URBAN TRAFFIC MANAGEMENT, Scotland, Gleneagles Pedestrian Crossing

BEAR Scotland,

Challenge

SWARCO Traffic Limited was contacted by BEAR Scotland to provide detection with advance warning of pedestrians crossing the A9 between Gleneagles railway station and Gleneagles village,

Specific requests were for a solution that was economical to procure and maintain with ongoing support to allow modifications to the configuration and detection arrangement to suit possible future changes to the pedestrian access layout.

Details

SWARCO Traffic Limited was able to provide detection for both sides of the carriageway along with a protected central reservation segment of the A9 utilising Flir Thermicam technology, allied to RF Solutions radio equipment in contact with two retroreflective displays featuring LED amber flashers warning approaching traffic of pedestrians on the carriageway ahead.

All parts of the system are mains powered.

The use of a network of Flir 390 Thermicams with variable focal lengths and viewing angles linked with configurable detection software enables the carriageway side accesses and central reservation to be monitored simultaneously as an active zone. The detection system is allied to a SWARCO controller providing display combinations where either one or both VAS are activated depending on the position of pedestrians detected. The controller also allows display activation and deactivation timing delays to be incorporated, allowing moving traffic to flow through the section without pedestrians walking alongside the carriageway creating false activations causing unnecessary disruption.

Benefits

The use of a Flir Thermicam network enables the system to detect pedestrians in all conditions, including at night and in inclement weather, ensuring that approaching drivers get the best warning in the worst conditions. The combination of a Flir configurable interface with SWARCO controller ensures that detection is not reliant on ground loops, meaning that the detection zones can be amended in the future if required with no change to the physical equipment specification. Pedestrians who stray from the conventional route of access are still protected as the area is monitored as a full zone rather than just narrow access ‘corridors’.
