The Anti-lock braking system (ABS) is an active safety device in road vehicles, which during hard braking maximizes the braking force between the tyre and the road irrespective of the road conditions. This is accomplished by regulating the wheel slip around its optimum value. Due to the high non-linearity of the tyre and road interaction, and uncertainties from vehicle dynamics, a standard PID ...

ABSTRACT Little research has been conducted to understand the difference in driving performance between younger-old adults (60-75 years) and older-old adults (76+ years), or simply younger olds and older olds. The main objective of this study was to determine if a minimal increase in road light level (luminance) differently affects the performance of these two distinct age groups. Older adults...

This study examined the relationship of neuropsychological and on-road driving evaluations among adults with acquired brain injury (ABI), and the extent to which that relationship is moderated by awareness of deficit. Participants were 62 pairs of adults with ABI and significant-other informants and 40 healthy controls (N = 102). Adults with ABI and controls completed neuropsychological and on-...

Vision-based autonomous driving requires classifying each pixel as corresponding to road or not, which can be addressed using semantic segmentation. Semantic segmentation works well when used with a fully supervised model, but in practice, the required work of creating pixel-wise annotations is very expensive. Although weakly supervised segmentation addresses this issue, most methods are not de...

Much e ort has been devoted to Japanese morphological analysis (Matsumoto et al 1996; Nagata 1994; Papageorgiou 1994; Yamamoto & Masuyama 1997). The general performances of many of them are quite good. For the purpose of processing complex terms and keywords, however, they have some problems and limitations. Firstly, most general purpose morphological analysers do not segment complex words cons...

We present new implementations of heuristic algorithms for the solution of the multiobjective shortest path problem, using a new graph structure specifically suited for large scale road networks. We enhance the heuristics with further optimizations and experimentally evaluate the performance of our enhanced implementation on real world road networks achieving 10 times better performance with re...

OBJECTIVE To identify variables that best predict a team's decision of driving ability in stroke patients from a predriving assessment. DESIGN Retrospective study of a 2-year predriving evaluation. SETTING Belgian Institute for Road Safety. PARTICIPANTS One hundred four patients with sequelae of first stroke. INTERVENTIONS Predriving assessments and road test. MAIN OUTCOME MEASURES Th...

The focus of this study is on the problems connected with road passenger transportation process performance measurement system development. Thus, the main definitions and briefly literature overview in the analyzed research area are given. Later, the main classification of road passenger transportation processes’ performance measures are developed. There are presented obtained performance analy...

Abu Dhabi’s government has taken several initiatives to improve the safety of city’s highways, such as reducing traffic accident occurrence, red light violations, and property damage associated with accidents. However, intersections are still many severe accidents, violations. To help authorities pinpoint major contributors deterioration performance signalized junctions, this study employed a n...
