Infrared detectors are presently installed at two locations
for curbside detection. When the pedestrian is detected, flashing beacons
are activated to warn motorists of the pedestrian in the vicinity of the
crosswalk. The beacons at SW Natio Parkway and Couch Street are mounted
overhead, while those at SW Greenway and Talbot are post-mounted on the
curb.

Microwave
Sensors SmartWalkTM detectors are currently installed at the intersection
of NE Sandy Boulevard and 18th Avenue and are being used to extend the clearance
interval for pedestrians requiring additional crossing time. The City is
pleased with the preliminary evaluations, which show the devices to work
very well. As a result, policies are being developed for future installations.
