But what, exactly, are the current foundational concepts and methods? This paper fills a gap in the literature and sets the stage for the special issue by documenting the current state of passenger travel modeling practice. A 2007 article published in this journal described what was then the current state of the practice and suggested future directions for what was then the relatively new “activity-based” modeling paradigm (Davidson et al., 2007). These models have now reached maturity in the United States. One outcome of this maturity is that model developers and model owners are less likely to publish their methods in academic journals than during the earlier years of activity-based model development. Researchers must therefore seek out agency model documentation to understand the state of travel modeling practice, which is rarely done. We seek to address this information gap by documenting the current state of the practice in activity-based travel modeling, with references to relevant practical modeling systems, and reflect on the evolution of practical models since their initial deployments. These references can be used by academics as “baselines” to demonstrate the comparative value of new foundational concepts and methods. We also identify and discuss obstacles to widespread adoption of activity-based models and suggest research threads that would add value to travel modeling practice.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"169 ","pages":"Pages 1-8"},"PeriodicalIF":6.3,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143882420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilizing an empirical dataset of 51,454 <span>UAD</span> offenders in Taiwan over an eight-year period (2014–2021), the analysis results support the hypothesis that greater accessibility to the bus transit network significantly decreases the likelihood of recidivism among naïve offenders, particularly among older adolescents. The findings also reveal that UAD offenders residing in economically disadvantaged neighborhoods are more likely to engage in subsequent offenses compared to those in more prosperous areas, underscoring the importance of enhancing transit services from a social equity perspective. Additionally, consistent with patterns observed in recidivism for other traffic offenses, male offenders and individuals with prior UAD violations are at a higher risk of repeat offenses. These results emphasize the need for targeted interventions within graduated driver licensing programs. This study highlights the significance of early identification and intervention for UAD offenders, particularly through differentiated approaches for naïve and repeat offenders. The proposed multilevel zero-inflated modeling approach proves valuable in distinguishing between offender types and offers potential for application in other traffic recidivism contexts.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"168 ","pages":"Pages 168-181"},"PeriodicalIF":6.3,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143851896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to analyze the spatiotemporal evolution and robustness of China's Air Cargo Network (CACN) using monthly operational data. The research employs complex network theory to examine spatial and temporal dynamics, integrates multiple central indicators for evaluating node importance, and assesses network robustness under various attack scenarios. Our study demonstrates that China's air cargo network faces challenges such as low route execution rates, an unstable structure, and significant cargo flow imbalances—particularly in low-traffic areas. Strategic hubs, such as Urumqi (URC), Kunming (KMG), Hangzhou (HGH), Shenzhen (SZX), and Nanjing (NKG) play vital roles., while the rise of Ezhou Huahu Airport (EHU) alleviates network pressure on major hubs. Moreover, our analysis reveals a distinct differentiation in hub airport roles, with the network exhibiting scale-free and small-world characteristics. The robustness of the network is shown to vary depending on the type of attack strategy employed, underscoring the need for targeted interventions to enhance overall network efficiency and resilience. Key findings reveal that CACN has a low route execution rate and an unstable structure, with significant cargo flow imbalances, especially in low-traffic regions. Additionally, CACN shows scale-free and small-world characteristics, with network robustness varying under different attack strategies.

However, one area of limited research so far is on the impact of parking constraint at workplace on its spatial-temporal design. This paper examines a multi-modal morning commute scenario, where commuters can freely choose solo driving, carpooling, or public transit to go to work. The highway bottleneck capacity is shared between a general-purpose lane for all drivers and a time-limited carpool lane for carpooling vehicles only. Analytical derivations of all possible commute patterns are provided, considering different parking supply levels and capacity allocation strategy. Results show that all bottleneck capacity should be allocated to carpool lane spatially, but the optimal temporal allocation of carpool lane may not be unique for minimizing total trip cost. This implies, the accurate estimation of extra carpool cost to optimize the temporal lane reservation may be no longer necessary for the traffic authority due to the limited parking supply, whilst it is really required when the parking supply is abundant. We also incorporate the traffic authority's social cost budget for both temporal and spatial allocations into the optimization problem, explaining why general-purpose lanes are still prevalent in reality. The research has implications on policy makers as well as workplace parking managers by providing them a framework to design optimized road-space allocation with workplace parking supply.</div></div>","PeriodicalId":48378,"journal":{"name":"Transport Policy","volume":"168 ","pages":"Pages 157-167"},"PeriodicalIF":6.3,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143848663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
