Research on wheel-rail noise in rail corrugation road of urban rail transit

E3S Web of Conferences
As an efficient, fast, green and environmentally friendly means of transportation, subway vehicles account for the largest proportion of urban rail transit, and in large and medium-sized cities, the construction of subway is still in rapid development, but with the subway noise radiation problem, subway noise plagued by passengers, related operators ...

A Review of Urban Rail Transit PPP Research

BCP Business & Management, 2022
To relieve the pressure of government investment and high-cost operation in major infrastructure projects, the PPP (Public-Private Partnership) is widely used in transportation engineering projects, especially urban rail projects. In this paper, we use Excel and Citespace software to categorize the research hotspots and analyze the trend changes to ...

Ungulate substrate use in fauna passages

Wildlife Biology, EarlyView.
Fauna passages are increasingly constructed at major roads and railways to mitigate the negative effects of infrastructure and traffic on wildlife. The function of such passages depends on design, including the construction materials, soil, and vegetation.

Graph neural network‐based attack prediction for communication‐based train control systems

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract The Advanced Persistent Threats (APTs) have emerged as one of the key security challenges to industrial control systems. APTs are complex multi‐step attacks, and they are naturally diverse and complex. Therefore, it is important to comprehend the behaviour of APT attackers and anticipate the upcoming attack actions.

An Overview of High‐Temperature Superconducting Cables in DC Systems: Unlocking Potential for High‐Voltage DC Networks

High Voltage, EarlyView.
ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...

Study of Urban Rail Transit Operation Costs

Procedia - Social and Behavioral Sciences, 2013
AbstractIn order to analyze variation of urban rail transit (URT) operation cost against the distance from the city center, the URT of Shenzhen was taken as an example to study in the three cases. The costs of URT operation were addressed through the real data of URT, and the skeleton planning method was used to estimate the costs of Shanghai and ...

The future of regional airports in Australia: Policy challenges

Australian Journal of Public Administration, EarlyView.
Abstract Council‐owned regional airports in Australia face governance challenges that have caused significant financial unsustainability across the sector. Federal policy frameworks fail to address these challenges and risk exacerbating existing pressures by outlining ambitious visions for the adoption of new technologies and achieving net zero.
