Safety

Collisions between vehicles at urban and rural intersections account for nearly a third of all reported crashes in the United States. This has led to considerable interest at the federal level in developing an intelligent, low-cost system that can detect and prevent potential collisions in realtime. We propose the development of a system that uses video cameras to continuously gather traffic data at intersections (e.g., vehicle speeds, positions, trajectories, accelerations/decelerations, vehicle sizes, signal status etc.) which might eventually be used for collision prediction. This paper describes some of the challenges that face such a system as well as some of the possible solutions that are currently under investigation.

This paper examines possible roles that TMCs can play in the event of homeland security threats, and raises other questions that should be considered in the design and operations of existing and future TMCs. Procedures, policies, and communication protocols that should be in place between the TMC and the EOC during potential terrorist attacks are discussed. Information that should be monitored, and how that information is verified, shared, and disseminated is also discussed. Finally, the paper recommends improvements to the existing protocols to maximize communication and coordination between the EOC and TMCs during homeland security events.

In this paper we introduce a system architecture general enough to encompass all intersection collision warning and gap advisory scenarios. We propose to use our architecture along with standardization of the subsystem interfaces in order to achieve efficiency, fast design and development, high subsystem reusability and high upgradeability.

The kernel of the proposed architecture is a “StateMap”, a data base of knowledge of all the dynamic components within and, to a reasonable range, approaching the intersection. A “state map generator” processes the inputs from a heterogeneous set of sensors into a standardized “state map”. The introduction of this subsystem makes faster and easier the development of safety application programs. At the same time it makes easier to reuse and upgrade applications.

The driver-adaptive system proposed in this paper is a trial of a driver assistance system for safety to increase the driver acceptance of the systems. The system, named the human centered ITS view aid system, is featured by driver monitoring and adaptive information display based on the monitoring results. The system consists of on-board sensing systems for road surface and inter-vehicle spacing, driver monitoring systems for eye closing and eye casting, inter-vehicle communications for transmission of data acquired by a preceding vehicle to a following vehicle, and an adaptive information display system. Some experimental results of the devices are introduced.

This paper describes GDOT’s proactive approach to hurricane evacuation using ITS technology. Specifically, GDOT hopes to decrease evacuation time and increase safety through the use of portable traffic management systems. These systems include surveillance cameras, dynamic message signs, and highway advisory radios on one portable platform. GDOT plans to place them on and near evacuation routes to increase evacuation visibility and real-time information to motorists, supplementing other key evacuation strategies, such as contraflow measures.
