Abstract

Systems and methods for detecting a traffic event include receiving vehicle data from a plurality of vehicles travelling along a roadway. The method also includes where the roadway is discretized at a cell level into a plurality of cells. The method also includes identifying vehicles of interest that are within a communication range of a host vehicle. Each of the vehicles of interest are associated with a cell of interest from the plurality of cells. Further, the method includes for each cell of interest at each timestep according to a measurement update interval, calculating an average deceleration based on vehicle data transmitted from each of the vehicles of interest associated with the cell of interest. Additionally, the method includes detecting the traffic event based on the average deceleration for each cell of interest at each timestep.
