The tire-road friction coefficient is critical to the performance of mobile robots working outdoors. However, it is difficult to measure using commercially available technology sensors. This paper presents a method of estimating the tire-road friction coefficient using a disturbance observer (DO) with compensator; the chassis speed is not needed. In this paper, the torque produced by the tire-r...

Vision based vehicle detection is a critical technology that plays an important role in not only vehicle active safety but also road video surveillance application. Traditional shallow model based vehicle detection algorithm still cannot meet the requirement of accurate vehicle detection in these applications. In this work, a novel deep learning based vehicle detection algorithm with 2D deep be...

We propose a hybrid ITS safety architecture that combines vehicle-to-vehicle communication and vehicle-to-roadside sensor communication. Opposed to dedicated roadside units, which require major investments for purchase, installation and maintenance, roadside wireless sensor and networking technology represents a cost-effective solution and can leverage the deployment of the system as a whole. A...

Usually, vehicles driven under diierent road conditions are subjected to various forces and moments. An uneven input force originating from road surface could be one of the major load aaecting ride comfort or body vibration. In order to investigate the ride and handling characteristics of a tandem axle truck, a three dimensional mathematical model is developed, and the equations of motion for t...

Worldwide, more than 185,000 children under 18 years die from road traffic accidents annually (each four minutes a child death occurred due to road crashes); with most casualties from developing countries. 95% of road traffic fatalities among children occur in developing countries. Many more children are injured, often severely, and suffering from different disabilities. Road accidents cause ex...

INTRODUCTION We examined the accuracy of research participant characterizations of motor vehicle collisions (MVC). METHODS We conducted an emergency department-based prospective study of adults presenting for care after experiencing an MVC. Study participants completed a structured clinical interview that assessed the number of lanes of the road where the collision took place, vehicle type, r...

BACKGROUND Road trauma represents a high proportion of injury-related emergency department presentations. Narrative text recorded in the emergency department could provide useful information to monitor road trauma and to identify crash and injury risk factors by age group. OBJECTIVE To examine the Public Health Real-time Emergency Department Surveillance System (PHREDSS) to identify road user...

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...

This paper presents an approach to visually classifying the high-level geometry of the road ahead of a vehicle as a section with continuous curvature parallel edges or an intersection containing right-angled legs. The default behavior of the system is snake-based tracking of parallel road edges for curvature estimation. A separate process segments the road surface from the background using colo...

Objective: This paper makes a projection of the vehicle ownership rate to the year 2010 and to use this projection to predict road accident deaths in year 2010. The projection served as an indicator for the Malaysian government to achieve a 4 road accident deaths per 10,000 vehicles safety target in year 2010. Method: The study included the prediction of vehicle ownership and the analysis of pa...
