Validation Testing
After setup has been finalized it is important to test the system.
The first phase of testing should be to observe any sources of
radar “noise” and to adjust the settings and aim to exclude this
noise.
The system can be “reversed” to test on live “right-way” traffic.
Alternatively, and preferably, the road section should be shut
down and live wrong-way testing be performed. We have
developed the following test script for reference...

Notes
This test can be expanded to as many lanes of entry as necessary, we have limited it to three (3)only for
reference. Where alternative methods of detection are utilized (loops, push buttons, etc) the test will
still be effective, though additional hardware settings may be required on the detection hardware. We
have seen this test expanded upon, with different vehicle sizes noted, expanded speeds added, and
additional environmental influences (trains in motion, for example) considered, consider this a starting
point for your own tests.
Notes
Procedure- Where RSUT closure is not permissible; it is feasible to test the system off of active, right way
traffic. The control of speed and traffic volume is inherently impossible in this scenario. System test will
rely on sufficient observation of traffic activating the system from specific lanes of entry. It is advised
that tests occur during hours that traffic is expected to be low; specifically, gaps between passing
vehicles results in improved accuracy and is most indicative of an average wrong way event. With the
assistance of TraffiCalm systems team, these tests can be performed remotely. To perform this test, the
system will be set up in “reverse” of its final configuration. For example, a system consisting of 2 radars
in the Pre-Alert Zone and 2 radars in the Alert Zone, all detecting approaching traffic (wrong way traffic)
will be configured with 2 radars in the Confirmation Zone and 2 radars in the Alert Zone, all set to detect
receding traffic. It is critical that the detection aiming remains identical throughout the test to ensure
proper operation in Wrong Way mode. Once the test is complete, the system can be configured to
wrong way mode by reversing the changes set.
Where ramp closure is not possible
