What term describes "false calls" and interference from adjacent loops?

The term that describes "false calls" and interference from adjacent loops is cross-talk. In traffic signal systems, cross-talk refers to the unintended interaction or interference between two or more sensor loops. This can lead to erroneous signals being generated, as one loop may incorrectly trigger due to the influence of signals from nearby loops. As a result, vehicles may be detected inaccurately, leading to issues like premature signal changes or delays at intersections.

Understanding cross-talk is crucial for technicians because it highlights the importance of proper installation, calibration, and maintenance of sensor loops to minimize such interference. This ensures that traffic signals operate efficiently and provide accurate data about vehicle presence and flow, which is essential for effective traffic management.

The other terms, while relevant in different contexts, do not specifically address the situation of false calls from adjacent loops as directly as cross-talk does.
