Abstract (en)
A system for monitoring transit of vehicles along a highway section (2), the system having a number of transmitting-receiving stations (4a, 4b, 4c) installed along the highway section and forming part of a wireless sensor network; each of the transmitting-receiving stations (4a, 4b, 4c) being configured to communicate with the other transmitting-receiving stations (4a, 4b, 4c), and having an independent power source, and a charging device for charging the independent power source; and the system being characterized in that a number of pairs (A 1 , A 2 , A 3 , A 4 ) of the number of transmitting-receiving stations (4a, 4b) are configured to operate: - in a first operating mode (ACTIVE), in which transit of vehicles along the highway section (2) is detected, and the type of vehicles in transit along the highway section (2) is determined; and - in a second charge operating mode (SLEEP), in which the charging device for charging the independent power source is activated; and in that at least one pair of transmitting-receiving stations (4a, 4b) operates in one of the first and second operating modes (ACTIVE, SLEEP), which differs from the operating mode of the other pairs.
