Traffic sensor detects vehicles and
pedestrians
Cambridge Consultants has developed a novel intelligent activity sensor for vehicle and pedestrian detection, and will demonstrate it at RTIC 2004.
Cambridge Consultants has developed a novel intelligent activity sensor for vehicle and pedestrian detection, and will demonstrate it at RTIC 2004 - the International Conference on Road Transport Information and Control - at The IEE, Savoy Place, London, UK from 20th to 22nd April 2004 Based on state-of-the-art ultra-wideband radar, the sensor's imaging capability allows it to provide a complete picture of traffic and pedestrian presence and movement at crossings or junctions - reducing the number of sensors required while providing more accurate information

Radar technology "sees through walls"
Cambridge Consultants (CCL) has successfully demonstrated a radical new type of radar technology that can "see through walls".
System-on-chip service cuts electronics costs
Cambridge Consultants has set up a new service to allow enterprises without specialist electronics skills to exploit the benefits of SoC technology.
For example, a pedestrian crossing such as the UK's Puffin system might use Doppler radar to sense approaching vehicles, induction loops in the road to detect stationary traffic, and infrared to sense pedestrians.
Cambridge Consultants' ultra-wideband or UWB radar provides all this information in one compact and easy-to-fit module, providing a complete image of activity with presence, direction and speed data on objects in its field of view.
"UWB radar sensing provides vehicle and pedestrian detection that is more effective for both authorities and road-users, and lower in cost", says Jon Garnsworthy, Head of Transport Systems at Cambridge Consultants.
The radar technology is a spin-off of Cambridge Consultants' work on anticollision radar for automobiles, and operates in the unlicensed 5.8GHz frequency band using extremely low power signals.
The sensor module prepared for RTIC is intended to demonstrate how compact such multifunction sensors can be made, and is available as a reference design for integration by traffic equipment OEMs.
Alternatively, CCL can provide development services to adapt or interface the sensor for any specific equipment and sensing application.
