High-Accuracy Tracking Using Ultrawideband Signals for Enhanced Safety of Cyclists

Abstract EN

In this paper, an ultrawideband localization system to improve the cyclists’ safety is presented.

The architectural solutions proposed consist of tags placed on bikes, whose positions have to be estimated, and anchors, acting as reference nodes, located at intersections and/or on vehicles.

The peculiarities of the localization system in terms of accuracy and cost enable its adoption with enhanced risk assessment units situated on the infrastructure/vehicle, depending on the architecture chosen, as well as real-time warning to the road users.

Experimental results reveal that the localization error, in both static and dynamic conditions, is below 50 cm in most of the cases.
