Matthes, Sigrun (author), Lührs, Benjamin (author), Dahlmann, K. (author), Linke, F. (author), Grewe, V. (author), Yin, F. (author), Shine, K.P. (author)Aviation can reduce its climate impact by controlling its CO2-emission and non-CO2 effects, e.g. aviation-induced contrail-cirrus and ozone caused by nitrogen oxide emissions. One option is the implementation of operational measures which aim to avoid those atmospheric regions that are in particular sensitive to non-CO2 aviation effects, e.g....abstract 2020

Van Doorn, E.C. (author), Horvath, I. (author), Rusak, Z. (author)This paper presents a systematic approach towards the study of required situation awareness (RSA) in traffic management context. Current theories are not suitable to clearly define the RSA in complex man-machine interaction (MMI) contexts. Deficiencies of man-machine interaction are difficult to recognize and resolve. This paper analyzes: (i)...conference paper 2014

Kecman, P. (author), Corman, F. (author), D'Ariano, A. (author), Goverde, R.M.P. (author)In the last decades of railway operations research, microscopic models have been intensively studied to support traffic operators in managing their dispatching areas. However, those models result in long computation times for large and highly utilized networks. The problem of controlling country-wide traffic is still open since the coordination...conference paper 2012

Klunder, G.A. (author), Taale, H. (author), Kester, L. (author), Hoogendoorn, S.P. (author)This paper introduces a topic which is of growing interest in the traffic control and management community, namely the relation between traffic data quality and the efficiency of traffic management. After some explanatory background and state of the art, it will become clear that no standard approach is available for traffic engineers to...conference paper 2014

Meurs, H. (author), Van Wee, G.P. (author), Perdok, J. (author), Hoogendoorn, S.P. (author)This paper presents this quick-scan approach for assessing the cost-effectiveness of smaller and not-well demarcated transport measures that can be used as a first-scan while establishing packages to deal with certain transport problems. It adds to the available evaluation literature (see section 2) in relying on a combination of expert opinions...conference paper 2013

Hansen, I.A. (author)The paper discusses the current state of research concerning railway network timetabling and traffic management. Timetable effectiveness is governed by frequency, regularity, accurate running, recovery and layover times, as well as minimal headway, buffer times and waiting times. Analytic (queuing) models and stochastic micro-simulation are...conference paper 2009

Quaglietta, E. (author), Corman, F. (author), Goverde, R.M.P. (author)In the last decade simulation models and optimization environments have been developed that are able to address the complexity of real-time railway dispatching. Nevertheless, actual implementations of these systems in practice are scarce. Essential for implementation of an advanced dispatching system is the trust of traffic controllers into a...conference paper 2013

(author)Dynamic Traffic Management (DTM) aims to improve traffic conditions. DTM usually consists of two steps: first the current traffic is estimated, then appropriate control actions are determined based on that estimate. In order to estimate and control the traffic, a suitable traffic flow model that reproduces the properties of traffic well must be...conference paper 2012
