Traffic monitor and method
In accordance with an embodiment, a method for controlling traffic in response to information associated with vehicular traffic includes receiving a signal at an input of a data aggregator and transmitting the signal to a server. A control signal is generated in response to signal transmitted by the data aggregator. The control signal is used to control traffic.
1. A method for controlling traffic in response to information associated with vehicular traffic, comprising:
receiving at least one input signal at an input of a data aggregator, wherein the at least one input signal contains the information associated with the vehicular traffic or information about a traffic control cabinet;
transmitting the information associated with the vehicular traffic or the traffic control cabinet to a data analytics server;
generating one or more control signals in response to the information associated with the vehicular traffic or the traffic control cabinet; and
using the one or more signals to improve traffic controller timing.
2. The method of claim 1 , wherein the traffic information comprises vehicle data comprising one or more of vehicle presence, vehicle counts, vehicle travel time information, and vehicle travel information.
3. The method of claim 2 , wherein plurality of input signals comprises signals from one or more of an inductive loop, a magnetometer, a video detector, a radar, or a laser.
4. The method of claim 1 , further including receiving the at least one input signal from a group of signals comprising a signal from an intersection safety monitor, a signal from a synchronized intersection, a signal from a traffic data collection apparatus, a signal from a parking management monitor, a signal from a police door, a signal from a traffic controller, and a signal from a traffic data collector.
5. The method of claim 1 , further including using a Synchronous Data Link Control (SDLC) communications protocol to transmit traffic signal controller information.
6. The method of claim 1 , wherein generating the one or more control signals includes generating the one or more control signals to include a sync pulse that updates timing information in the traffic control device.
7. The method of claim 6 , wherein generating the one or more control signals includes using a global positioning system.
8. The method of claim 1 , wherein receiving the at least one input signal includes receiving the at least one input signal through one of an analog detector interface or a digital detector interface.
9. The method of claim 1 , wherein receiving the at least one input signal at an input of a data aggregator includes receiving the at least one input signal in response to a signal selected from the group of signals comprising: a signal from an unsynchronized intersection, a signal from a synchronized intersection, a signal from a traffic cabinet door, and a signal from an intersection safety monitor.
10. The method of claim 1 , wherein using the one or more signals to control traffic further includes transmitting at least one of the one or more control signals to the data aggregator.
11. The method of claim 1 , wherein using the one or more signals to improve traffic controller timing further includes transmitting at least one of the one or more control signals to a Dedicated Short Range Communications (DSRC) radio transceiver.
12. The method of claim 1 , wherein using the one or more signals to improve traffic controller timing further includes transmitting at least one of the one or more control signals to the data aggregator and to a Dedicated Short Range Communications (DSRC) radio transceiver.
13. The method of claim 1 , wherein transmitting the information associated with the vehicular traffic or the traffic control cabinet to the data analytics server includes transmitting the information to a cloud-based server system.
14. The method of claim 1 , wherein transmitting the information associated with the vehicular traffic or the traffic control cabinet to the data analytics server includes transmitting the information to a local server.
15. A traffic control method, comprising:
receiving at least one signal containing information associated with vehicular traffic at a data aggregator, wherein the data aggregator transmits the at least one signal to a server;
generating at least one control signal in response to the at least one signal transmitted by the data aggregator; and
using the at least one control signal to control traffic.
16. The traffic control method of claim 15 , wherein the server is a cloud-based server system.
17. The traffic control method of claim 16 , wherein using the at least one control signal to control traffic includes transmitting the at least one control signal to the data aggregator.
18. The traffic control method of claim 16 , wherein using the at least one control signal to control traffic includes transmitting the at least one control signal to a Dedicated Short Range Communications (DSRC) radio transceiver.
19. The traffic control method of claim 16 , wherein using the at least one control signal to control traffic includes transmitting the at least one control signal via a cellular based communications system.
20. The traffic control method of claim 16 , wherein the data aggregator broadcasts a Media Access Control (MAC) address of a WiFi device to the cloud-based server system.
21. The traffic control method of claim 15 , wherein the least one signal containing information associated with vehicular traffic is generated from a signal source selected from the group of signal sources comprising an inductive loop, a magnetometer, a video detector, a radar and a laser.
22. The method of claim 15 , wherein the data aggregator is configured to transmit bluetooth signals, cellular based signals, or Wireless Fidelity (WiFi) signals to the server.
