### Synergies and Potential between Automated Vehicles and Smart Cities
The efficient use of parking spaces has a direct impact on traffic flow, quality of life for residents, and the environment. Smart cities are equipped with sensors that monitor the availability of parking spaces in public car parks and on streets. These sensors collect a lot of data and exchange it with cars and the smart city itself. The information is, for example, about which parking spaces are available and which are occupied, and this information is then shared with autonomous vehicles, which can search for the appropriate parking space accordingly. It should be added that thanks to such an intelligent parking system, it is possible for the cities to also make more money for the budget because intelligent parking systems can also adjust parking prices based on supply and demand. This means that, for example, at the busiest times, parking prices will be more expensive, forcing people to look for cheaper spaces, for example, outside the center, and forcing them to use transport or park only briefly. Of course, even such rules would recognize exceptions in the form of free parking spaces for the disabled and so on. Moreover, intelligent parking systems analyze parking usage data and predict future parking demand based on history and trends. This data can help cities, especially when planning future infrastructure. For example, they can take into account the need to build more free catchment car parks and strengthen public transport to relieve parking congestion in city centers. This will allow commuters to combine different modes of transport according to their needs and preferences. Optimizing parking in smart cities contributes to more efficient use of public spaces, reduces traffic in search of parking spaces, and improves the overall traffic flow. These systems also increase driver convenience and reduce the negative impact of car traffic on the environment and quality of life in the city [42]. Following the above, it is inevitable that the synergistic potential of this combination will manifest itself in the end, mainly in the form of reduced emissions and pollution in smart cities. This will ensure more sustainable and healthier living environments for their residents. Automated vehicles, integrated into intelligent transport networks that optimize vehicle flow, ensure that vehicles move around the city efficiently and quickly. This reduces the amount of time vehicles spend in traffic and also reduces emissions. Smart cities contain a number of sensors that monitor air quality. They collect this data from different parts of the city, then analyze and evaluate it, and with this data, smart cities can redirect traffic where appropriate as part of traffic optimization and long-term sustainability. By collecting data on a regular basis and from a large number of users, smart cities are able to use this data to create personalized transport solutions for residents. These solutions can include route recommendations, travel times, and information on available transport services. Such recommendations would take into account current traffic, preferred modes of transport, travel times, and other factors, improving the efficiency and convenience of travel. Based on data from automated vehicles, smart cities can also predict and optimize travel times for individual residents. These optimized times can include recommendations for optimal departure times, travel during less congested times, and other strategies to minimize time spent in traffic [43]. Figure 3 confirms our assertions, where it is evident that this autonomous vehicle market is growing; where it is worth approximately USD 41.1 billion this year, it will already be worth over USD 114.5 billion in 2029.
