Dynamic Homogeneity and Functional Dependence on the Number of Traffic Accidents, the Role in Urban Planning

This paper presents certain research of some roads in the Republic of Macedonia, with the purpose to express the functional dependence of the dynamic homogeneity on the number of road accidents in the urban area. The paper presents a relationship between the medium quadrat deviation and the medium velocity in a free traffic flow. The dynamic homogeneity is obtained as on the basis of the construction of the velocity in a free traffic flow, on which the adequate diagrams were construed, depending on the designed geometric elements on the alignment of the road in the plan and the profile. Furthermore, pursuant to the parameter of the dynamic homogeneity it is possible to numerically evaluate the success of the alignment solution and a numeric comparison of the variants in the pre-design stage, or in the stage of an preliminary design. This research can serve as an analysis of the alignment of the road as referring to the newly designed and the already constructed roads. (C) 2015 The Authors. Published by Elsevier Ltd.
