OBTAINING AN INDICATION OF A NUMBER OF MOVING OBJECTS PASSING SPEED DETECTION APPARATUS
First Claim
1. A method of obtaining an indication of a number of moving objects passing a speed detection apparatus, the method including:
- obtaining data representing a record of speed events over a series of time frames, each said time frame in the speed events record including a record of zero or more distinct speeds detected during that time frame;
analysing the speed events data to identify approach characteristics associated with one moving object approaching the detection apparatus;
analysing the speed events data to identify passing characteristics associated with the moving object passing the detection apparatus, andupdating a moving object count after detecting a said approaching characteristic and a said passing characteristic in sequence.

Abstract
Apparatus and method for obtaining an indication of a number of moving objects passing a speed detection apparatus. Data representing a record of speed events over a series of time frames is obtained (208, 210), each time frame including a record of zero or more distinct speeds detected during that time frame. The speed events data is analysed (604) to identify approach characteristics associated with one moving object approaching the detection apparatus. The speed events data is also analysed (606) to identify passing characteristics associated with the moving object passing the detection apparatus. A moving object count is updated (608) after detecting the approaching characteristic and the passing characteristic in sequence.
