Abstract:
1. method for analyzing on-road traffic density comprising: receiving, by a traffic management computing device, a user selection of a video image capturing device from among a plurality of video image capturing devices; receiving, by the traffic management computing device, a user selection of coordinates in one of one or more video image frames of an on-road traffic scenario captured by the selected video image capturing device such that the coordinates form a closed region of interest; the generating, by the traffic management computing device, at least a traffic confidence value or no traffic confidence value for each of the feature vectors to classify the sub-windows as having a high traffic value or a low traffic value by a traffic density classifier; computing, by the traffic management computing device, at least a traffic density value depending on a number of the sub-windows with a high traffic value and a total number the of sub-windows within the region of interest; comparing, by the traffic management computing device, the traffic density value with a first set of threshold values to categorize the video image frame as having low, medium or high traffic; and displaying, by the traffic management computing device, traffic density values at different instants in a time window to enable monitoring of a traffic trend.
