Abstract
In Taiwan, accidents involving scooters have contributed to more than 70% of the total number of injuries and fatalities in traffic accidents and the numbers have been increasing for the past 8 years; it is therefore crucial to derive cost-effective safety solutions which can be used in scooters. To this end, we propose a cost-effective collision avoidance system which utilizes non-line-of-sight (nLoS) communication links between vehicles on intersecting roads. IEEE 802.15.4 link measurements were carried out to investigate the path loss and the packet reception rates of those nLoS links in three different intersections. Analysis of the results suggests that nLoS links at intersections, while exhibiting high path loss, are still more than sufficient to support the required vehicle-to-vehicle (V2V) communications for the proposed system to avoid 99% of the possible collisions at intersections. ? 2012 IEEE.
