This paper presents an analysis of rearward gap acceptance characteristics of drivers of large trucks in highway lane change scenarios. The range between the vehicles was inferred from camera images using the estimated lane width obtained from the lane tracking camera as the reference. Six-hundred lane change events were acquired from a large-scale naturalistic driving data set. The kinematic v...

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...

A framework for integrated driving behavior modeling, based on the concepts of short-term goal and short-term plan is proposed. Drivers are assumed to conceive and perform short-term plans in order to accomplish short-term goals. This behavioral framework captures drivers' planning capabilities and allows decisions to be based on anticipated future conditions. An integrated driving behavior mod...

1 I n t r o d u c t i o n Automated highway systems (AHS) offer the potential of significant improvements in traffic flow volume and stability, as well as safety, when compared with current manually-controlled highway driving (Shladover, 1991). Implementation of AHS requires completely automated lateral and longitudinal control of vehicle motions as well as coordination of the maneuvers of diff...

Resolving traffic congestion caused by sudden events (e.g., an accident, lane closed due to construction) on the freeway has always been a problem that is challenging address perfectly. The resolution can take hours if severe, and vehicles must voluntarily line up exit spots. Most state-of-the-art scheduling schemes often rely signal controllers mitigate in fixed areas intersection, blocked are...

Haptic guidance in a shared steering assistance system has drawn significant attention intelligent vehicle fields, owing to its mutual communication ability for control. By exerting continuous torque on the wheel, both driver and support can share lateral control of vehicle. However, current haptic systems demonstrate some deficiencies assisting lane changing. This study explored new interactio...

Abstract--This paper gives a complete analysis of the problem of aeroassisted return from a high Earth orbit to a low Earth orbit with plane change. A discussion of pure propulsive maneuver leads to the necessary change for improvement of the fuel consumption by inserting in the middle of the trajectory an atmospheric phase to obtain all or part of the required plane change. The variational pro...

We study the motion of kinks in a two-lane model of the totally asymmetric simple exclusion process with open boundaries. Once a lane change is allowed, the positions of the kinks become synchronized. We analytically study the motion of the kinks by a decoupled approximation. When we choose the lane change rate asymmetric, the difference between the positions of the kinks become zero, though th...
