Optical barriers for vehicle detection and classification in tolls(MAPS CFxx)
They are exclusively developped for detecting vehicles taking into account the geometry and kinematics of these passing through the screen. Designed for outdoor operation, support direct sunlight, direct rain, dirt, degraded mode support system des / activating sensors affected by external agents (small animals, dirt, etc).
Main Functions:
- Vehicle Detection.
- Vehicle Classification.
- Separation between vehicles.
- Height over the first axle.
- Tow Presence.
- Axle Counting (double beam model).
- Vehicle crossing direction (double beam model).
Description of Optical Barriers MAPS CFxx
Maps designs and manufactures since 1996 optoelectronic devices for detection and classification of vehicles in tolls.
The technology used is based on the creation of one or two planes of infrared light that, when crossed by
vehicles, produces certain information that is processed by the device, and provides the following functions:
Main Functions:
- Vehicle Detection.
- Vehicle Classification.
- Separation between vehicles.
- Height over the first axle.
- Tow Presence.
- Axle Counting (double beam model).
- Vehicle crossing direction (double beam model).
Detection and / or classification of vehicles in tolls is characterized by an extremely harsh environment. This variability has been fully addressed in the design and manufacture of the CFxx photoelectric curtains which have continuous improvements for more than 10 years. This environment, under which barriers work properly, could be summarized as follows:
- Environmental conditions: direct sunlight, hard shadows, rain .
- Dirt environment: tree leaves, paper or packs moved by the wind, flying animals or crawlers, etc .
- Variability of objects detected: motorcycles, cars, trucks, with all the variability at low, either fixed or hanging objects, etc.
The current configuration of the optical barriers is the result of years of development, conducting countless tests with real traffic and the experience of thousands of devices running on motorway tolls from various countries.
The cornerstones on which rests the great success of this product by our customers are:
- Their high reliability on the procided information (errors of 1 / 10,000 in vehicle detection [reliability = 99.99%]).
- High Performance independent of the speed of passing vehicles.
- It provides a large number of useful functions for traffic management.

Vehicle classification table by number of axles and height with MAPS CFxx Optical barriers
In contrast to other classification systems operating by volume of the vehicle, Maps CFxx optical barriers are installed
on either side of the road so it does not need a portico. Classification reliability at low speeds is maintained
even with totally congested or stopped traffic.
