- TALEX TT warns the driver of an approaching speed by an initial voice alert at approximately 500 yards
- TALEX TT displays at the top of the TOM TOM screen the speed limit associated with the speed camera and the speed camera type
- If at 200 yards the vehicle is over the speed limit, TALEX TT will advise the driver to reduce speed
- TALEX TT sounds an alert as the speed camera is passed
- Lower cost locators typically use a Simple Zonal method. They advise the driver that they are approaching a camera by generating a warning whenever a vehicle crosses the boundary of a 500 yard circle centred on the camera position regardless of the vehicles direction. From the illustration above it can be seen that there are many roads within the red shaded 500 yard zone and will give rise to the possibility of many false alerts using the single activation point method.
- TALEX removes false alerts by using a two position activation method, using an initial activation point and a camera location. TALEX will only generate a warning when a vehicle passes an activation point and is driving towards the camera. Should a vehicle be driving from the opposite direction, the vehicle will not pass the activation point and no false alarm will be raised. If the driver joins from a side after the activation point, then TALEX senses the direction of travel and compares it with the direction of the speed camera and activation point and warns the driver of a speed camera ahead if driving in the direction of the camera.
