This study investigates the relationship between occupant injury and a host of other factors, including traffic and weather conditions present at the time of crash, road design, vehicle type, and occupant characteristics. Crash and traffic-detector data from six Orange County freeways were used in an ordered probit model. Crash outcomes were classified for each occupant, as no injury, non-visib...

This paper proposes an approach to overcome some limitations of the 802.11e protocol highlighted in recent literature and improve the QoS support provided to realtime industrial traffic. The proposed solution does not change the IEEE 802.11e protocol, but introduces a technique to reduce the number of collisions and therefore to use the channel more efficiently for real-time traffic, especially...

Cooperative communication(CC) is a promising technique to combat fading in a wireless environment. In our previous work, we proposed Cooperative Preamble Sampling(CPS)-Medium Access Control(MAC) protocol which highlighted the benefits of using CC in Wireless Sensor Networks(WSN). Initially, CPS-MAC performance was evaluated in a 3-node network comprising a single source, partner, and destinatio...

Reliable data extraction is essential to achieving a high-level understanding of the processes ongoing in the traffic environment. The ability to extract 3D structural properties of vehicles enables advanced traffic analysis such as vehicle classification and the detection of traffic rule violations, accidents, and near-collisions. A novel method is presented for extracting 3D structural proper...

This paper attempts to give the solution for the urban scenario using DV cast protocol. Normally DV cast protocol is the best solution for highway traffic. But this paper proposed urban dv cast (UDV) protocol to deal with the urban traffic. This UDV protocol is extension of DV cast protocol. Our aim is to address the urban scenario where vehicles are equipped with sensors or wireless devices to...

BACKGROUND Pediatric traumatic brain injuries (TBIs) have not been well studied in China. This study investigated characteristics and trends of hospitalized TBIs sustained by Chinese children. METHODS AND FINDINGS We analyzed 2002-2011 hospitalized TBI patients (0-17 years of age) treated at a large pediatric medical center in China. TBIs were defined using the International Classification of...

A case series of five patients is described demonstrating the utility of the intubating laryngeal mask airway in the prehospital setting, both as a primary airway rescue device and as a bridge to tracheal intubation. All patients were hypoxaemic, had sustained severe polytrauma and were trapped in their vehicles following road traffic collisions. A probability of survival study showed better-th...

Recently, wireless body area networks (WBANs) have attracted significant consideration in ubiquitous healthcare. A number of medium access control (MAC) protocols, primarily derived from the superframe structure of the IEEE 802.15.4, have been proposed in literature. These MAC protocols aim to provide quality of service (QoS) by prioritizing different traffic types in WBANs. A contention access...

Aloha-type random-access protocols have been employed as access-control protocols in wireline and wireless, and stationary and mobile, multiple-access communications networks. They are frequently employed by the control and signaling subsystem of demand-assigned multiple-access protocols for regulating the sharing of a multiaccess communications channel. The correct design and sizing of the ran...
