Rapid quantification of the impacts of network disruptions can assist in planning recovery efforts. However, gathering timely and comprehensive information for assessing transportation network state is often challenging and not always possible. This study introduces a network assessment strategy to estimate total link capacity reduction and origin–destination (OD) demand matrix (CRDM) for disrupted transportation networks subject to limited information, i.e., link travel time accessible from smartphone-based trajectory data. The CRDM problem can be formulated as a bi-level model, optimizing estimates of externally caused capacity reduction and OD demand matrix in the upper level while solving the user-equilibrium-based traffic assignment in the lower level. The proposed bi-level model with a generalized least squares (GLS) objective (to minimize the discrepancy between observed and estimated travel times) does not yield a unique solution. Therefore, we further employ the maximum entropy principle to develop a maximum entropy-least squares (MELS) model, which has a unique solution. To solve the MELS model, we develop a tailored augmented Lagrangian algorithm and conduct numerical studies on different transportation networks (i.e., a two-link single-OD network, the Sioux-Falls network and a real-world regional transportation network). The proposed approach is able to provide a rapid post-disruption evaluation of the overall link capacity loss in transportation network under limited information, i.e., without OD demand information and with limited information on link travel time.</div></div>","PeriodicalId":54418,"journal":{"name":"Transportation Research Part B-Methodological","volume":"195 ","pages":"Article 103194"},"PeriodicalIF":5.8,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143619369","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}

Vertical structure models are proposed to capture the interactions among the stakeholders: passengers, airlines, and rail operator. In the proposed models, passenger heterogeneity is reflected by a continuous value-of-time (VOT) distribution, and the total passenger demand is given. The critical VOTs dividing the passengers into different groups by travel mode are identified, and the distributional effects of new airport and air-rail cooperation on the heterogeneous passengers are examined. The findings show that the new airport and air-rail cooperation can benefit all passengers, and these benefits vary significantly across passengers. The poorest passengers gain the most from the air-rail cooperation. However, who gains the most from the new airport depends on the transfer time and cost for the new airport service. For a relatively low transfer time and cost, the mid-income passengers gain the most. Otherwise, the low-income passengers gain the most. At a high congestion level of the hub airport, introducing a new airport is more efficient in decreasing the social cost of the system than introducing the air-rail cooperation. Conversely, at a low congestion level of the hub airport, introducing a new airport may cause an increase in the social cost of the system instead. Consequently, the decision of investing in a new airport in an MAS should be carefully made.</div></div>","PeriodicalId":54418,"journal":{"name":"Transportation Research Part B-Methodological","volume":"195 ","pages":"Article 103195"},"PeriodicalIF":5.8,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143611244","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}

By considering both aeronautical- and non-aeronautical businesses and further incorporating the non-linear relationship between queuing time in the check-in zone and shopping time in the retail zone, we find that unlike runway capacity expansion, where single-till regulation leads to underinvestment (as compared to the unregulated case), terminal capacity expansion is contingent upon traffic volumes. Under higher traffic volumes, terminal capacity expansion becomes less efficient in reducing the terminal congestion delay, thereby reducing the effect on expanding passengers’ shopping time and concession revenue. As the revenue loss is disregarded under single-till regulation, airports would overinvest in terminal capacity under higher traffic volumes, which reverses the underinvestment tendency under lower traffic volumes. Also, single-till regulation results in a later airport arrival time suggested to passengers, for which the excess concession revenue from an earlier arrival time is overlooked. By contrast, dual-till regulation tends to attract more passengers to the airport by reducing terminal and runway delays, therefore leading to lower airport charge, shorter terminal time and higher capacity. The increased ridership and enhanced utility thus improve the overall social welfare.</div></div>","PeriodicalId":54418,"journal":{"name":"Transportation Research Part B-Methodological","volume":"195 ","pages":"Article 103192"},"PeriodicalIF":5.8,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143611243","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}

We adopt the bottleneck model to study the morning commuting dynamics. In this context, we consider two potential benefits for AVs, i.e., value-of-time (VOT) compensation/reduction and capacity enhancement. We develop an extension-elimination-verification-supplement approach to simplify the equilibrium analysis process to obtain the equilibrium departure flow patterns. We find that the external uncertainty makes the equilibrium departure flow patterns more complicated than those under the deterministic setting, yielding three basic departure flow pattern types, i.e., AVs travel inside HVs, AVs travel after HVs, and HVs and AVs depart alternatively. If AVs are able to reduce VOT, their ability to improve bottleneck capacity does not qualitatively change the equilibrium departure flow patterns. Moreover, although increasing the penetration of AVs can improve the system performance to some degree, the total travel costs may not be monotonically decreasing with respect to AV penetration when AVs cannot significantly enhance bottleneck capacity. The optimal penetration rate of AVs minimizing the total travel costs is no less than 50% and the total travel costs reach the minimum in the situation with mixed HVs and AVs rather than in the 100% AV penetration if the bottleneck capacity enhancement caused by AVs is not significant enough. Furthermore, increasing the penetration of AVs may indeed increase traffic congestion when compared to that under 100% HVs if AVs cannot enhance bottleneck capacity sufficiently. To reduce total travel costs by increasing AV penetration, it is necessary to ensure that AVs can enhance bottleneck capacity sufficiently as the penetration rate of AVs increases when the adverse effects of VOT compensation on traffic congestion are dominated. When the penetration rate of AVs reaches 100%, the capacity enhancement from AVs should be sufficiently large to ensure that AVs can simultaneously improve the system performance and reduce traffic congestion.</div></div>","PeriodicalId":54418,"journal":{"name":"Transportation Research Part B-Methodological","volume":"195 ","pages":"Article 103203"},"PeriodicalIF":5.8,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143592452","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}

These fixed-length compositions are mandated to not exceed station platform lengths, thereby limiting the potential for increasing capacity to effectively accommodate oversaturated passenger demand. To this end, we focus on a flexible metro operating system equipped with extra-long train compositions, which allows trains to protrude beyond both ends of the station platforms for additional capacity. Driven by oversaturated and time-dependent passenger demand, we develop a compact integer linear programming model to determine train composition lengths and train-platform alignment relationships. When using commercial solvers to directly handle this model, complexity analyses and computational practice show that it is less efficient for large-scale experiments. We thus reformulate it as a column-based optimization model, while employing a column generation algorithm to solve its linear relaxation version and customizing a dynamic programming method to generate promising column variables. To achieve high-quality integer solutions, we carefully embed the column generation into a branch-and-bound procedure and elaborate some accelerating strategies through theoretical analyses. The approach is applied to several test instances defined by using hypothetical and real-world lines.

We introduce an exact rolling stock rescheduling algorithm and an iterative heuristic, which alternate between two mathematical formulations, namely one that creates an interim rolling stock schedule and one that tries to fit the suggested shunting movements between the remaining railway traffic. We test our solution approach with instances that contain complete railway blockages on the Dutch railway network.

To do that, we developed a Compliance-constrained Resilient System Optimal Trajectory Planning (CR-SOTP), which is devised as an event-triggered rolling-horizon system-optimal trajectory planning and replanning coupled scheme combined with a compliance incentive instrument. Specifically, we developed a bi-level optimization model (C-SOTP-BL) with the upper level (SOTP-MINLP) formulated as a mixed integer nonlinear program to generate a system optimal trajectory plan for all CAVs within a trajectory planning area around an OMM intersection, subject to the compliance constraints from the lower level (C-MINLP) optimal incentive model built upon game theory. To adapt to real-time implementation, we developed a parallel computing-aided relax-enforcement-refinement (P-RER) solution method to efficiently solve the C-SOTP-BL. Thanks to the advanced computing performance of the P-RER, the CR-SOTP approach gains resilience through the coupled rolling horizon framework, which recursively plans and replans CAVs’ trajectory by solving the C-SOTP-BL with a descending scale to respond to random disturbances. Numerical experiments employing NGSIM data confirmed the effectiveness of the solution algorithm P-RER in real-time implementation, outperforming existing commercial solvers. The CR-SOTP can generate efficient and resilient trajectory plans to ensure stream-wide safe and smooth traffic merging at an OMM intersection subject to random disturbances.
