Pavement damages on exclusive bicycle paths could affect the operation of bicycle traffic flow. The primary objective of this study is to evaluate the impacts of pavement damage at sewer well on the speed, lane change, and delay of bicycle. To achieve the research objective, filed data were collected from 9 bicycle paths with sewer wells of various altitude differences between road surface and sewer well cover in Nanjing, China. The results of t-test showed that the bicycle speeds were significantly reduced near the sewer wells only if the altitude difference was greater than or equaled to 15 mm. More than half of bicyclists chose to change lane to avoid the sewer well in each study site. The percentage of lane changes (PLC) in bicycle traffic increased as the altitude difference became larger. The study also found that even the altitude difference was near zero, the PLC was still up to 51.38% resulting in negative impacts on cycling comfort and capacity of bicycle paths. The proposed delay model achieved relatively accurate prediction for the delay in bicycle traffic caused by pavement damages. Policy suggestions regarding the pavement damage management were discussed according to the findings of this study
