The goal of smart cities and sustainable transport is to ensure the efficient movement of people while minimizing a negative impact on the environment. Many cities around the world conduct a policy aimed at limiting parking spaces; however, the complete elimination of parking spaces in cities currently does not seem possible. Parking vehicles cause disturbances in road traffic by searching for a parking space and performing the parking maneuver. This article analyzes the impact of the parking maneuver on the capacity of the inlets of intersections with traffic lights, and the significance of the time it takes to enter and exit a parking space on road traffic disturbance areas under Polish conditions. The research is carried out in on-street parking, characterized by different positions of the parking space to the road, the different surfaces of parking spaces, and the geometry of the road next to which the parking spaces are located. Differences in the time of entry to and exit from the parking space between the research areas indicate that different characteristics of the parking spaces affect the time of the parking maneuver. Drivers wait for the acceptable distance between vehicles on the road into which the vehicle can exit from the parking space. Drivers exiting from perpendicular parking spaces more often cause traffic disruptions than in the case of parallel parking spaces, due to limited visibility. The occupancy of parking spaces directly next to the analyzed ones also affects the time of entry to and exit from the parking space. However, between the time of entry to or exit from the parking space, and the use of the parking space, there is no relationship. This finding indicates that more factors determine the time of entry to and exit from the parking space. The results presented in the article show the need to conduct further research on the impact of parking maneuvers on the capacity of intersections with traffic lights for road traffic conditions in Poland. The results of the research will allow for the design and construction of an optimal parking infrastructure that will meet the needs of road users, while minimizing the negative impact on road conditions and the natural environment following sustainable development.

One of the most important components of the territorial socio-economic complex of a city (especially a large one) is the system of urban passenger transport, which, in turn, consists of two subsystems: urban public transport and personal vehicles. In 2000-2020. many large and medium-sized cities in Russia are going through a period of active motorization. Izhevsk is no exception in this regard. The level of motorization of the population has been increasing in recent years both in the city and in the Udmurt Republic as a whole. There is a growing need to reduce the flow of personal vehicles towards more active use of public transport. Urban public transport (for all its significant scale) has, as a rule, 2-3 owners and therefore is largely manageable, which cannot be said about personal vehicles. It is not possible to force car owners to switch to public transport by order. But it is possible to create such conditions when the resident himself does not use his own car, but gives preference to public transport. For example, to organize the work of a single parking space, in which the placement of paid parking lots will make it unprofitable to visit many of the most attractive objects (especially in the central part of the city) by private vehicle. An example of such relevant work is shown in the proposed article. By order of the Administration of Izhevsk, the authors of the article have identified the most optimal locations for paid car parks. The choice was determined based on the results of step-by-step work to assess: the location of the potential of Izhevsk public transport, the intensity of traffic flows, the density of the population, the availability of existing parking areas, points of attraction for vehicles.

Shared autonomous vehicles (SAVs) are a major development direction in international scientific and technological innovation. One of the most popular features of SAVs in the urban space is that they can significantly reduce the need for parking. The urban underground parking space (UPS) is currently the largest static traffic space, especially in high-density urban centers. Under the SAV scenario, the need for the renewal of UPS will increase in the near future. However, renewal of the UPS is difficult due to its special form features, which are greatly restricted by the external environment, thus necessitating targeted methods and strategies. This research first conducted field investigations and data collection on the spatial morphology and service conditions of typical UPSs in different areas of Hangzhou city. Based on the driver status response and the multi-objective attribute models, the time-series evaluation method and function replacement decision model for the sustainable renewal of underground parking were established. The research also discusses appropriate design strategies for the combination of spatial characteristics and functional replacement goals of typical samples. The conclusions will provide scientific guidance for the future design practice of architects and urban designers in SAV.

<p>The existing parking area at Sultan Hasanuddin Airport Makassar has 675 four-wheel parking areas, which cannot accommodate about 10 million passengers in 2013 and every year there is an increase. This study aims to analyze the characteristics of parking, especially the handling of four-wheeled vehicles in the parking building from entry, dropout, pickup, maneuver, clearance, vehicle rotation and parking slots to exiting the building. Analyze the parking area related to the level of safety and ease of use of parking buildings, especially on the semi-basement floor at Sultan Hasanuddin Airport. The method used for this research is a qualitative method, namely research that is descriptive and tends to use analysis from the data that has been collected and direct observation on the existing parking building at Sultan Hasanuddin Airport Makassar. The data collection process was carried out in two stages, namely the preliminary survey and the main survey. The results of research and observations of the existing parking building at Sultan Hasanuddin Airport, especially on the basement floor, show that the construction of a parking building that was built in terms of size, height clearance, slope, parking space layout, facilities are in accordance with the minimum standard of parking buildings, but there are some works such as sidewalks. and a stopper whose placement reduces the parking area and vehicle circulation.</p>

The existing automatic parking algorithms often neglect the unknown obstacles in the parking environment, which causes a hidden danger to the safety of the automatic parking system. Therefore, this paper proposes parking space detection and path planning based on the VIDAR method (vision-IMU-based detection and range method) to solve the problem. In the parking space detection stage, the generalized obstacles are detected based on VIDAR to determine the obstacle areas, and then parking lines are detected by the Hough transform to determine the empty parking space. Compared with the parking detection method based on YOLO v5, the experimental results demonstrate that the proposed method has higher accuracy in complex parking environments with unknown obstacles. In the path planning stage, the path optimization algorithm of the A ∗ algorithm combined with the Bezier curve is used to generate smooth curves, and the environmental information is updated in real time based on VIDAR. The simulation results show that the method can make the vehicle efficiently avoid the obstacles and generate a smooth path in a dynamic parking environment, which can well meet the safety and stationarity of the parking requirements.
