1. A traffic light control system for controlling a first traffic light, the system comprising:
- an event administrator module structured and/or programmed to receive and/or determine a plurality of input variables; and
a traffic light control algorithm module structured and/or programmed to receive the input variables from the event administrator module, to determine light status control information for the first traffic light, and to output the light status control information to the first traffic light to control operation of the first traffic light;
wherein the plurality of input variables includes at least a first event prediction related variable.

11. A traffic light control system for controlling a first traffic light, the system comprising:
-
an event administrator module structured and/or programmed to receive and/or determine a plurality of input variables; and a traffic light control algorithm module structured and/or programmed to receive the input variables from the event administrator module, to determine light status control information for the first traffic light, and to output the light status control information to the first traffic light to control operation of the first traffic light; wherein; the light status control information effectively determines a traffic light cycle, a plurality traffic light intervals occurring within each traffic light cycle and a plurality of interval delta values according to the plurality of traffic light intervals; and during at least some portions of normal operations, the traffic light control algorithm module determines light status control information so that at least one of the plurality of traffic light intervals changes in an at least a minimally continuous manner. - View Dependent Claims (12, 13)

14. A method of controlling accumulation of vehicular traffic at an intersection comprising the steps of:
-
providing data concerning a first access to the intersection; calculating a first vehicle access arrival frequency function for vehicles entering the intersection from the first access; providing a control mechanism to control vehicles leaving the intersection from the first access, the control mechanism having a control function; and modifying the control function based on changes to the first vehicle access arrival frequency function. - View Dependent Claims (15, 16, 17, 18)
