OBJECTIVE To determine whether drivers contacted at the roadside can be screened for alcohol use disorders (AUDs). Secondarily, to produce preliminary estimates of AUDs among drivers and estimate the relationship between AUD status and BAC measured at the roadside. METHODS A two-phase survey program was undertaken. In phase 1, 206 motorists were interviewed at the roadside using a 15-item AUD...

A vehicular ad hoc network (VANET) is the major element of intelligent transportation system (ITS). The purpose ITS to increase road safety and manage movement vehicles. known as one main components smart cities. As a result, there are critical challenges such routing in these networks. Recently, many scholars have worked on this challenge VANET. They used machine learning techniques learn proc...

one of the factors and tools necessary in managing roadside is rules and regulations without which, the area will face serious challenges in terms of the environment. recognizing rules of roadside was investigated in the current research, since some perturbations and irregularities related to the ecosystem of roadside are the results of rules and regulations and also complex damages appeared in...

Increased use of motor vehicles has produced various risks to human health due to air pollution by noxious gases, heavy metals and roadside dust. Since the late 1970s, the wide spread use of studded tires for cars has caused pavement wear, resulting in not only economic losses, but also roadside air pollution in cold and snowy regions in Japan. The most serious environmental problem in Sapporo,...

With the recent advances in fifth-generation cellular system (5G), enabling vehicular communications has become a demand. The ad hoc network (VANET) is promising paradigm that enables communication and interaction between vehicles other surrounding devices, e.g., vehicle-to-vehicle (V2V) vehicle-to-everything (V2X) communications. However, such networks faces many challenges due to mobility of ...

Vehicular Networks are receiving a lot of attention due to the wide variety of services they can provide. Their applications range from safety and crash avoidance to Internet access and multimedia. A lot of work and research around the globe is being conducted to define the standards for vehicular Communications. These include frequency allocation, standards for physical and link layers, routin...

Roadside units (RSUs), which have strong computing capability and are close to vehicle nodes, been widely used process delay- computation-intensive tasks of nodes. However, due their high mobility, vehicles may drive out the coverage RSUs before receiving task processing results. In this paper, we propose a mobile edge computing-assisted vehicular network, where can offload nearby via vehicle-t...

Vehicular edge networks (VENs) connect vehicles to share data and infotainment content collaboratively improve network performance. Due technological advancements, growth is accelerating, making it difficult always mobile devices locations. For vehicle-to-vehicle (V2V) communication, are equipped with onboard units (OBU) roadside (RSU). Through back-haul, all user-uploaded cached in the cloud s...

Collisions with dangerous roadside obstacles and rollovers are responsible for many injuries and deaths in highways worldwide. International crash data indicate that roadside characteristics contribute to more than half of all run-off-road injury crashes (RORIC) involving serious injury or death. Furthermore, roadside geometric characteristics are believed to be the leading cause of rollover in...

Motorcycle crashes with roadside objects often involve more than one impact event: typically involving a collision with the ground and another object. The objective of this study was to determine the fatality risk in these roadside object collisions when compared with crashes only involving a collision with the ground. The roadside objects analyzed included guardrails, concrete barriers, signs,...
