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...

An analytical investigation of a half-car model including passenger dynamics, subjected to random road disturbances is performed, and the advantage of active over conventional passive suspension systems are examined. Two diierent performance indices for optimal controller design are proposed. The performance index is a quantiication of both ride comfort and road handling. Due to practical limit...

The road network detection is an emerging area in information extraction from high-resolution satellite images (HRSI). The proposed work in this paper consists of three steps: Pre-filtering, connected component-based operations, and removal of unwanted non-road pixels using morphological operations. The proposed algorithm is experimented on various satellite images and the performance of the sy...

The road surveillance based on wireless sensor network nowadays has received great attention and its application has been extensively used in practice. In this application, when the invasion target moves from road entrance to system protection points in road network, the nodes in wireless sensor network could detect the target timely and give an alarm before the target reaches the protection po...

In order to achieve significant improvements in road safety at the national level, there is a need for a systematic approach to road safety management with clear responsibilities and accountability. In this paper – after a review of the literature on guidelines, recommendations and research findings – twelve essential elements of such a systematic approach are pointed out, and corresponding rel...

BACKGROUND This study was designed to determine whether an education program consisting of classroom and on-road training could enhance driving performance. METHODS This randomized controlled trial with blinded endpoint assessment enrolled 126 community-living drivers 70 years old or older who were recruited from clinic and community sources. Treatment assignment was concealed until eligibili...

This paper presents Direction based Hazard Routing Protocol (DHRP) for disseminating information about fixed road hazards such as road blocks, tree fall, boulders on road, snow pile up, landslide, road maintenance work and other obstacles to the vehicles approaching the hazardous location. The proposed work focuses on dissemination of hazard messages on highways with sparse traffic. The vehicle...
