Bridges on the road network of state roads of the IB class and data required for the analysis of road safety on the bridge
Bridges are structures designed to bridge natural or artificial obstacles, such as watercourses, valleys, railways, or roads. The purpose of the bridge is to allow people and vehicles to cross a certain obstacle. This paper presents the results of research conducted in the period from 2019 to 2020 on bridges on state roads of the IB class in the Republic of Serbia. The applied methodology in collecting inventory data on bridges in order to form a basic database on bridges is presented. Also, the connection of certain data in order to conduct analyzes of bridge road safety is presented. A total of 974 bridges were identified. The paper also presents the analysis of road crashes that occurred on state roads of the IB class with a specific place "bridge", where the most common types of road crashes in the bridge zone were discovered. At the end of the paper, a critical review is given of certain elements of the bridge that may have an impact on road safety.
