The development of the transport network affects the socio-economic development of the territory and it is one of the most important factors in the growth of the level and quality of the population life. There is the need for a study of transport acces sibility. In our work, we presented the mapping and assessment of changes in transport accessibility after the construction of service road. After the construction of the ESPO pipeline, a service road was built along it to maintenance the pipeline, which is located close to the district centers and crosses the local roads. This new road connected them into one network with year-round traffic. The object of our research is the Area of Oil and Gas Extraction in the Republic of Sakha (Yakutia) and the North Irkutsk region.We have created transport accessibility maps with and without all service roads, separately for winter and summer seasons. We have created maps for several district centers. We calculated transport accessibility using the method of constructing iso chrones - lines of equal travel time to overcome the space relative to given points, using open GIS GRASS GIS. After construc tion, the company owner of this road gives permission to the municipal and federal services and local population use for free, but a preliminary application is required. There is a payment requirement and compliance with restrictions for transportation of commercial goods. After the construction of the ESPO pipeline, people who live close to the pipeline can reach to the district centers and neighboring districts by car year-round theoretically. The materials of this study can be useful in calculating the travel time on these roads, and finding priority areas for the construction of new roads.
