WORDS EXTRACTING PROVIDER FOR RAIL DISASTERS

The FRA has set “a basic disinterested of zero resistance for rail-related occurrences, injuries, and fatalities”. The deliver considers know the options of the particular disasters that could tell both structure compose and policies to increase invulnerability. This study describes an analysis commit know the possible seer or contributors to pileups seized from “tapping” the plot text in rail occurrence reports. This consult evaluates the efficiency from the lineaments build from text tunneling practicing models that contains the particular functions to work out the outlay of height casualty’s. We devote two kinds of troupes: boosting and start aggregate or bagging. Boosting offers a constant purpose of mixing the outputs from the arrangement of easy or weak learners to promote a correct mixed assess. Among the key goals of text prospecting eager to indicate the items in the details about system finding. Within this report we abuse a river extension nearby the law term detail womb. Modern text report manners favor the versions in a period the pileup reports approximately as accessible for accurate report for the reason that the precise fields not beyond the reports. We engage probabilistic indexing and topic models. For PLS we early given 1000 discussion in the LDA topics. Then we begin the believed length of PLS components practicing mix-validation. Just like the OLS results, the not over this menu also disclose that the trio purposes boost in foretelling rigor adopting the subsumption of text prospecting results. Regarding the moderately text tapping PLS shows beat appearance than LDA

A New Movement Authority Based on Vehicle-Centric Communication

The communication system that is presently applied in the European Train Control System can only support data exchange between vehicles and ground, but the direct vehicle-to-vehicle communication is not available. The details of interlocking information and other vehicles’ movements are invisible to drivers who are the last defense to prevent unsafe scenarios. As connected vehicles have been envisioned to enhance transportation efficiency and improve safety, the direct vehicle-to-vehicle communication network is involved in this paper to increase the safety of railway transport. In this paper, a new train movement authority (MA+) is proposed. Apart from a wireless communication unit, this system does not require any other infrastructure. With the assistance of vehicle-centric communication technology, MA+ can detect the condition of switches and trains within a certain scope. In this paper, the system structure of MA+ is proposed. Additionally, different implementation scenarios are also discussed. The detection range is estimated and validated based on mathematical calculation and experimental equations. An application demo of MA+ is presented on the Driver Machine Interface of the onboard equipment. The results indicate that MA+ can be a flexible and scalable system for furthering the improvement of railway safety

Safety and security co-analysis in transport systems: Current state and regulatory development

Transportation is sensitive to risk. Given the fast development of digitalisation and automation of transport systems in the past decade, new types of security risks (e.g. cyberattacks) emerge within the context of transport safety research. To enable the integrated analysis of emerging security and classical safety-related risks in a holistic manner, safety and security co-analysis (SSCA) is highly demanded for accident prevention. SSCA in transport systems will benefit the risk analysis of complex cyber physical transport systems facing challenges from both hazards and threats. However, the nature of hazard and threat-based risks is fundamentally different, which leads to the various difficulties of analysing them on the same plane. They include the use of different risk parameters, the uncertainty levels of the risk input and the methodologies of risk inference. To address such concerns, this study firstly reviews the literature on SSCA and compares the employed methodologies and their applications within the context of transport systems. Taking into account the advantages of both security-driven and safety-oriented methods, a conceptual framework is proposed to imply the insights on SSCA for transportation through both top-down and bottom-up perspectives, followed by a quantitative illustrative case study. Then, the regulatory development and evolution of SSCA in transport in practice is analysed across different transport modes, which configures initiatives’ interrelations for a cross-fertilisation purpose. As a result, the findings reveal new research directions for the safety of digitalised and/or autonomous transport vehicles and aid in the formation of future transport safety study agendas
