This analysis examines how the age of the vehicle at the time of the crash and the vehicle’s model year are correlated with the injury outcome of the driver of a passenger vehicle involved in a fatal crash. A multivariate logistic regression model was constructed to model the relationship between injury outcome (fatally injured versus survived) of the driver and the independent variables vehicl...

The microscopic simulation of traffic operations at a toll plaza entails the detailed understanding of the driver behavior. The lane selection behavior of the driver involves complex inter-vehicle dynamics. This study involves the development of a new methodology for the microscopic simulation of toll plaza operations. Different driver dynamics such as the lane selection probability based on th...

The authors present a cyber-physical systems study on the estimation of driver behavior in autonomous vehicles and vehicle safety systems. Extending upon previous work, the approach described is suitable for the long term estimation and tracking of autonomous vehicle behavior. The proposed system makes use of a previously defined Hybrid State System and Hidden Markov Model (HSS+HMM) system whic...

In today’s world, the effectiveness of electronic active control systems in stabilizing a vehicle’s motion has been recognized; thus, numerous active control systems have been developed to realize effective braking torque and traction control and have been incorporated in mass-produced vehicles. However, an effective active control system for steering is not yet available. Active front steering...

Higher levels of road vehicle automation pose a regulatory challenge in the U.S. At the national level, the National Highway Traffic Safety Administration (NHTSA) has been responsible for ensuring vehicle safety through the mandatory Federal Motor Vehicle Safety Standards (FMVSS) and the voluntary New Car Assessment Program (NCAP). Although NHTSA typically regulates the technology aspects of ve...

The Vehicle in the Loop test setup has been developed for the safe, reproducible and resources-saving test of driver assistance functions for support in critical traffic situations. This setup combines the advantages of driving simulators and a real test vehicle by incorporating it into a traffic simulation. While driving, the synthetic outside traffic is visualized to the driver realistically ...

This paper presents a new concept and an experimental validation of a real-time driver assistance system involving multiple sensors and actuators monitoring an area around the vehicle and conveying alerts to the driver. The proposed system, dubbed the driving assistant, detects the presence of obstacles within the monitored area and alerts the driver via a combination of tactile, audio, and vis...

The objective of this paper is to bring to you a technology that helps those handicapped who don’t have healthy hands to run a vehicle by giving the voice commands. In this the driver need not use the steering instead his head. This vehicle is only for those handicapped those who can nod head well. Four switches are interfaced over the neck of the driver, and the vehicle can be controlled by th...

Computer Vision can provide a great deal of assistance to Intelligent Vehicles. In this paper an Advanced Driver Assistance Systems for Vehicle Detection is presented. A geometric model of the vehicle is defined where its energy function includes information of the shape and symmetry of the vehicle and the shadow it produces. A genetic algorithm finds the optimum parameter values. As the algori...

Driver drowsiness is a major, though elusive, cause of traffic crashes. As part of its IVHS/human factors program, NHTSA is supporting research to develop in-vehicle systems . to continuously monitor driver alertness and performance. Scientific support for the feasibility of this countermeasure concept is provided by research showing that: l Drowsy drivers typically do not “drop off’ instantane...
