Organic-inorganic heterojunction was fabricated by inserting an interlayer having with three different thicknesses on the p-Si substrate. The current voltage (I–V) data of different samples were measured both under the dark and solar simulator at 300K. The photosensing properties of devices were analyzed as a function of incident light intensity via I–V data by considering the influence of different...
As a vehicle proceeds on urban road that includes possible street players such as pedestrian, vehicles, traffic signs, traffic lights, or crosswalks, we can mention about holistic risk caused by dynamic behavior of each items moving along stochastic directions. In the numerous studies, traditional risk estimation methods have been devoted to utilize traffic agents, which have not resulted in effective...
Rural and secondary roads inherently exhibit road curves and turns. This study aims to predict the risk associated with rural road curves exploiting major curve features such as curvature, slope type, and direction. The images acquired by rear and front cameras are utilized to capture the underlined features. Slope type is obtained by two-view images while direction and curvature are estimated by...
In this research, the aim is to come up with an algorithm determining most appropriate variables of CAN (Controller Area Network) bus data for Aggressive/Calm Driving detection problem. This study assists drivers to take attention their Aggressive/Calm Driving habits on steering wheel. System complexity increases as involving all the variables in the problem. Therefore we can get cost efficiency by...
In this study, our goal is to develop an algorithm for selecting most appropriate attributes of CAN (Controller Area Network) bus data in association with Uphill/Downhill road detection problem. In turn, drivers are made aware of Uphill/Downhill situations on steering wheel. In a sense, drivers are enabled to have optimal driving performance for roads at different slopes. Initially, the system collects...
In this paper, we propose a new model for 3-car interactive risky behavior of vehicles travelling in front and behind of a driver (overtaken) car. Following distance of vehicles moving in front and at rear end of the car in question plays an important role for overtaking scenario. Moreover, the distance between the car in front and the vehicle following it should be sufficiently long for preventing...
Here, we describe a method that detects vehicle(s) approaching from behind to a commuting car in the lane in which both are travelling. This research contributes to the development of driver assistance systems by means of informing them about the approaching traffic from behind and warn the drivers in case they are drowsy or not alert and the driving conditions are hazardous. We use the image pairs...
