Development of disaggregate models for estimating different property damage collision type frequencies in urban intersections has rarely been studied, particularly in Iran. It seems very little research work being implemented for studying the effect factors on collision type frequency at intersections. The main objective of this paper is to develop suitable statistical models to predict types o...

Highlights Data from the Fatality Analysis Reporting System (FARS) and General Estimates System (GES) show that, in 2011, about 3 percent of fatal crashes, 1.7 percent of injury crashes, and 2 percent of property-damage-only (PDO) crashes involved single-unit trucks (SUTs). Crashes involving SUTs killed 1,064 people and injured about 38,000 people. Additionally, about 87,000 SUTs were involved ...

Abstract Due to urbanization and the significantly increasing number of vehicles, urban roads are becoming more congested day by day, with result that rear-end collision has become third most common type collision. By developing integrating active passive safety systems, car manufacturers working prevent accidents reduce consequences an accident. The present study examines a braking procedure i...

This paper examines the influence of collision scenario random variables on the extent of predicted damage in ship collisions. Struck and striking ship speed, collision angle, striking ship type and striking ship displacement are treated as independent random variables. Other striking ship characteristics are treated as dependent variables derived from the independent variables based on relatio...

This article presents information on bus collisions from the National Transit Database (NTD) and discusses implications of the findings on the design of transit collision warning systems. A total of 2,405 major transit bus collisions were reported in 2002 and 2003 that resulted in more than $15 million in property damage, 145 fatalities, and more than 8,000 injuries. According to the NTD, front...

A recurrent graph G has the infinite collision property if two independent random walks on G, started at the same point, collide infinitely often a.s. We give a simple criterion in terms of Green functions for a graph to have this property, and use it to prove that a critical Galton-Watson tree with finite variance conditioned to survive, the incipient infinite cluster in Z with d ≥ 19 and the ...

In the event of a collision between a traveling, high speed train and a vehicle, the scale of human fatality and property damage can increase substantially if the train derails from its track after impact. Hence, it is important to identify the conditions and factors that may potentially lead to derailment in the event of a train-vehicle collision incident at a highway rail grade crossing. This...

In rigid robotics, self-collision are usually avoided since it leads to a failure in the robot control and can also cause damage. soft situation is very different, self-collisions may even be desirable property, for example gain artificial stiffness or provide natural limitation workspace. However, modeling simulation of costly as requires first collision detection algorithm detect where collis...
