AUTOMATED VEHICLE SPEED MEASUREMENT AND ENFORCEMENT METHOD AND SYSTEM
First Claim
1. A method for measuring vehicle speed, said method comprising:
- continuously monitoring traffic utilizing an image capturing unit and a controller;
estimating the speed of at least one vehicle within an effective field of view of said image capturing unit;
triggering a burst of radiation from an associated remote sensing device when said at least one vehicle is detected with a speed greater than a predetermined value; and
determining an accurate speed of said at least one vehicle.

Abstract
An automated vehicle speed measurement and enforcement method and system. Traffic can be continuously monitored utilizing an image capturing unit and a controller. The speed of one or more vehicles within an effective field of view of the image capturing unit can be estimated. A burst of radiation from an associated remote sensing device can be triggered when a vehicle is detected having a speed greater than a predetermined value. An accurate speed of the vehicle can then be determined. Additionally, a transverse velocity component associated with the vehicle can be computed by the image capturing unit in order to thereafter apply the transverse velocity component to a reading generated by the remote sensing device to correct a cosine error with respect to the remote sensing device.

12. A system for measuring vehicle speed, said system comprising:
-
an image capturing unit and a controller that continuously monitors traffic, such that the speed of at least one vehicle is estimated within an effective field of view of said image capturing unit; and a remote sensing device that is triggered by said controller to emit a burst of radiation when said at least one vehicle is detected with a speed greater than a predetermined value in order to determine an accurate speed of said at least one vehicle. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
