How does a signal operate? Is a specific signal operating correctly?
Most signals in the City of Allen are controlled by traffic-detection cameras. Fog may affect the traffic detection, but the signal will correct itself as the fog lifts. The proper operation of signals can be checked remotely by computer, or in the field by traffic signal personnel. For specific questions about signal operations please contact the City's Engineering Department at 214.509.4576.
