Researchers have introduced the Safe Bicycle Network with Bounded Detours (SBNBD) problem, aiming to upgrade rural road networks for bicycle traffic. The problem involves selecting which unsafe edges to upgrade within a budget to ensure safe paths with limited detours between specified terminals. The study proves strong NP-hardness for several graph classes and develops polynomial-time algorithms for specific graph types, demonstrating fixed-parameter tractability for certain parameters. The algorithms were evaluated on OpenStreetMap data, showing that increasing the allowed detour factor can reduce upgrade costs. AI
