TL;DR: In this paper, a new generation of bike-sharing services without docking stations is introduced, which is currently revolutionizing the traditional bike sharing market as it dramatically expands around the world.

TL;DR: This study aims at understanding the usage of new dockless bike-sharing services through the lens of Singapore's prevalent service, and adopted spatial autoregressive models to analyze the spatiotemporal patterns of bike usage during the study period.

TL;DR: In this article, the authors examined salutogenic environment effects of urban green upon walking behavior and how such effects are mediated by built environment configuration and street-level physical accessibility, and demonstrated the necessity for targeted intervention strategies in activity-friendly planning via greening and optimized physical design of urban built environments.

TL;DR: This research proposes an analytical framework to unravel the landscape and pulses of cycling activities from a dockless bike-sharing system in Singapore and demonstrates the effectiveness of eigendecomposition for uncovering the system dynamics.

TL;DR: This paper proposes to use artificial immune systems (AIS) as a technique for incorporating external interventions and generating alternatives in urban simulation and applied an AIS-based CA model to the simulation of urban agglomeration development in the Pearl River Delta in southern China.
