Algorithm for defining bicycle infrastructures on existing city roads

The lack of space within the existing road profile has led to a lack of cycling infrastructure and the increasing mixing of cycling and motor vehicle traffic. A growing problem in modern cities is traffic due to the large number of motor vehicles. From the perspective of health, ecology and reducing traffic congestion, it is necessary to find a sustainable solution for traffic management in large cities.This paper presents an algorithm for defining bicycle paths in urban conditions. After the defined algorithm, the example of the city of Niš was taken as a check of the entire algorithm and its principle for further use. All types of traffic roads were analyzed, i.e., main, access, and collecting roads. The algorithm is divided into specific parts to include all the necessary elements for planning the bicycle path, both in the geometry design and in terms of the functionality of the bicycle path itself. Based on everything presented, the authors concluded that the algorithm includes all the necessary elements and can be applied in most cities, both here and in Europe.
