Delegates to the ITS AP Forum will have an opportunity to visit Kuala Lumpur’s Stormwater Management & Road Tunnel (SMART), a unique solution to the Malaysian capital’s long-term traffic and stormwater management problems – the first tunnel of its kind in the world. The dual-purpose tunnel can divert floodwaters away from the confluence of two major rivers running through the city centre, while its central section doubles up as a twin deck motorway to relieve traffic congestion at the main southern gateway into the city centre.

SMART, which cost some US$515M and opened to traffic in May 2007, comprises 9.5km of tunnel with the central 3km incorporating the double deck motorway. There are three modes of operation:
Mode one operates under normal conditions when low rainfall means that no water needs to be diverted into the tunnel. Moderate storms activate mode two, when floodwater is channelled into a bypass tunnel in the lower section of the motorway tunnel, enabling it to remain open to traffic; during the once or twice yearly heavy Monsoon storms a switch is made to mode three when the tunnel is closed to road traffic and the full tunnel section, with a combined capacity of three million cubic metres, becomes available to divert the dramatically increased flows of water.

    Substantial savings from smarter street lighting
    As authorities strive to reduce expenditure and carbon emissions, Colin Sowman looks at some of the smart ways of managing street lighting while containing costs and maintaining safety. Street lighting can account for 40% of an authority’s energy consumption. So, faced with the need to reduce outgoings, some authorities are looking for smart ways of managing street lighting or even turning off swathes of street lights in the small hours. Back in 2008 the E-street Initiative report concluded that authorities

    Monitoring, detection and control systems inside tunnels can do much to improve traveller safety
    ITS technology can do a great deal to improve tunnel safety, as Colin Sowman discovers. It was back in April 2004 that the European Parliament adopted the EU Directive which lays down the Minimum Safety Requirements for Tunnels in the Trans-European Road Network (2004/54/EC). This was the first unitary legislation setting minimum safety standards for European road tunnels and was designed to harmonise the management of tunnel safety at a national level. Operators of existing tunnels have until 30 April 201

    Hard shoulder running aids uniform traffic flow and safer driving
    David Crawford detects a market for European experience. 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.

    UK's Hindhead tunnel pushes the boundaries of traffic management
    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
