Sensor Integration for Low-Cost Crash Avoidance
… development of sensor integration for low-cost crash avoidance for over-land commercial trucks. The goal of the project was to build and test a system composed of low-cost commercially available sensors arranged on a truck trailer to monitor the environment around the truck. The system combines …

Geomagnetic Compensation for Low-Cost Crash Avoidance Project
… The magnetic sensor is a part of a low-cost crash avoidance system by Stephane Roussel where the magnetic sensor was used to detect cars passing when it was mounted to a test vehicle. However, the magnetic sensor’s output voltage varied when it changed orientation with respect to the Earth’s …

Threat Assessment and Proactive Decision-Making for Crash Avoidance in Autonomous Vehicles
… give an autonomous vehicle enough time to avoid crashes or near crash situations. Most vehicles on roads are human-driven, making it challenging to predict their intentions and movements due to inherent uncertainty in their behaviors. Moreover, different driver behaviors pose different kinds of …

Auditory localization of in-vehicle crash avoidance warnings as a cue to hazard direction
… roadway hazards detected by an in-vehicle crash avoidance warning device. Auditory localization of the warning sound was investigated as a means of indicating hazard locations relative to the vehicle. Four dependent variables were measured— response time, decision time, accuracy, and …

Crash avoidance by electronic stability control on Australian high speed rural roads: an analysis of braking interventions.
… The greatest benefit to Australia is for crashes on high speed rural roads that occur due to a loss of control. An investigation of what variables in the South Australian statewide crash database are associated with high injury severity for vehicle occupants during crashes on high speed …

Examination of Driver Lane Change Behavior and the Potential Effectiveness of Warning Onset Rules for Lane Change or "Side" Crash Avoidance Systems
Lane change or "Side" Crash Avoidance Systems (SCAS) technologies are becoming available to help alleviate the lane change crash problem. They detect lane change crash hazards and warn the driver of the presence of such hazards. This thesis examines driver lane change behavior and evaluates the …

Evaluating the Potential of an Intersection Driver Assistance System to Prevent U.S. Intersection Crashes
Intersection crashes are among the most frequent and lethal crash modes in the United States. Intersection Advanced Driver Assistance Systems (I-ADAS) are an emerging active safety technology which aims to help drivers safely navigate through intersections. One primary function of I-ADAS is to …

Eight Degree of Freedom Vehicle Model with Pitch, Yaw, Tire Control and Sensor Inputs
… modeling and implementation of signal inputs and crash avoidance logic while maintaining accuracy in the physics of the vehicle’s motion. Firstly, the equations of motion for the bodies involved under a reasonable set of assumptions were developed. Next the model was translated to computer code. …

Simulation of Crash Prevention Technology at a No- Passing Zone site
No-passing zone crashes constitute a sizable percentage of the total crashes on two-lane rural roads. A detection and warning system has been devised and implemented at a no-passing zone site on route 114 of Southwest Virginia to address this problem. The warning system aims at deterring drivers …

Methodology for Determining Crash and Injury Reduction from Emerging Crash Prevention Systems in the U.S.
… or mitigate the negative consequences of traffic crashes, automakers are developing active 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 …

Occupant Responses of Relaxed and Braced 5th Percentile Female and 50th Percentile Male Volunteers during Low-Speed Frontal and Frontal-Oblique Sled Tests
The increased prevalence of crash avoidance technologies like autonomous emergency braking necessitates understanding of occupant responses during low-speed frontal pre-crash braking and low-severity crash events. Active human body models (HBMs) have emerged as valuable tools to evaluate occupant …

Prospects for the Collision-Free Car: The Effectiveness of Five Competing Forward Collision Avoidance Systems
… 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 have a great potential for preventing or mitigating rear-end collisions. …

Pedal Misapplication: Past, Present, and Future
… 1. Identify and analyze multiple samples of PM crashes from a variety of data sources using both established and novel methods to gain new insight into the characteristics and frequency of PM crashes. 2. Use the confirmed, real-world PM crash data to develop a custom vehicle dynamics simulation …

Characterizing Bicyclists Behavior in Overtaking Scenarios Over Different Road Infrastructures
Fatal vehicle-bicycle crashes have increased in the United States while cyclist crashes often go unreported. The underreporting of all cyclist crashes results in the overall pre-crash behavior of the cyclists being unknown. What is known is that the most fatal bicycle crash scenario occurs when a …

Development and validation of a driver distraction alert system for highway driving using a truck driving simulator
Driver distraction is one of the major causes of vehicle accidents, injuries, fatalities and economical losses in Canada and across the world. The main objective of this thesis is to develop a real time driver distraction alert system that can generate early warning signals and prevent vehicle …
