This study addresses safety perceptions while evacuating, and specifically asks what personal, built environment, and evacuation factors contribute to feelings of safety during a wildfire evacuation? Using post-disaster survey data from the 2018 Camp Fire evacuation, we build an ordered logit model which estimates perceived safety as the outcome, accounting for several factors including evacuee proximity to the oncoming wildfire, socio-demographics, evacuation decision-making, and traffic conditions. The results show that later departure timing, shorter travel time, and pre-planning for evacuation routes and destinations to be associated with increased safety while on the evacuation route. These findings have important implications for emergency planning for wildfires, including fast-moving wildfires as well as evacuation modeling for these events.

Therefore, there is a pressing need for an in-depth analysis of the possible risk factors to improve the safety of the riders and the surroundings. Adopting a systematic approach, we designed five experiments focusing on self-stability, handling, acceleration, braking, and obstacle interaction, considering common causes of accidents and representing different riding scenarios. In this study, we experimentally investigated the dynamic performance and safety considerations of small-wheel (<20 in.), lightweight (<20 kg), and compact (800–900 m) micro-mobility devices, encompassing Power Assisted Bicycles (PABs) and Personal Mobility Devices (PMDs). A total of eight devices, including four PABs (e-bikes) and PMDs (e-scooters) with different wheel sizes, braking types, operating voltages, motor ratings, and two mechanical bicycles, were selected for the study. Results highlight that compact small-wheel PABs and PMDs exhibit reduced stability compared to larger-wheeled counterparts, indicating that their design is not well optimized. The study also highlighted risks associated with hand signals and obstacle interactions for these devices. Moreover, the study also investigates the effect of higher voltage batteries together with higher motor ratings on safety. The study recommends key measures, such as optimizing frame design, adopting a minimum wheel size of 14 in., regulating voltage and motor power, and introducing features like turning lights, mirrors, and front suspension to enhance safety. These insights contribute valuable recommendations for designing and regulating small-wheel micro-mobility devices to mitigate accidents and promote safer transportation practices.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"31 ","pages":"Article 101376"},"PeriodicalIF":3.9,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143643084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While Mid-block Pedestrian Signals (MPS) was found to improve safety compared to the other traffic control systems as drivers were found to comfortably reduce speeds, Pedestrian Hybrid Beacons (PHB) and Rectangular Rapid Flashing Beacons (RRFB) raise safety concerns due to the potential of sudden braking. Despite RRFB’s site having similar average braking distance compared to the site with MPS, RRFB’s was found to have a higher deceleration near the stop line suggesting abrupt braking and thus creating unsafe conditions. In addition to the video analytics that included vehicle dynamics, the pedestrian and road characteristics and their interactions were also analyzed by estimating a mixed logit model with heterogeneity in the means of random parameters. The study found that factors such as average vehicle speed and maximum deceleration, hourly pedestrian count, pedestrian signal activation, vehicles in lanes near the curb, and night conditions played a role in pedestrian safety at the mid-block crossings. The findings also indicate the need for clear visibility and comprehensive understanding of signals, particularly PHB and RRFB, to enhance safety.

This area has received limited research attention. This study aims to develop a travel time prediction model for a 13 km corridor, specifically a two-lane, two-way, undivided rural highway section of the East-West Highway. By analyzing 72-hour datasets on vehicle travel time obtained from traffic volume counts, the study evaluates the performance of machine learning regression techniques, incorporating factors such as through traffic volume, opposing traffic volume, and the percentage of heavy vehicles in through traffic. The regression analysis reveals a moderate correlation between travel time changes and variations in the independent variables. Furthermore, statistical error tests demonstrate that the random forest method outperforms other approaches in predicting travel time.

Ensuring that public transit services meet their needs could contribute to their independent mobility and long-term health. Accessibility, the ease of reaching destinations by a certain mode, is a measure that can be used to indicate how well the land use and transport systems allow people to reach their desired destinations. This paper explores how perceived and objective levels of accessibility influence older adults’ frequency of public transit use in a Canadian context. Based on a survey collected in six Canadian regions (N = 2,452), we use respondents’ stated reasonable travel time by public transit to generate a personal-time-based cumulative accessibility measure. We then develop a weighted binary logistic regression model to understand the impacts of the personal-time-based accessibility measure, perceived accessibility, and other personal characteristics on older adults’ frequency of public transit use. The results indicate that both perceived and personal-time-based accessibility have a strong and positive impact on frequent public transit use. Older women were found to be more frequent public transit users, whereas older adults who have access to a private vehicle use public transit significantly less. Findings from this research support the utilization of accessibility by public transit as a tool to better assess and plan for the transport needs of older adults. The results can be relevant for transport planners and policy makers interested in improving the well-being and independence of older adults through increasing their use of public transit.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"31 ","pages":"Article 101381"},"PeriodicalIF":3.9,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143611562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we used a stated preference survey dataset to understand (i) how the intended frequency of online grocery shopping varies across people, (ii) how their other day-to-day lifestyle activities influence online grocery shopping frequency, and (iii) what role does their residential built environment play in online grocery shopping frequency. We performed Latent Class Analysis to classify people into different classes based on heterogeneity in their lifestyle, which we defined as a combination of their social proclivity, liking for outdoor activities, technology friendliness, and pro-environment choices. We then modeled the intended frequency of online grocery shopping across the latent classes controlling for residential built environment characteristics, life stage, and socioeconomic characteristics of class members. Our results indicate that lifestyle characteristics, life stage, and residential built environment strongly influence online grocery shopping frequency. In fact, life stage significantly influences online grocery shopping frequency, irrespective of lifestyle characteristics. Further, having mixed land use at the residential location can motivate people to do in-person grocery shopping using active modes even when their lifestyle characteristics are not necessarily aligned with eco-friendly living.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"31 ","pages":"Article 101382"},"PeriodicalIF":3.9,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143611561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
