With more than 1.35 million fatalities worldwide each year, road crashes are among the world’s most significant public health and injury prevention problems. In the last decade, with the new technological breakthroughs, a significant effort has been devoted to improving different safety systems related to infrastructure and vehicles. Road marking and road signs represent main road elements whose main task is to provide timely and necessary information to the drivers related to the upcoming situation. In other words, they warn and inform drivers about the conditions and construction characteristics of the road, guide road users through the traffic network and regulate traffic in a safe way. Therefore, continuous monitoring and testing of their quality is of great importance for road safety in general. The a im of this paper is to present Croatian experience regarding the quality testing of road markings and signs in last decade. Overall, the analysis confirmed that systematic control of road markings and signs will positively affect their quality and optimize maintenance activities

Safety of all road users on the roads is one of the fundamental social objectives. Measures for improvement or remediation of dangerous sites (black spots) in Croatia are carried out in several phases, from planning the envisaged measures, valuation measures, the implementation of measures to observation and assessment derived measures. Certain dangerous places are repaired only by changing traffic signalization and those sites and measures are described in this paper. In last eight years on the roads in Croatia, 215 dangerous places were repaired and partial restoration was carried on the 46 dangerous places. The success of provided measures, expressed through an analysis of the number and consequences of accidents on dangerous places for three years before and three years after restoration, shows the drastic reduction in traffic accidents on this places. The conclusions and solutions of these measures are presented in this paper.
