Evaluation of MAYDAY/911 Field Operational Test FINAL Evaluation Report Evaluation of the MAYDAY/9-1-1 Field Operational Test Prepared for: Federal Highway Administration and National Highway Traffic Safety Administration By: In Association with: The Melcher Group July 19, 2006 Quality Assurance Statement The Federal Highway Administration provides high-quality information to serve Government, industry, and the public in a manner that promotes public understanding. Standards and policies are used to ensure and maximize the quality, objectivity, utility, and integrity of its information. FHWA periodically reviews quality issues and adjusts its programs and processes to ensure continuous quality improvement. July 19, 2006 i Final Evaluation Report Evaluation of MAYDAY /9-1-1 FOT Acknowledgement The national evaluation of the MAYDAY/9-1-1 project was performed under Battelle’s contract DTFH61-02-C-00134, Task BA34010 with the United States Department of Transportation (USDOT). This evaluation was conducted in association with Mr. Jim Goerke of the Melcher Group who serves as a sub-consultant to Battelle. The evaluation supports the on-going efforts of the Intelligent Transportation System (ITS) Joint Program Office (JPO) to assess the benefits of ITS deployments in the United States. Battelle wishes to acknowledge the guidance provided to the evaluation team by Ms. Laurie Flaherty of National Highway Traffic Safety Administration (NHTSA), who serves as the Government Task Manager (GOTM), and Mr. Ted Smith of Mitretek who provides support to Ms. Flaherty. Appreciation is also extended to Ms. Linda Dodge of the JPO who provided oversight to this evaluation; Dr. Joseph Peters who manages the national evaluation program within the JPO; the MAYDAY/9-1-1 Field Operational Test (FOT) team led by Mr. Bradley Estochen of the Minnesota Department of Transportation; and Mr. Jim Beutelspacher, 9-1-1 Program Manager of the Minnesota Department of Public Safety, who provided kind support to the conduct of various evaluation activities. Battelle also wishes to acknowledge the Mayo Clinic and many Public Safety Answering Point (PSAP) staff who provided invaluable support to this evaluation, especially Mr. Pete Eggimann with the Minneapolis/St. Paul Metropolitan Emergency Services Board who kindly provided coordination assistance.

Bayless Technology Scan Series 2011-2012 0 Connected Vehicle Insights: 4G Wireless: Vehicle and Highway Gateways to the Cloud ITS America INTRODUCTION With Fourth Generation cellular (4G), we will see the complete extension of the internet suite of protocols to the wireless environment. 4G likely represents the end of the traditional siloed telecommunications approach that has been the result of decades of investment in single-application “purpose built” wireless technologies (e.g. radio, TV, land mobile, and cellular) and regulatory practice. Current investment patterns in infrastructure provide a strong indication of what will be available and provided in what quantities, quality, and cost beyond 2015 for both terminal devices and network infrastructure. This paper examines how next generation wide-area cellular such as 4G will be able to support vehicular applications, and how transportation infrastructure may mesh with wireless networks. Specifically, it suggests that automotive electronics engineers will need to be cognizant of how application data is treated by 4G Long Term Evolution (LTE) networks, and how innovations such as self-organizing femto-cells, “traffic shaping” and heterogeneous or “vertical roaming” across different radio access technologies may improve the performance of off-board or “cloud” -based vehicular applications Furthermore, the paper suggests that over the long term, vehicles will serve as wireless gateways that manage and collect data a number of devices or sensors deployed in vehicles and highway infrastructure, utilizing 4G cellular as the last-mile wide-area connection to the cloud.

  • Working Together to Save Lives for Over 20 Years
    WORKING TOGETHER TO SAVE LIVES FOR OVER 20 YEARS INTRODUCING THE ONSTAR GUARDIAN APP A powerful new way to work together In a crash or emergency situation, getting the right help to the right place is essential. Emergency Communications Centers (ECCs) are challenged with determining the location of a 911 emergency call made from a smartphone. The new OnStar Guardian™ app is designed to help. In addition to key OnStar® safety services for crashes, emergencies and vehicle problems, the app uses GPS information that can provide you with a caller’s location — more precise location information than a cellphone tower ping. OnStar Guardian gives Members a little peace of mind in the palm of their hands — and it provides public safety professionals with a powerful location tool. HOW ONSTAR GUARDIAN WORKS The OnStar Guardian app is designed to give Members key OnStar safety services in or out of any vehicle. Wherever they take their smartphone, they have OnStar. MOBILE CRASH RESPONSE The OnStar Guardian app is designed to work with a smartphone’s built-in sensors. It can recognize the distinct shock caused by most vehicle crashes. To prevent false positives, the app uses a unique algorithm that ensures it is measuring a vehicle in motion — a consistent speed threshold for a consistent amount of time. When that pattern is disrupted by a shock, a crash is detected. The way Mobile Crash Response functions depends on the mobile operating system on which it is running. Android™ phones: When a crash is detected, OnStar Guardian automatically connects to OnStar. An Emergency-Certified Advisor can take the call and start communicating with the Member over the phone’s speaker or connected Bluetooth® device Apple® phones: When a crash is detected, OnStar Guardian automatically connects to OnStar.

  • Interworking of DSRC and Cellular Network Technologies for V2X Communications: a Survey
    Interworking of DSRC and Cellular Network Technologies for V2X Communications: A Survey Khadige Abboud, Hassan Aboubakr Omar, and Weihua Zhuang, Fellow, IEEE Abstract—Vehicle-to-anything (V2X) communications refer to caused highway users in the U.S. to spend extra unnecessary information exchange between a vehicle and various elements of 6.9 billion hours on roads to consume additional 3.1 billion the intelligent transportation system, including other vehicles, gallons of fuel, adding up to an annual economical loss of pedestrians, Internet gateways, and transport infrastructure (such as traffic lights and signs). The technology has a great $160 billion [2]. The statistical highway data from 1982 to potential of enabling a variety of novel applications for road 2014 show that these problems will continue to increase safety, passenger infotainment, car manufacturer services, and unless drastic new policy and technological measures are vehicle traffic optimization. Today, V2X communications is based taken [2]. To address these problems, there have been world- on one of two main technologies: dedicated short range com- wide efforts from auto companies, academic institutions, and munications (DSRC) and cellular networks. However, in the near future, it is not expected that a single technology can government agencies to provide the vehicles and the transport support such a variety of expected V2X applications for a large infrastructure with communication capabilities, thus enabling number of vehicles. Hence, interworking between DSRC and vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and cellular network technologies for efficient V2X communications vehicle-to-pedestrian communications, which are collectively is proposed. This paper surveys potential DSRC and cellular referred to as vehicle-to-x (V2X) communications, as recently interworking solutions for efficient V2X communications.
