In the following, the main concepts of a road lane model are presented that keeps track of an arbitrary number of lane borders. Information from an existing lane detection device, a gyrosensor, and map data are merged and filtered to create a road model with a desired number of road lines. The model is based on clothoids and continuously provides positions, angles, and curvatures of the border ...

JT00127539 Document complet disponible sur OLIS dans son format d'origine Complete document available on OLIS in its original format CEMT/CM(2002)11/FINAL 2 Although still far from satisfactory, more progress has been made on road safety on motorways and urban roads over the past 20 years than on country roads. Rural roads are defined as roads outside urban areas that are not motorways or unpav...

Applications of camera vision, such as lane departure warning systems, are limited by the quality of the frame image and the information contained within each frame. One common feature extraction technique in image processing is the use of the Hough transform, which can be used to extract lines from an image. The detected lane marking lines are used in the interpolation of a 2 nd order polynomi...

Headway or inter-arrival time of vehicles is an important parameter in traffic flow, especially in urban roads, since this is one of the main parameters to determine the minimum (safe) gap between vehicles and the capacity. The studies done on headway analysis have mostly concentrated on homogeneous traffic where the flow follows lane discipline. This ideal situation does not exist on Indian ur...

We adapt the Multi-lane Spatial Logic MLSL, introduced in [1] for proving the safety (collision freedom) of traffic manoeuvres on multi-lane motorways, where all cars drive in one direction, to the setting of country roads with two-way traffic. To this end, we need suitably refined sensor functions and length measurement in MLSL. Our main contribution is to show that also here we can separate t...

We present a system for detecting and tracking the lanes of high-speed roads, in order to warn the driver of accidental lane departures. The proposed method introduces a novel variant of the classic Hough transform, better equipped to detect and locate linear road markings with a common vanishing point. This is combined with a simple model of the lane and an Extended Kalman Filter to make detec...

Lane detection in urban environments is a challenging task. That is mainly due to the non existence of unique models, poor quality of lane markings due to wear, occlusions due to the presence of traffic and complex road geometry. In this work we present a novel lane detection and tracking algorithm for urban road scenarios based on weak models, which is implemented by a particle filter. The alg...

A lane detection algorithm for complex environment was proposed. It was concerned on selecting candidate lane region by object segmentation. Then redundancy edges were extracted by Sobel operator. Furthermore, candidate lane markers were obtained by threshold selection from the edges. Finally lane markers were detected by piecewise fitting. The proposed algorithm was simulated in MATLAB. Experi...
