Distinguishing between the travel choice behaviors of passengers who board the first arriving train (Type I passengers) and those who are left behind (Type II passengers) in passenger assignment is essential for effective URT passenger management. This paper proposes a data-driven passenger-to-train assignment model (DPTAM) that leverages automated fare collection (AFC) data and automated vehicle location (AVL) data to differentiate between the travel choice behaviors of the two types of passengers. The model comprises two modules based on passenger travel choice behavior: the passenger route choice model (PRCM) and the passenger itinerary choice model (PICM). The PRCM employs a granular ball–based density peaks clustering (GB-DP) algorithm to estimate passengers’ route choices based on historical data, enhancing precision and efficiency in passenger classification and route matching. The PICM incorporates tailored itinerary selection strategies that consider train capacity constraints and schedules, enabling accurate inference of passenger itineraries and localization of their spatiotemporal states. The model also estimates train loads and left-behind probabilities to identify congested periods and sections. The effectiveness of DPTAM is validated through synthetic data, demonstrating superior assignment accuracy compared to benchmarks. Additionally, real-world data from Chengdu Metro reveal the impact of congestion on travel behavior and effectively identify congested periods and high-demand stations and sections, highlighting its potential to enhance URT system efficiency and passenger management.</p>\u0000 </div>","PeriodicalId":50259,"journal":{"name":"Journal of Advanced Transportation","volume":"2025 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/atr/6620828","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143880163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 problems have created an urgent need for advancements in managing vehicle speeds to mitigate the negative impacts of speeding. Concerning this, strategies such as setting speed limits, traffic calming measures, police enforcement, and spot speed camera enforcement (SSCE) have been widely investigated for their suitability and impacts on speed management. Although such conventional measures are effective, depending on circumstances, in reducing vehicle speed in the vicinity of the interventions, studies have shown that their impact is limited in space, leading to the problem of event migration. The promising approaches to solving such limitations are the use of variable speed limits (VSLs), intelligent traffic calming devices, sectional speed enforcement systems (SSES), and intelligent speed adaptation (ISA) systems. Despite their limitations, conventional speed management measures are continuing to be implemented predominantly around the world because of their lower initial cost of installation and implementation.

We first conduct a questionnaire survey to explore travelers’ choice behaviors when they commute to or from URT stations, considering various influencing factors. After completing the statistical analysis, we then proceed with a preliminary assessment of the factors impacting travel mode preferences. Subsequently, a hybrid methodology that integrates structural equation modeling (SEM) and a random parameter logit model (RPLM) is introduced to investigate the impacts of factors. Notably, the interaction terms among travel time, cost, and psychological perception are considered as random variables. As a result, the heightened interaction between travel time and safety perception leads to a reduced probability of opting for walking or bike-sharing as transportation modes. Similarly, there is a notable decrease in the probability of selecting a taxi when the interaction terms of travel cost and safety perception increase.

Researchers in the transportation domain have effectively addressed the issues of poor convergence and suboptimal optimization encountered in RL for multi-intersection signal control scenarios by adopting the centralized training with decentralized execution (CTDE) approach. However, due to the heterogeneity among intersections, simply decomposing the global reward into a sum of intersection-level rewards is unreasonable, posing a challenge in balancing the interests of individual intersections and the entire road network. Additionally, the assumption that all intersections within the system make decisions synchronously is rather strong. Therefore, this paper proposes a distributed traffic model tailored for synchronous decision-making and, based on that, introduces an asynchronous decision-making traffic model according to decoupled intersection control. Simulation experiments show that the asynchronous decision-making method proposed in this paper not only improves the model convergence speed by at least 19% compared to the multiagent deep RL (MADRL) algorithm used for synchronous decision-making, but also improves the model by at least 10.5% in vehicle driving speed, maximum queue length, and average queue length within the decodable range (the traffic density is between 100 vehicles/km and 400 vehicles/km).
