On the basis of currently available methods for optimizing the road network it has been revealed that in the conditions of Yakutia the technical category of the road and construction of paved roads can not be always reliably determined. Under the conditions of Yakutia it is proposed to use the population quality of life as the main criterion while developing the design of the local road network. The necessity of the construction of paved roads, taking into account the climatic factors has been justified. And also we have proposed a system of criteria that would define the social and equitable regional development with the help of the local road network.
