To determine the spatial distribution of rental stations and bikeways in a public bike system, this paper proposes a facility location and network design model. The model is developed as a multi-objective programing problem that considers four objectives (minimizing cyclist risk, maximizing cyclist comfort, minimizing adverse impacts on traffic and maximizing service coverage) and multiple constraints (monetary budget, network connectivity, station spacing, bikeway types, station number and value ranges of decision variables). The epsilon-constraint method solves the programing problem for the public bike system in Daan District, Taipei City, Taiwan. The nine non-dominated alternatives generated are all markedly better than existing locations of rental stations and bikeways. Scenario analysis results indicate that increasing the construction budget for bikeways significantly improves cyclist safety and comfort whilst increasing the adverse impact on traffic. Planners can use this model to develop public bike systems that spatially integrate rental stations and bikeway networks.

Although widely implemented, public bike systems (PBSs) are facing a conflict between system usage and sustainable financing. The relationships between PBS pricing and usage must be clarified to formulate solutions for the conflict. This research used the Taipei PBS, YouBike, as a case study. A stated preference survey was conducted on metro passengers, and a binary logit model was applied to analyze the pricing effects of PBS on passengers' choice of using PBS as their transfer mode. A latent class model was also used to identify segment-specific preferences. The empirical data show that whether commuters used PBS as a transfer mode was highly dependent on the basic fee and basic period, but not on the variable fee after the basic period; the basic fee mattered to a commuter's choice more than the basic period; irregular PBS users were more sensitive to the basic fee than regular PBS users; and regular PBS users were more sensitive to the basic period than irregular PBS users. The current results broaden the understanding of how PBS pricing affects its usage and illustrate a pricing policy analysis for YouBike that considers sustainable financing and system usage.
