Abstract
On new sections of highways in the Republic of Croatia, new facilities and installations were built for the purpose of traffic safety. Experiences in planning and designing improve specialist knowledge in certain areas of the profession. In order to solve problems, agreeing and deciding from the position of investors and other participants in construction, it is necessary to more precisely divide the competences and raise the level of assumed responsibilities of the designers. With the current legislative framework, the chief designer has assumed declarative responsibility through his professional expertise. The coordination of the project and all involved participants in the design requires an engagement that is recognized as a knowledge engineer in increasingly present expert systems that have become an essential element in the development and use of computer aids in planning and design. The paper presents examples of problem solving in the planning and design of facilities and installations in the function of traffic safety and a proposal for a framework for a new legislative solution based on continuous monitoring and the creation of knowledge bases. The new technologies of the equipment used and the new possibilities of available program support packages in designing guarantee energy efficiency, rationalization and environmental protection in the construction of transport infrastructure. The imperative of a new design direction can only be achieved with a multidisciplinary approach at the level of expertise.
