abstract = {This study explores the effectiveness of mobile application interventions in promoting walking among diverse demographic groups using Difference-in-Differences (DiD) analysis. It examines how strategies like monetary incentives, health data, and visual feedback influence behaviours across demographic factors like age, gender, and income, revealing the most effective for specific groups. Young participants who received all types of interventions demonstrated a significant increase in step counts, with an estimated increase of 182 %, reflecting their receptiveness to personalised engagement and reward-based strategies. In contrast, low-income participants experienced a significant decrease in step counts, with a reduction of 54 %, highlighting the socio-economic barriers hindering intervention effectiveness. These findings underscore the importance of tailoring intervention designs to meet different demographic groups’ specific need and ensure equitable outcomes. This study offers valuable insights for policymakers, public health officials, and practitioners aiming to design more effective and inclusive strategies to promote physical activity and improve urban sustainability.},

abstract = {A key challenge for transport managers and planners in sustainable development is evaluating transit facilities' performance. While Multi-Criteria Decision-Making (MCDM) tools are often used, they can be influenced by experts' subjective biases. This study applies MCDM to assess Mass Rapid Transit (MRT) stations in Jakarta, Indonesia, focusing on Transit-Oriented Development (TOD). The primary goal is to compare stakeholder perspectives and MCDM methods, complemented by a sensitivity analysis and validation with real-world smart card data. The findings reveal significant differences in criteria weighting between Indonesian and non-Indonesian experts, and between academic and non-academic experts, especially in transit connectivity and land use diversity. The study also shows variations in station rankings across different MCDM methods. Sensitivity analysis identifies transit connectivity as the most critical criterion. Simple Additive Weighting (SAW) with linear normalisation aligns well with actual usage data and shows robustness in sensitivity analysis, making it the most reliable method for TOD evaluation. The study highlights the need for continuous TOD performance monitoring and the regular collection of real-world data on ridership and TOD indicators.},
