“…Fixed-wing were prevalent for traffic monitoring applications a few years ago [75], but today small rotarywing are preferred [11] due to the fact that they are low-cost and require less experience and training [64]. The first type of UAV have some advantages, e.g., increased flight endurance [53], faster travel and ability to carry heavier payloads [51], and ability to fly along linear distance [62], but they are larger in size and depend on airfield for takeoff [96]. Rotary-wing UAVs are lighter in weight, capable for vertical take-off and landing (VTOL), provide significant advantages in enclosed or constrained environments [43], and are capable to hover and to get very close to objectives [62], providing very high spatial resolution [64].…”

Unmanned aerial vehicles (UAVs) are gaining considerable interest in transportation engineering in order to monitor and analyze traffic. This systematic review surveys the scientific contributions in the application of UAVs for civil engineering, especially those related to traffic monitoring. Following the PRISMA framework, 34 papers were identified in five scientific databases. First, this paper introduces previous works in this field. In addition, the selected papers were analyzed, and some conclusions were drawn to complement the findings. It can be stated that this is still a field in its infancy and that progress in advanced image processing techniques and technologies used in the construction of UAVs will lead to an explosion in the number of applications, which will result in increased benefits for society, reducing unpleasant situations, such as congestion and collisions in major urban centers of the world.

“…Guidelines on how to gain access to sites including the identification of take-off and landing areas will have to be made available to the network of UAS pilots. On the go detection of take-off and landing areas could also aid in flood emergency responses (Popescu & Ichim 2016;Shah Alam & Oluoch 2021). Providing near real time, information about the flood extent, could improve emergency response provision during an event, for example, in detecting stranded people and pointing out possible evacuation routes.…”

Preparedness for flood emergency response is crucial for effective flood management. The need for advanced flood decision support tools that aid flood management has been recognized by several authors. This work examines the variability that currently exists across England with regard to the Unmanned Aerial System (UAS) data collection and processing strategy in flood emergency events. Expert elicitation was carried out using a tailored questionnaire about UAS deployment in three flood emergency scenarios. The survey highlighted that reduced equipment assembly time, a national network of appropriately qualified UAS pilots and the effective UAS deployment when on-site, can reduce the response time to flood emergency. For improved comparability and reduced bias in data collection and interpretation, clear guidelines on which data products are most beneficial for particular purposes, processing time required, platform and sensor selection may also be necessary. We consider that releasing a comprehensive documentation pack, which includes guidelines, standards and protocols that detail the methods, tools, technology, quantity and quality of data, to UAS pilots on a flood emergency call, will enhance the timely response.

“…Likewise, computer vision processing was used to analyze and find features on input data [21][22][23][24]. Image analysis was studied and generated specialized datasets to perceive the environment, such as NYU Depth Dataset V2 [25], KITTI [26], and Cityscapes [27].…”

Increasingly, robotic systems require a level of perception of the scenario to interact in real-time, but they also require specialized equipment such as sensors to reach high performance standards adequately. Therefore, it is essential to explore alternatives to reduce the costs for these systems. For example, a common problem attempted by intelligent robotic systems is path planning. This problem contains different subsystems such as perception, location, control, and planning, and demands a quick response time. Consequently, the design of the solutions is limited and requires specialized elements, increasing the cost and time development. Secondly, virtual reality is employed to train and evaluate algorithms, generating virtual data. For this reason, the virtual dataset can be connected with the authentic world through Generative Adversarial Networks (GANs), reducing time development and employing limited samples of the physical world. To describe the performance, metadata information details the properties of the agents in an environment. The metadata approach is tested with an augmented reality system and a micro aerial vehicle (MAV), where both systems are executed in an authentic environment and implemented in embedded devices. This development helps to guide alternatives to reduce resources and costs, but external factors limit these implementations, such as the illumination variation, because the system depends on only a conventional camera.
