The POLIS Annual Conference is Europe’s leading sustainable urban mobility event, providing an opportunity for cities and regions to showcase their transport achievements, including recent safety developments, to a large audience of mobility experts, practitioners, and decision-makers from both the public and private sector. Urban Road Safety is a key conference priority.
