This paper reports on AnnieWAY, an autonomous vehicle that is capable of driving through urban scenarios and that successfully entered the finals of the 2007 DARPA Urban Challenge competition. After describing the main challenges imposed and the major hardware components, we outline the underlying software structure and focus on selected algorithms. Environmental perception mainly relies on a r...

Research was conducted to assess driver acceptance and performance associated with a spotter mirror feature intended to reduce the incidence of lane-change conflicts by enhancing drivers' ability to detect vehicles in their side blind zone. The spotter mirror consisted of an integrated spherical convex blind zone mirror inset within a larger planar mirror. The spotter mirror's field-of-view was...

Distracted driving has received increasing attention in the literature due to potential adverse safety outcomes. An often posed solution to alleviate distraction while driving is hands-free technology. Interference by distraction can occur however at the sensory input (e.g., visual) level, but also at the cognitive level where hands-free technology induces working memory (WM) load. Active maint...

In a swing-by maneuver, the variation of energy spacecraft is controlled by angle, velocity, and distance approach. These parameters are defined incoming trajectory, when far from planetary atmosphere. The passage atmosphere generates aerodynamic forces, affecting its trajectory giving new forms control, which functions attitude spacecraft. This maneuver called aerogravity-assist maneuver. cont...

PURPOSE To investigate lamina cribrosa (LC) displacement during the Valsalva maneuver in young healthy eyes using enhanced depth imaging (EDI) spectral-domain optical coherence tomography (SD-OCT). METHODS Forty-eight eyes of 48 young healthy volunteers (age range: 20-34 years) underwent intraocular pressure (IOP) measurement by Goldmann applanation tonometry as well as Cirrus HD-OCT scans be...

Operating a robot safely and efficiently can be considerably challenging in an interactive and complex environment. Other surrounding agents may be cooperative or adversarial in their interactions with the robot. It will be desirable to develop control strategies that can enable the robot agent to handle diverse situations and respond with appropriate behaviors in an interactive environment. In...

This paper presents a novel lane detection scheme for detecting and tracking various lanes directly from videos in real time. The key contribution of this paper is to propose a new edge labeling scheme for labeling each edge point to different types. Even under different lighting and weather conditions, different lane segments still can be effectively extracted from the labeling result. Only th...

After describing the main challenges imposed and the major hardware components, we outline the underlying software structure and focus on selected algorithms. A recent laser scanner plays the prominen...

This work describes a micro simulation program that is developed to study freeway ramp merging phenomena under congested traffic conditions. First, the results of extensive macroscopic and microscopic studies are used to establish a model for the behaviour of merging drivers. A theoretical framework for modeling the ramp and freeway lag driver acceleration-deceleration behaviour is then present...
