Abstract:Illegal removal of road barricades without notice of road emergency officials and road users has resulted in fatalities, injuries, and property damages. It is only after an incident has occurred or someone noticed the removal and alerted the authorities for the barricade to be placed back at its intended location. Due to this event, traditional barricades must be equipped with mechanisms to alert emergency officials and warn road users of impending danger. This research utilized the Global Positioning System (GPS) module, and Radio Frequency (RF) modules to detect barricade movements, and alert emergency officials and road users. The barricade movements were estimated from the haversine distance formula, corrected for errors, and then compared with the distance threshold value for the road users within a geofenced area to be alerted. The geofenced area radius was estimated to be 1.04 miles from the barricade location using the American Association of State Highway and Transportation Officials (AASHTO), National Safety Council (NSC), and TransGuide ITS manuals. The non-parametric bootstrapping method was used to estimate the GPS position error to 10.5 feet and corrected the measured distances. Experimental data of the system from a clear sunny day shows that low-cost GPS modules have the best response to barricade movements compared to a cloudy day where movements can’t be explained easily. This system can communicate with Road-Side Units (RSUs) and On-Board Units (OBUs) and is expected to warn road users and alert emergency officials.
