“…Drones, or "unmanned aerial vehicle," were initially developed for military purposes, but in the last decade, the use of drones in operations relevant to civilian and commercial areas became common around the world. They have been gradually used in many situations, such as crisis management, medical assistances, and agriculture and forestry management (Martinez-Heredia et al, 2018).…”

Public–private collaborations have the potential to effectively respond to extreme events. However, traditional public–private collaborations that are usually led by governmental actors often encounter significant difficulties in a crisis. Based on a case study of a public–private collaboration dealing with COVID-19 in China, we explore how a private actor emerges as a leader to initiate and manage a public–private collaboration in the crisis, and how stakeholders in this collaboration work together to effectively handle the crisis. The findings indicate critical characteristics and contingencies when a private actor leads the cross-sector collaboration to effectively cope with uncertainties and deliver public services in crisis time.

“…For example, Martinez Herdia et al presented an emergency radio beacon specifically designed to find and recover small UAVs. They carried experiments to show its high precision and endurance [18]. According to Reference [4], UAV can be used in a lot of ITS applications, and there are huge potential and numerous challenges for UAV-enabled ITS for next generation smart cities.…”

“…This phase starts at d c,b = d b,re f + d stop (the vehicle stops, at worst, at the same position as the barrier). Reference braking profiles are given by Equations ( 17) and (18). The speed profile is determined by kinetic energy dissipation model, and the acceleration profile is related to the time derivative of the former.…”

The characteristic pillars of a city are its economy, its mobility, its environment, its inhabitants, its way of life, and its organization. Since 1980, the concept of smart city generally consists of optimizing costs, organization, and the well-being of inhabitants. The idea is to develop means and solutions capable of meeting the needs of the population, while preserving resources and the environment. Owing to their little size, their flexibility, and their low cost, Unmanned Aerial Vehicles (UAV) are today used in a huge number of daily life applications. UAV use cases can be classified into three categories: data covering (like surveillance and event covering), data relaying (like delivery and emergency services), and data dissemination (like cartography and precise agriculture). In addition, the interest to Cooperative Intelligent Transportation Systems (C-ITS) has risen in these recent years, especially in the context of smart cities. In such systems, both drivers and traffic managers share the information and cooperate to coordinate their actions to ensure safety, traffic efficiency, and environment preservation. In this work, we aimed at introducing a UAV in a use case that is likely to happen in C-ITS. A conflict is considered involving a car and a pedestrian. A UAV observes from the top of the scene and will play the role of the situation controller, the information collector, and the assignment of the instructions to the car driver in case of a harmful situation to avoid car-pedestrian collision. To this end, we highlight interactions between the UAV and the car vehicle (U2V communication), as well as between the UAV and infrastructure (U2I communication). Hence, the benefit of using UAV is emphasized to reduce accident gravity rate, braking distance, energy consumption, and occasional visibility reduction.

“…Another effective proposal is to deploy an Air-Ground Collaborative Wireless Network to support SAR teams, with an example operating in hostile alpine environments [47]. In this sense, Unmanned Aerial Vehicles for SAR missions are attracting a high amount of effort from the research community [48], [49], with new algorithms being developed frequently to improve the efficiency of this kind of robots, e.g. the work described in [50].…”

Search and Rescue operations in emergency response to natural or human catastrophes have the main objective of locating and rescuing potential victims as fast as possible, thus quick response and accurate actions being mandatory. While standard communications may be affected, a Wireless Sensor Network can be deployed to support the rescue team. This kind of network allows data acquisition close to events and enable persistence over time, among other advantages. However, to adapt to the requirements of this kind of scenario, enhancements must be made. This work presents two Hybrid Wireless Sensor Networks, based on ZigBee and LoRa, developed to address some of the challenges that Search and Rescue operations pose to the use of Wireless Sensor Networks, and tested in realistic scenarios in cooperation with first responders. Likewise, several software developments that increase the performance of the networks are described. Finally, the conclusions presented, and the lessons learnt are supported by a high amount of data, gathered in realistic exercises in cooperation with civilian and military first responders.INDEX TERMS Graphical user interfaces, Mobile robots, Search and rescue, Emergency services, ZigBee, LoRa, Internet of things.
