In recent years, free-floating bike sharing (FFBS) has become an effective travel mode to connect the urban rail transit in the first/last mile. However, access duration, a significant factor for integrating bike and metro systems and improving the connecting efficiency, has received little attention from scholars. To fill this gap, the goal of this study is to identify the factors that affect the access duration of FFBS as a feeder mode to and from metro stations. Using operation data of FFBS in Shenzhen, China, we first explore the spatiotemporal characteristics of access duration in core area and suburb. Then, the influences of built environment, public transport services, travel attributes, temporal characteristics, and meteorological conditions on access duration for these two areas are examined using multinomial logistic models. The results indicate that: (1) access duration during the morning peaks on weekdays is shorter than that in the evening peaks and on weekends. The proportion of short access duration trips (1∼7min) among all access trips in the core area is higher than that in suburb. (2) For weekdays, more major roads increase access duration, while more branch roads would decrease it, especially in the core area. An increase in the number of subway entrances and exits significantly reduces access duration in the suburb. And the number of road intersections and congestion level in the cycling environment increase access duration, especially in the core area. (3) For weekends, the built environment has a weak impact on access duration, and higher levels of congestion in the cycling environment increase access duration, but the effect is smaller than that on weekdays. (4) Unexpectedly, the length of bicycle lanes has no significant effect on shortening access duration. Finally, elasticity analysis is carried out to identify effective policies for improving access efficiency, such as constructing branch roads in core area, improving the quality and the cycling environment of the bicycle lanes, reasonably increasing the number of subway entrances in suburb.
