The rapid growth of urbanization and the increasing use of motor vehicles have intensified transportation challenges, such as congestion and air pollution. In light of this, bicycle-sharing systems have emerged as a sustainable and cost-effective solution. This study presents the design of a bicycle-sharing system for the University of Bojnord, covering an area of approximately 150 hectares with more than 5,000 students. A mixed-integer linear programming model was developed to determine the optimal number and locations of bicycle stations as well as the required bicycles while minimizing total system costs, including installation, purchasing, and maintenance. The model was solved and analyzed using GAMS software. Sensitivity analysis was conducted to evaluate the effects of key parameters, and the most frequent travel routes were identified to enhance system efficiency. The results indicated that implementing the proposed system can significantly improve transportation quality and promote sustainable mobility within the campus. However, successful implementation requires the development of supporting infrastructure, including smart stations and secure parking areas. The proposed framework can also serve as a reference for designing similar systems in other universities and urban areas.
