Automated surveillance of 911 call data for detection of possible water contamination incidents
<p>Abstract</p> <p>Background</p> <p>Drinking water contamination, with the capability to affect large populations, poses a significant risk to public health. In recent water contamination events, the impact of contamination on public health appeared in data streams monitoring health-seeking behavior. While public health surveillance has traditionally focused on the detection of pathogens, developing methods for detection of illness from fast-acting chemicals has not been an emphasis.</p> <p>Methods</p> <p>An automated surveillance system was implemented for Cincinnati's drinking water contamination warning system to monitor health-related 911 calls in the city of Cincinnati. Incident codes indicative of possible water contamination were filtered from all 911 calls for analysis. The 911 surveillance system uses a space-time scan statistic to detect potential water contamination incidents. The frequency and characteristics of the 911 alarms over a 2.5 year period were studied.</p> <p>Results</p> <p>During the evaluation, 85 alarms occurred, although most occurred prior to the implementation of an additional alerting constraint in May 2009. Data were available for analysis approximately 48 minutes after calls indicating alarms may be generated 1-2 hours after a rapid increase in call volume. Most alerts occurred in areas of high population density. The average alarm area was 9.22 square kilometers. The average number of cases in an alarm was nine calls.</p> <p>Conclusions</p> <p>The 911 surveillance system provides timely notification of possible public health events, but did have limitations. While the alarms contained incident codes and location of the caller, additional information such as medical status was not available to assist validating the cause of the alarm. Furthermore, users indicated that a better understanding of 911 system functionality is necessary to understand how it would behave in an actual water contamination event.</p

Regional Data Archiving and Management for Northeast Illinois
This project studies the feasibility and implementation options for establishing a regional data archiving system to help monitor
and manage traffic operations and planning for the northeastern Illinois region. It aims to provide a clear guidance to the
regional transportation agencies, from both technical and business perspectives, about building such a comprehensive
transportation information system. Several implementation alternatives are identified and analyzed. This research is carried
out in three phases.
In the first phase, existing documents related to ITS deployments in the broader Chicago area are summarized, and a
thorough review is conducted of similar systems across the country. Various stakeholders are interviewed to collect
information on all data elements that they store, including the format, system, and granularity. Their perception of a data
archive system, such as potential benefits and costs, is also surveyed. In the second phase, a conceptual design of the
database is developed. This conceptual design includes system architecture, functional modules, user interfaces, and
examples of usage. In the last phase, the possible business models for the archive system to sustain itself are reviewed. We
estimate initial capital and recurring operational/maintenance costs for the system based on realistic information on the
hardware, software, labor, and resource requirements. We also identify possible revenue opportunities.
A few implementation options for the archive system are summarized in this report; namely:
1. System hosted by a partnering agency
2. System contracted to a university
3. System contracted to a national laboratory
4. System outsourced to a service provider
The costs, advantages and disadvantages for each of these recommended options are also provided.ICT-R27-22published or submitted for publicationis peer reviewe

Are low cost accountability, communications, and management systems for emergency first responders using 3G and 4G cellular technologies feasible?
Reliable, easily deployed communication networks are a necessity for emergency responders as the coordination of their efforts and their safety depend on it. As a volunteer firefighter, this researcher is aware of the shortcomings of the current communication technologies presently deployed, and the risks it poses to firefighters. Some studies have proposed deployment of sophisticated hybrid, mesh networks and mobile ad hoc networks that allow for location tracking, environment and personnel vital signs monitoring, and data communications. Unfortunately the cost of these systems and required training in use of the equipment inhibits their adoption and wide scale deployment across the nation\u27s emergency responder agencies. We are surrounded by secure, reliable cellular network technologies that meet our voice and data communication needs, yet current studies focus on building network infrastructures from the ground up and discussing how to address the security and performance issues of their proposed networks. This study proposes the use of the existing cellular network architecture already in place across the nation as a foundation to explore the feasibility of a low cost communication, management and accountability system utilizing 3G and 4G technologies and architecture
An Inquiry Regarding the Development of an Effectual Architecture Framework Supporting Next Generation 9-1-1
The emergency 9-1-1 service is a vital part of our nation â„¢s emergency response and disaster preparedness systems. At last count there were 6100 Public Safety Answering Points across the United States, 97 of those reside in the State of Colorado, and the citizens of the United States cannot email, text, or instant message these types of non-traditional communication to those Public Safety Answering Points due to technological limitations. The trends in personal communication technologies are accelerating the obsolescence of the current 9-1-1 systems. The Public Safety Answering Point of today is designed to accept and process voice media only; and proved successful in delivering emergency services in times of personal, regional, and national need. The current circuit-switched infrastructure of the 9-1-1 Public Safety Answering Point network cannot receive digital data (e.g., text messages, email, photographs, and video) from the communication devices commonly used by the public today. A national movement known as Next Generation 9-1-1 is underway that will support non-traditional communication digital data processing in the Public Safety Answering Point. This case study will attempt to determine if practical service oriented architecture methodology can be used in the development of an effectual architecture framework supporting the Next Generation 9-1-1framework and the nontraditional communication technology within the Public Safety Answering Points of Colorado
