Road Safety as Fundament in Road Infrastructure Planning

The road safety is a key indicator for the development of the society. May it be a key factor in the development of the road infrastructure? How will it affect the costs of road planning, construction, and maintenance? Will the “saved costs” from lowering the road accidents cover the higher cost of building and maintaining the roads? All those questions are difficult to answer; some seem even impossible. Nevertheless, it is important to analyse the problem, establish theoretical models, and formulate hypotheses. So we need to analyse the correlation between road safety, all the costs for road infrastructure, and the social effect in a theoretical manner. The paper aims to formulate the basis of the problem, and the potential solutions, analyse the needed data, and establish the theoretical models.
