Abstract. The paper reviews a relevant problem of providing a higher quality of people's living in the northern regions by the application of the modern technologies within transport in order to improve its environmental performance and efficiency. The aim of the research is to substantiate methods of increasing the adaptability of vehicles to variable low-temperature operating conditions based on a neural control system of preheating and maintaining the optimum temperature of technological fluids by SHF radiation and improving diesel fuel properties by introducing a multifunctional additive. It has been found that SHF radiation influences the physical and chemical parameters of diesel fuel, as well as the engine output parameters. SHF radiation results in a reduction of fuel consumption to 7%, smoke from the exhaust to 15%, and nitrogen oxide emission to 30%. A conclusion is made that using SHF radiation for technological fuel preheating is essential. An approach has been developed that improves low-temperature properties of diesel fuels and increases engine operation efficiency under severe climatic conditions by introducing a multifunctional additive. The additive will enable a significant decrease in fuel consumption under low-temperature operating conditions and a complex improvement of fuel properties.

This research is a comparative assessment of the operation of dual fuel engine vehicles (gas-diesel and diesel cycles) in the context of the fuel's environmental impact and economy. The influence of air temperature and vehicle load on this process is considered. The theory of constructive analogy as an example of natural gas vehicles is taken into account. The vehicles mentioned above were comparatively analyzed according to their level of adaptability to low ambient temperatures in the context of fuel consumption and exhaust gases emissions. The regularities of the influence of low ambient temperatures and cargo weight on fuel consumption and the harmful substances emitted with the exhaust gases of natural gas vehicles were determined. In the range of negative air temperatures, the consumption of diesel fuel increased in comparison with a consumption of natural gas to 9%, and at positive temperatures, the consumption of gas increased up to 3%. Decreasing air temperature and cargo weight reduced the mass emissions of soot and the nitrogen oxide emitted with exhaust gases during operation, both on the diesel and gas-diesel cycles. Soot emissions decreased to 26% and nitrogen oxide to 54%. The specific emissions of harmful substances emitted with exhaust gases per unit of fuel consumed for vehicles when operating on the gas-diesel cycle (GDC) is 14…33% less than on diesel. When the ambient temperature falls to −38°C, the vehicle adaptability by fuel consumption when operating on the GDC increases on 6…18% in comparison with a diesel cycle. The vehicles' adaptability, assessed by harmful substances emitted with exhaust gases, to changes in cargo weight are almost identical.

Transport service of the population is a difficult task. The efficiency of transportation processes depends on the road traffic organization. The road traffic organization requires modern approaches to solve the tasks and emerging problems. The concept «Lean Six Sigma » could be one such approach, which will be new tool to solve the road traffic organization problems. The article describes the example of improving the road traffic organization with using the concept of «Lean Six Sigma» on the street and road network section. The used tools in each phase of the «Six Sigma» project life cycle are listed.

The paper presents the results of calculations aimed at improving the organization of road traffic and increase road capacity by installing calling devices at pedestrian crossings. Methods of development and effective functioning of the road network of the city of Tyumen
