Abstract:
We propose a novel emergency alert broadcast mechanism for mobile phone users, which is based on the convergence of 5G and ATSC 3.0. Cellular networks including 5G adopt a broadcast technique for emergency alert. This technique just delivers a text-based message. Moreover, the message only includes a limited number of characters. Therefore, cellular networks cannot afford to provide abundant information in emergency cases. Broadcast networks such as ATSC 3.0 also offer an emergency alert broadcast service. This service can deliver a multimedia-based message in emergency cases. Therefore, the ATSC 3.0 supports more abundant information in the cases of emergency alert broadcasts. Especially, the ATSC 3.0 employs wake-up functionality and location information, which enables the delivery of emergency alerts to idle-state receivers in emergency areas. However, it is unlikely that the wake-up functionality and the location information are directly applicable to mobile phone users due to some practical issues. In order to improve the emergency alert broadcast service in mobile environments, we converge the 5G and the ATSC 3.0 networks, which effectively exploits the advantages of the networks. For the convergence network, we suggest a modified table, which associates the 5G message with the ATSC 3.0 message in the cases of emergency alerts. We also present a novel scenario for delivery of the emergency alert messages. Simulation results show that the convergence significantly enhances the receiver performance for emergency alert broadcast.

Abstract:
Abstract Worker safety is of the utmost importance; consequently, construction project sites use alert systems to notify project team members of emergencies on the job site. Various emergency alert systems are available in the construction industry, from the simple air horn to the more complex remote and app-based systems. This research aims to improve construction safety by investigating emergency alert systems that notify workers of widespread emergencies on the project site. The objectives are to identify the types of emergency alert systems available in the construction industry, explore the industry professionals’ perceptions of the existing emergency alert systems, and identify any gaps in the market for new technologies or the potential for improving existing ones. This study utilizes a survey of 34 industry professionals to identify the most commonly used emergency alert systems on jobsites and their knowledge and perceptions of app-based and remote emergency alert systems. Results indicate that while the air horn is the most used method of emergency alerts, the construction industry may be willing to spend more on remote emergency alert systems than app-based emergency alert systems. The primary concerns of the construction industry are the overall cost, the reliability of the high-tech systems, and the potential for false alarms. It appears that if the construction professionals’ concerns are addressed, they would be willing to spend more on app-based systems.

Abstract:
Background Physicians’ alert overriding behavior is considered to be the most important factor leading to failure of computerized provider order entry (CPOE) combined with a clinical decision support system (CDSS) in achieving its potential adverse drug events prevention effect. Previous studies on this subject have focused on specific diseases or alert types for well-defined targets and particular settings. The emergency department is an optimal environment to examine physicians’ alert overriding behaviors from a broad perspective because patients have a wider range of severity, and many receive interdisciplinary care in this environment. However, less than one-tenth of related studies have targeted this physician behavior in an emergency department setting. Objective The aim of this study was to describe alert override patterns with a commercial medication CDSS in an academic emergency department. Methods This study was conducted at a tertiary urban academic hospital in the emergency department with an annual census of 80,000 visits. We analyzed data on the patients who visited the emergency department for 18 months and the medical staff who treated them, including the prescription and CPOE alert log. We also performed descriptive analysis and logistic regression for assessing the risk factors for alert overrides. Results During the study period, 611 physicians cared for 71,546 patients with 101,186 visits. The emergency department physicians encountered 13.75 alerts during every 100 orders entered. Of the total 102,887 alerts, almost two-thirds (65,616, 63.77%) were overridden. Univariate and multivariate logistic regression analyses identified 21 statistically significant risk factors for emergency department physicians’ alert override behavior. Conclusions In this retrospective study, we described the alert override patterns with a medication CDSS in an academic emergency department. We found relatively low overrides and assessed their contributing factors, including physicians’ designation and specialty, patients’ severity and chief complaints, and alert and medication type.

Abstract:
Modern cell phones are required to receive and display alerts via the Wireless Emergency Alert (WEA) program, under the mandate of the Warning, Alert, and Response Act of 2006. These alerts include AMBER alerts, severe weather alerts, and (unblockable) Presidential Alerts, intended to inform the public of imminent threats. Recently, a test Presidential Alert was sent to all capable phones in the U.S., prompting concerns about how the underlying WEA protocol could be misused or attacked. In this paper, we investigate the details of this system and develop and demonstrate the first practical spoofing attack on Presidential Alerts, using commercially available hardware and modified open source software. Our attack can be performed using a commercially available software-defined radio, and our modifications to the open source software libraries. We find that with only four malicious portable base stations of a single Watt of transmit power each, almost all of a 50,000-seat stadium can be attacked with a 90% success rate. The real impact of such an attack would, of course, depend on the density of cellphones in range; fake alerts in crowded cities or stadiums could potentially result in cascades of panic. Fixing this problem will require a large collaborative effort between carriers, government stakeholders, and cellphone manufacturers. To seed this effort, we also propose three mitigation solutions to address this threat.

Abstract:
ObjectivesPrehospital notifications (pre-alerts) enable emergency department (ED) staff to prepare for the arrival of patients requiring a time-critical response. Effective communication of the pre-alert is key to enabling the ED to prepare appropriately, but evidence on communication practices is lacking. We undertook qualitative research to understand how pre-alert communication may be improved to optimise the ED response for pre-alerted patients.Design, setting and participantsData collection took place within three UK Ambulance Services and six EDs between August 2022 and April 2023. We undertook semi-structured interviews with 34 ambulance and 40 ED staff and 156 hours non-participation observation of pre-alert practice (143 pre-alerts). Verbatim interview transcripts and observation notes were imported into NVivo and analysed using a thematic approach.ResultsWe identified significant variation in how pre-alerts were communicated that influenced how effectively information was transferred. Ambulance and ED staff demonstrated a shared recognition that pre-alerts need to be communicated concisely, but both received minimal training in how to give and receive pre-alerts. Efficient pre-alerting was influenced by clinician experience and seniority. ED and ambulance clinicians following different information-sharing formats sometimes led to interruptions, information loss and tensions, particularly when an early ‘headline’ clinical concern had not been shared. Ambulance clinicians sometimes questioned the appropriateness of their pre-alert when ED clinicians did not explain the rationale for not giving the expected response (that is, being accepted into a high-priority area of the ED). Additional sources of frustration included technological problems and poor communication of estimated time of arrival and caller/responder identities.ConclusionsUse of a shared format, including a headline ‘cause for concern’, may improve the clarity, usefulness and civility of pre-alerts, particularly when the clinician’s concern is not obvious from observations. Basic training on how to undertake pre-alerts for both ED and ambulance clinicians may improve understanding of the importance of pre-alert communication.Trial registration numberISRCTN12652860.

Abstract:
This study is based on the creation of a Python-based plugin as an SMS alert module for emergency response planning in QGIS. The project involves performing GIS analysis on vector layers and generating SMS alerts. For example, when disasters and emergencies such as natural disasters, accidents, medical crises, or security threats occur, there is a need for rapid dissemination of information. It can happen to anyone, anywhere, at any time. The purpose of the risk assessment phase of an emergency response plan is to explore potential emergency scenarios. Such a facility develops and implements an emergency plan for the safety of its personnel, guests, customers, and other visitors. When emergencies occur, the SMS Alerts plugin will provide an immediate and direct way to reach individuals in real-time. Emergency alerts can be received on almost all mobile phones in the nearby emergency area. For example, if a disaster occurs, we need to send an alert message to all hospitals in the area to alert them of the situation so that necessary action can be taken immediately. We need to send a warning message to a specific area. The user will get a warning message and all the information about all the events in the specific area where the buffer is created. The user gets all the information about the event, whether it is a positive or negative one. Keywords:- QGIS, SMS Alert, Plugin, GIS Analysis and Vector Data.

Abstract:
Android smartphone app will automatically detect the accident that will be occurred. The app immediately retrieves the GPS location and activates an alarm screen. With one tap, the user can request emergency assistance. The app calls the local emergency number and sends SMS alerts to predefined contacts. The alerts provide accident details including location coordinates, number of passengers, and crash characteristics. Development challenges include accurately identifying crashes across varying conditions while minimizing false positives, integrating with onboard vehicle systems for additional data, addressing cybersecurity risks, optimizing for minimal battery usage, and easing privacy concerns over data collection. If technical obstacles can be overcome, such an automated crash detection and emergency alert app could help expedite emergency responses and improve road safety outcomes. Intended as an low-cost, scalable supplementary crash alert system, it has the potential to save lives worldwide.

Abstract:
Introduction: Prehospital sepsis alerts assist paramedics in identifying patients with sepsis and in communicating this diagnosis to receiving facilities. Following the prospective implementation study of our regional systemic inflammatory response syndrome-based alert criteria (Alert), the purpose of this sub-study was to determine the cause of Alert false negatives (patients without an Alert that subsequently met sepsis criteria in the Emergency Department (ED)). Additionally, the sensitivity of the Alert for detecting sepsis was compared to the Quick Sequential Organ Failure Assessment (qSOFA) and Hamilton Early Warning Score (HEWS). Methods: This study was an additional analysis of the prospective Alert implementation study. Included patients were ≥ 18 years old, transported by a regional Emergency Medical Service and met severe sepsis or septic shock criteria (SS/SS, 2012 Surviving Sepsis Guidelines) in regional EDs in 2013. False negative patients were identified prospectively and reviewed by comparing paramedic determined Alert status to the retrospective application of the Alert criteria to Paramedic Call Report (PCR) data. The Alert sensitivity was first calculated from prospective data, then retrospective sensitivities of the Alert, qSOFA and HEWS were calculated by retrospectively applying these tools to PCRs, using ED diagnosis of SS/SS as reference standard. Results: In 2013, 229 patients met SS/SS criteria in the ED and had PCRs available; 115 (50.2%) were male and median age [interquartile range] was 76.0 [63.0-84.0]. Of 229, 149 (65.0%) arrived in the ED without an Alert (false negatives) and 46 (30.9%) of these met Alert criteria retrospectively and were therefore missed by paramedics. Sensitivity of the Alert was 34.9% when applied by paramedics and 41.5% when applied retrospectively to PCRs. The retrospective sensitivities of the qSOFA and HEWS were 37.6% and 67.7%, respectively. Conclusion: In ED patients diagnosed with SS/SS who arrived with no Alert, the majority (69.1%) were missed by the Alert criteria, rather than by paramedic application of the tool. The Alert had a sensitivity of 34.9%. When applied retrospectively and compared to the Alert, qSOFA had similar sensitivity and HEWS had increased sensitivity. Future research should focus on deriving improved alerts or implementing those with higher accuracy, such as HEWS.

Abstract:
BackgroundAmbulance clinicians use pre-alert calls to inform receiving emergency departments (EDs) of the arrival of a critically unwell patient that will require a specialised response. Little is known about how a decision to pre-alert is made and how this is communicated and acted upon in the receiving ED. Whilst appropriate use of pre-alerts benefits patient care, their overuse carries a risk of harm or opportunity costs. The impact of pre-alerts on ambulance clinicians, ED staff and patients is not currently well understood.MethodsWe are conducting a mixed methods study with five inter-related work packages. We will analyse 12 months of routine data from ambulance pre-alerts in three regions to identify factors in the variation of pre-alert use, including pre-hospital decision-making. We will undertake a national online Qualtrics survey of ambulance clinician perspectives and experience of pre-alerts. We will explore the impacts of a pre-alert on staff, ED facilities and the patient using semi-structured interviews with ambulance clinicians, ED staff, patients and carers and undertake non-participant observation of ED pre-alert response.Expected ResultsWe will describe current pre-alert practice using 12 months’ data for 3 Ambulance Services, including volume and types of pre-alerts. We will identify specific conditions or patient groups for whom pre-alerts are most likely to lead to change in clinical practice, or for whom action is unlikely to provide benefit. We will hold a feedback workshop in which we will share and discuss our findings with key stakeholders.ConclusionsCurrent variation in pre-alert processes, both pre-hospital and in-hospital and the impact on patient care is not understood. The outputs of this study will establish an evidence base to update national guidance for pre-alert practice and identify areas of good pre-alert practice for both ambulance service and Emergency Department staff.

Abstract:
A novel interface to provide robust, intuitive, and timely alerts to road users to move over for emergency vehicles (EVs) was tested in a seven-minute driving-simulator experiment. The interface, Augmented Emergency Lighting (AEL), mimics emergency lighting on emergency vehicles (i.e., flashing blue light), by using the cars’ interior lighting. AEL was initiated 30 seconds before an EV caught up and increased its brightness proportionally to the distance to the EV. The AEL alert was after 16 seconds accompanied by an Emergency Vehicle Approaching (EVA) alert, presented as a voice command and a text message on the dashboard. Comparisons were made between AEL+EVA alerts, EVA-only alerts, and no alerts, between groups (N = 61). Both AEL+EVA alerts and AEL-only alerts were highly successful in getting drivers to move over by slowing down and pulling off to the side as compared to when there were no alerts, but no significant difference between AEL+EVA and EVA-only was found. Questionnaire responses showed that AEL+EVA alerts were generally appreciated and that their timing was good. Further studies on learning effects and usability are discussed.

Abstract:
<p>Cell Broadcast (CB) is a possible technical realisation of a global emergency alert system. It is a technique used for sending short text messages to all mobile stations (MSs) in a defined geographical area. An potential effect of using CB is the increase in battery consumption of the MS due to the fact that an extra channel has to be used to make the service available even when the network is otherwise congested. Another part of the service which leads to a potential problem is making CB messages available in different languages. Investigating these problems is the objective of this thesis and the studies it includes. During the first part of the thesis, we measured the battery consumption of MSs in different modes of operation in order to analyse how CB affects the amount of current drained. The tests showed that battery consumption increased only slightly when CB messages were being received at the MS. Although some of the results can be, and are, discussed, we believe that CB would have a small effect on the power consumption of an MS, particularly in a context where it would be used for emergency warning messages only. This mentioned, it would however be wishful to confirm the conclusions further through the realisation of long-term testing. The second part of the thesis deals with the investigation of the MSs’ support for CB messages with different coding schemes. Based on the investigation’s result, we have come to the conclusion that in the long term the usage of different coding schemes on the same channel is preferred. However, the usage of one, global, emergency channel is hard to realise since that requires a standardisation between all countries. In our opinion this may be achieved first in the long run and until then, the usage of separate channels seems to be necessary.</p>

Abstract:
Crises are spontaneous and highly variable events that lead to life threatening and urgent situations. As such, crisis and emergency notification systems need to be both flexible and highly optimized to quickly communicate to users. Implementing the fastest methods, however, is only half of the battle. The use of geospatial location is missing from alert systems utilized at university campuses across the United States. Our research included the design and implementation of a mobile application addition to our campus notification system. This addition is complete with optimizations including an increase in the speed of delivery, message differentiation to enhance message relevance to the user, and usability studies to enhance user trust and understanding. Another advantage is that our application performs all location data computations on the user device with no external storage to protect user location privacy. However, ensuring the adoption of a mobile application that requests location data permissions and relating privacy measures to users is not a trivial matter. We conducted a campus-wide survey and interviews to understand mobile device usage patterns and obtain opinions of a representative portion of the campus population. These findings guided the development of this mobile application and can provide valuable insights which may be helpful for future application releases. Our addition of a mobile application with geospatial location awareness will send users relevant alerts at speeds faster than those of the current campus notification system while still guarding user location privacy, increasing message relevance, and enhancing the probability of adoption and use.<br>Master of Science

Abstract:
Titel: Sjuksköterskors upplevelse av att arbeta med hastigt försämrade patienter efter genomförd ALERT-utbildning Bakgrund: Patienter som fått hjärt- och/eller andningsstillestånd på vårdavdelningar och som läggs in på intensivvårdsavdelning (IVA) har haft försämrade vitalparametrar redan 6-8 timmar innan ankomst till IVA. 50 % av dessa inläggningar hade kunnat förhindras om personalen på avdelningen haft rätt kunskap i att upptäcka varningssignaler och hur de åtgärdas. ALERT-utbildningen uppmuntrar till användandet av ett enkelt verktyg för bedömningen av patienter, vilket leder till ökat självförtroende och minskad ångest i hanteringen av akut sjuka patienter och intensivvård kan undvikas eller sättas in i rätt tid. Syfte: Att undersöka sjuksköterskors upplevelse av att arbeta med hastigt försämrade patienter efter genomförd ALERT-utbildning Metod: Intervjuer med tolv allmänsjuksköterskor på kirurgisk och medicinsk vårdavdelning. Insamlad data analyserades med kvalitativ innehållsanalys. Resultat: Vid analys av texten framkom totalt tre övergripande teman; Ökad förmåga till tidigare varseblivning, Känsla av ökad trygghet i sjuksköterskerollen och Upplevelse av ökad patientsäkerhet. Dessa teman mynnade ut i sex subteman; Tidiga varningssignaler uppmärksammas, Kontroller samt åtgärd vid hastig försämring, Ökat självförtroende, Viktigt med repetition, Struktur ger säkerhet i arbetet samt Sjuksköterskornas stöd för att bedöma olika vitalparametrar. Slutsats: Sjuksköterskorna upplever att ALERT-utbildningen ökar deras självförtroende och höjer patientsäkerheten, samt att regelbundna repetitioner är viktigt för att upprätthålla kunskapen.

Abstract:
Following the attacks of September 11th, the growing fear of a bioterrorist attack emerged within the United States and pushed the threat of bioterrorism to the forefront of the public health emergency preparedness and response agenda. Despite the investment of more than six billion dollars in federal funding towards emergency preparedness and response initiatives, well defined and broadly accepted performance measures for determining the efficacy of these systems have yet to be established. Because of the complex and dynamic conditions under which emergency preparedness and response systems must perform, it is becoming apparent that traditional measures of evaluating the performance of public health systems simply will not suffice. The inability to accurately capture and quantify this information has created knowledge gaps which hinder our ability to measure our true level of preparedness and ultimately weakens our response capacity. It is therefore essential that we develop methodologies that enable us to establish valid metrics which capture the information needed to quantify the capacity and efficacy of these systems. As a key information sharing and communication component of North Carolinaâs Public Health Information Network (NC PHIN), the North Carolina Health Alert Network (NCHAN) serves as a promising means to measure emergency preparedness and response capacity. The goal of this thesis is to present a methodology for extending approaches in operations research and systems engineering to better understand the value of emergency preparedness and response systems, such as NCHAN. Ultimately we seek to determine how NCHAN has aided to emergency preparedness and response by quantifying the added value of the system to the greater âpreparedness and responseâ process. We demonstrate the use of statistical analysis, simulation and the IDEF0 mapping process as valid tools for modeling and quantifying the less-tangible aspects of emergency preparedness and response. We find that although the capacity exists within NCHAN to increase emergency preparedness and response, other factors, such as usage variability amongst NCHAN users, lack of integration with other NC PHIN components, and limited capacity of tangible system resources (such as labs, funding and public health practitioners) limits the efficacy of NCHAN. These findings suggest that user standardization, component integration and proper resource allocation will be necessary in order to realize the true value of emergency preparedness and response systems.

Las áreas de atención en el Servicio de Emergencia fueron; Reposo (41,6%), Hospitalización (33,9%) y Trauma shock (24,5%). Mediante curvas ROC, se determinó los puntos de corte para predicción de mortalidad y complicaciones, mostrándose para el caso de la escala APACHE II una notable discriminación a partir del valor 14 obtenido en la evaluación al ingreso. Para el caso de la escala MEWS, el punto de corte que mejor discrimina fue el valor 4 al ingreso, sin embargo se encontró que el punto de corte para el MEWS a las 12, 24, 36 y 48 horas fue el valor 3. En la evaluación de la capacidad predictiva de las Escalas APACHE II y MEWS de mortalidad se encontró que la escala MEWS medido a las 12 horas presentó mayor sensibilidad (76%) comparada con la escala APACHE II (71%) y una especificidad alta (61%) pero no superior a la Escala APACHE II (71%). El valor predictivo positivo y negativo de la escala APACHE II presentó valores superiores al resultado de la escala MEWS, siendo estos valores en la escala APACHE II, VP+ (33%) y VP- (93%) y la escala MEWS VP+ (29%) y VP- (92%). En cuanto a la capacidad de las escalas en predecir complicaciones se encontró que la escala MEWS medido a las 12 horas presentó mayor sensibilidad (68%) comparada con la escala APACHE II (61%) y una especificidad alta (62%) pero no superior a la escala APACHE II (71%); en cuanto al VP+ y VP- la escala APACHE II presentó valores superiores o similares a la escala MEWS. La evolución de los pacientes luego de su permanencia y seguimiento durante 7 días fue buena (40,8%), estacionaria (40,2%) y desfavorable (19,0%), además se encontró una relación significativa entre la escala NEWS evaluada a las 12 horas con la evolución del paciente a los 7 días (p<0.001). De los 505 pacientes atendidos, 84 (16,6%) de ellos fallecieron durante los 7 días de seguimiento. Se concluye que la escala MEWS medido a las 12 horas de ingreso al Servicio de Emergencia presenta una buena capacidad predictiva de complicación y mortalidad en pacientes con patología aguda atendidos en el Hospital Nacional Alcides Carrión.<br>Trabajo académico

Deste modo, com base, na análise de fontes orais, na documentação dos arquivos dos referidos Grupos de Escoteiros, nos registros da União dos Escoteiros do Brasil, fotografias e jornais, buscamos refletir como um movimento educativo pensado para a realidade dos jovens ingleses do início do século XX, conseguiu atrair tantas crianças para as suas fileiras na cidade de Campina Grande, na década de 1980-1990, quase cem anos depois de sua criação? Partindo da premissa de que os Grupos de Escoteiros são espaços disciplinares, cujo objetivo é a formação do jovem educado, cumpridor dos seus deveres e útil para a sociedade, refletimos sobre a aplicação do Método Escoteiro, entendido em nosso trabalho como um mecanismo que cumpre a função de disciplinar o corpo, a mente e as emoções dos escoteiros. Analisamos ainda as práticas simbólicas que perpassam o escotismo, responsáveis por estabelecerem a coesão e o sentimento de pertença entre os membros escoteiros, buscando a construção de uma identidade comum. Para a concretização desta pesquisa dialogou-se como alguns autores, a exemplo de FOUCAULT (1987) e suas reflexões teóricas sobre o poder disciplinar, BOSI (1994) e HALBWACHS (1990) acerca da memória, HALL (2005) que nos deu subsídio para discutir a produção de identidades, CHARTIER (1990) e sua análise sobre as representações sociais, CERTEAU (1994) sobre as táticas de resistência, dentre outros.<br>The following study has as objective to problematize the scouts practices lived, in the city of Campina Grande - PB, in the decades of 1980-1990, reflecting about the discipline of the bodies and the building of identities in the scout groups (General Sampaio, Santos Dumont and Batiruté). Thus, based on the analysis of oral sources, in the files documentation of the referred scout groups, in the records of the Union of Scouts Brazil, photographs and newspapers, we reflect as an educational movement thought to the reality of young Englishmen of the early twentieth century, has attracted many children to their ranks in the city of Campina Grande, in the decade of 1980-1990, nearly a hundred years after its creation? Assuming that the Scout Groups are disciplinary spaces, whose goal is the formation of an educated young, aware of their duties and availabilities to society, we reflected on the implementation of the Scout Method, seen in our work as a mechanism whose function is to discipline the body, mind and emotions of the scouts. We also analyzed the symbolic practices that pervade the scouting, responsible for establishing cohesion and sense of belonging among scouts members seeking the construction of a common identity. To achieve this research, it was discussed as some authors, like FOUCALT (1987) and his theoretical reflections on disciplinary power, BOSI (1994) and HALBWACHS (1990) on the memory, HALL (2005) who gave us allowance to discuss the production of identities, Chartier (1990) and his analysis of the social representations, Certeau (1994) on resistance tactics, among others.

Abstract:
碩士<br>國立成功大學<br>測量及空間資訊學系<br>104<br>Towards the Development of IoT-based Emergency Alert Service - An Example of Flood Alert Yu-Sheng Chen Jung-Hong Hong Department of Geomatics, National Cheng Kung University SUMMARY When facing emergency threats from natural hazard (e.g., flood), alert messages must be effectively distributed to the public in advance to avoid or reduce human lives and property loss. By connecting devices in the internet and hosting an interacting mechanism between devices, we argue the Internet of Things (IoT) provides a brand new perspective to the development of automatic alerting systems. With steadily decreasing cost, sensors can be easily and widely deployed at either fixed location of important facilities or places arbitrarily selected for monitoring purposes to continuously generate observations. The proposed IoT-enabled alerting system prototypes have two ways for alert messages transmission: the in-situ broadcasting and the internet alert publication. Once the threshold value is reached, the in-site mode directly broadcasts alert messages to clients in the neighbor, while the internet mode publishes and distributes interoperable alert messages following the CAP standard to the public. Furthermore, the observation data is available via standardized web service following SWE standards, which enables domain experts to develop integrated applications. To improve the accuracy and efficiency of the alert information, we further introduce the expert-driven templates to the automatic generation of alert messages. Comparing to the traditional alert mechanism, the IoT-enabled alert system fully demonstrate its superior capability on the improvement of mobility and wide-coverage of phenomena monitoring, immediate and effective broadcasting, interoperability of alert messages, automatic issuing and processing of alert messages and the potential to become a robust and reliable sources of hazard-related applications. Key words: Internet of Things, Sensor Web Enablement, Common Alerting Protocol, CAP template. INTRODUCTION In recent years, natural hazard has been a major threat to the people, an effective and robust mechanism that can integrate all resources together for reducing lives and property causality should always be given the highest priority. Efforts have been made for predicting incoming threat and issuing early warning to the people within the threaten area, so that have sufficient time for preparation. We believe the emergence of the IoT technology brings a new perspective to the alerting systems due to many reasons. Firstly of all, the price of sensors drops significantly, which allows authorized agencies to widely deploy sensors with relatively lower cost. Secondly, as the number of internet-connected devices dramatically increases, the sensor observation and alert messages can be easily transmitted and distributed. Finally, the trend of open data creates a new resource platform where data from the IoT devices can be shared in an interoperable way. An IoT-enabled architecture for alert systems is proposed in this paper. The design is based on the principles of sensor deployment, message broadcasting, interoperable content and automatic processing. Sensors can be deployed at any chosen places to adapt to different scenario needs. Whenever any emergency situations happen, the alert system automatically detects the threat and issues alerts following the Common Alerting Protocol (CAP) to the people within the impacted area. Via in-situ broadcasting or internet publication, clients are made aware of any threat in their neighborhood. MATERIALS AND METHODS Fig. 1 illustrates the system architecture proposed in this research. After sensors are deployed at important facilities or places that can provide early warning, they can continuously monitor the changing phenomena. Once the observation values reach the specified threshold value, the alerting module is automatically triggered. Two alert modes are developed to adapt to different application scenarios. The in-situ mode broadcasts alert messages to nearby devices via ZigBee. Even without internet connection, the in-situ mode can still supply immediate warning. The internet mode generates CAP-based alerts and distributes the alerts via internet, which enables subscribers to receive standardized alert messages and further develop add-value applications. Meanwhile, the sensor observations are opened accessible following the Sensor Web Enablement standards, which enables the development of cross-agencies collaborative data exchange mechanism. Figure 1. The flood warning system The deployment of sensors plays a major role in the success of the alert systems. Two patterns of sensor deployment are proposed. The fixed-location type is to deploy sensors at preselected locations, normally used for area that has long history of flooding. The mobile type deploys sensors according to the real flood situations, such that the sensors can be flexibly moved to any places with emergence situations. As the monitoring unit can be easily deployed, it offers the flexibility of quick installation and easy adjustment. The basic structure of broadcasting messages is as follows: 〈disaster type〉〈district_code〉〈road_code〉〈sensor type+ serial number〉〈GPS coordinates〉 This standardized design allows the clients to uniquely interpret and identify from which sensor the warning message is sent and automatically transformed to both voice and text message to draw users’ attentions. In addition to the direct warning, the measurement from sensors can be transmitted to the database via Wi-Fi. We develop a cross-platform real-time observation sharing mechanism based on the SWE standards. As various types of observations are accessible via the same standardized web service interface, the cross-agency data sharing becomes much simpler. Authorized agencies can issue alerts following the CAP-TWP to the public based upon the collected observations. To improve the efficiency of generating CAP-TWP alert messages, alert templates are developed according to the operating procedures of issuing alerts and the sensor deployment. The successful use of templates implies most of the alert contents can be determined beforehand and significantly improve the efficiency for generating new alerts. We also develop a map-based website, which provides visual inspection of real-time observations and alert situations. Figure 2. Cross-platform warning architecture RESULTS AND DISCUSSION In this research, we use Arduino to implement the control of the monitoring unit and the broadcasting of alert messages. We use SOS servers in the server sides, which enables to publish observations as a web service. We also use C# and JavaScript to for automatically processing cross-platform sensing data sharing simulation, and implement the CAP templates and different alert modes programming in the experiment. Finally, we host a map based website for real-time observations and the locations of alerts. The following lists the implementation results from the test:  Alert messages are successfully broadcasted to clients to provide early warning.  The monitoring of flooding area is more flexible for different scenarios based on the two types of sensor deployment.  Observations are shared by different agencies following the SWE standards, which enables the development of extended interoperable applications.  The map-based website allows the general public to access real-time observations and locations under threats.  The designed CAP templates and automatic processing mechanism can determine almost 100% of the alert contents. CONCLUSION The IoT technology provides an innovative perspective for the alerting systems. The implemented system prototype successfully broadcasts alerts to nearby devices to get drivers’ or disaster operators’ attention about the coming threat. The two types of sensor deployment offer the flexibility to cover wider coverage and adapt to the continuously changing status in reality. Under the open standards and the IoT coupling architecture, CAP-based alerts can be automatically generated and published. As far as the effectiveness, efficiency and automation are concerned, the IoT-enabled architecture fully demonstrates its potential to revolutionize the future development of alerting mechanism.

Abstract:
Traditional methods for communicating the presence of maintenance activities and work zones have been done with a variety of fixed signs. The increase of in-vehicle connectivity on our roads—either directly integrated into the vehicle or via an application running on a mobile phone–provides an opportunity for additional communication to motorists about the presence of emergency vehicles, maintenance activities, or work zones. Although the exact form of the in-vehicle communication is evolving and will continue to do so, a critical first step is to leverage the extensive telematics currently deployed on the Indiana Department of Transportation Vehicles. The objective of this study was to conduct trial deployments on a variety of INDOT vehicles, and to begin a dialog with private sector partners about what information INDOT can share that will provide a safer roadway for all motorists, INDOT workers, and INDOT partners. The final design of connected vehicles will likely change considerably over the next few years as market forces determine what type of information is directly integrated into the vehicle and what information is integrated via cell phones. This report identifies several examples where in-vehicle notification alerting drivers to the presence of service and contractor vehicles was acknowledged by drivers. Hard braking data is being used to determine if these alerts have a meaningful impact on safety. Early results indicate substantial reduction in hard braking events (from 29 to 3) between conditions when queue trucks are not used and when they are used. A larger data set is currently being collected with Hoosier Helpers to isolate the impact of the in-vehicle alerts.
