Abstract
Road cycling is a cycling discipline in which riders ride on public roads. Traffic calming
measures are made to make public roads safer for everyday usage for all its users.
However, these measures are not always yielding a safer cycling racecourse. In this
paper we present a methodology that inspects the safety of roads tailored to road bicycle
racing. The automated approach uses computer vision and geospatial analysis to give an
indicative racecourse safety score based on collected, calculated and processed multi-
modal data. The current version of our workflow uses OpenStreetMap (OSM), turn
detection and stage type / bunch sprint classification for the geospatial analysis and uses
road segmentation and an extensible object detector that is currently trained to detect road
cracks and imperfections for visual analysis. These features are used to create a mecha-
nism that penalizes dangerous elements on the route based on the remaining distance and
the generated penalties with its relative importance factors. This results in a comprehen-
sive safety score along with a detailed breakdown of the most concerning passages on the
course which can be used by race organizers and officials to help them in the iterative
process to create an engaging, yet safe course for the riders.

1 Introduction
Road cycling is an endurance sport in which athletes ride their bicycles on courses that mainly
contain public roads. The number of vehicles using these public roads is slowly increasing
