Spatial information was incorporated in the models to capture spatial autocorrelation. The results revealed the importance of spatial information in predicting pedestrian injury severity. Other important predictors of pedestrian injury severity include aggressive driving, driver’s conditions (e.g., inattentive, slowly stopping, driving properly, failing to yield right of way), pedestrian conditions (e.g., normal, inattentive) and dark lighting conditions.","PeriodicalId":73025,"journal":{"name":"Findings (Sydney (N.S.W.)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134901217","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}

Longer daylight hours and more nighttime walking do not appear to be the reasons for some states’ much higher pedestrian fatality rates.","PeriodicalId":73025,"journal":{"name":"Findings (Sydney (N.S.W.)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134953475","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 reverse interpretation of the resilience triangle is proposed, where smaller triangle areas indicate less resilient populations continuing to travel despite disruptions, while larger demand losses indicate greater adaptability. Using Google Popular Times data, the study measures activity levels in neighborhoods, focusing on essential and non-essential trips. Vulnerable groups with lower incomes show limited adaptability, resulting in a smaller reduction in commercial activities compared to affluent neighborhoods. The study emphasizes the significance of considering demand adaptability and socioeconomic factors in assessing resilience.","PeriodicalId":73025,"journal":{"name":"Findings (Sydney (N.S.W.)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136376325","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 sought, through 16 qualitative interviews with users, to understand whether CSA use in Montreal, Canada was accompanied by more ecological, non-motorized travel behavior. We find that urban users are typically able to subscribe to a nearby drop-off point and that many of them use non-motorized modes to access their weekly baskets. However, because of the weight of large produce baskets and the set time periods for collection, basket pick-ups by new Covid-19 era users are often part of car-based trip chains.","PeriodicalId":73025,"journal":{"name":"Findings (Sydney (N.S.W.)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135367117","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}

Participants identified barriers to fleet electrification including lack of knowledge on fleet electrification, high utility demand charges, lack of charging infrastructure, delays in grid infrastructure upgrades and high up-front costs. To overcome these challenges, panelists emphasized partnering with OEMs and utilities, and having flexible charging infrastructure with software support tools. Finally, participants identified opportunities for integrating with electricity markets on peak demand management, time-of-use charging, participation in wholesale markets, and various vehicle-to-grid solutions. Based on these findings, we propose specific steps that various stakeholders like fleet operators, utilities and regulatory authorities could take.","PeriodicalId":73025,"journal":{"name":"Findings (Sydney (N.S.W.)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136252937","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}

Furthermore, we modelled these clusters in terms of commute times to work by mode. The findings suggest that morning electricity consumption differs significantly among clusters and that it is caused primarily by long duration public transport trips.","PeriodicalId":73025,"journal":{"name":"Findings (Sydney (N.S.W.)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134910692","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}

Thus, the study provides a new perspective on this temporary policy and underscores the value of experimentation as a governance tool for the transition to sustainable mobility. This value goes beyond the direct traffic-related impact: The contribution of the 9-Euro-Ticket to a new stable configuration, the ‘Germany ticket’, is identified as the main output.","PeriodicalId":73025,"journal":{"name":"Findings (Sydney (N.S.W.)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45233216","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}
