This year’s Annual Polis Conference on “Transport innovation for sustainable cities and regions” will take place on 6 and 7 December 2017 in Brussels, organised by POLIS. The conference provides an opportunity for cities, metropolitan areas and regions to showcase their transport achievements to a large audience, and for the wider transport community to engage with representatives of local and regional authorities on innovative transport solutions. This year’s conference technical sessions will showcase many of the key topics recently explored by POLIS within its thematic working groups and projects.
