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.

Podcast Mobility Innovators: Human-centered design for Smart Public Transport

Technology and New mobility are reshaping urban transportation in cities. Human-centric design is key to the quality of life in cities, putting people at the heart of urban transport planning. All stakeholders, including academia, will play a key role to reshape the future of mobility.

Potential of on-demand services for urban travel (Flex-OV)

On-demand mobility services are promising to revolutionise urban travel, but preliminary studies are showing that they may actually increase the total vehicle miles travelled, thereby worsening road congestion in cities. In this study, we assess the demand for on-demand mobility services in urban areas,using a stated preference survey, to understand the potential impact of introducing on-demand services on the current modal split. The survey was carried out in the Netherlands and offered respondents a choice between bike, car, public transport and on-demand services. 1,063 valid responses are analysed with a multinomial logit and a latent class choice model. By means of the latter, we uncover four distinctive groups of travellers based on the observed choice behaviour. The majority of the sample (55%) are avid cyclists and do not see on-demand mobility as an alternative for making urban trips. Two classes (27% and 9% of the sample) would potentially use on-demand services: the former is fairly timesensitive and would thus use on-demand service if they were sufficiently fast. The latter class however is highly cost-sensitive, and would therefore use on-demand mobility primarily if it is cheap. The fourth class (9%) shows very limited potential for using on-demand services.

The future of public transport in the era of emerging modes

Due to societal and technological trends and developments, new modes (will) emerge. In this workshop at the Urbanism Next Europe conference, Maaike Snelder (TNO/TU Delft), Maria Alonso-Gonzalez (KiM) and Niels van Oort (TUDelft) shared their research findings about on-demand pooled services, autonomous shuttles and share bicycles and discussed about their contribution to the future of public transport.

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.

Workshop Future of Public Transport @Forum ISTS

Due to societal and technological trends, our mobility system and patterns might change. New modes are entering (and leaving) the market, while conventional modes are improved. In this workshop we looked to the future of public transport from the perspective of authorities and operators. The city of The Hague and the Dutch railways (NS) shared their visions on the public transport of the future.

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.

Travellers’ preferences towards existing and emerging means of access/egress transport

This research elaborates on access/egress transport in further detail and aims to provide insights in the preferences of travellers for existing and new means of access/egress transport such as shared vehicles and on-demand ride services. In this research, a stated preference experiment was performed with Dutch train travellers. In addition to the modal preferences, the expected impacts on land use near train station were assessed.
