It has proven to be an effective way of reshaping peak-hour travel demand, allowing workers to alter their departure time. 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. The results showed that the departure time reaches its peak at 7:30 am. The departure time distribution of non-teleworkers is statistically significantly different from hybrid workers and passive non-teleworkers. 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. The proposed methods will contribute to developing a tool to test the effect of various flex-test arrangements on peak-hour travel demand. This study will assist transport planners and policymakers in achieving optimum employer-based travel demand management.</p></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"190 ","pages":"Article 104229"},"PeriodicalIF":6.3,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0965856424002775/pdfft?md5=a42415425f2e5fdde28e9c69e6eb23f9&pid=1-s2.0-S0965856424002775-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142158459","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}

Resilience reflects the performance of a multimodal transportation network after suffering from a disaster, and the failure of this network influences the public life and induces economic losses. 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":"189 ","pages":"Article 104243"},"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}

While exogenous shocks such as economic recessions and pandemics are attributed to such turbulence, the changing shipping market structure with the formation of shipping alliances could also play a moderating role. The US government has begun to stipulate stricter policies that restrict shipping alliance development and aim to stabilize the freight rate. In this paper, we examine how shipping alliances can moderate freight rate volatility in the container shipping market. An analytical economic model is first derived to generate theoretical predictions, and an empirical study is then conducted by using real-world shipping market data to verify the theoretical predictions. Specifically, our analytical results suggest that shipping alliances can aggravate the volatility of freight rates when the market shock is from the demand side while alleviating the volatility caused from the supply side. Moreover, shipping alliances always lead to lower volatility in port charges. When the shipping demand (or shipping fuel price, respectively) is stochastic, the alliance-induced cost savings through economies of scale have no impact (or increases, respectively) on differences in volatility in both port charges and shipping freights with and without a shipping alliance. On the basis of panel data of 10 selected Chinese major container shipping routes from 2010 to 2021, a panel data regression model with two-way fixed effects (TWFE) is estimated. The empirical results confirm our analytical conclusions. We construct an integrated economic model to reveal that shipping alliances can affect market risk in a rather implicit way, i.e., through freight rate volatility, which has not been explored. Moreover, our empirical study results support the theoretical results and accurately quantify the impacts of shipping alliances on main international container shipping routes, thereby providing related policy implications for regulators.</p></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"189 ","pages":"Article 104231"},"PeriodicalIF":6.3,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142122882","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}

We consider a multimodal transportation network, where a micromobility platform deploys docking stations and operates a fleet of micromobility vehicles to provide shared micromobility services and a public transit agency offers transit services over a transportation network. A market equilibrium model is developed to capture the intimate interactions among access and egress times of shared micromobility services, waiting times of transit services, the spatial distribution of docking stations, passenger demand, platform pricing and fleet sizing, vehicle repositioning and the micromobility platform profit. The platform decision problem is cast as a high-dimensional non-convex program. A solution method is proposed to efficiently compute the solution through problem reformulation and dimensionality reduction. Based on the proposed framework, we evaluate spatial equity in transport accessibility using the Gini index, and find that although shared micromobility improves overall transport accessibility, the benefits are not fairly distributed across different geographic zones, which leads to enlarged spatial inequity gaps after introducing shared micromobility. To promote transport equity, we investigate three policy directions: (a) to impose a vehicle density floor on shared micromobility; (b) to offer a subsidy on shared micromobility rides for first/last-mile connections; and (c) to promote collaboration between public transit and shared micromobility. We show that different regulatory policies have advantages and limitations. The minimum vehicle density requirement can simultaneously improve spatial equity and passengers’ surplus, but has limited equity improvements. In contrast, the subsidy on bundled services could significantly mitigate spatial inequity, but it hurts passengers and the platform profit. Compared to the other two policies, the transit-micromobility collaboration can lead to higher equity improvement, higher passenger surplus, while offering a guarantee on the platform profit, which turns out to be the most cost-effective approach. These insights are validated through realistic numerical studies for San Francisco.</p></div>","PeriodicalId":49421,"journal":{"name":"Transportation Research Part A-Policy and Practice","volume":"189 ","pages":"Article 104225"},"PeriodicalIF":6.3,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142095300","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}
