Finite Element Analysis of the Effect of Low-Speed Rear End Collisions on the Medial Meniscus
<p>Low-speed, rear end vehicle collisions can inflict soft tissue damage to the passenger’s knees, especially the medial meniscus, which has been previously unexplained in published literature. It is difficult to determine if factors such as age or other injury was the primary cause of the injury …

The Use Of The Ucf Driving Simiulator To Test The Contribution Of Larger Size Vehicles (lsvs) In Rear-end Collisions And Red Light Running On Intersections.
… The U.S. Department of Transportation spends millions of dollars every year on research that aims to improve roadway safety and decrease the number of traffic collisions. In spring 2002, the Center for Advanced Traffic System Simulation (CATSS), at the University of Central Florida, …

Prospects for the Collision-Free Car: The Effectiveness of Five Competing Forward Collision Avoidance Systems
Rear-end collisions in which the leading vehicle was stationary prior to impact and at least one vehicle was towed from the crash site represent 18% of all yearly crashes in the United States. Forward Collision Avoidance Systems (FCASs) are becoming increasingly available in production vehicles and …

Methodology for Determining Crash and Injury Reduction from Emerging Crash Prevention Systems in the U.S.
… safety systems, which aim to prevent or mitigate collisions. These systems are expensive to develop and as a result automakers and regulators are motivated to forecast the potential benefits of a proposed safety system before it is widely deployed in the vehicle fleet. The objective of this …

Reliable Bandwidth Conservative Queue-End Detection and Warning System Using Smart Phone Collaboration Techniques
… road congestion is, the more vulnerable the tail end of the congestion is to rear end collisions. In order to avoid rear end collisions, it is important to know the end location of the traffic jam (i.e. the end of the queue) hence the name, queue-end (q-end) problem. If the exact q-end location is …

System-wide Safety Analysis of a Complex Transportation Facility: Urban Freeway Off-ramps
… of each off-ramp segment. A test for independence was performed to identify if a statistically significant difference existed between type of collision and severity of crashes with respect to ramp geometry and traffic control. Significant geometric and traffic variables were then identified …

Test-driven development of embedded control systems: application in an automotive collision prevention system
… using an automotive safety system for preventing collisions as an example. The basic prerequisite for test-driven development is the availability of an automated testing framework as tests are executed very often. Such testing frameworks have been developed for nearly all programming languages, …

Development and application of a probabilistic risk assessment model for evaluating advanced train control technologies
… of four accident categories: head-on and rear-end collisions, track-fault-related derailments, and collisions with maintenance-of- way equipment. Risk is defined as the aggregate consequences (human casualties) over accident categories. A mathematical model is built, which predicts the …

Analysis Of Various Car-truck Crash Types Based On Ges And Fars Crash Databases Using Mutlinomial And Binary Logit Model
… need to be analyzed further to study the trends for a car-truck crash and develop some countermeasures to lower these crashes. Various types of car-truck crashes are analyzed in this study and the effects of various roadway/environment factors and variables related to driver characteristics …

Analyzing the Impact of Wireless Multi-Hop Networking On Vehicular Safety
… a traffic stream to plan well in advance against rear end collisions which could lead to string instability. We also proposed one such proactive method of planning - and that is by controlling the headway time. Through extensive simulations, we obtained results for vehicle safety when some …

Empirical verification of modeled queue lengths
… vehicles from the through-traffic stream. This tends to increase capacity by adding another lane to the approaches of an intersection and also improves safety and reduces delay. Capacity, delay and operational issues are usually related to a single shared lane between left-turning vehicles and …

Analysis of crash and survey data to identify young drivers' distractions in Kansas
… in one of the three most common crash types: rear-end, angular, and single-vehicle crashes. Furthermore, ordered logistic modeling was used to analyze the crash data to identify the odds of more severe injuries for teenage and young-adult distracted drivers and their passengers involved in …

Reliable Neighborcast Protocol for Vehicular Ad hoc Networks
… using RNP in conjunction with sensors to avoid rear-end collisions. We propose a simple set of rules for using RNP with sensors to automatically maintain a safe following distance, provide warnings of emergency situations, and negotiate the safe deceleration rates among nearby communicating …

An Investigation of the Effectiveness of A Strobe Light As An Imminent Rear Warning Signal
… warn distracted drivers of an unexpected rear end conflict. This "proof of concept study" used a 2 x 2 between-subjects design using thirty-three subjects (16 subjects in the strobe condition, 17 subjects in the no strobe condition) who were divided into two age groups: younger (25-35) and …
