3.1.Monitoring vehicles in roads
The group has performed monitoring of vehicles under contracts with the Ministry for the
Environment, Physical Planning and Public Works. According to these contracts, the group developed
sensors and systems to monitor the velocity of vehicles up to 250 km/h (Figure 4). Results have
