Person-to-infrastructure (P2I) wireless communications for work zone safety enhancement

There are serious concerns about the injuries and fatalities of highway maintenance and construction workers around work-zone area. One portion of such incidents is directly related to the vehicles approaching work zones. The advance warning of the potential conflicts between vehicles and workers to both vehicle drivers and workers is essential to workers' safety. This paper proposes a Person-to-Infrastructure (P2I) communication framework aiming to enhance the work zone safety level. The Time Difference of Arrival (TDOA) based emitter location algorithm is identified to constantly monitor the location of an emitter attached to a worker. An engineering implementation procedure is proposed with nine practical steps. The on-going work includes further computer simulation and pilot test of such P2I wireless communication system.
