Abstract
Present disclosure provides methods and apparatuses for adaptively controlling traffic signals. A method for adaptively controlling traffic signals based on a traffic control plan comprises identifying, by a processor, an external intervention occurring at an intersection, the external intervention causing traffic control behaviour at the intersection that deviates from the traffic control plan; and modifying, by the processor, the traffic control plan based on the traffic control behaviour caused by the external intervention.

A method for adaptively controlling traffic signals based on a traffic control plan, comprising:
- identifying, by a processor, an external intervention occurring at an intersection, the external intervention causing traffic control behavior at the intersection that deviates from the traffic control plan;
- and
- modifying, by the processor, the traffic control plan based on the traffic control behavior caused by the external intervention;
- determining a control plan of the external intervention and a resultant traffic flow at the intersection based on the traffic control behavior caused by the external intervention;
- determining traffic flow at a neighboring intersection of the intersection;
- generating one or more control plans for the neighboring intersection from one or more simulations, the one or more simulations having simulation inputs based on variations of the control plan of the external intervention, the resultant traffic flow at the intersection and the traffic flow at the neighboring intersection;
- and
- storing the generated one or more control plans as pre-learned control plans with their corresponding simulation inputs.
An apparatus for adaptively controlling traffic signals based on a traffic control plan, comprising:
- a memory in communication with a processor, the memory storing a computer program recorded therein, the computer program being executable by the processor to cause the apparatus at least to:
- identify an external intervention occurring at an intersection, the external intervention causing traffic control behavior at the intersection that deviates from the traffic control plan;
- and
- modify the traffic control plan based on the traffic control behavior caused by the external intervention;
- determine a control plan of the external intervention and a resultant traffic flow at the intersection based on the traffic control behavior caused by the external intervention;
- determine traffic flow at a neighboring intersection of the intersection;
- generate one or more control plans for the neighboring intersection from one or more simulations, the one or more simulations having simulation inputs based on variations of the control plan of the external intervention, the resultant traffic flow at the intersection and the traffic flow at the neighboring intersection;
- and
- store the generated one or more control plans as pre-learned control plans with their corresponding simulation inputs.
