This is a review of existing knowledge in indices and measuring methods for assessing the condition of cycle paths. The review is to serve as the basis for any further work that VTI may carry out in this area. The condition of the road surface is of significant importance for the comfort and accident risk of cyclists. Objective methods are needed to measure the condition of cycle paths so that the effects of operational and maintenance measures may be studied, and to set up measurable performance requirements. Presently, such methods are not used on cycle paths in Sweden. Instead, manual damage surveys and visual inspections are made; these may provide a lot of detailed information but are subjective and time consuming. Several methods for condition assessment of motor roads do exist, but they do not satisfactorily reflect the impression of cyclists regarding the road surface, and are often made using equipment that can damage the cycle path. There are also a number of hand drawn, lightweight equipments available, but they are both time and resource consuming.
