Abstract
Traffic networks within megapolises is the factor of acceleration and modernisation of the socio-economic environment.However, there exist a number of problems, which restrict the possibilities of development of a city transport medium.Particularly, road design will only begin when the living environment of urban residents is completed.In this case, formation of the road network and making decisions in respect of its modernisation are performed in accordance with the actual workload of the city network.Authors of this article state that such planning is an inconsistent process, because it cannot predict the decline of the socio-economic environment.The article expressly demonstrates that use of traditional parameters in respect of quality of design of a road network does not comply with the modern requirements to the quality of the socio-economic environment, which must be in line with the already designed road network.Authors of this article believe that it is absolutely necessary to have clear definitions of those criteria, which will be universal ones for design and management of the road network within a modern megapolis.As concerns possible solution of this problem, authors of this article propose to use ecological indicators, as well as content of toxic elements and motor vehicle emissions near the road network.
