Such data-level consideration depends heavily on the quality and quantity of data, failing to take into account the scenario-level features behind similar scenarios. In this paper, we provide a scenario-level knowledge transfer framework for motion planning of autonomous driving, named SceTL. By capitalizing on successor representation, a general scenario-level knowledge among similar scenarios can be captured and thereby recycled in different traffic scenarios to empower motion planning. To verify the efficacy of our framework, a method that combines SceTL and classic artificial potential field (APF), named SceTL-APF, is proposed to conduct global planning for navigation in static scenarios. Meanwhile, a local planning method combining SceTL and motion primitives (MP), SceTL-MP, is developed for dynamic scenarios. Both simulated and realistic data are used for verification.

This research aims to develop a Lane-Free Following (LFF) framework to address behavior planning for AVs in environments lacking clear lane markings. The LFF utilizes decision modules, such as Monitoring Zones, Focus Zones, and Passing Corridors, to dynamically select the most appropriate following strategy. It integrates a Multi-Target Following Model (MT-IDM) and an attention allocation mechanism to optimize acceleration control by adjusting attention concentration levels. Initially, we examine the stability of multi-target following and determine the stability region on a two-dimensional plane using specific stability criteria. Subsequently, the LFF is integrated with the lateral model of the Intelligent Agent Model (IAM), and calibrated and validated using lane-free traffic data from Hefei, China, and Chennai, India. Simulation results demonstrate the LFF’s high accuracy across various vehicle types. In simulations conducted on open boundary roads and virtual circular roads with varying widths and traffic densities, the LFF showed enhanced driving comfort and efficiency. This optimization of road widths and densities improved traffic flow and road space utilization compared to traditional lane-based traffic. In congested start conditions on circular roads, we compared the uniform attention allocation mode (LFF-UA), the concentrated attention allocation mode (LFF-CA), and the High-Speed Social Force Model (HSFM). Results indicated that the HSFM excels in velocity and flow, offering faster startup efficiency. The LFF-UA, while maintaining efficiency, evenly distributed attention to neighboring preceding vehicles, enhancing driving safety and reducing fuel consumption and emissions.

However, most previous studies optimize the connected automated vehicle’s (CAV) communication and control systems individually, ignoring their collaboration and cascade effects. To address this gap, we present the Traffic-Communication Coupling Control (T3C) approach for joint optimization of CAV trajectories and communication networking. The roadside unit (RSU) periodic intervention mechanism and the edge-end collaborative computing architecture are utilized to adapt the AIM system’s multi-type computational tasks. The approach creates a relay CAV identity assignment module to provide a linkage pattern between communication networking and CAV control. Following that, CAVs utilize a distributed trajectory planning approach to plan their trajectory states, with parallel distributed model predictive control applied on a rolling horizon. The RSU collects and transmits the trajectory states to the mobile edge computing (MEC), which optimizes communication networking. To quickly solve the networking scheme, the task is divided into two sub-problems: backbone network generation based on the traffic-information flow coupling mechanism and information flow distribution. These two sub-problems are handled using the adjacency matrix masking optimization approach and enhanced adaptive large neighborhood search (ALNS) algorithm, respectively. Numerical studies are carried out to confirm the effectiveness of the proposed approach in various vehicle arrival rate scenarios. The results demonstrate that T3C can ensure stable low-delay communication while improving traffic efficiency, particularly in high vehicle arrival rate scenarios.

Therefore, this paper focuses on the integrated rescheduling of the train timetable and rolling stock circulation in an urban rail transit line under rolling stock faults. Three typical scenarios arising from such faults are studied simultaneously, i.e., delay, out-of-service, and rescue. Taking general key practical constraints and scenario-specific constraints into account, multi-objective mathematical models are formulated for each scenario to optimize various dispatching measures, such as retiming, cancellation, short-turning, and backup rolling stock utilization. For computational tractability, the proposed models are transformed into equivalent mixed-integer linear programming (MILP) reformulations using some linearization techniques. In order to satisfy the real-time requirements of train rescheduling, a data-driven approach is developed to accelerate the solving process by fixing some decision variables in advance. Specifically, the prediction of binary variable values is treated as a classification task. After creating a dataset including different rolling stock faults and their respective optimal solutions generated by GUROBI, the correlations between optimal solutions and instance features are extracted through supervised learning based on the multilayer perceptron. By generalizing the extracted correlations to unseen instances, high-quality solutions can be found in a short time. Finally, numerical experiments are carried out based on the Beijing Yizhuang Metro Line.

To address this challenge, this paper presents a two-level hierarchical control framework for mixed traffic environments, consisting of both CAVs and human-driven vehicles (HVs), offering a computationally efficient solution without compromising performance. At the upper level, we introduce a platoon-based mixed integer linear programming (PMILP) model to jointly optimize signal timing and desired arrival times, with the main objective of minimizing traffic delay.

Existing methods aim to reconstruct STTD using low-dimensional models. However, they are limited to data-specific dimensions or source-dependent patterns, restricting them from unifying representations. Here, we present a novel paradigm to address the STTD learning problem by parameterizing STTD as an implicit neural representation. To discern the underlying dynamics in low-dimensional regimes, coordinate-based neural networks that can encode high-frequency structures are employed to directly map coordinates to traffic variables. To unravel the entangled spatial–temporal interactions, the variability is decomposed into separate processes. We further enable modeling in irregular spaces such as sensor graphs using spectral embedding. Through continuous representations, our approach enables the modeling of a variety of STTD with a unified input, thereby serving as a generalized learner of the underlying traffic dynamics. It is also shown that it can learn implicit low-rank priors and smoothness regularization from the data, making it versatile for learning different dominating data patterns. We validate its effectiveness through extensive experiments in real-world scenarios, showcasing applications from corridor to network scales. Empirical results not only indicate that our model has significant superiority over conventional low-rank models, but also highlight that the versatility of the approach extends to different data domains, output resolutions, and network topologies. Comprehensive model analyses provide further insight into the inductive bias of STTD.
