a spinal cord injury (sci) refers to any injury to the spinal cord or nerves at the end of the spinal canal that is caused by trauma instead of disease often causes permanent changes in strength, sensation and other body functions below the site of the injury. road traffic collision (rtc) or car crash occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other...

road accident severity may be influenced by a number of various systematic causal factors. the weather and road accidents have a close relationship with each other and a number of methods have been proposed for measuring the risk of a road accident with rainy, foggy, and snowy weather and high winds. recent studies indicate that road collision rates increase during precipitation. the weather wa...

this study is to report characteristics of people killed in road traffic crashes and to describe major patterns of traffic crashes in china.descriptive and inferential statistical analyses were conducted. road traffic death national data, population denominator data and motor vehicles data of 2009 were obtained from the bureau of traffic management at ministry of public security and national bu...

in recent years due to improvements of technology within automobile industry, design process of advanced driver assistance systems for collision avoidance and traffic management has been investigated in both academics and industrial levels. detection of traffic signs is an effective method to reach the mentioned aims. in this paper a new intelligent driver assistance system based on traffic sig...

Detection and recognition of traffic signs is an essential task of regulating the traffic, guiding and warning driver’s pedestrians. In traffic sign detection research are categorized into three groups. The first group of researchers believes that traffic sign detection colors are important information by which traffic signs can be detected and classified. The second group believes that detecti...

Evaluating Automated Anti-Icing Technology to Reduce Traffic Collisions Reducing fatalities, injuries, and property damage related to traffic collisions is a priority for road safety agencies. Traffic collisions result in more than 2,200 fatalities and 173,000 injuries each year on Canadian roads. Inclement weather is a contributing factor in traffic crashes for approximately 21 percent of the ...

We propose a range estimation method for vision-based forward collision warning systems with a monocular camera. To solve the problem of variation of camera pitch angle due to vehicle motion and road inclination, the proposed method estimates virtual horizon from size and position of vehicles in captured image at run-time. The proposed method provides robust results even when road inclination v...

Let OWRN = 〈Wx,Wy〉 be a One Way Road Network where Wx and Wy are the sets of directed horizontal and vertical roads respectively. OWRN can be considered as a variation of directed grid graph. The intersections of the horizontal and vertical roads are the vertices of OWRN and any two consecutive vertices on a road are connected by an edge. In this work, we analyze the problem of collision free t...
