BATS Impact Report: Results and Lessons from Year-Round Active Mobility Pilots

Jacek Oskarbski, Konrad Biszko, Daniel Kaszubowski · 2026

Summary

The BATS Impact Report (Deliverable D2.2), prepared by Gdańsk University of Technology, examines the observed outcomes, implementation experiences and operational lessons from Year-Round Active Mobility (YRAM) experiments in seven Baltic Sea Region pilot areas: Hamburg-Altona (Germany), Gdynia (Poland), Umeå (Sweden), Porvoo (Finland), Kalundborg (Denmark), Klaipėda (Lithuania) and Kiili/Harju County (Estonia). The report evaluates interventions across four thematic areas: infrastructure, traffic management, winter maintenance and citizen activation. Practical examples include physically protected cycling infrastructure and illuminated underpasses in Hamburg-Altona; weather-adaptive traffic signal control and school travel campaigns in Gdynia; citizen-based winter maintenance monitoring, projected markings and winter e-bike initiatives in Umeå; coordinated winter maintenance and user feedback systems in Porvoo; cycling route visibility improvements and commuter engagement in Kalundborg; projected guidance for shared bus-cycle environments in Klaipėda; and school-based winter cycling promotion and winter maintenance bottleneck mapping in Kiili and Harju County. For each pilot area, the report describes intervention objectives, monitoring methods, observed results, implementation barriers, enabling factors and recommendations for replication. The cross-city synthesis highlights the importance of reliable winter maintenance, route visibility, understandable information about travel conditions and citizen activation measures linked to practical support. A central finding is that year-round active mobility depends on the combined performance of infrastructure, maintenance, traffic management and user-oriented services. Communication campaigns alone cannot compensate for unusable or unsafe routes, while technical solutions require appropriate maintenance arrangements, institutional coordination and monitoring. Because the experiments differed substantially in scale, baseline conditions, monitoring methods and data availability, the report does not provide a statistically comparable ranking of intervention effectiveness. Instead, it offers operational evidence and transferable implementation lessons to help municipalities select, adapt and evaluate interventions suited to their local conditions.
