Traffic monitor and method
View Patent ↗In accordance with an embodiment, a method for processing information associated with vehicular traffic includes generating an input signal that contains information associated with vehicular traffic and transmitting the information to a cloud-based server system. A control signal is generated in response to the information. In accordance with another embodiment, a traffic monitoring system has a data aggregator coupled to a malfunction management unit and to a traffic signal controller coupled to the data aggravator.
1. A method for controlling traffic, comprising:
providing a data aggregator configured to receive data related to traffic or a traffic control cabinet, a traffic signal controller coupled to the data aggregator, and a malfunction management unit coupled to the traffic signal controller and to the data aggregator;
receiving the data related to the traffic or the traffic control cabinet at the data aggregator;
transmitting the data related to the traffic or the traffic control cabinet to a server system;
generating a control signal in response to the data related to the traffic or the traffic control cabinet that has been transmitted to the server system; and
using the control signal to control an intersection.
2. The method for controlling traffic of claim 1 , wherein receiving the data related to the traffic or the traffic control cabinet at the data aggregator includes receiving an input signal selected from the group of signals comprising a signal from an intersection monitor, a signal from a synchronized intersection, a signal from an unsynchronized 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 control unit, and a signal from a traffic data collector.
3. The method of claim 1 , further including using a Synchronous Data Link Control (SDLC) communications protocol to transmit traffic signal controller information.
4. The method of claim 1 , wherein generating the control signal includes generating the control signal to include a sync pulse that updates timing information in the traffic signal controller within the traffic control cabinet.
5. The method of claim 1 , wherein generating the control signal includes using a global positioning system to transmit the control signal.
6. The method of claim 1 , wherein the data related to traffic comprises a signal from one or more of an inductive loop, a magnetometer, a video detector, a radar, and a laser.
7. A traffic monitoring system, comprising:
a data aggregator having a first input terminal, a first output terminal, and an input/output terminal;
a malfunction management unit having an input/output terminal, the input/output terminal of the malfunction management unit coupled to the input/output terminal of the data aggregator; and
a traffic signal controller coupled to the data aggregator.
8. The traffic monitoring system of claim 7 , further including:
an antenna coupled to the first output terminal of the data aggregator; and wherein the data aggregator further includes a second input terminal coupled for receiving a time sync signal.
9. The traffic monitoring system of claim 7 , further including a time sync signal generator coupled to the data aggregator.
10. The traffic monitoring system of claim 7 , further including a cloud-based server system coupled to the traffic monitoring system.
