The model outperforms traditional methods by accommodating the right-skewed distribution and capturing the nonlinear effects on the trip expenses. Results reveal threshold effects: areas with higher median income level, higher POI (Point of Interest) density, and closer distance to CBD (Central Business District) yield disproportionately higher revenues.

This study addresses this gap using survey data from 1115 participants in Ghent, Belgium. Correlation analyses show alignment between perceptions and objective measures (e.g., the presence of cycling infrastructure is positively associated with older adults’ cyclability perceptions). However, some weak associations suggest that built environment perceptions may be influenced by additional factors. Multinomial logit models reveal that both perceived and objective environments influence travel mode choice, with cycling infrastructure and parking conditions playing major roles. Perceived features are more influential for some modes, objective features for others. Therefore, planning age-friendly cities requires integrating perceived and objective measures, while supporting social inclusion and sustainable, high-quality travel options.</div></div>","PeriodicalId":23277,"journal":{"name":"Transportation Research Part D-transport and Environment","volume":"148 ","pages":"Article 105024"},"PeriodicalIF":7.7,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145266731","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}

Using a desegregated model (Mobisim-Soft) to simulate daily mobilities of four French cities, this paper quantitatively evaluates several teleworking and residential relocation scenarios. Results confirm that teleworking leads to a reduction in travel distances and associated energy consumption. However, the residential relocation effect is substantial, cancelling out more than half of telework’s energy savings. While the impact of teleworking remains positive or neutral in terms of energy savings, the study suggests that more attention should be paid to complementary strategies in order to maximise its positive effects in the context of ecological transition.</div></div>","PeriodicalId":23277,"journal":{"name":"Transportation Research Part D-transport and Environment","volume":"148 ","pages":"Article 105008"},"PeriodicalIF":7.7,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145220285","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}
