Vantage Velocity® takes advantage of the large number of vehicles that are driving with Bluetooth enabled devices such as smart phones. Each Velocity field unit senses a bluetooth device's unique "MAC" address as it passes the field unit and transmits the time and location of the device to a central host system. As bluetooth devices are detected at successive Velocity field units, the Host System calculates average travel times and speeds for a roadway segment. The device's specific network address remains anonymous.
Flexible to meet any needs
Deploying several Velocity field units along an arterial corridor provides an efficient means to collect arterial travel times - one of the main challenges for traffic operators and engineers.
Field processing units are installed at various intersections in the road network. These capture the time a Bluetooth enabled device passes through the intersection and transmits the data back to the Host Software running on a central processor. The Host Software compares data from each of the intersections in the network, and if it finds a match, the time between intersections is calculated. The distance between those intersections in known and travel speeds are calculated.
