Smart sensors could end rail chaos of ‘leaves on the line’

A prototype sensor developed at the University of Birmingham, UK, is could end the annual autumn rail chaos caused by wet leaves on the line.  

Funded by EPSRC and the Rail Safety and Standards Board, Lee Chapman, Professor of Climate Resilience at the University worked with Alta Innovations, the University’s technology transfer company, to transform the concept into a reality.

His new technology, called AutumnSense, uses low-cost sensors to continuously measure the level of moisture on the railway line at potentially thousands of sites across the network.  By linking this data with a leaf-fall forecast, operators can identify where and when the risk is greatest.  This allows the precise and efficient use of automated treatment trains, which can clear the lines before the morning rush hour starts.  His team are now testing the next element of the solution which is a low-cost method to count the number of leaves remaining on the trees.

Professor Chapman’s team had previously developed low-cost devices that are fitted to lamp-posts, and transmit data on road surface temperatures, to show precisely where road gritting is needed, and where it isn’t.  The road technology, called WinterSense, is currently being tested by commercial partners and is expected to be in mass production by the end of this winter.  

Chapman is marketing AutumnSense and WinterSense through AltaSense, an operating division of Alta Innovations, and hopes to incorporate by autumn 2017.

    ASFINAG has developed a mobile traffic monitoring and guidance system through a pre-commercial procurement project. Drivers have become accustomed to roadside and gantry-mounted traffic guidance and control systems along the major roads and main motorway sections. But there are occasions when intense monitoring is required on a temporary basis along motorway sections without traffic guidance and control systems and on federal and national roads too. Examples include the monitoring of the traffic flow during

    Meteorological organisations invest millions in super-computers to crunch data for ever-more accurate forecasts but inherent unpredictability means that other methods of alerting drivers and road authorities to fast-changing weather and highway conditions are essential. For years, static weather sensors to measure factors such as surface water, ice or high roadway temperatures have been embedded in highways to provide such data. But that is changing.

According to the European Centre for Information and Communication Technologies (EICT) which provided management support, these “prove that CV systems work and can hav

    A UK university student researcher has made a breakthrough by designing and constructing a new system which ‘harvests’ the energy generated by a vehicle’s shock absorbers and feeds it back into batteries or electrical systems such as air conditioning. Ruichen Wang from the University of Huddersfield carried out the project to obtain his doctorate at the University and has published his findings. The article, Modelling, Testing and Analysis of a Regenerative Hydraulic Shock System, provides a summary of
