Siemens enhances loop detector

Siemens has enhanced the functionality of its SLD4 loop detector which now features length-based classification with configurable outputs which can be set to activate when specific conditions are detected, such as large vehicles exceeding a predefined speed. The detectors offer standard vehicle detection and are also suitable for use in bus, tram and light rail transport (LRT) schemes and other applications where high detection accuracy is required.

Siemens SLD4 loop detector
189 Siemens has enhanced the functionality of its SLD4 loop detector which now features length-based classification with configurable outputs which can be set to activate when specific conditions are detected, such as large vehicles exceeding a predefined speed.

The detectors offer standard vehicle detection and are also suitable for use in bus, tram and light rail transport (LRT) schemes and other applications where high detection accuracy is required.

Designed for maximum reliability and using the latest inductive loop detection algorithms, SLD4 detectors are fully compliant with UK specification TR2512 and provide four separate detection channels with full solid-state outputs. For challenging or special applications, a PC support tool enables many aspects of the detector’s functions to be accessed for specific deployments.

The detectors may be powered from either AC or DC supplies. Low power requirements, with operation possible at voltages as low as 10V DC, makes support within battery powered equipment a viable option.

    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

    David Crawford mines the potential of joined-up parking. Drivers conventionally see parking as an isolated, often frustrating, action; but collectively their attempts to find a space impact hugely on traffic flows. But new analyses of parking events look set to deliver real benefits to motorists and cities alike. Initiatives getting under way around the world are highlighting the advantages of connecting up parking events and – eventually - parked cars. The hoped-for results include not only enhanced urban

    It would be easy to fall into the trap of seeing machine vision as the vision-based solution for ITS and traffic, however Patrik Anderson, Director Business Development Transportation of Axis Communications, notes that many of the applications which are coming to be associated with machine vision – and, indeed, many of the characteristics, such as at-the-edge analytics and image processing – are also possible with open-standard networked video. Networked video brings a whole host of advantages, such as the
