OV+Deelfietscombinatie

In de grote steden zien we steeds meer (verschillende) deelfietsen, al dan niet in combinatie met OV. De provincie Zuid-Holland wil graag het gebruik van de deelfiets verder stimuleren. Veel onderzoek richt zich echter op dichtbevolkte (binnen)steden, dus besloot student Rody Boting van het Delftse Smart Public Transport onderzoek te doen naar de mogelijkheden in de regio.

De auto de wijk uit, dat is nog niet zo makkelijk

Wouter van Noort schrijft in NRC over autoluwe straten. Onderzoek laat  de belangrijkste voorwaarden voor succes zien: Goede ruimtelijke inrichting en betrokkenheid van bewoners en gebruikers. Daarnaast is een volwaardig alternatief cruciaal en dat is meer dan een haltepaal op de hoek. In ons onderzoek proberen we te ontrafelen hoe een volwaardig alternatief in de vorm van OV en deelmobiliteit eruit zou moeten zien. Dat begint met de voorkeuren en gedrag van verschillende groepen reizigers om daar vervolgens een passend aanbod op te ontwerpen, incl. hoogwaardig ov, mobiliteitshubs en deelmobiliteit.

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.

Train traveller behaviour during and after Covid: insights of a longitudinal survey of Dutch train passengers

The pandemic had (and still has) an obvious impact on public transport (use). To gain insights into passenger behaviour during and after the pandemic, a longitudinal survey is organised with the goal to capture behaviour, attitudes and intentions related to train usage. Four surveys were held between April and December 2020, involving 23,000-47,000 passengers each. The results provide valuable, quantitative insights that help to recover and rethink public transport after the pandemic, for instance by adjusted planning, design and operations. Findings show that 30% of the passengers want to avoid the peak hour after Covid and 72% will telework more often, saving multiple trips per week. The most popular days for teleworking will be Friday and Wednesday. Related future research directions are for instance developing more flexible and demand-driven schedules and services.

How do Dutch train passengers (expect to) travel during and after Covid?

Thursday 5th November, the ETC Programme Committees for Local Public Transport and Rail Policy and Planning hosted a Covid webinar on: “How do Dutch train passengers (expect to) travel during and after Covid? Insights from a longitudinal panel of over 20,000 train passengers”, by Mark van Hagen (Netherlands Railways) and Niels van Oort (TU Delft). Together, Mark and Niels initiated a longitudinal survey amongst Dutch train travellers and how they cope with Covid with regard to their (future) travel patterns. In this webinar, they will share the main findings and lessons. A reflection from a wider EU perspective will also be given by András Munkácsy, Head of the Department for Transport Management at the KTI Institute for Transport Sciences, Hungary.
