This paper proposes a technique for unwanted lane departure detection. Initially, lane boundaries are detected using a combination of the edge distribution function and a modified Hough transform. In the tracking stage, a linear-parabolic lane model is used: in the near vision field, a linear model is used to obtain robust information about lane orientation; in the far field, a quadratic functi...
Robustly extracting the features of lane markings under different lighting and weather conditions such as shadows, glows, sunset and night is the a key technology of the lane departure warning system (LDWS). In this paper, we propose a robust lane marking feature extraction method. By useing the characteristics of the lane marking to detect candidate areas. The final lane marking features are e...
In this paper, the lane-changing time is considered in the cellular automata models for traffic flow. The lower the velocity of a vehicle, the longer the lane-changing time. The simulations are carried out in the two-lane system and the on-ramp system. When the lane-changing time is taken into account, the maximum flux per lane is reduced in the twolane system compared with the original two-lan...
in this paper we propose a method for solving some well-known classes of lane-emden type equations which are nonlinear ordinary differential equations on the semi-in nite domain. the proposed approach is based on an unsupervised combined arti cial neural networks (ucann) method. firstly, the trial solutions of the differential equations are written in the form of feed-forward neural networks co...
است. با توجه به نقش اساسی عیارحد کارخانه بر روی اقتصاد عملیات، انتخاب بهینه این عیار اهمیت زیادی دارد. یکی از روش های رایج برای تعیین عیارحد بهینه کارخانه استفاده از مدل lane است. این مدل یک مدل پژوهش عملیاتی است که تابع هدف آن بیشینه سازی تفاضل نقدینگی و هزینه فرصت بوده، و محدودیت های وظیفه ای آن ظرفیت معدن کاری، ظرفیت کارخانه فرآوری و ظرفیت بازار (تقاضا) می باشد. با توجه به رابطه بین متغیرها،...

The Mobility control module managesthis relationship by constantly updating the list of Lane Segments for a particular Lane Element based on real-timesensing of the lane position and curvature Intelligent Control of Mobility Systems 249 Right Turnat3-wayIntersectionOwn Vehicle’s Path
Lane line detection plays an important role in vehicle autonomous driving, however non lane line markings and vehicle shadows seriously influence lane line detection results. In this paper, we propose a new lane line segmentation and detection algorithm based on inverse perspective mapping (IPM). Firstly, by using the restriction of the consistent lane line width after IPM, we segment the lane ...
در سال های اخیر مطالعه و تحقیق درباره ی معادلات دیفرانسیل مرتبه دوم غیرخطی منفرد مورد توجه بسیاری از ریاضیدانان و فیزیک دانان قرار گرفته است. دسته ای از این معادلات، معادلات lane-emden می باشند که شکل کلی آن ها به صورت زیر آمده است. که در آن تابعی مجهول، a و b اعداد ثابت، تابعی پیوسته و حقیقی مقدار و تابعی که روی بازه [0,1] مشتق پذیر است. یک روش عددی برای حل معادلات lane-emden منفرد با شر...

The proposed approach is based on an Unsupervised Combined Articial Neural Networks (UCANN) method. Firstly, The trial solutions of the differential equations are written in the form of feed-forward neural networks cont...
This paper studies a technique for combining vision and inertial measurement unit (IMU) data to increase the reliability of lane departure warning systems. In this technique, 2 nd order polynomials are used to model the likelihood area of the location of the lane marking position in the image as well as the lane itself. An IMU is used to predict the drift of these polynomials and the estimated ...
