Safety

The security of Advanced Traffic Management System (ATMS) proves to be vital as these systems are expanded to support regional traffic management, integrated with public safety, electronic toll collection and other systems, and become part of Homeland Security. Changes to critical ATMS subsystems by disgruntled employees, operators without permission and training to manage functions, hackers, or aggressive terrorists could create dangerous roadway situations. Password protection provides minimal security. Often times, passwords are not only lost or stolen, but also shared among employees. This paper provides insight on the security challenges faced by ATMS systems and proposes biometric fingerprint security as a viable solution. Biometric fingerprint scan technology has improved steadily over the last ten years. A discussion of finger print technology is provided along with information about the integration of this capability into existing ATMS systems.

A discrete-time model, which characterizes a driver’s braking behavior, is developed. According to the proposed model, the amount of braking depends on the current vehicle speed and the required stopping distance. The model is used to simulate the performance of the NHTSA (National Highway Traffic Safety Administration) Alert Algorithm. The simulation results indicate that, in the situation where an inattentive driver is approaching a stopped lead vehicle at 60 mph, the probability of collision is less than 17.6% when the NHTSA Alert Algorithm is in minimum sensitivity mode. In maximum sensitivity mode, the probability of collision is less than 3.2%.

The evaluation of a truck-based drowsy driver warning system through field operational test (FOT) data will provide an objective assessment of user- and device-provided performance data. The evaluation will address five areas: safety benefits, driver acceptance, fleet management acceptance, performance and capability, and deployment. This paper reviews the goals and objectives that the evaluation will pursue. Although the details of the plan will evolve as the FOT approaches, the information provided addresses the main topics and indicates the thoroughness with which the evaluation will be performed. Ultimately, the FOT and its subsequent evaluation will provide a useful contribution to public safety.

A new safety application, as part of ITS Advanced Rural Transportation System (ARTS), has been developed and deployed on a two-lane rural road (Route 114) in Southwest Virginia. The route has a rolling geometry of several vertical curves and is subject to significant head-on accidents. During the period 1994-2000, the road experienced 11 crashes that resulted in 12 fatalities and 29 injuries. All these accidents were a result of two main conditions:

1- Illegal passing maneuvers crossing solid yellow centerline, and

2- A short passing sight distance due to the road vertical profile.

Accidents reports indicated alcohol involvement in some of these incidents.

The main objective of the research, supported by Virginia Department of Transportation VDOT, is to design, install, test and evaluate a video detection-based warning system by installing an efficient system on one vertical crest curve on Route 114, capable of performing the following two main functions:

1. Detect vehicles that attempt to violate the no-passing zone.

2. Warn the violating drivers in order to discourage them from continuing their risky

maneuvers.

Presentation

•Objective

-Develop an interface that most effectively supports the human interaction with the Forward Collision Warning (FCW) and Adaptive Cruise Control (ACC) systems.

•Display Medium

-Full color, reconfigurable, 3 x 6 degree field of view Head-up display (HUD)

•Research

-Camp project effectively examined display issues for single stage FCW displays but did not address the possibility of multiple stage FCW displays afforded by the new HUD technology.

-The increased performance and driver-acceptance potential of multistage displays was demonstrated in a driving simulator at Delphi Delco.
