An analytical investigation of a half-car model with passenger dynamics, subjected to random road disturbance, is performed. Two diierent methods of deening the performance index for optimal controller design are proposed. Nondeterministic inputs are applied to simulate the road surface conditions more realistically. Results obtained illustrate that using an optimal state-feedback controller, w...

This study assessed the degree to which hazardous vignettes are perceived as dangerous and realistic by car drivers and motorcycle riders (Exp. 1) and whether riders could be distinguished from drivers on their performance in a commercial motorcycle simulator during safe and hazardous riding situations using the same hazards (Exp. 2). In Experiment 1, car drivers and motorcyclists received a qu...

A half-car model with four DOF was established to simulate the system. On the basis of this model, Selfadapt Parameters Fuzzy-PID control method of the active suspension system is described. In such a model, vehicle speed, vehicle body vertical acceleration, suspension dynamic deflection, the body vertical acceleration and suspension dynamic deflection integrated feedback were used respectively...

This research elucidates the trip pattern of the low-density residential zone in a semi-urban industrial cluster of southwestern Nigeria. These sets of dwellers are often times neglected in the transportation planning process with the view that it is not a residential zone. Domiciliary information gathering procedure was employed in the analysis with 0.82 return rates. It was backed up with the...

This paper presents a method for learning an And-Or model to represent context and occlusion for car detection and viewpoint estimation. The learned And-Or model represents car-to-car context and occlusion configurations at three levels: (i) spatially-aligned cars, (ii) single car under different occlusion configurations, and (iii) a small number of parts. The And-Or model embeds a grammar for ...
