Simulation Model Based Response Management Related to Railway (Earthquake) Disaster

Railway system as part of the general transportation system is a strategic element that supports the economy and the society. Its role is continuously rising with rapid industrialization, urbanization, and changes in the society expectations regarding sustainable systems. New and emerging technologies call and permit the augmentation of the railway systems’ disaster management. This paper deals with the development of an improved response management concept related to railways’ damage, caused by earthquakes. The paper synthetizes the latest technologies, engineering, and management methods in one improved response management system. After the concept inspiration, the paper describes the applicable novel models and introduces an improved response management being developed for railway systems, damaged by earthquakes. The concept is verified in simulation. The novelty includes a new approach in the identification of the critical infrastructure, the risk assessment, the prediction of aftershocks and the recursive application of the adaptive Markov process to the simulation supporting the response management concept

Total impact evaluation of transportation systems

Impact assessment, in general, includes the environmental safety and security considerations, and cost/cost-benefit analysis of the used sources. As usual, the impact is evaluated at two levels: (1) impact during operation (usage) related to a chosen operational unit (e.g., running distance [km], operational time [h] or calendar time [h]), (2) the life-cycle (project life-cycle) impact. The environmental impact is characterized by the chemical and noise emissions. Safety and security are estimated by risks. Costs are calculated based on the required financial support and caused losses. All these calculations are related to the individual vehicles or vehicles with average behaviours. The investigation of sustainability impact requires a wider evaluation and approach, for example, by also including production and recycling beside the operational aspects. This paper generalizes the impact analysis. At first, it considers all types of impacts including the direct (e.g., accidents) and indirect long-term effects (e.g., health problems caused by emissions). All the impacts are expressed as costs. The defined Sustainable Transportation Performance Index (STPI) is the Total Life-Cycle Cost (TLCC) related to the unit of transport work. As such, it combines the life-cycle emissions evaluation and transport costing methods. It contains the total operational and total impact costs. The proposed approach introduces three new specific features in the impact analysis: (1) the impact is evaluated on the transportation system level, (2) the impact is estimated as the total value (including all the related sub-systems and elements, like vehicles, transport infrastructure, transport flow control, etc.), (3) proposes a unique index to describe the total impact. The paper describes the general equations and the developed methodology for the estimation of the total impact and analyses its applicability. The preliminary results demonstrate the applicability of the defined index and its evaluation methodology. It also shows the limitations of traditional cost models. Further test results and wider application of the methodology will be provided in a series of follow up papers by the research team

Az autonóm felszíni közlekedés biztonságának növelése UAV-rendszerrel gyűjtött meteorológiai információk figyelembevételével

Ez a tanulmány a UAV-eszközök felhasználásának lehetőségeit elemzi meteorológiai adatok gyűjtésére, az adatokból pontosított előrejelzések generálására és ezek hasznosítására, elsősorban az autonóm közúti közlekedésben. Ma jelentős hiány mutatkozik a planetáris határrétegben mért adatokban, ezek ismerete kulcsfontosságú a pontosabb előrejelzésekhez, hiszen ez az időjárást befolyásoló föld-légkör interakciók zónája. A mai dróntechnológiával az adatok megfelelő térbeli és időbeli felbontással gyűjthetők, Magyarországon 15 mérőállomásból álló adatgyűjtő rendszer képes 90% lefedettséget biztosítani. Az időjárás-előrejelző rendszerek piaca 22 milliárd HUF gazdasági-társadalmi értéket képvisel, a rendszer fejlesztésével ez az érték mint piac hasznosítható. Az autonóm járművek jelenlegi technológiai szintje mellett a legfontosabb kérdés az útszakaszok azonosítása, ahol a járművek autonóm funkciói biztonságosan használhatók az adott időjárási körülmények mellett, és a rendszer használatával ez az információ a közúti felhasználókkal megosztható

Fundamental Elements of Drone Management Systems in Air Traffic Planning

Drones or Unmanned Aerial Systems (UAV – Unmanned Aerial Vehicles or UAS – UnmannedAerial Systems) are vehicles that can fly without the need for a pilot or passengers. Drones can be controlled remotely through radio waves or independently (with a previously determined route). The amount of documented accidents involving the hazardous use of drones has risensignificantly due to the increased usage of drones. To perform and increase the use of drones in air traffic management (ATM), especially in smart city planning, a variety of regulations andmanagement procedures will be implemented. This paper aims to propose management rules or regulations for drones in smart city transportation management and some approaches related to drone management and drone control. To present controlling approaches through the parameters in mathematical modelling for drones, we need a control rule, data gathering from the surroundings (usage of GIS), and a dynamic model of drones, and to present controlling and managing it with the help of a drone-following model based on a dynamic model of drones

Towards Sustainability in Air Traffic Management

The International Civil Aviation Organization is estimated that the number of domestic and international passengers will be expected to reach six billion by 2030. This exponential growth in air transport has resulted in a wide range of adverse effects such as environmental impacts. The purpose of this research is to develop new air traffic management, and operator (pilots, air traffic controllers) load measuring systems in order to save fuel, and flight time, thereby reducing environmental impact, carbon emission, greenhouse gas generation, noise pollution, and operating cost. This paper deals with: (i) dynamic sectorization and airspace configuration (ii) introduction of the highly dynamic approach and landing procedures, (iii) dilemmas of human in sustainability (related to the individuals, the society, the non-governmental organizations, and the managers), and (iv) development of dedicated non-intrusive operator supporting systems based on eye-tracking, heart rate, and electrodermal activity. Due to the consequent effects of these developments, the dynamic sectorization and air space configuration may eliminate the task overload and reduce the actual operator load by 30–40%. With the developed concept of dynamic approach and landing procedures, aircraft will be able to follow better trajectories to avoid residential areas around airports to (i) reduce ground noise, and emission, (ii) avoid encounters severe weather and prevent incidents and accidents, and (iii) decrease landing distance up to 56% in compared to the “published transition route”

Feasibility Study of Flight Centric Mode of Operations - A Human Performance Approach

We investigated the operational feasibility of Flight Centric ATC with a Real-Time Simulation in an area covering Budapest Area Control Centre between FL325 and FL660. This exercise specifically looked into single-person operations, where the ATCOs fulfilled the roles of conventional Planning Controllers and Executive Controllers. From a Human Performance perspective the main goals of the validation exercise were to collect controllers' feedback regarding i) the set-up of responsibilities and tasks allocated to them, ii) the impact of the changes in operating procedures on human performance, including controller's trust, workload and situational awareness and finally, iii) assess the display design for presenting the Flight Centric airspace on the controller working position. The results clearly show that the new concept has significant impact on situational awareness. In order to support controllers, reliable and transparent Flight Centric-specific system support is essential, which has to be further refined. Data also indicate that whilst workload remained at acceptable levels, major contributing factors were coordination needs and management of the new tools. The paper outlines the conclusions and recommendation for the next phase of research
