Traffic validation system and method
In accordance with an embodiment, a method for processing information associated with vehicular traffic includes monitoring two signals that include information associated with vehicular traffic. A comparison signal is generated by comparing the two signals. The two signals may be wireless signals, or one of the two signals may be a hardwired signal.
1. A method for verifying information associated with vehicular traffic, comprising:
monitoring a wireless signal that includes wireless information associated with the vehicular traffic, wherein the wireless signal is a signal selected from a group of signals comprising a dedicated short range communication (DSRC) channel, a vehicle-to-vehicle (V2V) channel, a vehicle-to-everything (V2E) channel, a cellular vehicle-to-everything (C-V2X) channel, and a 5G frequency range;
monitoring a non-wireless signal that includes non-wireless information associated with the vehicular traffic; and
generating a comparison signal in response to comparing the wireless information associated with the vehicular traffic with the non-wireless information associated with the vehicular traffic;
wherein the wireless signal is transmitted by a roadside unit, and wherein the non-wireless signal is transmitted by the roadside unit.
2. The method of claim 1 , further including generating an error signal in response to the comparison signal.
3. The method of claim 1 , further including using the comparison signal as an error signal.
4. The method of claim 1 , further including storing the wireless information associated with the vehicular traffic.
5. The method of claim 1 , further including storing the non-wireless information associated with the vehicular traffic.
6. The method of claim 1 , further including storing the comparison signal.
7. The method of claim 1 , further including ranking the at least one of the wireless information associated with the vehicular traffic or the non-wireless information associated with the vehicular traffic.
8. The method of claim 1 , wherein the wireless signal is at one of 5.8 GigaHertz or 5.9 GHertz.
9. A traffic control system, comprising:
a traffic monitor having a first input, a second input, and an output;
a first traffic signal source transmissively coupled to the first input of the traffic monitor;
a second traffic signal source transmissively coupled to the second input of the traffic monitor; and
a comparison circuit configured to compare a first signal from the first traffic signal source with a second signal from the second traffic signal source, and further configured to generate an error signal when the first signal and the second signal do not match and transmit such error signal to the traffic monitor such that the output of the traffic monitor directs a flashing signal by a traffic signal head.
10. The traffic control system of claim 9 , wherein the first traffic signal source is transmissively coupled to the first input of the traffic monitor through a hardwired electrical interconnect.
11. The traffic control system of claim 10 , wherein the second traffic signal source is transmissively coupled to the second input of the traffic monitor through a wireless signal.
12. The traffic control system of claim 9 , wherein the first traffic signal source is transmissively coupled to the first input of the traffic monitor through a first wireless signal and the second traffic signal source is transmissively coupled to the second input of the traffic monitor through a second wireless signal.
13. The method of claim 1 , wherein the comparison signal is configured to generate an error signal when the wireless signal and the non-wireless signal do not match and the error signal is transmitted to a traffic signal controller for display of a flashing signal by a traffic signal head.
