In certain application areas, such as those related to decision support or multimedia data, users wish to ask so-called top N and bottom N queries; these are queries that request a certain number of answers (N) having the highest or lowest values for some attribute, expression, or function. For example, rather than nding all publications on a certain topic, a researcher may want to retrieve the...

Road region recognition is a main feature that is gaining increasing attention from intellectuals because it helps autonomous vehicle to achieve a successful navigation without accident. However, different techniques based on camera sensor have been used by various researchers and outstanding results have been achieved. Despite their success, environmental noise like shadow leads to inaccurate ...

This paper presents a deterministic approach for performance assessment of different province’s road safety level at Iran. A data envelopment analysis (DEA) model considering undesirable input and output indices and a multivariate statistical method, principle component analysis (PCA) are used in this paper, while previous studies do not use composite PCA-DEA method and undesirable input and ou...

Clock drawing is recommended by medical and transportation authorities as a screening test for unsafe drivers. The objective of the present study was to assess the usefulness of different clock drawing systems as screening measures of driving performance in 122 healthy and cognitively impaired older drivers. Clock drawing was measured using four different scoring systems. Driving outcomes inclu...

In this work, we introduce an application of computer graphics to the validation of an automotive illumination system in dynamics conditions. We propose the creation of a virtual road, where it is possible to “drive” the vehicle for different kinds of tracks and to study the performance of the headlights in dynamics conditions on the road. The projection of the light is directly affected by the...

Antilock braking system (ABS) stops a vehicle wheel without locking while decreasing the stopping distance. Here we use fuzzy logic to detect the road conditions. Vehicle dynamics and braking systems is complex and proposed controller in different road detected states. They behave strongly non-linear which causes difficulties in developing a classical controller for ABS. Fuzzy logic, however fa...

Driver fatigue remains a significant cause of motor-vehicle accidents worldwide. New technologies are increasingly utilised to improve road safety, but there are no effective on-road measures for fatigue. While simulated driving tasks are sensitive, and simple performance tasks have been used in industrial fatigue management systems (FMS) to quantify risk, little is known about the relationship...

A study of drivers aged 50-90 was carried out to assess which, if any, of a range of measures were useful in predicting on-road performance. The study had three phases. In Phase One almost 2000 drivers completed an extensive self-report questionnaire, the Aging Driver Questionnaire, or ADQ. In the ADQ they described their personal and driving history, their driving behaviour and their attitudes...

Coverage problem in wireless sensor networks measures how well a region or parts of it is sensed by the deployed sensors. Definition of coverage metric depends on its applications for which sensors are deployed. In this paper, we introduce a new quality control metric/measure called road coverage. It will be used for measuring efficiency of a sensor network, which is deployed for tracking movin...
