SYSTEM AND METHOD FOR IDENTIFICATION OF TRAFFIC LANE POSITIONS
First Claim
1. In a traffic monitoring system having a sensor, a method for defining traffic lanes, comprising the steps of:
- a. for a selectable plurality of vehicles, i. detecting each of said selectable plurality of vehicles present within a field of view of said sensor;
ii. estimating a position of said each of said selectable plurality of vehicles;
iii. recording said position of said each of said selectable plurality of vehicles;
b. generating a probability density function estimation from each of said position of said each of said selectable plurality of vehicles; and
c. defining said traffic lanes within said traffic monitoring system from said probability density function estimation.

Abstract
A method for dynamically defining traffic lanes in a traffic monitoring system is presented. A traffic system sensor detects vehicles passing within the field of view and process the data into an estimation of the position of each of the detected vehicles. The positions are defined and recorded for use in a probability density function estimation. The traffic lane positions are defined such that further detection of vehicles may be assigned to a particular traffic lane without requiring manual set-up and definition of the traffic lane boundaries. The traffic lane boundaries may change or migrate based upon modification of traffic paths due to construction, weather, lane re-assignments and the like.
