This paper describes a novel lane detection algorithm for visual traffic surveillance applications under the auspice of intelligent transportation systems. Traditional lane detection methods for vehicle navigation typically use spatial masks to isolate instantaneous lane information from on-vehicle camera images. When surveillance is concerned, complete lane and multiple lane information is ess...
Driving in the early morning is associated with increased accident risk affecting not only professional drivers but also those who commute to work. The present study used a driving simulator to investigate the effects of driving home from a night shift. Ten shift workers participated after a normal night shift and after a normal night sleep. The results showed that driving home from the night s...
In this report a new designed real-time lane detection algorithm based on monocular vision and inertial measurement unit (IMU) is explained and evaluated. The acquired image from the camera is undergoing an inverse perspective mapping to create a bird-view perspective of the road. Local maxima in this image determine the lane-markers. Faulty local maxima are removed and constrained line fitting...
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
Figure 8: The initialization of the algorithm is done by detection of portions of straight lines of common orientation (top left). Within the search zone predicted using current the current lane markers parameters (top right), a precise model-based localization of lane markers points is performed (bottom). 25 Localize within the search zone the center of lane markers, using a model of the image...
Vehicle control can be described with lateral and longitudinal measures. The Standard Deviation of Lateral Position (SDLP) is probably the most common measure to reflect control. Indices such as mean (MLP) Time-to-Line Crossing (TLC) have also been used describe driver behaviour. Even though all these measures demonstrated their value, in some specific cases, may indicate that behaviour deterio...
A Steer-By-Wire (SBW) control scheme is proposed for enhancing the lateral stability and handling capability of a super lightweight vehicle by using the energy optimal control method. Tire dissipation power and virtual power, which is the product of yaw moment and the deviation of actual yaw rate from the target yaw rate, were selected as performance measures to be minimized. The SBW control sc...
system evaluations were performed on 48 center pivots in different parts of saudi arabia. these systems, located on different farms in four different regions of the country, namely: riyadh, jouf, qassim and eastern regions, were evaluated to study the effect of lateral configuration on water application uniformity as regards the original vs. modified laterals. lateral configuration modification...
Purpose The trajectory of a vehicle is comprehensively affected by the interactions between the vehicle, the driving behavior, and the road environment. High-risk driving behaviors and accident-prone road sections can be identified based on the relationship between the trajectory and road geometry. Previous related studies mostly focused on the trajectory deviation at a few points on the road, ...
