Abstract: A system for detecting a sound level of vehicles comprising sensor units for detecting vehicles on a road and for measuring a sound level of a detected vehicle. A data processing unit is connected to the sensor units and has an identification recorder for operating the system by recording an identification of the vehicle detected if the sound level is above a given value.

Abstract: A system is provided to detect road traffic conditions and environmental conditions. The system having a detection apparatus for detecting and managing road traffic conditions and environmental conditions at a surveillance site, and for interpreting information collected, and for instance, simulate local surveillance. A telecommunications device is connected to the detection apparatus so as to transmit data to a remote server. The remote server receives data from the detection apparatus and is accessible to provide the data collected by the detection apparatus. A method for signaling speed derogations to a vehicle driver in road traffic. The method comprises the steps of: i) monitoring a road to detect movement caused by a vehicle; ii) measuring a speed of the vehicle detected in step i); and iii) signaling a warning if the speed is above a given value.
