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

Abstract

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.

UWB/Binocular VO Fusion Algorithm Based on Adaptive Kalman Filter

“…Bastida-Castillo et al also verified that the UWB positioning system has strong reliability, and the use of different devices does not have a significant impact on measurement error [13]. In order to feedback potential dangers to road users, especially cyclists, Davide et al [14] proposed a positioning system based on UWB technology. Bicycles were equipped with low-cost, low-complexity active tags and HMIs (human machine interfaces), and reference nodes were placed at intersections (infrastructure-based architecture) or vehicles (vehicle-based architecture).…”

Risk analysis of bicycle accidents: A Bayesian approach

“…A comprehensive analysis of the influence of multiple risk variables on accident severity was presented. Based on the ultrawideband (UWB) technology, Dardari et al (2017) proposed an UBWlocalization system to improve the safety of cyclists. Combined with enhanced risk assessment units, the peculiarities of the system in terms of accuracy and cost enable a real-time warning function to road users.…”

Positioning Improving of RSU Devices Used in V2I Communication in Intelligent Transportation System

“…The use of the impulse-radio ultra wideband (IR-UWB) localization technology in an outdoor environment has already been proposed [12], [13], [14], [15]. This technology provides high channel capacity (i.e.…”

“…the data is transmitted at a high rate) which makes is suitable for use in the V2I communication [12]. Also, propositions to employ the IR-UWB technology in the positioning of the objects on the road have been reported [13].…”
