In the contemporary world, due to the rapid growth of cities and the population as a whole, the number of personal vehicles is increasing. But at the same time, the infrastructure, especially in the old areas of towns, is not being modernized, and in such areas parking is not provided at all or is not designed for an ever-increasing number of cars. Due to the lack of parking spaces, drivers often leave their cars on the edge of the roadway, thereby reducing even more the already small capacity of the road. Also, especially in large cities, a common reason for such parking is the high cost of parking, low level of service and security, and the long time of the vehicle parking process itself. This article examines the experience of foreign countries in solving the problem of parking along the roadway: what technologies are used to create parking lots, what tasks are set by designers to achieve the best result and improve the urban environment. The authors cite the works of Russian companies engaged in the design of parking lots, and note what tasks Russian companies set themselves. The differences between the approaches of Russian designers and their foreign colleagues to the problem of parking are also presented. The article analyzes the locations of objects that Russian design companies have worked on, the situation with parking in large cities and in smaller ones. Taking into account the peculiarities of parking design in Russia, the article suggests a way to improve the situation with spontaneous parking – the introduction of automated control systems. The advantages of implementing automated systems both on the part of the car owner and on the part of the parking lot owner are described.

The bi-fuel system vehicle (gasoline/LPG) has been developed for a long time because it has the ability to switch fuels, both built as an original equipment manufacturer (OEM) or as a modified vehicle. However, on vehicles with planetary automatic transmissions, additional control systems are needed to produce optimal performance, both on gasoline and LPG operations, especially on uphill roads. Old vehicles with planetary automatic transmissions are not equipped with road slope angle sensors, so on uphill roads and the driver has not mastered road conditions, the engine tends to stop suddenly. Therefore, this study aims to develop a fuel control system (LPG operation) on a planetary automatic transmission to control gear shifts based on the level of the road slope. A simulation with MATLAB Simulink we used to create a control system, with objective function and constraint defined. As a result, the control system can recognize the level of the road slope to control the speed gear shift. This control system is promising and reliable to be implemented in real conditions.

Modern trends in construction in large cities and megacities, lack of available land, rising land prices and the need for its rational use lead to the active development of underground space. Construction of underground garages, Parking lots, shopping centers, pedestrian crossings and transport tunnels requires the use of reliable (waterproof) and durable waterproofing Bentonite slabs are widely used in construction, for example, in waterproofing. The material has been in use for a long time, because its main component is clay. One of the famous and already outdated varieties of material is found under the name "clay castle". It is a compacted paremata in plate raw material, whose thickness was 30-40 cm Today, technology has leaped forward, incorporating the best of old techniques and modern developments. So there were bentonite mats, which will be discussed further.

In downtown areas of large cities, it is very challenging for drivers to find available parking spots, even when they are provided with information on parking availability and location information. To overcome this challenge, this paper develops a dynamic vehicle routing system to search for the optimal routes for connected vehicles to find parking spots successfully and to minimize total trip time, including driving time and walking time. The system predicts the probability of each parking lot having available parking spots based on the existing available number of spots and the vehicle arrival and departure rates collected by connected vehicles. This probability is integrated in the search for vehicle routes to minimize total travel and walking times. Numerical experiments indicate that the proposed system can reduce the cruising time spent searching for available parking spots, and the total trip time can be reduced by up to 24%. In addition, the system can decrease the number of re-routing decisions, which reduces the stress of drivers on the road. A sensitivity analysis of the parking probability is also conducted. Some future work based on the proposed system is proposed in the conclusion to this paper.

The article considers automated traffic flow control systems, their classification and description. Based on the above, it can be argued that traffic control systems have the characteristics of distributed, discrete and non-stationary complex systems used to solve traffic control problems by modern means of information and computer technology. The object of research is to improve traffic control with the help of automated control systems Purpose - analysis of automated traffic management systems With the rapid growth of the car fleet, there is an overload of the street and road network of cities. Even today, the street and road network does not meet the requirements for the organization and safety of road traffic. A survey of traffic flows shows that the road network operates at the capacity limit, and in some places exceeds this limit. The main reason for this transport situation in cities is the mismatch between the level of motorization and the density of the road network. Therefore, to improve, improve traffic control, it is proposed to use automated traffic management systems. But first you need to analyze them in detail. It is noted that the efficiency of the street and road network depends entirely on the effective balanced operation of all its elements. KEYWORDS: CAR, AUTOMATED SYSTEMS, ROAD TRANSPORT MANAGEMENT SYSTEMS, TRANSPORT NETWORK, TRANSPORT FLOW.

In the article various variants of the decision of such acute problem, as shortage of parking places in system of a city infrastructure are considered. The necessity and expediency of constructing high-speed mechanized car parks for cars is caused by the acute problem of temporary and permanent storage of vehicles in the conditions of large cities, in places of intensive human flows such as the central part of the city, supermarkets, railway stations, shopping centers, as well as business centers and residential sector cities. To date, most of the real estate (residential buildings, hotels, offices, shopping and entertainment and multifunctional centers) are built with standard parking spaces. During the operation of such standard parking lots, the developer understands that the number of cars exceeds the number of parking spaces provided in the parking lot. The shortage of parking spaces and free parking areas significantly increases the importance of the construction and arrangement of multi-level parking lots. The system of high-altitude automatic parking lots offers a serious alternative to the generally accepted ideas about parking of vehicles [1].

Nowadays, parking spaces are scarce resources in urban cities. Travelers often spend too much time looking for available parking spaces, which increases travel time of travelers and results in additional traffic congestion. With the innovation and application of intelligent parking technology, parking spaces can be booked in the system in advance through mobile phone, which will greatly reduce the time for drivers to cruise and search for parking spaces. Targeted at the serious waste of parking resources, traffic congestion caused by too intensive parking demand in time and space, a parking allocation model considering the ability of dynamic and static traffic conversion is established with the goal of minimizing the total travel time of the travelers. Based on the dynamic traffic distribution model, considering the constraints of capacity of the road link, parking lot entrance and the number of the parking spaces in parking lot, the dynamic and static traffic is combined by considering the parking lot connection section as a conversion link to be added into the traffic network. And the solution method based on particle swarm optimization is proposed. Experimental results on a case (Beijing Chaoyang Joy City and surrounding parking lots) show that our parking allocation model works satisfactorily by effectively reducing the travel time of travelers and increase customer arrivals in shopping centers. From the point of view of traffic managers, the model can make the parking occupancy of all parking lots more balanced, which indicates that the model can help to better coordinate the available parking resources. In summary, the model proposed in this paper can not only divert the flow beyond the capacity of the road facilities at the connection of the parking lot, but also balance the utilization rate of the surrounding parking resources and reduce the dynamic traffic pressure, it is a proper way to develop the sustainable transportation.

To obtain reliable data on the properties of liquid metal and create automated control systems, the technological process of molding with crystallization under pressure is studied. A mathematical model of the input and output process parameters is developed. It is established that the compressibility of the melt can represent the main controlled parameter influencing on the physical-mechanical properties of the final products. The obtained castings using this technology are not inferior in their physical and mechanical properties to those produced by forging or stamping.
