For a decade, embedded driving assistance systems were mainly dedicated to the management of short time events (lane departure, collision avoidance, collision mitigation). Recently a great number of projects have been focused on cooperative embedded devices in order to extend environment perception. Handling an extended perception range is important in order to provide enough information for bo...

This work treats a problem relevant to automatic road following, collision avoidance, and maneuver control. A millimeter-wave radar is placed on the front of the vehicle and an image of the radar backscatter of the terrain is acquired in polar coordinates. This image contains both road and off-road scatter components which must be segmented from each other. Geometric constraints on the road edg...

In 2015, an estimated 38,300 people were killed and 4.4 million injured in motor vehicle crashes in the US alone, with damage costs exceeding $400 billion.1 In contrast, there were no commercial aviation fatalities and 136 civil aviation deaths in the US in 2015.2 More than 90 percent of auto accidents result from human impairment such as drunk driving or road rage, errant pedestrians, or just ...

The safe operation of a passenger/commercial ground vehicle requires continual judgment, mission planning, and driving skills by the operator. The departure of the tires from the prescribed road surface, labeled road runoff, represents a hazardous situation that must be properly handled to prevent unintended consequences. In this instance, the recommended actions are for the driver to recognize...

A sequential optimization method is applied to manage air traffic flow under uncertainty in airspace capacity and demand. To support its testing, a decision support system is developed by integrating a deterministic integer programming model for assigning delays to aircraft under en route capacity constraints to reactively account for system uncertainties. To reduce computational complexity, th...

One of the key applications envisioned for C-V2I (Cellular Vehicle-to-Infrastructure) networks pertains to safety on the road. Thanks to the exchange of Cooperative Awareness Messages (CAMs), vehicles and other road users (e.g., pedestrians) can advertise their position, heading and speed and sophisticated algorithms can detect potentially dangerous situations leading to a crash. In this paper,...

1853. May 1st. Departed from St. Rose's Kentucky, in company with Thomas Duffy for Europe. We drove to Louisville in a fine buggy, and made a grand appearance on the way, except that the seat was minus of cushions, thanks to the courtesy of our good Prior; but the defect was supplied with a grand quilt. We bid an affectionate farewell to the brothers, and the venerable spire of our convent was ...

Recently, autonomous vehicles, particularly self-driving cars, have received significant attention owing to rapid advancements in sensor and computation technologies. In addition to traffic sign recognition, road lane detection is one of the most important factors used in lane departure warning systems and autonomous vehicles for maintaining the safety of semi-autonomous and fully autonomous sy...
