IV. INTRODUCTION

1. CONCEPT

The TMS-SA is a compact, self-contained and portable traffic counter.

The battery, memory and sensor are contained in a single housing;

- It is installed alongside the road;

- It is discrete;

- It is not in direct contact with passing vehicles;

- It is silent

- The technology used makes the equipment impermeable to cold, heat, mist, surrounding

pollution, variations in light, humidity, etc. Note however very heavy rainfall (sudden shower

or flurry, combined with gusts of wind during a storm for example) can create false

detections (parasitic measurements) in the receding direction (measurement of vehicles

moving away). The Icoms Software automatically detects the false detections due to rain. It is

then up to the user to decide to filter out the data to erase the undesirable measures. The

function of this filter is explained further in this document, p. 23

2. FUNCTIONS

The equipment enables the counting of vehicles, speed measurement and classification of vehicles

according to length, with a record of the date and time of passing of each vehicle. It saves the

measured data for each vehicle.

The software supplied with the equipment enables a precise and complete analysis of the data.

3. TECHNOLOGY

This is a Doppler effect radar, using the same technology as enforcement radars.
