Measures for elderly people Research for an ageing Society Face-to-face interviews If I was a mayor, I would like to… …enhance traffic signals and refuges/pedestrian crossings, …appoint city-service and police more often, …sensitize fellow citizens, …care for road maintenance, …barrier-free sidewalks, …build more and cheaper parking-lots, …establish more traffic calming.
