ALGORITHM FOR POSITIONING CYCLING INFRASTRUCTURE WITHIN THE EXISTING PROFILE OF AN URBAN ROADWAY

<p><em>This paper presents an algorithm for positioning cycling infrastructure within the existing cross-section of a roadway. The analysis focuses on roadways in urban areas, specifically city streets. The input data consists of the geometric elements of the situational plan, longitudinal profile, and cross-sections. The algorithm first classifies them based on the street category criteria. Various analyses are conducted depending on whether the street in question falls into the category of main, collector, or local streets. In this phase, the algorithm analyzes the elements of the cross-section of the urban roadway. Upon completing this step, a preliminary solution for the positioning of the cycling infrastructure is formed, followed by a detailed analysis of all geometric elements of the street, considering the conditions for bicycle traffic in an urban area. Additionally, an analysis of the horizontal and vertical geometry of the examined street is performed. If all criteria are met, the preliminary solution is adopted as the final one.</em></p>
