In order to meet emission targets for 2050 in Europe transport needs to be executed more 2 efficiently. A promising way to make transport more efficient is synchromodal transport. When the 3 service provider has more flexibility to arrange transport, the utilization and use of intermodal transport, 4 such as rail, can be increased and emissions...

Demand exceeding the capacity of a bottleneck will create congestion upstream of that bottleneck. Once this congestion occurs, the maximum flow through this bottleneck decreases (capacity drop). By limiting the flow towards the bottleneck, one can prevent or postpone the capacity drop and the accompanying congestion. In case the bottleneck is...

The Macroscopic Fundamental Diagram (MFD) describes the relation between accumulation and speed in a zone. While theoretically expected, empirical validations have been done with limited numbers of floating car (e.g., taxi) data, and loop detectors. This paper will verify existence, shape and crispness of the MFD using Floating Car Data ...

Floating surface screens could offer an attractive method for
sediment management in the numerous side channels of the Dutch
Room-for-the-River programme. The screens would remove
undesired sedimentation or mitigate bank erosion without the heavy
machinery that might disrupt the local ecosystem.

This study compares a hybrid-electric aircraft featuring a propulsive empennage and over-the- wing, distributed-propulsion to a conventional regional turboprop. The impact of multiple design parameters, mission requirements, and technology assumptions on maximum take-off mass and payload-range energy efficiency is evaluated, in order to...

A numerical investigation on jet-installation noise is performed using a software based on the Lattice-Boltzmann Method. A flat plate is placed in the irrotational hydrodynamic field of the jet, i.e. outside of the plume, resulting in noise increase due to the scattering of instability waves at the plate trailing edge. The configuration adopted...

Airborne wind energy is an emerging technology that uses tethered unmanned aerial vehicles for harvesting wind energy at altitudes higher than conventional towered wind turbines. To make the technology competitive to other renewable energy technologies an automatic control system is required that allows autonomously operating the system...

Container port competitiveness is generally conceptualized as being driven by straightforward criteria, such as port costs, handling efficiency, hinterland connectivity, and the quality of infrastructure and services. Synchromodal freight transport service is an emerging and developing concept of freight transport operations, as shippers and...

The addition of epoxy modifier in bitumen is a relatively new modification technology (1-4) and the most critical epoxy polymerization-induced changes of the epoxy-bituminous materials are not fully understood. Different phenomena take place when epoxy modifiers are incorporated into bitumen and they are dependent on the material hardening...

The utilization of synthetic fibers has been reported in the past (1-8) showing enhancement of fatigue and thermal cracking resistance in asphaltic materials. However, the limited evidences about the benefits of these fibres in asphaltic materials at low material scales have been noticed. Also, the exact reinforcing mechanism of binding system...

The tolerance to the cumulative effects of ionizing radiation is one of the most important parameters to keep into account when selecting an EEE component for space applications. TID sensitivity is normally investigated measuring changes induced by gamma rays from 60Co sources to nominal parameters of a component or to its expected functional...

Steel-concrete composite beams are widely used in practice because of the simple construction sequence and the economic cross-section design. The application of welded headed studs in composite beams prevents the non-destructive separation of the composite beam, which leads to a very low scoring in the sustainability assessment in terms of the...

Truck platooning is a form of vehicle automation and cooperation that is leading the way for cooperative and automated vehicle implementation. However, much is still unknown about the effects and potential dangers of many situations in regard to cooperative control of these platoons. In this contribution, we discuss many of the challenges in...

De steden in Nederland groeien, zowel qua aantallen inwoners als wat betreft economische activiteiten. Dat levert veel mobiliteit op en de daarmee gepaard gaande problemen op het gebied van bereikbaarheid, leefbaarheid en verkeersveiligheid. Om deze stedelijke problemen aan te pakken worden allerlei verkeersmanagementmaatregelen genomen. Maar...

Tourformatie is kenmerkend aan goederenwegvervoer, niet zelden worden meerdere zendingen in een rit vervoerd. Toch wordt dit aspect vaak over het hoofd gezien in goederenvervoermodellen. Wanneer tourformatie wel wordt toegepast, dan worden vaak geen zendingen gemodelleerd, is het modelgedrag niet gebaseerd op empirische data, of wordt slechts...
