The Traffic alert and Collision Avoidance System (TCAS) was designed to prevent mid-air collisions by portraying a time-critical “resolution advisory” (RA) to the pilot. Complying with a TCAS RA is generally considered the safest course of action and takes priority over all other forms of air traffic management; however, pilot compliance with TCAS RAs is surprisingly low. One proposed solution ...

Introduction Blunt Traumatic Aortic Injury (BTAI) refers to tearing of the wall of the aorta, a serious, often fatal, injury that occurs during severe automobile collisions. BTAI is one of the most common causes of death in road traffic accidents [1], and may be caused by other impacts, such as in fall victims. Despite 150 years of speculation on the subject, however, there is still widespread ...

Received: September 8, 2017 Revised: November 24, 2017 Accepted: January 10, 2018 Abstract: Background: Collisions between pedestrians and reversing vehicles in public settings have received little attention in France. Yet, according to the national statistics on traffic accidents, reversing vehicles are involved in 6.5% of the 11,700 pedestrian accidents recorded each year (over the 2008-2015 ...

Estimating individual probabilities of causation generally requires prior knowledge of causal mechanisms. For traffic accidents such knowledge is often available and supports the discipline of accident reconstruction. In this paper structural knowledge is combined with Bayesian network methods to calculate the probability of necessity due to speeding for each of a set of vehicle/pedestrian coll...

Many sensor network applications feature bursty traffic patterns: after long periods of idle time with almost no network traffic, large amounts of data have to be transmitted reliably and in a timely manner. One example is volcano monitoring [8], where precious high-volume data is generated by rare volcanic eruptions. Unfortunately, existing MAC protocols do not sufficiently support such applic...

Up to 1 billion birds die annually in the U.S. from window collisions; most of these casualties represent migratory native species. Because this major mortality source likely contributes decline North American avifauna, mitigation tools are needed that accurately predict real-time collision risk, allowing hazards be minimized before fatalities occur. We assessed potential use weather surveillan...

The causes of crashes on urban expressways are mostly related to the unsafe behaviors drivers before crash. This study focuses sideswipe collisions expressways. Through real and visual crash data, 17 were identified for analysis an expressway. chains high-risk then revealed investigate relationship between drivers’ collisions. A Bayesian network diagram was used obtain correlation their influen...

Rear-end collisions are caused by drivers misjudging urgent risks while following vehicles ahead in most cases. However, compared with other accident types, rear-end have higher preventability. This study aims to reveal the prone segments and hours of collisions. First, we extracted 1236 cases from traffic records Harbin 2015 2019. These accidents classified as property damage accidents, injury...
