Promoting public bike-sharing: A lesson from the unsuccessful Pronto system

Area of Science:

• Urban Planning
• Transportation Science
• Environmental Science

Background:

• Seattle's Pronto bike-sharing system (2014-2017) failed, necessitating an analysis of contributing factors.
• Understanding station-level trip generation and attraction is crucial for future urban mobility initiatives.
• Bike-sharing systems face challenges from urban infrastructure, weather, and public transit integration.

Purpose of the Study:

• To identify key factors influencing bike-sharing trip generation and attraction at the station level.
• To analyze the impact of land use, roadway design, elevation, bus trips, weather, and temporal dynamics.
• To provide data-driven insights for improving future bike-sharing system viability.

Main Methods:

• A generalized additive mixed model (GAMM) was employed to account for temporal autocorrelation and seasonality.
• Analysis focused on three-hour intervals of bike pickups and returns at each docking station.
• Models were estimated for total counts, user types, and location-specific trip data.

Main Results:

• Hilly terrain and rainy weather negatively impact bike-sharing usage, confirming prior assumptions.
• University District users, likely students, favor areas with higher household density and residential land use.
• Bike-sharing use correlates positively with nearby bus trip frequency, though some users shift to buses during peak/rainy periods.

Conclusions:

• Bike-sharing success is influenced by topography, weather, and proximity to public transit.
• Targeting specific user demographics and land-use patterns can enhance ridership.
• Integrated urban mobility strategies, considering transit interactions, are essential for sustainable bike-sharing.
