Economic and Legal Bases of Using Car-Sharing Business Models in Ukraine

et al. 2020

This article summarizes the concept of sharing, bibliographic analysis of publications in the field of car-sharing based on the Scopus database. The primary purpose of the study is to study the economic and legal basis for the development of car-sharing business models in Ukraine. Systematization of literature sources and approaches devoted to the economic efficiency of the implementation of car-sharing business models has shown that in Ukraine, this issue is almost not paid attention to in the economic, scientific sphere, and legal, scientific areas. The urgency of solving this scientific problem lies in the need and ability to relieve road traffic from traffic jams, reducing the average downtime of vehicles, as well as economic benefits for entities (vehicle owners and passengers) involved in sharing business models. The research has the following logical sequence: the types of car-sharing business models were analyzed, and their comparative characteristics were carried out; the economic and legal preconditions of car-sharing business development in Ukraine are investigated. The research identifies legislative obstacles to the establishment of a car-sharing company in Ukraine. A SWOT analysis of the conditions for implementing a car-sharing business model in Ukraine was performed. It analyses the costs and efficiency of creating a business based on a car-sharing business model in Ukraine on a conditional example. We propose to use system-structural and comparative analysis to analyze the problems of modern transport, methods of formal-logical analysis for determining the directions of development of car-sharing business models, and economic method for assessing the effect and a payback period of the proposed project car-sharing business model. The study results can be useful for the development of the car-sharing business in Ukraine, for entrepreneurs, scientists, and vehicle owners. Keywords: car-sharing, car-sharing business model, car-sharing business, motor transport, hire, expenses, analysis.

The problems of traffic management in large cities are complicated as the increase in traffic volume far exceeds the road network capacity. It leads to saturation of the road network, which negatively affects its functioning. This article analyzes the state of the art of improving the quality of road traffic by predicting the size of traffic after the implementation of traffic management measures. While the issue of modeling traffic flow parameters based on technological factors has been sufficiently studied, the problems of considering the human factor need to be clarified. The object of study is traffic flow on the city's road network. The criteria used by drivers to compare the characteristics of alternative traffic routes were identified based on the field study results. Based on the data obtained, the parameters of alternative routes that drivers choose when driving on the road network are formed. According to the survey results, the most significant factor is the minimum mileage along the route. Deviations from the shortest route were determined to determine the patterns of distribution of correspondence of non-route vehicles along alternative routes. It made it possible to define the distribution of transport correspondence along alternative routes. Since the process under consideration is probabilistic, the law of distribution of a random variable was determined. After having determined the law of distribution of a random variable for the data obtained, the calculations showed that the change in the random variable is well described by the gamma distribution. It was determined that the share of transport correspondence that will be carried on them decreases as the length of the route deviates from the shortest one. The obtained results make it possible to predict road network congestion by modeling the distribution of traffic flows. In further research, it would be advisable to analyze the distribution of transport correspondence by other criteria.

The development of road transport, both economically and socially, is of great importance for humanity. But along with the tremendous benefits andunlimited potential of road transport, there are many problems, particularly with its operation in human settlements, particularly in cities. Theseproblems are related to the oversaturation of the road network of cities with road transport, which leads to a decrease in speed, congestion, increased traveltime. Ensuring the required capacity of the site is the main indicator of creating conditions for the efficient functioning of the transport system of cities.Each section has its own planning features that allow the car to move at an acceptable speed and at the same time not create any situations that could lead to the formation of congestion.It is known that the lower the speed, the greater the time spent. Speed is one of the most important indicators of traffic flow. Any reduction in the speed of traffic flows compared to the permitted leads to economic losses. And if we consider the reduction of speed, taking into account the stop in motion (delay), it leads to much greater economic losses.
