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...
and reference the set of actual center-of-lane paths (Lane Segments). 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 detection is one of the core functions in autonomous driving and has aroused widespread attention recently. The networks to segment lane instances, especially with bad appearance, must be able explore distribution properties. Most existing methods tend resort CNN-based techniques. A few have a try on incorporating recent adorable, seq2seq Transformer [1]. However, their innate drawbacks we...
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 ...
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 ...
IN T R O D U C T IO N A passing lane is an added lane provided in one or both directions of travel on a conventional tw o-lane highw ay to im prove passing oppo r tunities. T his definition includes passing lanes in level or rolling terra in , clim bing lanes on grades, and short four-lane sections. T he length of the added lane can vary from 1,000 feet as m uch as 3 miles. Figure 1 illustrate...
69 INTRODUCTION The success of operating a drive-thru facility depends on queues and waiting times experienced by customers. Drivethru facilities are required to provide queuing areas that can hold the expected maximum queue length. Rates of arrivals and service times affect the required queuing areas for drive-thru facilities. Gattis recommended queuing areas for drive-thru facilities located ...
است. با توجه به نقش اساسی عیارحد کارخانه بر روی اقتصاد عملیات، انتخاب بهینه این عیار اهمیت زیادی دارد. یکی از روشهای رایج برای تعیین عیارحد بهینه کارخانه استفاده از مدل Lane است. این مدل یک مدل پژوهش عملیاتی است که تابع هدف آن بیشینهسازی تفاضل نقدینگی و هزینه فرصت بوده، و محدودیتهای وظیفهای آن ظرفیت معدنکاری، ظرفیت کارخانه فرآوری و ظرفیت بازار (تقاضا) میباشد. با توجه به رابطه بین متغیرها،...
