Speed limits of motorized vehicles have been widely used for the purpose to reduce noise and to promote road safety. Unfortunately, there has been little research on speed limits for electric bicycles (EB). In this paper, field speed data were collected from eleven segments of separated bicycle lanes in Hangzhou, China. The speeding behaviors of different types of bicycles were analyzed under different speed limits. Mixed logistic models were proposed for modeling the speeding and its influencing factors. Then, the 85th percentile speeds under different conditions were calculated as the speed limits. The stepwise regression models were proposed for modeling the relationships between the 85th percentile speeds and their influencing factors, and the speed limits for different types of bicycles were determined. It is recommended that the speed limits of purely EBs traffic were 25-30 and 30-35 km/h for the widths of bicycle lanes less than 3 m and great than 3 m, respectively. Meanwhile, the recommended speed limit for heterogeneous bicycle flow was 25 km/h. The results will help for the improvement and change of the speed limit laws and policies for bicycle traffic.

This paper was sponsored by TRB committee ANF20 Standing Committee on Bicycle Transportation.
