Abstract

Highlights: An integrated approach is proposed for Bicycle Sharing System (BSS) design by jointly considering location decisions and capacity allocation. The method combines set-covering model to assign the demand locations to stations with queuing model to measure the relevant service levels. A BSS is designed for Istanbul Technical University's Ayazağa Campus. When total capacity of a BSS is given, creating a balanced allocation of demand over the stations gives best results. The relationship between expected revenue and service fees must be analysed in design of BSS. Abstract: This study presents an integrated approach for the design of a Bicycle Sharing System (BSS) by jointly considering location decisions and capacity allocation. An important distinction of this approach is the definition of service levels, measured by the amount of unsatisfied demand both for bicycle pick-ups and returns. The method combines a set-covering model to assign location demands to stations with a queuing model to measure the related service levels. The key quality of this approach is its capacity in addressing the issues related to uncertainties in bicycle pick-up and return demand in BSS network design decisions. Results of the implementation of a BSS design for Istanbul Technical Universityâ;;s Ayazağa Campus show that our approach provides a balanced BSS network by equalizing the mean demand and return rates, which will decrease the need for relocation efforts once the system is put to use.
