Safety

FAST(Fast Emergency Vehicle Preemption System) is a system for supporting the travel of emergency vehicles, such as patrol cars, and its main functions are providing information, including  emergency vehicle route guidance and priority control of signals. The implementation of FAST is expected to reduce the number of accidents from emergency travel and to reduce the degree of severity of accidents by facilitating quick arrival at the scene, quick resolution of incidents, and speedy rescue activities.

A verification test was conducted in 1999, and FAST is scheduled for implementation in the Tokyo metropolitan area to support patrol cars in 2001. This paper discusses the verification results and the implementation of the system in the Tokyo metropolitan area.

Georgia’s Emergency Motorist Aid Call Box Pilot Project, the first call box system in the State, was installed in May 1999 to determine its effectiveness in providing emergency service to stranded motorists in Georgia. A total of 147 call boxes were installed on one of the most rural sections of Interstate in Georgia. The project is 39 miles in length and is located within Troup, Harris and Muscogee Counties on I-185.

The Georgia Department of Transportation (GDOT) was interested in determining the benefits and effectiveness of the system. Based on this evaluation, GDOT will determine whether it would be beneficial to install call boxes in other areas of the state.

The Minnesota Department of Transportation (Mn/DOT), the Minnesota State Patrol (MSP) and the Mayo Emergency Communications Center (MECC) teamed up with Veridian Engineering to develop an emergency communications infrastructure not only capable of directly accepting Mayday calls, but intelligent enough to accurately route calls to the proper authority depending on the geographic location of the incident.

Mayday Plus proved the operational success of the technologies developed during the project. The in-vehicle equipment proved the capability of sending three types of manual emergency requests and automatic notification in the case of simulated crash events. Dispatchers receiving Mayday Plus calls were able to quickly and efficiently locate incidents and forward data and calls as necessary to other agencies. However, in comparison to actual cellular 9-1-1 calls where the dispatcher must rely on the caller to obtain accurate location information, the complete location and crash data message sent by the Mayday Plus system proved to be slower. Minor changes to the design of the communication system are expected to improve this result. Nonetheless, while it cannot be a substitute for human intervention, it proved the success of providing accurate and relevant information that could further improve the quality of response to incidents. As well, in situations where the victim is unable to effectively communicate, it could possibly provide life-saving data.

This paper describes the results of a comprehensive evaluation of the Intelligent Cruise Control (ICC) system, based on an ICC Field Operational Test (FOT). The primary goal of the evaluation was to determine the safety effects of the ICC system. However, the evaluation also addressed three additional goals: characterize the ICC system and vehicle performance, determine user acceptance of the ICC system, and assess system deployment issues. With respect to evaluating ICC safety effects, it was concluded that use of the ICC system was associated with safer driving compared to manual control and, to a lesser extent, conventional cruise control, and is projected to result in net safety benefits if widely deployed. It was also found that, as a prototype, the ICC system performed remarkably well during the FOT. Furthermore, participants in the FOT had a high level of acceptance of the ICC system. Finally, it was found that use of the ICC system would promote reductions in fuel consumption and emissions.

Vehicle crash statistics in the U.S. are dominated by light vehicles at a rate in excess of 94% of all vehicles involved. This paper reviews the USDOT crash avoidance program for light vehicles being managed through the Intelligent Vehicle Initiative (IVI) within the Department’s Intelligent Transportation Systems Program.

The paper begins with crash statistics to define the crash problem for light vehicles in the U.S. Four major crash categories dominate the crash statistics, these being rear-end, lane change, road departure, and crossing path crashes (at junctions). Further, these categories are broken down into a total of 15 common pre-crash scenarios along with causal factors. The causal factors analyses identify driving task errors as the primary cause in about 75% of all crashes studied, thus indicating that driver assistance countermeasures could be very effective.

The paper next discusses the IVI programmatic approach to develop crash countermeasures for light vehicles, which requires a joint cooperative effort between Government and industry. The technical approach is described next, which is composed of baseline driver performance analyses, system performance specifications development, creation of human factors design guidelines, objective test development for countermeasure systems, and benefits analyses for the countermeasures.

The last section of the paper describes the current state of progress in each of the areas of the technical approach. Radar-based rear-end collision warning is currently the most mature of the countermeasures and is in final development for a field operational test to begin in 2002. Testbed vehicles are described for each of the four crash countermeasures. Progress in benefits methodology for the countermeasure evaluations is described.
