Using de-identified network mobility data, we analyze travel patterns centered around the municipality of Hope in British Columbia, Canada. Our findings reveal significant drops in travel during the peak of the floods, corresponding with major transportation infrastructure failure. The slow recovery process and dispersed residents highlight the insufficient resilience of key transportation corridors. Furthermore, the results underscore the importance of network mobility data being: 1) privacy-protected, 2) efficient and easy to examine, and 3) adaptable.","PeriodicalId":508951,"journal":{"name":"Findings","volume":"55 14","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141103338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method employs EfficientNet, a state-of-the-art neural network, to eliminate the need for additional data like street maps.

The model is pre-trained on the Cityscapes dataset and fine-tuned on images from Toronto’s 3D Massing dataset. It demonstrates strong accuracy, with an MAE of 1.21 meters, outperforming traditional methods.","PeriodicalId":508951,"journal":{"name":"Findings","volume":" 13","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140992383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that renters and residents of lower-cost housing types – multifamily and manufactured housing – are much more likely to keep their homes at unhealthy temperatures and require medical attention due to hot indoor temperatures. We also find stark disparities in heat risk for households with lower incomes, seniors, and Black, Native American, multiracial, and Hispanic households.","PeriodicalId":508951,"journal":{"name":"Findings","volume":"46 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140667199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted a content analysis of twenty-two provincial, state, and general design guides, and a topical examination of the relationship of Complete Streets elements to resilience goals. While Complete Streets topics are well integrated into guides, resilience topics are rarely present, leading to possible missed opportunities to achieve co-benefits or manage tensions. Implications from this research can begin discussions that embed safety and resilience into roadway design that also furthers multi-modal and sustainable transportation.","PeriodicalId":508951,"journal":{"name":"Findings","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140672292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A separate regression model revealed that the mobility problems explain more than half of the variance in VAS (R2=0.528). These results are promising but more research is needed to scrutinize the validity of the VAS.","PeriodicalId":508951,"journal":{"name":"Findings","volume":" 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140685482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We find women are responsible for over 70% of all child care trips. Though most child care trips are taken by automobile, women are more likely to walk kids to child care centers than men.

For public transit open-loop payments do not require agency-specific fare media, can improve boarding efficiency, reduce idling times, and remove costs associated with tickets/cards and handling cash (Iseki et al., 2007; Zamer, 2018). Using survey data collected from 21 California transit agencies we find they have positive perceptions of open-loop payments and their ability to adopt these systems. However, they affirm there are challenges including technological complexity and equipment costs. We evaluate interest in assistance programs aimed at alleviating some of the challenges transit agencies face in implementing open-loop payments.","PeriodicalId":508951,"journal":{"name":"Findings","volume":"91 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140750504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
