Many studies divide a day into intervals to account for the dynamics of travel time. However, the intervals used in these studies are insufficient to capture the gradual and fine-grained changes in passenger travel patterns. This study proposes an adaptive dynamic route inference model (ADRIM) that overcomes these limitations. In the ADRIM, we introduce a constrained Expectation Maximization algorithm (CEM) by confining the parameters of the mixture log-normal distribution model (MLND) within confidence intervals, thereby reducing anomalous estimations. We use the concept of Hidden Markov Models (HMMs) to achieve a parameter-adaptive characterization for the dynamics of route choice and travel time distributions for MLND through an iterative process. For a Nanjing metro case study, the proposed model exhibits superior performance in fitting the actual distribution of travel times and accurately captures the dynamic trends in route travel times. Besides, it is revealed that the maximum difference in expected travel times among multiple valid routes for the same origin–destination (OD) pair primarily falls within the interval [5 min, 15 min], and the distribution range of the maximum ratio is mainly between [1.1, 1.6]. The high consistency in passenger route choice proportions observed for two consecutive weeks, along with an analysis of route choice patterns under dynamic conditions, serves as strong evidence supporting the reliability and practical utility of the dynamic route inference model in understanding and managing metro passenger flows.</div></div>","PeriodicalId":54417,"journal":{"name":"Transportation Research Part C-Emerging Technologies","volume":"171 ","pages":"Article 105007"},"PeriodicalIF":7.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143096522","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}

The use of charging stations, to/from which service vehicles are transported by the riders for charging, poses as a promising approach because it reduces the need for dedicated staff or contractors. However, unique challenges also arise, as it introduces docked vehicles at these stations to the existing dockless systems, and now riders can pick up and drop off e-scooters at both random locations and fixed charging stations. This requires incentives for riders to drop off vehicles at the stations and management strategies to efficiently utilize the vehicles at the stations. This paper focuses on such mixed operations of docked and dockless e-scooters as an example. It develops a new aspatial queuing network model for vehicle sharing and charging to capture the steady-state e-scooter service cycles, battery consumption and charging processes, and the associated pricing and management mechanisms in a region with uniform demand. Building upon this model, a system of closed-form equations is formulated and incorporated into a constrained nonlinear program to optimize the deployment of the service fleet, the design of charging stations (i.e., number, location, and capacity), user-based charging price promotions and priorities, and repositioning truck operations (i.e., headway and truck load). The proposed queuing network model is found to match very well with agent-based simulations. It is applied to a series of numerical experiments to draw insights into the optimal designs and the system performance. The numerical results reveal strong advantages of using charging stations for shared dockless electric micro-mobility services as compared to state-of-the-art alternatives. The proposed model can also be used to analyze other micromobility services and other charging approaches.</div></div>","PeriodicalId":54417,"journal":{"name":"Transportation Research Part C-Emerging Technologies","volume":"171 ","pages":"Article 104989"},"PeriodicalIF":7.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143096394","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}

These airports, known as slot-coordinated airports or Level 3 airports, provide a certain number of airport slots to airlines. The number of slots in a given time period — for example, 15 min or 1 h — is generally referred to as declared capacity. Only those airlines that obtain airport slots can schedule regular flights at the given airport for the next summer or winter season. Much effort has been made to optimize allocation schemes for the slot coordinator, such that airport slots are distributed to airlines efficiently and effectively. However, few attempts have been made to determine optimal airport declared capacity, mainly because of two challenges. First, the stochastic nature of airport operations due to uncertainty. Second, the unclear relationship between the economic benefits gained by scheduled flights and the possible cost induced by congestion or lost revenue due to unused airport capacity. This paper presents a novel approach for determining airport declared capacity. First, we present a K-medoids-DTW method to cluster airport capacity scenarios and a step-queuing pricing mechanism based on the zero-queuing pricing model to quantify the cost of operations in different time periods of the day. A two-stage stochastic programming model is then developed to determine the number of slots at the airport. A busy international Level 3 airport in Asia is used as a case study to demonstrate the applicability of this model. Our results highlight the advantages of the step-queuing pricing model (SPM) compared with the uniform pricing model (UPM). The SPM allows more slots to be created.

Real-time traffic safety models have the potential to capture this variation in traffic flow to predict crashes reliably, but data collection methods used in previous studies cannot effectively reflect the necessary spatio-temporal traffic dynamics. Floating car data (FCD), utilizing the kinematics information collected by multiple single vehicles, provides a way to acquire this information on traffic flow before crashes occur. This study aims to develop a real-time crash prediction model based on FCD from the Jiading-Jinshan and Outer Ring Freeways in Shanghai, China. A map matching technique is employed for freeway FCD without heading direction. Both dynamic and static features are constructed, and the variations of dynamic features before the crash are analyzed. The non-parameter tests (Mann–Whitney U and Fligner–Killeen tests) are applied to identify the heterogeneity between crash and non-crash cases. The bidirectional long short-term memory network (LSTM) with a multi-head attention mechanism combined with dynamic and static features is built and showed the best performance. Different histogram-based threshold selection methods are compared. The trained model is applied to all the data for validation, and the matched case-control technique can well predict crashes in this study. The main findings are: (1) the multi-head attention and bidirectional mechanisms can significantly improve model performance, while the static features combination is not as effective; (2) volume is the most important dynamic feature, then is the speed standard deviation followed by the average speed.

While this strategy is motivated to promote transparency, fair pricing, and participant satisfaction, it faces a particular challenge to ensure riders and drivers truthfully report their valuations, which are considered private information. To encourage truthful reports, we implement the Vickrey–Clarke–Groves pricing policy augmented with unit reserve prices, referred to as VCG-URP. For the riders, the reserve price is set as the minimum WTP per unit distance, while for the drivers, it is the maximum WTA per unit distance. We demonstrate that VCG-URP ensures that riders provide truthful valuations. However, it does not guarantee the same level of honesty from drivers in reporting their valuations. While drivers cannot enhance their utility by overstating their unit WTA, they may benefit from understating it. These theoretical results are confirmed by numerical experiments with several additional findings: (i) although the under-reporting strategy of the drivers theoretically has an opportunity to achieve a higher utility, it always leads to a decrease in expected utility over randomly generated matching scenarios; (ii) the introduction of reserve prices has larger impacts on riders than drivers and benefits the platform in excluding less profitable trips; and (iii) the performance of VCG-URP is reasonably robust towards the market density, while the VCG price is less applied when the market becomes sparse, mainly due to the loss of substitutability among participants.

To accurately characterize and mitigate these cascading effects during the collaborative lane-changing process of CAVs, we propose an Intentional Hyperedge Game Model (IHGM) grounded in hypergraph theory. The model consists of three critical modes: gap sorting, the intention boundary, and the hyperedge game. First, gap sorting prioritizes the order of gap selection for the target vehicle by assessing the benefits. Second, the intention boundary delineates the safety constraints associated with lane changes, integrating the lane change intentions of the target vehicle with the driving statuses of neighboring vehicles. Finally, the hyperedge game effectively simulates the cascading effects generated by CAVs throughout the lane-changing process. The traffic flow data of Beijing’s Second Ring Road, which were collected in 2019 for a period of seven days, were used as inputs in our case study. The results show that the IHGM significantly reduces the cascading effects and improves the lane-changing success rate by approximately 10 % in high-density scenarios, ensuring safety and comfort. The lane-changing success rate is related to the Lane-changing Position (LP), which is the distance between the target vehicle and the no lane-changing area. When the LP is 50 m, the probability of identifying a feasible path for the target vehicle exceeds 30 %, and the lane-changing success rate is 100 % when there is a feasible path. Furthermore, when the first three lane-changing target gaps are evaluated, the model effectively solves more than 92 % of the actual lane-changing scenarios and greatly reduces the impact of cascading effects.
