In August of 1997, The US National Automated Highway System Consortium (NAHSC) presented a proof of technical feasibility demonstration of automated driving. The 97 Demo took place on car-pool lanes on I15 in San Diego, California. Members of the Consortium demonstrated many different functions, including: Vision-based road following Lane departure warning Magnetic nail following Radar reflecti...

Traffic information systems have become a major issue in many countries as a modern technology for alleviating traffic congestion in urban areas. Pre-trip or en-route real-time travel information regarding traffic conditions can enhance drivers’ knowledge of the situation in road networks and may assist in drivers’ decisions such as the choice of departure time, route, and destination. In facts...

This paper develops a novel positive model for departure time choice under road pricing and uncertainty at the individual levels, and analyzes the consequent system-level dynamic properties. The proposed modeling framework avoids assumptions of substantial rationality, and focuses on how individuals actually make decisions. Bayesian learning, knowledge updating, search, and decisionmaking under...

In road-transportation terminology, ADAS (Advanced Driver Assistance System) is a combination of monitoring-, alarm-, and control systems for increasing safety level in vehicles. Most of ADAS systems are infrastructureindependent and autonomous. This means these systems must work without any external awareness systems on the roads during the drive. Nevertheless, there are some systems which can...

Transportation infrastructure impedes the movement of animals, enhances their mortality due to collisions with vehicles, and decreases habitat size. We study the first two effects, using a spatially explicit individual-based model of population dynamics. We discuss the suitability of fences. Fences can either enhance or reduce survival probability, depending on the degree of road avoidance and ...

Each year, many preventable highway automobile accidents involving single vehicles are caused by inattention and distraction. These accidents are classified as single vehicle road departures. Lane departure and curve negotiation warning systems are an emerging technology to help prevent these types of accidents. I plan to build a road departure warning system that learns individual driver behav...

On U.S. highways single-vehicle road-departure (SVRD) accidents account for approximately one fourth of all accidents and one third of all fatalities. This paper describes an active safety system to help prevent SVRD accidents. Many aspects of the proposed system have been implemented on a prototype vehicle, and evaluated in driving tests. In addition to providing an overview of this vision-bas...

There is a critical need for improved departure management during convective weather events in the highly congested airspace in the Northeast and upper Midwest. An early study (Allan, 2001) of the New York Integrated Terminal Weather System (ITWS) prototype suggested that small increases in New York airport departure rates during Severe Weather Avoidance Programs (SWAP) could result in signific...

Vehicle rollover represents a significant percentage of single-vehicle accidents and accounts for over 9000 fatalities and over 200,000 non-fatal injuries each year. Previous research has yielded rollover stability control systems that are effective in on-road conditions.Accident statistics show, however, that over 90% of rollovers involve road departure, during which a vehicle may encounter sl...
