The percentage of pedestrian deaths in traffic accidents is on the rise in Japan. In recent years, there have been calls for measures to be introduced to protect vulnerable road users such as pedestrians and cyclists. In this study, a method to detect and track pedestrians using an in-vehicle camera is presented. We improve the technology of detecting pedestrians by using the highly accurate im...

Pedestrian protection systems, both active and passive systems, are being introduced in the EU and Japan to comply with regulatory requirements. Their designs are specific and, in general, reflect an accident scenario of the pedestrian being struck on the side by a vehicle traveling at a maximum travel speed of 40 kph. The present study is an effort to quantify the effects of pedestrian reactio...

The approach of an object can be monitored from its optic flow. More specifically, it has been postulated that time-to-collision at constant velocity is perceived by relating visual angle theta to its rate of change theta, time-to-collision being theta/theta. This hypothesis is reappraised, and an alternative based on the parameters theta and angular acceleration theta is proposed. The expressi...

With the rapid explosion of population, usage of motor vehicle is also increasing. This has been causing a serious issue in road safety for the past few decades. Road pedestrian injuries and death rate is also rising day by day. The research on traffic accidents shows a clear concentration of crashes happening in Black Spots. Accident black spots include steep slopes, a hidden junction, sharp c...

Road Traffic Accidents are considered to be one of the leading causes of death and injuries worldwide. In recent years as many as 50 million people are injured or disabled by road traffic accidents every year. Road traffic accidents impose a burden on countries by costing up to 4% of their Gross National Product. Therefore, the purpose of this study was to determine the prevalence of injuries r...

BACKGROUND/AIMS Older people are over-represented in pedestrian fatalities, and it has been suggested that the presence of cognitive impairment or dementia in these individuals may contribute to their accidents. Using neuropathological methods, we aimed to compare the prevalence of dementia pathology in fatally injured older pedestrians with similarly aged ambulatory subjects who died from othe...

STUDY OBJECTIVE To examine the trends in childhood head injury mortality in Scotland between 1986 and 1995. DESIGN Analysis of routine mortality data from the registrar general for Scotland. SETTING Scotland, UK. SUBJECTS Children aged 0-14 years. MAIN RESULTS A total of 290 children in Scotland died as a result of a head injury between 1986 and 1995. While there was a significant decli...

Objective: Based on the field data analyses, lower extremities are the most frequently injured body region in vehicle-to-pedestrian crashes, and their injury risk is highly related to human characteristics, such as stature, BMI and age. However, the current pedestrian models only focused on the mid-size male subjects. Therefore, the objective of this work is to develop a method to morph the mid...

PURPOSE Traffic injuries are among the leading causes of mortality and morbidity worldwide. Pedestrians have been considered as a high-risk group among road users, especially in middle- or low-income communities. This study attempted to determine the burden of pedestrians' fatalities in Fars, the southern province of Iran using years of life lost (YLL) approach. METHODS The data used in this ...
