Patent Images
1. A traffic light control system comprising:
- at least one traffic signal apparatus;
a signal generator, contained within the traffic signal apparatus, that generates a signal within a frequency band of 57-64 GHz;
a transmitter, contained within the traffic signal apparatus, that transmits the signal;
a receiver, contained within the traffic signal apparatus, that receives a response to the signal; and
a computational device, contained within the traffic signal apparatus, communicatively coupled to the receiver that analyzes the response to the signal to determine if a specified condition is present.
