Cycling is an increasingly popular mode of travel in cities owing to the great advantages that it offers in terms of space consumption, health and environmental sustainability. However, cycling is still also perceived as relatively unsafe, and therefore it has yet to be adopted as a real alternative to the private car. Rising accident numbers, unfortunately, confirm this perception as reality, with a particular source of hazard (and a significant proportion of collisions) appearing to originate from the interaction of cyclists with Heavy Vehicles (HVs). For this purpose, the Cyclist 360° Alert system is currently being developed as a novel technological solution aimed at preventing cyclist-HV collisions. As an integral part of Cyclist 360° Alert, this paper focuses on the bicycle localization aspect and presents an approach based on low-cost micro-electromechanical systems (MEMS) sensor configurations on an instrumented prototype bicycle system, called “iBike”. The iBike has the capability of sensing its motion, which can be then analysed to compute the trajectory path with a targeted accuracy of 50 cm. The paper describes the iBike system architecture and presents the initial results from a validation field experiment using a total station, which investigates the applicability of specific sensor configurations in terms of sensor accuracy and reliability in taking sample measurements of motion.
