much-needed second tunnel opened in spring 2013, together with a three kilometre long elevated section of freeway connecting the tunnel with the southern part of the city to relieve the heavily-used A10 route.

At the heart of the solution is the tunnel control centre's Sitraffic ITCC, which monitors and manages all of the operating and traffic systems and all of the outdoor equipment. A closed-circuit television system (CCTV) provides traffic monitoring, while the integrated automatic incident detection (AID) system provides identification of smoke as well as congestion and accidents.

Siemens also equipped the elevated section with state-of-the-art traffic technology including a traffic management system, monitoring technology and technical infrastructure components such as communication and camera technology.

To meet stringent safety requirements for the elevated section, Siemens used safety technologies similar to those used in the tunnel: sensors along the elevated section measure traffic volume and flow and automatically notify the control centre in the event of stationary traffic, slow-moving vehicles and wrong-way travel.

    The city of Abilene, Texas, in the US is using new adaptive traffic control software from Siemens to increase traffic flow along a heavily travelled corridor, where two state highways meet at two intersections about 750 feet apart with elevated railroads passing between them. SEPAC Peer-to-Peer software allows intersection controllers to share information with one another on traffic and pedestrian conditions, allowing the on-street network of controllers to adaptively respond to changing traffic conditions

  • Temporary CCTV poses more challenges than permanent installations
    June 12, 2015
    Long-term roadworks pose particular problems for temporary surveillance installations. Converting the hard shoulder to a running lane, either full- or part-time, is the UK Highways Agency’s solution to ease motorway congestion. This is leading to a number of long-term projects where large stretches of the hard shoulder are closed off by temporary concrete barriers and during these roadwork programmes, temporary CCTV cameras are deployed to monitor and record vehicle traffic and workers.

    Wrong-way warning systems and advanced queue detection can help to reduce human error. They can also cut road accidents – and therefore road deaths, says Clearview Intelligence Where were nearly 1,800 deaths on the UK’s roads in 2018 – an average of five people dying each day. The largest single cause of serious injury is crashes at junctions (accounting for 33% of incidents), while the largest single cause of death was run-off road crashes (30%) “With vehicles increasingly being designed with saf

    Every year in America cost benefit analysis is carried out on dozens of ITS installations and pilot studies and the findings, along with the lessons learned, are entered into the Department of Transportation’s (USDOT’s) web-based ITS Knowledge Resources database. This database holds more than 1,600 reports and periodically the USDOT reviews the material on file to draw conclusions from this wider body of evidence. It has just published one such review ITS Benefits, Costs, and Lessons Learned: 2014 Update Re
