In practice, most research has focused on simple measures of proximity that, while easy to understand, fail to capture the potential for interaction using the transit network. Through the example of the King Street Transit Priority Corridor project, this research examines how transit accessibility, and changes in access over time that result from streetcar service upgrades, are capitalized into condominium prices in Toronto, Canada. Methodological and applied contributions include calculating streetcar travel time differences using disaggregate vehicle tracking data, calculating transit accessibility using a gravity-based measure with a calibrated impedance function, accounting for variations in accessibility over the course of a day as well as changes over time, incorporating measures of access to local amenities, transforming 2D transaction information to a 3D format, and specifying 4D spatio-temporal weights. Longitudinal model results indicate that transit accessibility is a significant determinant of condominium prices. While the service upgrades did not dramatically increase accessibility levels and the implicit value of accessibility did not change over time, panel model results find that condominium property prices appreciated by about 2.7% more on average in the King Street streetcar corridor relative to the Sheppard subway control after the introduction of the priority corridor pilot. This result suggests the corridor on the whole may have became more attractive relative to Sheppard in the pilot phase.</p></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":null,"pages":null},"PeriodicalIF":6.3,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142232234","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}

However, the increased user flexibility introduces challenges from an operator perspective. To make services profitable, the total idle time of vehicles needs to be minimised and available vehicles should be located where demand exists. To increase profitability, it is important to carefully choose the operational area based on the expected idle time that different locations may offer, and only strategically expand into areas where the sustainability of the service can be maintained. In this paper, we present a hazard-based duration model for the idle times of a car sharing vehicle service. It is argued that modelling of idle time as opposed to bookings, which is the common approach, allows to circumvent the problem of latent demand and thereby presents itself as a simpler modelling strategy. In the paper, the model is applied to the city of Copenhagen, where we study the operational performance on the basis of 327,610 electric free-floating car trips in the period 2017-2018. We study the performance over 92 existing zones and predict the expected performance for an additional 28 zones by considering geographical and socio-economic drivers of demand. This enables the prediction of which areas to include as part of an expansion of the operational area, and thus serves the purpose of a strategic planning tool for growing such services. It is found that the additional zones differ substantially in their performance, which is a consequence of zones being more or less aligned with the local FFCS drivers of demand. This leads to a prioritisation of zones for further expansion based on performance, where the idle time of the best performing zones is seen to be as much as one hour less than the worst performing zones.</p></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":null,"pages":null},"PeriodicalIF":6.3,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0965856424002891/pdfft?md5=d84f1695468856ea8ea1c364373789a1&pid=1-s2.0-S0965856424002891-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142169165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Real-time forecasting of travel demand during wildfire evacuations is crucial for emergency managers and transportation planners to make timely and better-informed decisions. However, few studies focus on accurate travel demand forecasting in large-scale emergency evacuations. To tackle this research gap, the study develops a new methodological framework for modeling highly granular spatiotemporal trip generation in wildfire evacuations by using (a) large-scale GPS data generated by mobile devices and (b) state-of-the-art AI technologies. Based on the travel demand inferred from the GPS data, we develop a new deep learning model, i.e., Situational-Aware Multi-Graph Convolutional Recurrent Network (SA-MGCRN), along with a model updating scheme to achieve real-time forecasting of travel demand during wildfire evacuations. The proposed methodological framework is tested using a real-world case study: the 2019 Kincade Fire in Sonoma County, CA. The results show that SA-MGCRN significantly outperforms all the selected state-of-the-art benchmarks in terms of prediction performance. Our finding suggests that the most important model components of SA-MGCRN are weekend indicator, population change, evacuation order/warning information, and proximity to fire, which are consistent with behavioral theories and empirical findings. SA-MGCRN can be directly used in future wildfire events to assist real-time decision-making and emergency management.</p></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":null,"pages":null},"PeriodicalIF":6.3,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0965856424002908/pdfft?md5=8588f77b026f7bec595fc78f37e0289f&pid=1-s2.0-S0965856424002908-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142162493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our estimates indicate a limited incentive effect of purchase subsidy policies, signaling the need for a phased withdrawal of such incentives while exploring cost-effective alternatives. Furthermore, our study highlights the intricate relationship between policy diversity and overall effectiveness, emphasizing the potential crowding-out effects observed when multiple policies are concurrently implemented in cities. The effect of policy mixes is different among cities with different sales level, income level and population density. The effect of policy mixes is better in cities with a higher sales level, an upper middle-income level, and a medium population density.

We asked ourselves two main questions: (i) will people continue riding transit after COVID-19? and (ii) what are riders’ reasons behind increasing, maintaining, or decreasing public transport use? Using a two-wave survey conducted in 2020 and 2021, we assessed the motives behind future public transport use in two Canadian cities (Toronto and Vancouver). We used quantitative and qualitative methods, particularly latent class cluster analysis (LCCA), text mining, and qualitative content analysis. We identified six transit riders’ profiles, ranging from those experiencing transport poverty who rely on public transport to those more resourced users who will ride less since they can choose alternatives such as remote work, private modes, or active travel. We discuss the policy and practice implications of these results, focusing on what public transport decision-makers should prioritize to benefit disadvantaged groups and recover ridership.</p></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":null,"pages":null},"PeriodicalIF":6.3,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0965856424002878/pdfft?md5=f1de3a157f76d732564d84d0620899cd&pid=1-s2.0-S0965856424002878-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142158457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prior studies focused on the departure times of fixed and flex-time workers without categorising them by work-from-home options (non-teleworkers, hybrid workers, and passive teleworkers). Nevertheless, the factors influencing the departure time may vary among worker categories. Furthermore, the data source of prior studies was the Household Travel Survey, collected pre-COVID-19. However, the pandemic has substantially altered workers’ perspectives on flexible work arrangements. Therefore, understanding the departure time of various workers in the post-COVID-19 era is crucial to managing peak-hour travel demand effectively. Hence, this study aims 1) to investigate the departure time distribution of various worker categories, 2) to examine the factors influencing it, and 3) to propose a suitable policy to optimise the peak-hour travel demand.</p><p>Survival analysis was used to analyse the continuous nature of departure time using data collected from 10 June to 20 July 2023 in Greater Kuala Lumpur, Malaysia.

Fixed-time workers significantly consider multiple factors when determining their departure time, surpassing the considerations of flex-time workers. The departure time of fixed-time workers is significantly influenced by gender, travel duration and workplace location. The sensitivity analysis results show that optimum travel demand can be achieved by implementing transport policies integrated with 50% flex-time and 50% fixed-time workers arrangements.

This research aims to evaluate and improve the resilience of post-disaster multimodal intercity transportation networks to mitigate negative influences of disturbances. A comprehensive resilience performance metric, accounting for influences on unserved demand and adaptation of served demand was proposed to evaluate the resilience of multimodal transportation networks. The multimodal traffic assignment model was developed to derive the components of this comprehensive performance metric, integrating user equilibrium and modal split, while considering the capacity upper bound of some links. A route-based link recovery sequence was also proposed to improve network resilience, taking into account interdependencies and utilization of damaged links. The operational measure of capacity enlargement of functioning links was adopted to supplement the recovery sequence. The proposed resilience evaluation and improvement method was applied to a multimodal transportation network, namely, the constituent road, rail, and air networks in the Beijing–Tianjin–Hebei–Shandong region. Results show that the proposed route-based strategy outperforms volume-based, betweenness-based, and random strategies in enhancing resilience. Capacity enlargement of functioning links can further improve resilience by accommodating more affected demand, particularly effectively in scenarios characterized by inefficient repair sequences, higher fixed demand and a larger punishment multiplier. These findings highlight the interdependencies of links in establishing the recovery sequence, capacity enlargement in challenging scenarios, and enhanced availability and convenience of transportation modes to promote multimodal network resilience after a disruption.</p></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":null,"pages":null},"PeriodicalIF":6.3,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142151249","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}
