Each data set includes the position and the velocity of a vehicle as functions of time. For an intersection having a traffic signal, an average acceleration of the vehicles when leaving the intersection is estimated, and an average deceleration of the vehicles when approaching the intersection is estimated. For each of a subset of the vehicles, a stop duration at the intersection is estimated based on the average acceleration, the average deceleration, and the positioning system data for the respective vehicle. A duration of a red phase of the traffic signal is estimated based on the stop duration of each of the subset of the vehicles."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for estimating traffic signal information","description":"Traffic signal information is estimated based on positioning system data obtained from a plurality of vehicles.
