Bikealyze: Analysis of Overtaking Maneuvers Between Motor Vehicles and Bicycles
Bikealyze is a specialized service for recording and analyzing interactions between cyclists and other road users in public road space. Currently, the service focuses on analyzing overtaking maneuvers between motor vehicles and bicycles.
The analysis of overtaking maneuvers between motor vehicles and bicycles provides important insights into objective and subjective safety in bicycle traffic—an aspect that is increasingly becoming the focus of municipal traffic planning. The method for analyzing overtaking maneuvers between motor vehicles and bicycles has already been tested in practice in the cross-state research project “RADBEST – Radverkehrsführung bei beengten Straßenverhältnissen” (RADBEST – Cycling in confined road conditions) led by Salzburg Research Forschungsgesellschaft and is being continuously developed as part of Bikealyze. The central question here is whether and in which situations the legally prescribed minimum distance when overtaking cyclists is observed, and which bicycle traffic routing systems promote safe overtaking.
Data is collected using the Holoscene Bike, a research bicycle equipped with comprehensive sensor technology, including LiDAR, cameras, GNSS, and IMUs. The LiDAR technology enables three-dimensional representation of the environment. Algorithms automatically add motor vehicles (cars), their positions, and their dimensions in the collected data. Safety-related parameters for the entire overtaking process can then be derived from the collected data, such as the distance and speed differences between motor vehicles and bicycles in different phases of the process. These parameters allow for an objective evaluation of the safety of cyclists on the examined route.
The results include a statistical evaluation of the individual measurements, as well as map-based visualizations of the results. The findings are clearly presented in graphic form and provided as a PDF presentation. Optionally, they can be provided in the form of a finalized report.
Your benefit
Through objectively measuring and analyzing overtaking maneuvers between motor vehicles and bicycles, you will recieve:
- Objective and well-founded data on the safety of cyclists on specific road sections.
- Support for evidence-based planning and evaluation of cycling infrastructure measures.
- Decision-making criteria for transport planners, cities, and municipalities to enable them to respond specifically to weak points.
- Contribution to increasing perceived safety and thus promoting cycling.
