Measurement of Integration of Shared Bicycle Stations to Rail System in Providing Sustainable Mobility; Examining Examples from Turkey

In recent years, the paradigm shift towards sustainable mobility in transportation planning has led to an acceleration in scientific studies aimed at improving the performance of sustainable urban transport modes. The aim is to increase sustainability performance by facilitating the transition between sustainable modes within sustainable mobility systems. The concept of intermodality is key to overcoming the origin and destination transport problem (the first and last mile problem) in public transport. Shared bicycle systems, which support rail public transport, are a tool that can increase the performance of sustainable urban mobility as an intermodal travel model, overcoming the first and last mile problem. Well-planned shared bicycle systems that are well-integrated with rail systems increase the success of rail systems in cities and enhance their sustainability impact. This paper aims to present literature on the integration of shared bicycle stations into rail systems, evaluate the level of integration of urban rail systems with shared bicycle systems in Turkey and provide recommendations for transport policies to increase the sustainability impact of rail systems. Additionally, measuring the spatial accessibility of shared bicycle stations within a pedestrian access distance of rail system stations using the isochron mapping method provides a suggestion that can be used elsewhere in the world to measure the level of intermodality between rail systems and shared bicycle systems.
