This study analyses data from 48,839 respondents across twelve diverse Indian cities, using a mixed-methods approach, including machine learning (ML) and Double Machine Learning (DML) to examine pre- and post-pandemic mode choice dynamics at aggregate and city-specific levels. The ML analysis identified fundamental life circumstances as the primary predictors of mode choice. The DML analysis revealed that while public transport (PT) demonstrated significant resilience, powerful behavioural inertia persists, and specific service failures causally deter PT adoption. Pre-pandemic private vehicle use is causally linked to a lower likelihood of shifting to PT. Furthermore, safety and comfort issues, such as station cleanliness and staff professionalism, are causally linked to negative passenger perceptions. The study highlights significant city-specific variations and informs targeted, actionable, evidence-based policy recommendations for developing more resilient and environmentally sustainable urban transport systems.</div></div>","PeriodicalId":23277,"journal":{"name":"Transportation Research Part D-transport and Environment","volume":"147 ","pages":"Article 104968"},"PeriodicalIF":7.7,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144895185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study incorporates equity into the cost-effectiveness evaluation of TIMOD services, analyzing two suburban areas in the Seattle metropolitan region where a TIMOD service is implemented. Using distributional cost-effectiveness analysis (DCEA), we assess the comparative costs of TIMOD, fixed-route transit, and drive-alone across different income groups and built environments. The study shows that although TIMOD services offer equity benefits for lower-income travelers, they are more equitable in high-density, low-income suburbs. In contrast, their cost-effectiveness is more limited in affluent, low-density areas. These insights highlight the importance of context-specific planning for TIMOD interventions and employ tools such as DCEA for transit agencies to prioritize the deployment of such services in areas where they can maximize social welfare and reduce transportation inequities.</div></div>","PeriodicalId":23277,"journal":{"name":"Transportation Research Part D-transport and Environment","volume":"147 ","pages":"Article 104959"},"PeriodicalIF":7.7,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144887573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results show strong positive correlations between produced and attracted commuting. Distance to business center is the most important predictor. As this distance grows, both produced and attracted commuting distances increase. Its association with attracted commuting distance differs from that in developed countries.

Using the LSEG Environmental, Social and Governance database (previously known as Refinitiv), we analyze a sample of 2,932 organizations employing over 86 million people across 73 countries to identity predictors of (a) workplace travel policies, and (b) commuting emission reductions. Drawing on political and organizational science literatures, we examine the roles of employee involvement and trust in reducing travel emissions. Sector characteristics strongly influence policy adoption—professional services firms are six times more likely than manufacturing firms to implement transportation policies (OR = 5.98, p < 0.001). While these policies significantly correlate with emissions reductions, the effect size is modest (Cohen’s d = 0.225, R2 = 0.0765).Notably, trust in employers emerges as a significant predictor of emissions reductions (β = -0.122, p < 0.05), while traditional employee involvement structures show limited effectiveness.
