Sustainable transport, as one of the areas on which sustainable development should be founded, depends more and more on introduction of electric vehicles in daily traffic. This paper describes part of the results of wider research related to the analysis of all sustainable transport indicators. Since introduction of electric vehicles is supposed to be done stage by stage in the actual transport, deep understanding of its main parameters/indicators is a prerequisite for reliable analysis. The paper identifies traffic and vehicle structure parameters and rang them in hierarchic order. This structure can serve as substructure in more complex structure of all transport parameters in wider researches.

Within the transport process there is continuous interaction between the three main factors: behaviour of road users, infrastructure conditions and characteristics and vehicles. As a matter of fact, the aforementioned factors are key sources of causes for traffic accidents.
The purpose of the present article is to propose such a road traffic organization that would reduce congestions, minimize the number of road accidents and the risk to health and life and would enhance safety. In this context certain characteristics of a specific road section in Bulgaria will be examined. Furthermore measures for improving traffic conditions and safety will be defined.

This article renders the results from researching the traffic intensity of the vehicles and the pedestrians through the crossroad in the town of Smolian, direction Kosta Avramikov str – Rodopi str and vice versa.
