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.

One of the most important characteristics of transport systems is the reliability of their performance. Significant global efforts are being made in this direction, both by the relevant government structures, and individual transport operators. These efforts are justified because improvements in the sphere of safety and reliability entail considerable benefits to transport users (reducing the waiting time of passengers, improving the quality of service in general, increasing supply chains reliability level, etc.) and for operators offering such a service (higher level of competitiveness, more revenues, etc.). This article examines the nature, existing problems and opportunities for improvement of approaches and methods of analysis, evaluation and management of exploitation reliability (and respectively transport service quality) of transport systems.

Recently, the issue of safety has not been whether or not Safety Management Systems are necessary to secure a high level of operational safety in railways but if they could eventually be improved. The answer is yes and that improvement can be done on the basis of well known (and adapted to the problems of safety) scientific approaches and methods. In other words, safety understanding will be developed into a new stage – Modern Safety Management System. The present paper discusses the possibilities for the introduction of some scholarly methods into safety management in railways.
