Given the variability of ramps and roadways that Wrong Way Alert can cover, it is important to properly
test and verify system functionality. In our experience, a concise test plan results in effective
performance measures that can be relied upon for real world monitoring of dangerous wrong way
events. This script is the result of working with dozens of transportation engineers on real projects and
we feel it is comprehensive, but local knowledge and regulations should be considered when
implementing your own test plan. Note that this procedure is intended to be used after the system has
been configured. All tests should result in a full notification and warning devices being illuminated.
Procedure- Per governing guidelines, the road section under test (RSUT) shall be closed to permit
sufficient and safe passage of a single vehicle traveling the wrong direction at up to 45mph through all
potential lanes of entry; this may include medians and shoulders. The result should be twofold- complete
coverage resulting in notifications being sent from any possible wrong way driving scenario, and no false
detections after the RSUT is opened to live traffic. If a fail occurs, it is (typically) reasonably acceptable to
adjust radar aiming and configuration, and then restart the test.
Notes
