Claim One:
1. A vehicular traffic monitoring method comprising: obtaining an image of a traffic location, the image of the traffic location including an image portion; generating an image mask, the image mask being dimensionally representative of the image portion; masking the image of the traffic location using the image mask to obtain the image portion, the image portion including at least one vehicular image object; identifying the at least one vehicular image object from the image portion; and determining a traffic density representative of the image portion based at least in part on the at least one vehicular image object by: detecting an edge of the at least one vehicular image object; drawing an image-bounding box around the edge of the at least one vehicular image object; translating the image-bounding box from a perspective coordinate frame to a world coordinate frame; determining an area of the image-bounding box in the world coordinate frame; determining an area of the image portion in the world coordinate frame; and determining the traffic density as a ratio of the area of the image-bounding box in the world coordinate frame to the area of the image portion in the world coordinate frame.
