Abstract
A method is provided to generate a heat map to show traffic congestion based on transit points. The method includes generating, by a processing device, a trajectory database from time-stamped global positioning system (GPS) sample points, and computing transit points for each trajectory in the trajectory database. The method further includes constructing a temporal transit graph. The transit graph captures the shortest paths among the transit points. The method further includes indexing and storing the transit graph in a spatial-temporal database for online analytic processing.
