Winter slip-and-fall incidents cost about €570m a year — ten times municipal sidewalk spending

A joint study of Finnish cities finds slip-and-fall incidents tied to inadequate winter maintenance cost about €570 million a year — more than ten times the current annual sidewalk winter-maintenance bill of roughly €47–54 million, the City of Tampere said. The gap is stark.

Led by WSP Finland and funded by the Finnish Transport and Communications Agency (Traficom), the research combined municipal cost data and GIS-based network analysis to compare upkeep expenses with the societal costs of falls and changes in walking.

It shows sidewalk maintenance costs vary with land-use density and how services are organised. Simply spending more money does not automatically raise maintenance quality or reduce falls.

Researchers recommend improving the quality and targeting of winter measures — especially on everyday errand routes — improving forecasting of maintenance needs and adopting route-level upkeep strategies.

The study finds about twenty particularly icy days on average each winter. Older people and mobility-aid users cut back walking the most, so a high baseline level of winter maintenance is essential for year-round mobility and for other measures to succeed.
