The number of autonomous vehicles in use has been increasing. A growing number of companies invest in the development of algorithms that allow users to rely on intelligent systems to avoid accidents, park their vehicles or, even, hand over the navigation of their vehicles. Driver vulnerabilities, such as fatigue, emotional driving, violation of traffic reg ulations and slow reflexes, often lead to accidents. In contrast, the fast response time of autonomous vehicles alongside compliance with traffic regulations promise, according to existing literature, a significant drop in the number of such accidents. For this reason, the market moves towards autonomous vehicles. Autonomous vehicles are equipped with sensors which provide a variety of in formation about their environment. A new opportunity thus arises with regards to vehicle interactions with information of the road infrastructure. This has given rise to a new research field exploring the Internet of Vehicles (IoV), including vehicle to-vehicle (V2V) communication and vehicle-to-infrastructure (V2I) communication. The former concerns vehicle communication, whereby each vehicle reports its status and intentions to nearby vehicles. The latter, which is the focus of this diploma the sis, concerns communications between each vehicle with a central server in the road infrastructure. This information, after being processed, may be sent to the users of the road network to aid the navigation of vehicles. Crowd sourcing (CS) applications, such as Google Maps, monitor road traffic in real time and allow the development of methods for the effective interconnection of a source with the server. These methods take into account the size of information that each source must send, the structure used to process the data, the security of user data and the robustness of the system. In this diploma thesis, CS methods are used in autonomous vehicles for the structuring of data layers on a map (GIS layers). In particular, information is being extracted by LiDAR sensors as to the existence of free parking spaces or parked cars and is used to inform the users in real time as to the availability of parking spaces. This was implemented using a CARLA simulator that simulates an urban environment. Python programming language in the ROS ecosystem was used for the processing of vehicle sensor data. The processed data were sent and accessed via the MongoDB database and the visualization of information on a map was implemented through QGIS software.
