The client wanted to know the traffic circulating at five points on Bilbao's high-capacity road network (A-8 and parallel corridors), identifying the flows and routes currently chosen by drivers in their daily mobility, during a full working day (24 hours, from 00:00 to 23:59). For this work, number plates were read in order to identify vehicle trajectories, to obtain origins and destinations, as well as the time spent at each point.
Specifically, the axes analysed were the A-8 motorway and the N-637 road, both of which are important corridors in Bilbao's high-capacity road network, also connecting it with the entire northern part of the country.
The data collection was carried out with an artificial vision camera type survey device with Automatic Number Plate Recognition (ANPR) capability. The camera can recognise moving characters and record the time of their passage through the measuring point.
Compliance with the L.O.P.D. was guaranteed at all times, both the personnel in charge of image processing and the files are registered with the Spanish Data Protection Agency, and the corresponding audits were carried out to ensure compliance with the regulations.
