The system produces a volumetric count and vehicle classification along representative road stretches, collecting information for future roadway planning, economic structures and engineering projects.

The measurements are achieved through two inductive loop sensors, installed in the road pavement, which detect passing vehicles. As each vehicle possesses magnetic mass, due to its metal volume, a magnetic variation is generated when the vehicle passes through the loop sensors, leaving behind a magnetic profile. Analysis of magnetic profile also makes it possible to distinguish size and speed as well as classify fleets according to their individual categories: motorcycles, automobiles and trucks, buses and carts.

The statistical traffic data is automatically transmitted to the Processing Center for analysis and registration, generating reports that show vehicle statistics 24 hours a day as well as their classification which includes quantities, categories sizes and speeds.

Roadway planning

The constant analysis of data at strategic points allows Traffic authorities to evaluate the existing traffic flow and make a more detailed estimate of the vehicles that transit monitored areas. This contributes in:
• Road planning, knowing the local traffic and establishing a classification of the road system;
• The evaluation of the occupation program and the use of land according to the volume of vehicles;
• The estimation of polluting emissions on roads;
• The identification of priority improvements needed on roadways;
• Changes in profiles throughout different seasons;
• Obtaining background information on traffic volume in urban areas and highways to establish future traffic projections;
• Estimating deterioration time for pavement;
• Studying the best location for police, weighing, medical and emergency posts;
• Locating and projecting installation points for the monitoring and inspection operations.
