Abstract
A framework for precision traffic analysis estimates dilemma zone activity to dynamically adjust phase cycle timing for improved efficiency of traffic flow at a roadway intersection. The framework identifies a traffic detection area at or near a traffic intersection, and detects objects in the traffic detection area from sensors located proximate to the traffic intersection. The framework then correlates lapsed phase cycle times for the traffic signal with associations between object characteristics and known speed characteristics for the roadway for a determination of whether there is dilemma zone activity for the remainder of that phase cycle. The framework then determines whether to adjust a timing of the current phase cycle.
