We collected 10,150 home-based commuting trips data from Dhaka, Bangladesh. We then utilized three machine learning classifiers to determine the most accurate prediction model for predicting the mode of transportation chosen for commuting in Dhaka. Based on the predictive performance of the classifiers, we identified that the Random Forest (RF) algorithm performed the best. Using the RF model, this study also explored the relative importance of BE factors in predicting commute mode choice, identified nonlinear relationships between the BE factors and mode choice, and examined the interaction effects of these factors on mode selection. Our results reveal that, compared to socio-demographic factors, the BE substantially influence commuter travel behavior. The BE characteristics have a specific nonlinear threshold limit at which they can have a notable impact on lowering private car use, and private car use does not display a constant return of scale with BE. Their interaction effects illustrate the potential optimal combination of BE interventions to lower private car use for commuting. These findings hold substantial implications for urban environmental policy, emphasizing the need for transit-oriented development, travel demand management, and integrated land-use transportation planning to foster low-carbon transportation systems in cities like Dhaka. |\n\n1. Introduction  \nDespite concerted efforts to advance sustainable development, the prevalence of private car usage in urban areas continues to grow, exacerbating greenhouse gas emissions and increasing energy consumption. Consequently, this trend undermines the pursuit of sustainable mobility objectives. Developed nations engage in urban planning strategies that involve modifying the built environment of cities (e.g., compact city development, smart growth, and Transit-Oriented Development) in order to reduce private car use, thereby mitigating urban challenges and ensuring sustainable mobility (Ewing and Cervero, 2010). The built environment (BE) is widely acknowledged as a significant contextual determinant in promoting the adoption of public transportation, walking, and cycling over private car, hence offering a  \npotential remedy for reducing emission (Ashik et al., 2023; Wu et al., 2019) and enhancing physical and mental well-being (Handy et al., 2002; Panter et al., 2019).  \nIn the field of travel behavior research, it is commonly hypothesiz","cbCaimWw04pYEzbl","https://ap.wps.com/l/cbCaimWw04pYEzbl","pdf",6254701,1,16,"English","en",105,"# Introduction\n## Sustainable development and private car growth\n## Built environment as a determinant of travel mode choices\n# Data and methods\n## Study context: Dhaka, Bangladesh\n## Machine learning classifiers for prediction\n# Results and analysis\n## Best-performing model and predictive performance\n## Relative importance of built environment factors\n## Nonlinear thresholds and interaction effects\n# Implications for planning and policy\n## Transit-oriented development and integrated land-use transport","[{\"question\":\"What key patterns did the study find about built environment effects?\",\"answer\":\"Built environment factors showed nonlinear relationships with mode choice, including threshold-like limits that can reduce private car use, and interaction effects suggest optimal combinations of BE interventions.\"}]","Built environment influences commute mode choice in a global south megacity context: Insights from explainable machine learning approach - Journal of Transport Geography 116 (2024) 103828 | PDF",1785935144,40,{"code":4,"msg":31,"data":32},"ok",{"site_id":24,"language":23,"slug":33,"title":13,"keywords":34,"description":14,"schema_data":35,"social_meta":78,"head_meta":80,"extra_data":82,"updated_unix":28},"built-environment-influences-commute-mode-choice-in-a-global-south-megacity-context-insights-from-explainable-machine-learning-approach-journal-of-transport-geography-116-2024-103828","",{"@graph":36,"@context":77},[37,54,68],{"@type":38,"itemListElement":39},"BreadcrumbList",[40,44,48,51],{"item":41,"name":42,"@type":43,"position":20},"https://docshare.wps.com","Home","ListItem",{"item":45,"name":46,"@type":43,"position":47},"https://docshare.wps.com/document/","Document",2,{"item":49,"name":12,"@type":43,"position":50},"https://docshare.wps.com/document/research-report/",3,{"item":52,"name":13,"@type":43,"position":53},"https://docshare.wps.com/document/built-environment-influences-commute-mode-choice-in-a-global-south-megacity-context-insights-from-explainable-machine-learning-approach-journal-of-transport-geography-116-2024-103828/126838/",4,{"url":52,"name":13,"@type":55,"author":56,"headline":13,"publisher":58,"fileFormat":61,"inLanguage":23,"description":14,"dateModified":62,"datePublished":62,"encodingFormat":61,"isAccessibleForFree":63,"interactionStatistic":64},"DigitalDocument",{"name":9,"@type":57},"Person",{"url":41,"name":59,"@type":60},"DocShare","Organization","application/pdf","2026-08-05",true,{"@type":65,"interactionType":66,"userInteractionCount":4},"InteractionCounter",{"@type":67},"ViewAction",{"@type":69,"mainEntity":70},"FAQPage",[71],{"name":72,"@type":73,"acceptedAnswer":74},"What key patterns did the study find about built environment effects?","Question",{"text":75,"@type":76},"Built environment factors showed nonlinear relationships with mode choice, including threshold-like limits that can reduce private car use, and interaction effects suggest optimal combinations of BE interventions.","Answer","https://schema.org",{"og:url":52,"og:type":79,"og:title":13,"og:site_name":59,"og:description":14},"article",{"robots":81,"canonical":52},"index,follow",{"doc_id":7,"site_id":24},{"code":4,"msg":5,"data":84},[85,89,93,97,102,107,111,114,119,122,126],{"id":20,"doc_module":4,"doc_module_name":46,"category_name":86,"show_sort_weight":87,"slug":88},"Story & Novel",90,"story-novel",{"id":47,"doc_module":4,"doc_module_name":46,"category_name":90,"show_sort_weight":91,"slug":92},"Literature",80,"literature",{"id":53,"doc_module":4,"doc_module_name":46,"category_name":94,"show_sort_weight":95,"slug":96},"Exam",70,"exam",{"id":98,"doc_module":4,"doc_module_name":46,"category_name":99,"show_sort_weight":100,"slug":101},5,"Comic",60,"comic",{"id":103,"doc_module":4,"doc_module_name":46,"category_name":104,"show_sort_weight":105,"slug":106},6,"Technology",50,"technology",{"id":108,"doc_module":4,"doc_module_name":46,"category_name":109,"show_sort_weight":29,"slug":110},7,"Healthcare","healthcare",{"id":11,"doc_module":4,"doc_module_name":46,"category_name":12,"show_sort_weight":112,"slug":113},30,"research-report",{"id":115,"doc_module":4,"doc_module_name":46,"category_name":116,"show_sort_weight":117,"slug":118},9,"Religion & Spirituality",20,"religion-spirituality",{"id":117,"doc_module":4,"doc_module_name":46,"category_name":120,"show_sort_weight":117,"slug":121},"World Cup","world-cup",{"id":123,"doc_module":4,"doc_module_name":46,"category_name":124,"show_sort_weight":123,"slug":125},10,"Lifestyle","lifestyle",{"id":127,"doc_module":4,"doc_module_name":46,"category_name":128,"show_sort_weight":98,"slug":129},19,"General","general"]
