BACKGROUND The three-wheeler Qing-qi and Compressed Natural Gas (CNG) auto-rickshaws were introduced in Karachi to meet the transportation demand of the growing population. These vehicles have directly or indirectly been implicated in a number of road traffic violations as well as road accidents. This study aims to describe the crash characteristics and injury patterns for Qing-qi rickshaw occu...

44 Attention to user behavior and preferences has been a helpful tool in improving road safety and 45 accident prevention in recent years. At the same time, there remain some important areas of road 46 safety and accident prevention for which user preferences have not been explored. For instance, 47 so far, road safety research has not addressed pedestrian and vulnerable user preferences with 4...

The assessment of the safety of road crossing facilities in urban scenarios can be supported by means of advanced computer-based simulations. Integrated models considering the vehicular and pedestrian traffic, and their interactions, still lack empirical evidences about the heterogeneous features of pedestrians, with particular reference to age-driven crossing behaviour. Elderly pedestrians are...

INTRODUCTION Road traffic crashes constitute a considerable public health burden and represent the eighth leading cause of death and tenth leading cause of disability adjusted life years (DALYs) globally. However, very little is known about the extent, causes and impact of crashes in low- and middle-income countries including those in the Pacific. This lack of data is particularly true for the ...

This research proposed a pedestrian detection system in an outdoor scene by a pin-hole camera with field-programmable gate array. We used two different feature descriptors included histograms of oriented gradients and local weighted pattern which were descripted the shape and textural information for the image feature of pedestrians. Semi-supervised learning with linear support vector machine w...

Both humans and the sensors on an autonomous vehicle have limited sensing capabilities. When these limitations coincide with scenarios involving vulnerable road users, it becomes important to account for these limitations in the motion planner. For the scenario of an occluded pedestrian crosswalk, the speed of the approaching vehicle should be a function of the amount of uncertainty on the road...

Recently, the focus of safety systems for intelligent vehicles has been on researching and developing Advanced Driver Assistance Systems (ADAS). Most efforts have been concentrated at the driver, not taking into account the protection of the most vulnerable road users. This paper describes a pedestrian detection algorithm based on stereo vision. The use of visual information is a promising appr...

1 Pedestrians and cyclists are vulnerable road users and despite their limited presence in traffic events, these 2 two groups have the most collisions resulting in injuries and fatalities. Due to problems regarding data 3 collection for pedestrians and cyclists, there is a shortcoming in the field of road safety with regards to the 4 availability and quality of data for non-motorized modes.
