OBJECTIVE To find an association between cognitive-perceptual problems of older drivers and unsafe driving performance during simulated automobile driving in a virtual environment. DESIGN Cross-sectional study. SETTING A driver evaluation clinic in a rehabilitation hospital. PARTICIPANTS Fifty-five drivers aged 65 years or older and 48 drivers in their late twenties to early forties. ME...

This paper aims to investigate a new and intricate behavior of immediate follower during the lane change of leader vehicle. Accordingly, the mentioned situation is a transient state in car following behavior during which the follower vehicle considerably deviates from conventional car following models for a limited time, which is a complex state including lateral and longitudinal movement simul...

Drivers with obstructive sleep apnea syndrome (OSAS) have an increased risk of motor vehicle crashes. Unfortunately, neither clinical nor polysomnographic features allow clinicians to reliably identify high-risk drivers. One potential means of identifying these drivers is with the use of driving simulators. Several investigators have shown that OSAS patients perform worse than healthy control d...

This paper describes the use of ordered probit models to examine the risk of different injury levels sustained under all crash types, two-vehicle crashes, and single-vehicle crashes. The results suggest that pickups and sport utility vehicles are less safe than passenger cars under single-vehicle crash conditions. In two-vehicle crashes, however, these vehicle types are associated with less sev...

We study the dependence of risk on vehicle type and especially on vehicle model. Here, risk is measured by the number of driver fatalities per year per million vehicles registered. We analyze both the risk to the drivers of each vehicle model and the risk the vehicle model imposes on drivers of other vehicles with which it crashes. The "combined risk" associated with each vehicle model is simpl...

Successful modeling and simulation of driver behavior is important for the current industrial thrust of computer-based vehicle development. The main contribution of this paper is the development of an adaptive lateral preview human driver model. This driver model template has a few parameters that can be adjusted to simulate steering actions of human drivers with different driving styles. In ot...

Previous studies have revealed that aggressive and reckless driving can largely affect the occurrence severity of road crashes. There could be intentional unsafe acts, which significantly safety all users. The size vehicle type driver might such acts. This study evaluates behaviors committed by drivers based on using data collected from video recordings at two intersections in Doha, Qatar. obse...

INTRODUCTION In many low income countries, commercial vehicles are the major source of motorized transport. Drivers of such vehicles may be an important focus for road safety efforts. AIMS An estimation of the percentage of motor vehicle related injuries that involved commercial vehicles in Ghana was sought. The knowledge, attitude, and practices of commercial drivers with regards to road saf...
