To study the behavior of expressway driver’s lane change in a foggy environment, vision is adopted as index for assessing behavior. The normalization theory introduced to analyze intention changing lanes. Using statistical examination results gaze zones, this paper has analyzed and glance features driver during Based on driving condition lanes game elaborate strategy equilibrium decision-making...
The collection of fog water is a simple and sustainable technology to obtain fresh water for afforestation, gardening, and as a drinking water source for human and animal consumption. In regions where fresh water is sparse and fog frequently occurs, it is feasible to set up a passive mesh system for fog water collection. The mesh is directly exposed to the atmosphere, and the foggy air is pushe...
In Intelligent Transportation Systems new applications based on cooperative approach are being created. These applications are characterized by the real time reconstruction of the driver environment used in combination of on-board sensors and cooperative system information. In this paper, we propose a traffic modeling and 802.11p access categories mapping of three main ITS services: warning to ...
Providing a suitable and efficient representation of a driver’s perspective is a way to reduce traffic accidents. In this paper, we first introduce a driver-centered AR (augmented-reality) HUD (head-up-display) system that superimposes augmented virtual objects onto a real scene under all types of driving situations including unfavorable weather (such as rainy, foggy, overcast, and snowy) condi...
Drivers in fog tend to maintain short headways, but the reasons behind this phenomenon are not well understood. This study evaluated the effect of headway on lateral control and feeling of risk in both foggy and clear conditions. Twenty-seven participants completed four sessions in a driving simulator: clear automated (CA), clear manual (CM), fog automated (FA) and fog manual (FM). In CM and FM...
Images captured in foggy weather conditions get highly degraded due to suffering from poor contrast and loss of color characteristics. This paper presents a contrast enhancement algorithm for such degraded color images. To restore both contrast and color we propose following four steps: 1) RGB component of the input image is converted into Hue Intensity Saturation (HIS) components; 2) Applying ...
Topic models (e.g., pLSA, LDA, SLDA) have been widely used for segmenting imagery. These models are confined to crisp segmentation. Yet, there are many images in which some regions cannot be assigned a crisp label (e.g., transition regions between a foggy sky and the ground or between sand and water at a beach). In these cases, a visual word is best represented with partial memberships across m...
