Abstract: In an approach for adapting traffic signal timing, a computer collects sensor data associated with a first intersection. The computer evaluates the collected sensor data with respect to predefined objectives. The computer determines whether a change in a state of a traffic signal for the first intersection should occur based at least in part on the evaluated collected sensor data with respect to predefined objectives. Responsive to determining the change in the state of the traffic signal for the first intersection should occur, the computer calculates a change to a traffic signal timing. The computer initiates an adaptation to the traffic signal timing based on the calculated change to the traffic signal timing.

Abstract: In an approach for adapting traffic signal timing, a computer receives a streaming video for one or more paths of a first intersection. The computer identifies traffic within the received streaming video. The computer calculates traffic flow for the one or more paths of the first intersection based on the identified traffic. The computer determines whether a change in a state of a traffic signal for the first intersection should occur based at least in part on the identified traffic and the determined traffic flow with respect to predefined objectives. Responsive to determining the change in the state of the traffic signal for the first intersection should occur, the computer calculates a change to a traffic signal timing based on the determined change in the state of the traffic signal. The computer initiates an adaptation to the traffic signal timing based on the determined change to the traffic signal timing.

Abstract: In an air conditioning system, the positions of the dampers in the outside air duct and the return air duct are changed periodically during periods of mechanical refrigeration. The temperature of the refrigerated air is sensed and compared with the temperature of the refrigerated air sensed prior to the change in damper positions. The positions of the dampers are controlled in accordance with the lowest temperature detected.
