    The future of the world's population concentration lies within the bounds of urban cities. Citizens, or humans, are the most important tangible resources in a smart city environment, and they need to be served as well as protected. The concept of smart cities is trying to accomplish the idea of serving the citizens by leveraging the potential of information and communications technology assets. Citizens have access to smart technologies and applications, and thus they form an indispensable component to complement and supplement a smart city's operation. Especially in humanitarian assistance and disaster recovery (HADR) operations, where a smart city's core infrastructure might be compromised, the assets of citizens can be put to use. This article aims to describe the current state of affairs for safety in cities and humanitarian assistance in emergency situations, which require leveraging situational awareness data. We discuss and propose mechanisms for connecting to and utilizing crowdsourcing and crowdsensing data in a smart city environment, which can assist in efficient HADR operations

    A situational awareness framework for improving earthquake response, recovery and resilience

    When we think of understanding the impact on the buildings of a city from an earthquake we imagine structural engineers assessing structures and the local area through measurements and readings. However, the access to such areas is not always straightforward and nor is it necessarily possible to have enough manpower to complete these analyses. Instead, crowdsourcing and smart sensors can be utilized in both the pre and post disaster phases using information witnesses to give enhanced situational awareness to those coordinating the earthquake response effort. Even in remote areas many people have access to smartphones, wearable technology and mobile internet access. Furthermore, with the advent of smart cities, further sensors can be placed strategically on infrastructure and transmit information about its structural health. Dedicated mobile applications can be used to capture reports, photographs and videos of vulnerable infrastructure before and after an earthquake. These photos and reports can then be mapped to identify areas where structures or critical infrastructure are most at risk or where other secondary effects may occur. This can be done before sending in expensive manpower to areas that may not yet be safe. Moreover, those who are submitting information do so in the knowledge that they are contributing to a faster and more efficient response, providing vital information about where resource can be most effectively used, and, in return, closing the intelligence loop, receive situational awareness information about their immediate environment. We present an initial situational awareness framework for earthquake management that encompasses the preparedness, response and recovery phases. It is envisaged that this framework will help develop more effective risk assessment and management frameworks for structures and critical infrastructure (e.g. industrial facilities)

    Ensuring high quality public safety data in participatory crowdsourcing used as a smart city initiative

    The increase in urbanisation is making the management of city resources a difficult task. Data collected through observations of the city surroundings can be used to improve decision-making in terms of manage city resources. However, the data collected must be of quality in order to ensure that effective and efficient decisions are made. This study is focused on improving emergency and non-emergency services (city resources) by using Participatory Crowdsourcing as a data collection method (collect public safety data) utilising voice technology in the form of an advanced IVR system known as the Spoken Web. The study illustrates how Participatory Crowdsourcing can be used as a Smart City initiative by illustrating what is required to contribute to the Smart City, and developing a roadmap in the form of a model to assist decision-making when selecting the optimal Crowdsourcing initiative. A Public Safety Data Quality criteria was also developed to assess and identify the problems affecting Data Quality. This study is guided by the Design Science methodology and utilises two driving theories: the characteristics of a Smart City, and Wang and Strong’s (1996) Data Quality Framework. Five Critical Success Factors were developed to ensure high quality public safety data is collected through Participatory Crowdsourcing utilising voice technologies. These Critical Success Factors include: Relevant Public Safety Data, Public Safety Reporting Instructions, Public Safety Data Interpretation and Presentation Format, Public Safety Data Integrity and Security, and Simple Participatory Crowdsourcing System Setup

    A review of the internet of floods : near real-time detection of a flood event and its impact

    Get PDF
    Worldwide, flood events frequently have a dramatic impact on urban societies. Time is key during a flood event in order to evacuate vulnerable people at risk, minimize the socio-economic, ecologic and cultural impact of the event and restore a society from this hazard as quickly as possible. Therefore, detecting a flood in near real-time and assessing the risks relating to these flood events on the fly is of great importance. Therefore, there is a need to search for the optimal way to collect data in order to detect floods in real time. Internet of Things (IoT) is the ideal method to bring together data of sensing equipment or identifying tools with networking and processing capabilities, allow them to communicate with one another and with other devices and services over the Internet to accomplish the detection of floods in near real-time. The main objective of this paper is to report on the current state of research on the IoT in the domain of flood detection. Current trends in IoT are identified, and academic literature is examined. The integration of IoT would greatly enhance disaster management and, therefore, will be of greater importance into the future

    Real-Time Urban Weather Observations for Urban Air Mobility

    Cities of the future will have to overcome congestion, air pollution and increasing infrastructure cost while moving more people and goods smoothly, efficiently and in an eco-friendly manner. Urban air mobility (UAM) is expected to be an integral component of achieving this new type of city. This is a new environment for sustained aviation operations. The heterogeneity of the urban fabric and the roughness elements within it create a unique environment where flight conditions can change frequently across very short distances. UAM vehicles with their lower mass, more limited thrust and slower speeds are especially sensitive to these conditions. Since traditional aviation weather products for observations and forecasts at an airport on the outskirts of a metropolitan area do not translate well to the urban environment, weather data for low-altitude urban airspace is needed and will be particularly critical for unlocking the full potential of UAM. To help address this need, crowdsourced weather data from sources prevalent in urban areas offer the opportunity to create dense meteorological observation networks in support of UAM. This paper considers a variety of potential observational sources and proposes a cyber-physical system architecture, including an incentive-based crowdsensing application, which empowers UAM weather forecasting and operations
