present study is an extension of earlier work carried out on two-lane two way roads in the two provinces of pakistan i.e. n-25, n-55 and n-5 regarding the measure of operating speed and development of operating speed prediction models. curved sections of two-lane rural highways are the main location of run-off road accidents. in addition to that the road alignment having combination of geometri...

Maneuvers of a nonholonomic vehicle in a structured dynamic environment are considered. The paper focuses on motion generation and control methods to autonomously perform lane following/changing and parallel parking maneuvers. Lane following/changing involves the tracking of a nominal trajectory in the traac lane, and the generation and tracking of local lane-changing trajectories, for instance...

The lane-tracing algorithm is a reduced-space LR(1) parser generation algorithm. The previous version of lane-tracing algorithm regenerates states involved in reduce/reduce conflict by employing the practical general method. In this paper we describe an alternative lane-tracing approach, which regenerates states based on the lane table method. We discuss the details of this new algorithm, study...

This paper presents a much advanced and efficient lane detection algorithm. The algorithm is based on (ROI) Region of Interest segmentation. In this algorithm images are pre-processed by a top-hat transform for de-noising and enhancing contrast. ROI of a test image is then extracted. For detecting lines in the ROI, Hough transform is used. Estimation of the distance between Hough origin and lan...

In this paper, we analyze the kinematics of the vehicles involved in a lane changing/merging maneuver, and study the conditions under which lane changing/merging crashes can be avoided. That is, given a particular lane change/merge scenario, we calculate the minimum longitudinal spacing which the vehicles involved should initially have so that no collision, of any type, takes place during the m...

In this paper we propose a new lane detection method for expressway lane departure warning. The use of the extended Hough transform and a bird's-eye view image effectively improve the robustness and resolution of lane detection. Hardware cost is reduced by using a rear-view camera from an existing system and by implementing the system on an embedded CPU.

We give a precise description of combed trees in terms of KellyMac Lane graphs. We show that any combed tree is uniquely expressed as an allowable Kelly-Mac Lane graph of a certain shape. Conversely, we show that any such Kelly-Mac Lane graph uniquely defines a combed tree.
