Is optical traffic signal preemption better than audio (siren-based) or radio-based systems?
All traffic signal preemption systems have trade-offs, so comparisons should be made based upon cost, operational requirements (range, ease of installation, etc.), and future expectations. However, it should be pointed out that by far the most prevalent traffic signal preemption technology is optical.
