Denne artikel omhandler resultaterne af showcases i EUFAL (Electric Urban Freight and Logistics) projektet, som er kørt i perioden 2017-2020. Projektet har til formål at skabe en udvekslingsplatform for virksomheder, der har et ønske om at integrere elektriske køretøjer i deres flåder af erhvervskøretøjer. Showcases er udført i samarbejde med danske virksomheder, der har implementeret elektriske køretøjer i deres flåder for at teste, om en sådan løsning kan opfylde en række specifikke krav inden for den kommercielle sektor. Virksomhederne udfører alle opgaver af forskellig type inden for det Storkøbenhavnske område, og som en del af projektet har virksomhederne fysisk erstattet nogle af deres konventionelle køretøjer med elektriske køretøjer i en testperiode på et år. Data er løbende indsamlet og behandlet i løbet af foråret og sommeren 2020 og resultaterne af projektet vil blive præsenteret ved Trafikdage 2020., Proceedings from the Annual Transport Conference at Aalborg University, Vol. 27 No. 1 (2020): Proceedings from the Annual Transport Conference at Aalborg University

First International Symposium on Flutter and its Application (May 15-17, 2016. Mielparque-tokyo), Minato-ku, Tokyo, Japan, Inclusion of a horizontal degree of freedom along with the vertical and twisting degrees of freedom has been an active area of research in bridge flutter predictions for the past three decades. While much work has been published on theoretical aspects, limited experience as to the importance of the horizontal degree of freedom is available in the literature. Three cases of actual long span bridge designs are examined with respect to the critical wind speed for onset of classical flutter. For the tree cases examined inclusion of the horizontal modes of motion had almost negligible influence on the flutter wind speed., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1630046023, レポート番号: JAXA-SP-16-008E

Designing a public transport timetable that maximizes passenger service, measured in weighted travel time, is an intricate problem. The weighted travel time depends on the free route choice of passengers. Passenger route choice depends on the timetable. In turn, the timetable that minimizes weighted travel time depends on the route choice of passengers – and therefore requires passenger route choice information. Consequently, a sequential approach where timetables are designed provided pre-fixed passenger assignment to routes, may not find the optimal timetable. This paper aims to integrate passenger route choice and timetabling. It addresses the problem of designing maximal passenger service public transport timetables in systems with free route choice within a budget for operating costs. Operating costs are defined by the minimal cost vehicle schedule required to operate the timetable. The proposed methodology integrates a matheuristic for timetabling and vehicle scheduling with a passenger assignment model in an iterative framework, where different forms of integration are evaluated. Focus is on long to medium term timetabling, provided an initial timetable. Results for a realistic case study in the Greater Copenhagen area indicate that our approach consistently leads, at no additional cost, to timetables that represent a reduction in passenger weighted travel time in comparison to both an initial timetable and anon-integrated timetabling method that receives a single passenger assignment as input.
