Using intelligent transportation systems to enhance pedestrian safety at Beirut signalized intersection

Around 25 percent of the injuries accidents in Greater Beirut Area (GBA) are pedestrian's related crashes of which 45% occur at signalized intersection. The high percentage of pedestrian victims of road accidents is due to the lack of traffic control devices and the absence of knowledge of the pedestrian rights to cross the roadway and most of the times pedestrians have exceptional safety needs and tasks that must be addressed. Recent improvements in intelligent transportation systems (ITS) show great potential in assisting to reduce the number of injuries, fatalities and the costs associated with crashes knowing that the primary beneficiaries are pedestrians. The target of this paper is to select the most effective and appropriate ITS treatments that can really affect mobility, safety and environmental developments in GBA Al-Ghazal signalized intersections using the vehicle to pedestrian (V2P) and the pedestrian to infrastructure (P2I) communications and technologies as traffic signals adjustments, automated pedestrian detection (APD), and countdown pedestrian signal (CPS). In addition, we will check the effect of those treatments on the pedestrian-vehicle conflict.
