CO2 Barometer
In this PhD project by Marko Kapetanović, an integrated model for dynamic monitoring and prediction of CO2 emissions of regional railway services is developed, following a life-cycle approach. The project is performed in close cooperation with Arriva, the largest regional railway undertaking in the Netherlands. Possibilities and measures to improve the energy efficiency of railway operation and to reduce the total emissions on the network are identified and assessed, including alternative propulsion systems such as hybrid, plug-in hybrid, fuel cell-electric and battery electric, together with a range of energy carriers. Analyzed fuels and energy carriers include LNG, first and second generation biofuels, hydrogen and electricity, with examined various alternative production pathways. Check the main output of this project below.

Impacts of Covid on train traveller behaviour / De gevolgen van de coronacrisis op treinreisgedrag
Delft University of Technology and the Dutch railways (NS) started a joint, longitudinal research in April 2020 on Covid impacts on train passenger behaviour. During and after the pandemic, 8 surveys in different stages (15,000-45,000 participants each) were held to learn about the impacts and expectations.

TU Delft en NS zijn 24 april 2020 een grootschalig, longitudinaal onderzoek naar de gevolgen van de coronacrisis op het reisgedrag gestart. In de 8 metingen zijn per keer 15.000-45.000 reizigers bevraagd. Door de intelligente lockdown daalde het aantal treinreizigers in 2020 tot ongeveer 7% ten opzichte van normaal. De onderzoeksvraag is hoe reizigers zich tijdens en na de crisis (verwachten te) gaan gedragen. Vanuit NS zijn Valerie Severens, Menno de Bruyn en Mark van Hagen betrokken bij dit onderzoek. Bij de TU Delft zijn dat Danique Ton, Dorine Duives en Niels van Oort.

PhD project: Robust train trajectory optimization
In cooperation with the Dutch Railways (NS), Alex Cunillera works in this PhD research on robust train trajectory optimization. Even two trains of the same model running on the same line show significant differences in their dynamics. This might be due to different passenger loads, weather, fault history, driving style of the train driver, etc. Moreover, there are uncertainties in the track data that may also have a strong influence on the train operation. This research focuses on determining the uncertainties and stochastics of these variations and developing methods to compute robust train trajectories that optimize the energy consumption and minimize delays in the presence of the mentioned variations.

Inclusief openbaar vervoer, van theorie naar praktijk
Hoewel de theorieën over rechtvaardige mobiliteit niet nieuw zijn, missen we nog wel kennis over de implicaties en toepassing. Monica van Luven van het Smart Public Transport Lab deed bij de Vervoerregio Amsterdam onderzoek. “We staan nog aan het begin van goede inbedding van inclusieve mobiliteit in onze beleidscyclus en moeten nog verschillende belangrijke keuzes maken.”

Covid impacts on train travel behaviour
Delft University of Technology and the Dutch railways (NS) started a joint, longitudinal research in April 2020 on Covid impacts on train passenger behaviour. During the pandemic, 7 surveys in different stages (15,000-45,000 participants each) were held to learn about the impacts and expectations. The main results are presented in an infographic.

Micromobility and public transport
Following technological and societal developments, new modes and services arrive in our cities. Micromobility solutions, such as shared (e-)bikes and –scooters, are adding new opportunities for individuals, but what their (potential) contribution is to societal objectives such as sustainability, land use and inclusiveness, is not yet known. In order to gain this knowledge and optimize the mobility mix, the Smart Public Transport Lab investigates the demand and supply impacts and interaction of micromobility, including the interaction with public transport. In this infographic the main, recent results of the ongoing research are summarized.

The future of public transport
Every year in the advanced public transport course, students write an essay on the future of public transport. Passenger association ROVER selects the best one according to the passengers’ perspective. The authors of the winning essay are invited to record a podcast with Geert Kloppenburg in his Metroplitan Podcast series.
