Book excerpt: The Emergency Vehicle Alert System (EVAS) program is sponsored by the NASA/MSFC Technology Utilization (TU) office. The program was conceived to support the needs of hearing impaired drivers. The objective of the program is to develop a low-cost, small device which can be located in a personal vehicle and warn the driver, via a visual means, of the approach of an emergency vehicle. Many different technologies might be developed for this purpose and each has its own advantages and drawbacks. The requirements for an acoustic detection system, appear to be pretty stringent and may not allow the development of a reliable, low-cost device in the near future. The problems include variations in the sirens between various types of emergency vehicles, distortions due to wind and surrounding objects, competing background noise, sophisticated signal processing requirements, and omni-directional coverage requirements. Another approach is to use a Radio Frequency (RF) signal between the Emergency Vehicle (EV) and the Personal Vehicle (PV). This approach requires a transmitter on each EV and a receiver in each PV, however it is virtually assured that a system can be developed which works. With this approach, the real technology issue is how to make a system work as inexpensively as possible. This report gives a brief summary of the EVAS program from its inception and concentrates on describing the activities that occurred during Phase 4. References 1-3 describe activities under Phases 1-3. In the fourth phase of the program, the major effort to be expended was in development of the microcontroller system for the PV, refinement of some system elements and packaging for demonstration purposes. An EVAS system was developed and demonstrated which used standard spread spectrum modems with minor modifications.

Book excerpt: The EVAS provides warning for hearing-impaired motor vehicle drivers that an emergency vehicle is in the local vicinity. Direction and distance to the emergency vehicle are presented visually to the driver. This is accomplished by a special RF transmission/reception system. During this phase the receiver and transmitter from Phase 1 were updated and modified and a directional antenna developed. The system was then field tested with good results. Static and dynamic (moving vehicle) tests were made with the direction determined correctly 98 percent of the time.

This book was released on 2012 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Today's transport system has evolved from horse driven carriages and paved roads to a more complex road transport system made up of a variety of vehicles and other infrastructure, all put in place in order to support safe and efficient mobility of vehicles. The next step to further improve the transportation system of today is to make the vehicles and roadside infrastructure more intelligent by making them communicate with each other. This new ability will help find new solutions to current problems like traffic congestion, vehicular collisions, monitoring of adherence to traffic rules and alerting the drivers of hazardous conditions. Vehicular Ad-Hoc Networks (VANETs) are vehicle to vehicle and vehicle to road side infrastructure networks which make this possible by providing support to numerous applications aimed towards improving safety and driving experience on the road. A Public Safety VANET application adhering to the IEEE Wireless Access in Vehicular Environments (WAVE) standard and requirements laid down by National Highway Traffic Safety Administration (NHTSA) was designed, implemented, simulated and tested over a scalable open-sourced test bed aimed towards simulating a complete Intelligent Transportation System consisting of various applications operating together. The application supports two features: Approaching Emergency Vehicle Alert: An Approaching Public Safety Vehicle (Police/Fire/EMS) in a state of emergency will alert the vehicles in its path using the VANET, causing them to give way. Post-Crash Warning: A vehicle involved in a crash will immediately alert approaching vehicles about its current state using the VANET, helping them come to a halt at a safe distance, hence avoiding pileups. The performance and adherence to the requirements was analyzed, and a demonstration of the system was prepared to showcase the application in action."--Abstract.

Book excerpt: The subject of visual and auditory warning devices (lights and sirens) for emergency and service vehicles is surveyed from a broad perspective. The report should provide directly useful information at all levels from the selection of hardware to a general understanding of the psychophysical factors determining the effectiveness of these devices. Topics covered include: an analysis of warning signals; the present situation and the need for uniform national standards; suggested performance standards for warning light systems and for sirens, including the reasons for the principal requirements; recommendations for actions that can be taken to improve the signal effectiveness of emergency vehicles; and brief summaries of some of the physical measurements that are made on a selection of lights and sirens.

Book excerpt: Following a series of natural disasters, including Hurricane Katrina, that revealed shortcomings in the nation's ability to effectively alert populations at risk, Congress passed the Warning, Alert, and Response Network (WARN) Act in 2006. Today, new technologies such as smart phones and social media platforms offer new ways to communicate with the public, and the information ecosystem is much broader, including additional official channels, such as government social media accounts, opt-in short message service (SMS)-based alerting systems, and reverse 911 systems; less official channels, such as main stream media outlets and weather applications on connected devices; and unofficial channels, such as first person reports via social media. Traditional media have also taken advantage of these new tools, including their own mobile applications to extend their reach of beyond broadcast radio, television, and cable. Furthermore, private companies have begun to take advantage of the large amounts of data about users they possess to detect events and provide alerts and warnings and other hazard-related information to their users. More than 60 years of research on the public response to alerts and warnings has yielded many insights about how people respond to information that they are at risk and the circumstances under which they are most likely to take appropriate protective action. Some, but not all, of these results have been used to inform the design and operation of alert and warning systems, and new insights continue to emerge. Emergency Alert and Warning Systems reviews the results of past research, considers new possibilities for realizing more effective alert and warning systems, explores how a more effective national alert and warning system might be created and some of the gaps in our present knowledge, and sets forth a research agenda to advance the nation's alert and warning capabilities.

Available in PDF, EPUB and Kindle. Book excerpt: The Emergency Alert System (EAS) is built on a structure conceived in the 1950¿s when over-the-air broadcasting was the best-available technol. for widely disseminating emergency alerts. It is one of several federally managed warning systems. The NOAA/NWS weather radio system has been upgraded to an all-hazard warning capability. The Dept. of Homeland Security is implementing a program that will disseminate nat. alert messages over digital broadcast airwaves, using satellite and public TV broadcast towers. This program is called the Integrated Public Alert and Warning System (IPAWS).
