Sufficient data about cyclists, their daily trips and problems is lacking. The authors used internet survey to map places perceived by cyclists as problematic. During 2 months 532 persons have responded, mapping 1 235 spots and 1 140 sections requiring repairing and improvement in reference to bicycle traffic. This dataset was completed with 1 174 respondents’ comments and 1 085 investment suggestions which facilitate interpretation of messages. Generally the most important problems were: for spots – dangerous intersection – 32%, for sections – places where vehicles drive too close bikers – 25% and bumpy surface – 22%. Problems were concentrated at the busiest city’s intersections and roads where cyclists were conflicted usually with car drivers – organization of bicycle traffic was defec tive. It is difficult to analyze such a big dataset at the level of a city – each spot has it’s unique characteristic. In order to find places of the highest concentration of necessary improvements the authors used point and line density maps. Later they analyzed in detail 6 hotspots, using information provided by respondents. Applied methodology of mapping problems in bicycle network by its users, proved to be good and effective. In a very short period we gathered big, reliable set of data, which was easy to interpret. Studying of the urban infrastructure based on the users participation will improve managing of cities in the future, not only with reference to the bicycle’s issues.
