System and method of adaptive controlling of traffic using zone based occupancy
Systems and methods for triggering changes to traffic signals based on the number and/or types of vehicles occupying a detection zone are disclosed. One aspect of the present disclosure includes a device with memory having computer-readable instructions stored therein and one or more processors. The one or more processors are configured to execute the computer-readable instructions to receive identification of zones and corresponding traffic light rules for a traffic intersection; and for each identified zone, detect a number of objects in the zone; based at least in part on the number of objects detected in the zone, determine if a corresponding condition is met; and upon determining that the corresponding condition is met for the zone, send a corresponding output signal to a traffic signal controller to change a traffic signal for the zone.
1. A device comprising:
memory having computer-readable instructions stored therein; and
one or more processors configured to execute the computer-readable instructions to:
receive identification of zones and corresponding rules for a signalized roadway intersection, wherein a perimeter of at least one zone is based on user input at a graphical user interface of a traffic control system that is communicatively coupled to the device; and
for each identified zone:
receive traffic data from one or more sensors at the signalized roadway intersection;
detect a number of objects in the zone by performing one or more of image processing or video processing on the received traffic data;
based at least in part on the number of objects detected in the zone, determine if a corresponding condition is met; and
upon determining that the corresponding condition is met for the zone, send a corresponding signal to a traffic signal controller to change a traffic signal for the zone.
2. The device of claim 1 , wherein the corresponding condition is a threshold number of objects detected in the zone.
3. The device of claim 2 , wherein the corresponding condition further includes a type of objects detected in the zone.
4. The device of claim 2 , wherein the corresponding condition is further based on a traffic light condition of at least one other zone at the signalized roadway intersection.
5. The device of claim 1 , wherein the objects are vehicles.
6. The device of claim 5 , wherein the vehicles are one or more of a car, a truck, a bicycle or a motor cycle.
7. The device of claim 1 , wherein a size of each zone varies based on a time of day.
8. The device of claim 1 , wherein the zones and the corresponding rules are specified via the graphical user interface.
9. The device of claim 1 , wherein the device is the traffic signal controller configured to be communicatively coupled to traffic lights at the signalized roadway intersection.
10. One or more computer-readable medium having computer-readable instructions stored thereon, which when executed by one or more processors, cause the one or more processors to:
receive identification of zones and corresponding rules for a traffic intersection, wherein:
a perimeter of at least one zone is based on user input at a graphical user interface of a traffic control system that is communicatively coupled to the one or more processors; and
for each identified zone:
receive traffic data from one or more sensors at the traffic intersection;
detect a number of objects in the zone by performing one or more of image processing or video processing on the received traffic data;
based at least in part on the number of objects detected in the zone, determine if a corresponding condition is met; and
upon determining that the corresponding condition is met for the zone, send a corresponding signal to a traffic signal controller to change a traffic signal for the zone.
11. The one or more computer-readable medium of claim 10 , wherein the corresponding condition includes one or more of a threshold number of objects detected in the zone, a type of objects detected in the zone, and a traffic light condition of at least one other zone at the traffic intersection.
12. The one or more computer-readable medium of claim 10 , wherein a size of each zone varies based on a time of day.
13. A method of zone-based traffic controlling, comprising:
receiving identification of zones and corresponding rules for a traffic intersection, wherein:
a perimeter of at least one zone is based on user input at a graphical user interface of a traffic control system; and
for each identified zone:
receiving traffic data from one or more sensors at the traffic intersection;
detecting a number of objects in the zone by performing one or more of image processing or video processing on the received traffic data;
based at least in part on the number of objects detected in the zone, determining if a corresponding condition is met; and
upon determining that the corresponding condition is met for the zone, sending a corresponding signal to a traffic signal controller to change a traffic signal for the zone.
14. The method of claim 13 , wherein the corresponding condition includes one or more of a threshold number of objects detected in the zone, a type of objects detected in the zone, and a traffic light condition of at least one other zone at the traffic intersection.
15. The method of claim 13 , wherein a size of each zone varies based on a time of day.
