Data Fusion for Vehicle Detection Using Radar and Loops For Intersection Decision Support (IDS)

E1ton Vorad (EVT-300) Doppler radar and loops are used to detect vehicle speed, distance to intersection and acceleration estimation. It turns out that speed based radar measurement and estimation are more accurate and have much less time delay than those from micro-loops, which is mainly caused by the time delays and measurement errors of the latter. Thus in data fusion, for moving vehicle speed and D2I estimation, much high 12 weight is put on radar. Loops, on the other hand, are mainly used for static vehicle detection or in the case when radar is found missing target for certain period of time. This work has also finds that both traditional loops and micro-loops are suitable for vehicle presence detection at a fixed point for traffic management where aggregated data is satisfactory. When time critical estimation is necessary, radar is better than loops.
