Consideration of Signal Phase and Timing Control
The SBIR is specific for signal controlled intersections, as that is where the dilemma zone occurs. But how much, if any, consideration should be given to methods adapting signal timing based upon the results? For example, if the system predicts which vehicles will be in the dilemma zone, should it also suggest signal timing to minimize the number of vehicles that will be in the dilemma zone?
Wei Zhang commented
Suggesting adaptive changes to the signal timing plan so that the number of vehicles caught in dilemma zone would be minimized is a plus. Implementing the adaptive changes to signal timing may require signal controller specific knowledge. For the topic, the minimum requirement is to be able to detect the signal phasing status at time of event logging.
