Borlänge, Sweden
Tracking individual vehicles @ 100 km/h
Trafsense® was selected by the Swedish Transport Administration (STA) as reference measurement system on STA’s test site consisting of 2+2 carriageways. The position and lane of each individual vehicle are updated 65 times per second, meaning that a vehicle typically moves less than 0.43 m between each Trafsense® update.
The speed limit is 100 km/h and Trafsense® ensures that the measurement data from the STA’s different point sensors along the test site can be correctly correlated to the passing individual vehicles. This is due to Trafsense® capability of identifying lane changes as well as overtaking without losing track of the individual vehicle. Customized data formats and interfaces have been developed to apply real-time Trafsense® data for studies of individual vehicle behavior, traffic patterns, and traffic statistics:
Trafsense® real-time tracking of northbound vehicles at the Swedish Transport Administration’s test site on E16 near Borlänge (Sweden), consisting of 880 m 2+2 carriageway. Blue color: The vehicle is in the right lane. Red color: The vehicle is in the left lane.
Note that in total four vehicles in the right lane slow down and exit around 720 m. The real-time Trafsense® position data for each vehicle are updated 65 times per second.
The Trafsense® interrogation unit is located in a 19” rack in the red shed together with technical infrastructure for other sensor technologies installed by the Swedish Transport Administration.
