1. A computer-implemented method for analyzing on-road traffic density comprising:

  • a. allowing a user to select a video image capturing device from among a plurality of video image capturing devices;

    b. allowing the user to select coordinates in one of the 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 (ROI);

    c. processing the ROI, wherein the processing comprises;

    i. segmenting the ROI into one or more overlapping sub-windows,ii. converting the one or more overlapping sub-windows into one or more feature vectors through a textural feature extraction technique;

    d. generating a traffic confidence value or no traffic confidence value for each of the feature vectors by a traffic density classifier;

    e. computing a traffic density value depending on a number of sub-windows with high traffic and total number of sub-windows within the ROI;

    f. comparing 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

    g. displaying traffic density values at different instants in a time window to enable monitoring of a traffic trend.
