The article provides an analysis of the global trends in the field of city transport systems’ safety. Currently, the efforts to increase the proportion of trips made by foot or by non-motorized transport are being made. That is why the problem of ensuring safety of the most vulnerable road users is relevant. The statistics of traffic accidents with victims, as well as the factors that cause such accidents, is analysed. Simulation has shown that rational management can reduce the likelihood of road traffic accidents.

The twentieth century, which became a period of unprecedented growth of cities and urbanization, revealed the need of mankind to develop and implement the principles of sustainable development. Possible ways to shift to sustainable transport system (such as the use of alternative fuel and transition to public and non-motorized modes of transport) are discussed in this article. The objective of this publication is to assess efficiency of such methods’ implementation on the example of the concrete city. Authors have suggested to change the bus route network, the structure of the bus fleet on the routes and to replace public transport buses by the new ones run on methane. To check these suggestions, authors have built the new one transport model and have simulated three cases: the existing route network and bus fleet’s structure, the proposed new one route network with buses run on diesel fuel and the proposed new one route network with buses run on methane. To evaluate efficiency, authors have assessed economic efficiency, positive social effect, environmental friendliness and sustainability of the urban transport system. Economic efficiency is achieved by reducing overruns and fuel costs thanks to the use of buses run on methane. The social effect is in the reduction of: 1) the delivery time by the route network optimization, 2) the likelihood of traffic jams, and 3) the downtime of buses at the bus stops. Since congestions increase pollutant emissions, route network optimization reduces negative impact on the environment. Replacing public transport buses by the new ones run on methane gives the same positive effect. To assess sustainability of the urban transport city is the most difficult task. The authors have identified indicators and used the radar map to compare possible solutions.

The article is devoted to the increase of the cargo vehicles market on the gas-engine fuel. The article considers the relevance of the use of the alternative types of transport’s fuels. As potential energy carriers for internal combustion engines, gas engine fuels are considered. Prospects and problems of using natural gas as motor fuel, as well as ecological and economic aspects of the use of compressed natural gas as fuel for vehicles are presented. Prospects for expanding the market for trucks powered by gas engine fuel are discussed, as well as the advantages of using natural gas as a safe, environmentally friendly and economical type of alternative fuel are considered. It is shown that the main obstacle to the expansion of the gas engine vehicles’ market is the underdevelopment of the infrastructure: filling stations and service centres. The organization of gas-cylinder vehicles (GCV) servicing is considered. The authors have developed an imitation model that allows determining the optimal number of repair stations for the service centre, as well as software for forecasting the required number of automobile gas filling compressor stations (AGFCS).

Traditionally, besides personal vehicles, individual passenger transportation is carried out by taxi services. These services have both positive sides, such as, for example, door-to-door delivery and comfort, as well as negative sides, such as the high cost of the trip. On the one hand, the services, such as Uber and Gett, attract customers with the help of low prices, but, on the other hand, they have a number of disadvantages, the main of which is the problem concerning transportation security. In addition, it must be mentioned that the usage of individual transport is often associated with incomplete load of vehicles, which causes an additional negative impact on the environment as well as on the road network. This article presents a decision support system for taxi dispatch services based on the model of optimal route choice. Optimization is carried out with the help of multifactor analysis of transportation requirements and selection of the optimal route in accordance with given priorities. Such a system will reduce the cost of transportation through the selection of fellow travelers as well as a negative impact on the environment by using a mobile application.

Transport system is the key indicator of sustainable spatial development, because if it is ineffective it can render the economy, the environment, and society vul-nerable. Despite the large number of already existing research, the city transportation sys-tem’s development strategy design is still a relevant objective, because the existing ways and strategies of the transport development may not always be applicable in certain cir-cumstances. This article presents the possible ways of improvement of sustainability of the city transportation systems adapted in accordance with the peculiarities of Russian cit-ies. It is stated that when working out a city transportation system’s development strategy it is necessary to take into account all possible risks. According to the case study of Na-berezhnye Chelny city, all vulnerabilities of the system that today are typical almost for all Russian cities were analyzed, classification of risks was made, and means of their con-trol were suggested. Solutions proposed as a result of the SWOT-analysis can be used when developing transport strategies for other cities with similar specificity.
