Quantifying Cycling Infrastructure Investment Needs Across Europe Using OpenStreetMap Data
摘要
Using OpenStreetMap data, we approximated the scale of investments needed to make cycling a safe mobility option for the residents of EU major cities. We extracted data about existing cycle tracks, cycle lanes, and shared cycle and pedestrian tracks, within the administrative borders of 423 Trans-European Transport Network (TEN-T) urban nodes (as proposed by the European Commission in 2021). As of 2022, the infrastructure amounted to 61,862 km. Afterwards, we used a simplified version of the Sustainable Safety approach to evaluate for each of the cities whether the amount of infrastructure is sufficient. The public road network was divided into two categories: main roads (where segregated cycling infrastructure is necessary) and local roads (where, because of low volume and speed of motorised traffic, cyclists can safely share the carriageway with cars). By comparing the extent of the (selected) cycling infrastructure with the main road network we arrived at the investment needs, amounting to 97,000 km across the analysed cities. On average, current cycle infrastructure covers approximately 40% of the needs, but the percentage varies significantly between different countries – from less than 10% in Malta, Greece, Portugal and Cyprus to more than 80% in Netherlands and Finland.
