Sag sections are freeway where the gradient varies significantly from top to bottom. Due their special geometric characteristics, sag often bottlenecks in motorway networks. However, we still unclear about underlying mechanisms of traffic congestion two-lane sections. Based on actual lane change experience, a lattice flow model at considering empirical rate is proposed. The developed reveal evo...

The entrances of tunnels are generally considered to be accident-prone locations, and accidents related this area mainly include rear-end sideswipe crashes, which also associated with lane-changing behaviours. Despite the extensive literature on safety lane-changing, little attention has been given behaviours in front tunnel entrance. To end, study investigates contributing factors potential ri...

This paper presents a way to e ciently use lane detection techniques known from driver assistance systems to assist in obstacle detection for autonomous trains. On the one hand, there are several properties that can be exploited to improve conventional lane detection algorithms when used for railway applications. The heavily changing visual appearance of the tracks is compensated by very e ecti...

As traffic demand on road networks steadily increases every year, the need for alleviation of global congestion arises. Our contribution lies in assisting of traffic engineers and policy makers who are faced with the problem of controlling the traffic flows. In this paper, we explore the usefulness of cellular automata to traffic flow modeling. We extend some of the existing CA models to captur...

The availability of active safety systems, such as Lane Departure Warning (LDW), has recently been added as a rating factor in the U.S. New Car Assessment Program (NCAP). The objective of this study is to determine the relevance of the NCAP LDW confirmation test to real-world road departure crashes. This study is based on data collected as part of supplemental crash reconstructions performed on...

From common driving experiences, car drivers are unwilling to follow heavy vehicles owing to speed and visibility obstructions, and most of them choose to change lanes to mitigate such obstructions. In literature, however, the impact of heavy vehicles on lane-changing decisions of following car drivers has rarely been investigated. In this study, a methodology for shedding light on such impact ...
