OBJECTIVE To investigate comparative road user crash and fatality rates in Japan between 2000 and 2010 in the elderly and young. METHODS Data from the Japan Ministry of Health, Labor and Welfare Vital Statistics Database and the Institute for Traffic Accident Research and Data Analysis were used to calculate crash rates by age group, vehicle, and license category. RESULTS Fatal crash rates ...

This paper presents a monocular visual odometry algorithm that incorporates a wheeled vehicle model for ground vehicles. The main innovation of this algorithm is to use the single-track bicycle model to interpret the relationship between the yaw rate and side slip angle, which are the two most important parameters that describe the motion of a wheeled vehicle. Additionally, the pitch angle is a...

Like computer vision before, remote sensing has been radically changed by the introduction of deep learning and, more notably, Convolution Neural Networks. Land cover classification, object detection and scene understanding in aerial images rely more and more on deep networks to achieve new state-of-the-art results. Recent architectures such as Fully Convolutional Networks can even produce pixe...

This paper will document the development of the Convoy Active Safety Technology (CAST) program, which was created to design a low cost, optionally manned vehicle (OMV) solution for tactical wheeled vehicle (TWV) fleet. This paper will describe the approach taken to integrate low cost sensors for understanding the environment sufficiently to accomplish convoy missions. This paper will also discu...

Wheelchair racing is an important modality in the rehabilitation of people with mobility impairments; thus, it plays a significant role in the lives of many wheelchair users. This paper presents simple roll stability analyses for three- and four-wheeled rider/racing wheelchair systems during turning maneuvers. The results suggest that three-wheeled systems may be less stable than four-wheeled s...

Vehicle models whose propulsion system is based on electric motors are increasing in number within the automobile industry. They will soon become a reliable alternative to vehicles with conventional propulsion systems. The main advantages of this type of vehicles are the non-emission of polluting gases and noise and the effectiveness of electric motors compared to combustion engines. Some of th...
