CARTIM uses V2V architecture to estimate the traffic’s
LOC (Level Of Congestion). The information is obtained
through periodic exchange of beacon messages between vehicles,
by which each vehicle informs its neighbors of its
speed and current location. In order not to overload the communication
channel with messages, the message transmission
frequency in the algorithm is initially set to 0.5 Hz, i.e. a
beacon is broadcast by a vehicle every 2 seconds.
