Title:The Problem of Taffic Flow and Highway Capacity
Abstract:Highway capacity refers to the maximum traffic flow within a certain period of time, that highway facilities can handle within a specific traffic condition, road condition, and human measurement standard. Highway capacity is closely related to traffic flow and is a fundamental parameter for conducting traffic management. This report presents an overview of the origin, content, methods, communication, existing achievements, and future research prospects of the study on traffic flow and highway capacity, hoping to draw everyone's attention.

Title: Automated Vehicles: Recent Developments and Local Policy Implications
Abstract: The past few years have seen new developments in automated vehicle (AV) technologies and commercialization. However, unconstrained autonomous driving remains an aspiration, and little progress has been made in AV connection and system coordination. Nevertheless, applications of existing AV technologies, including the increasingly more intelligent driver assistance systems and most notably robotaxis, are making driving less labor intensive, especially for urban passenger travel. We provide updated policy recommendations on strategic planning, public-private collaboration and robotaxi regulation for cities to best leverage and adapt to these developments.

Title: Running Safety Analysis of High-Speed Train Operation on Bridges During Earthquakes
Abstract: With the rapid development of high-speed railways, the issue of operational safety for high-speed trains traversing bridges during earthquakes is becoming increasingly prominent. Due to the problems existing in current mainstream derailment indicators for the safety assessment and stochastic analysis of train operation under seismic conditions within the wheel-rail contact state, this paper proposes, for the first time, a method for evaluating the seismic operational safety based on the stochastic response of the train-track-bridge system. A detailed wheel-rail contact model is established to calculate time-varying contact points and contact forces. Meanwhile, a stochastic vibration analysis framework for derailment of the train-track-bridge system is developed. The dynamic performance of a multi-span prestressed simply-supported box girder bridge under random seismic excitation is studied, and operational safety indicators are proposed for assessing the seismic operational safety of high-speed trains.

Title: Use of Cellular Concrete Air Convection Embankment in Permafrost Regions
Abstract: For over three decades, crushed-rock air convection embankments (ACEs) have been used to stabilize permafrost and prevent thaw settlement in roadway infrastructure. However, the high cost of importing suitable rock to remote regions like interior Alaska has limited their widespread application. This study investigates cellular concrete as a viable and superior alternative material for ACE construction. Through laboratory testing, modeling, and numerical simulation, the thermal performance and feasibility of cellular concrete ACEs were systematically evaluated. The research demonstrates that cellular concrete ACEs offer enhanced thermal stability and a better cost-benefit ratio compared to conventional embankments. Specifically, they effectively mitigate moisture warping and temperature curling in the asphalt layer. A proposed design using hollow cellular concrete blocks significantly enhances winter air convection for subgrade cooling and improves summer thermal insulation. This approach proves highly effective in controlling thaw settlement in ice-rich permafrost, facilitating future implementation and construction.
