Vägarbeten på cykelvägar: kunskapssammanställning och problembeskrivning

Using interviews, literature studies and accident analyses, the researchers have gathered knowledge concerning present-day procedures in connection with road works on cycle paths and how they may conceivably affect cyclists in terms of accessibility, comfort and safety. Nine out of ten cycling accidents relatable to road works occurred in urban areas, and the most common causes are: the cyclist falling off when encountering cables, hoses, pipes etc. laid across the cycle path; loose gravel, stones or dirt from the road works; high and/or unmarked edges; large potholes, ditches or other irregularities. The cyclists’ accessibility is adversely affected by all types of obstacle which road works can amount to, and above all by diversions. The cyclists’ perceived comfort is negatively affected by surface irregularities, mud, gravel and dirt which are frequently occurring in connection with road works. All in all, the studies in this project reveal a need for better knowledge and awareness as to how cyclists should be treated in connection with road works. Road authorities perceive the importance of devising working procedures which will cater to cyclists’ need of safe, passable routes even during construction processes. The big issue to them is the best way of doing this. To construction contractors the main question is rather what priority this issue has in relation to the other demands road works are subjected to. The existing guidelines appear insufficient, with their sweeping terms and woolly language, they show insufficient consideration for the circumstances and needs of cyclists. In addition, there is a lack of clear examples showing how cyclists are to be treated in practice. There is also a need for marking and fencing materials to be adapted for use on cycle paths, both for the sake of better understanding and with a view to reducing the risk of accidents.
