What is the value of integrating bike sharing systems and public transport?
From abroad, people often look enviously at the success of the Dutch integration of cycling and public transport, where the best of both worlds come together. Not only for the first miles to the station, but also for the final part of the journey, thanks to the availability of shared bikes. Watetu Mbugua, who came from Kenya to study in Delft, was surprised at how relatively little people knew about this success. That’s why she conducted research in the Smart Public Transport Lab into the societal costs and benefits of this combination, using the “OV-fiets” (public transport bike operated by the Dutch Railways (NS)) as a case study.
By: Niels van Oort (Article translated from Dutch, see OV Magazine)
“The research started with an extensive search in international literature on all the aspects that contribute to the (societal) costs and benefits,” says the Kenyan. “Based on the 14 most important factors, I then looked for data to quantify the effects of OV-fiets for the past 20 years and monetize them. It was a painstaking task, but I’m proud that I succeeded.”
Mirjam Borsboom from the cycling policy team of the Ministry of Infrastructure and Water Management confirms the international interest. “On average, the Netherlands receives more than four (!) requests per day from around the world, asking about cycling. Especially about cycling infrastructure, culture, and incentive projects. In large cities, the bike+public transport combination is particularly popular, leading to many questions, for example, about bike parking at public transport stations.”
Mbugua found that the benefits regarding accessibility were especially large, followed by congestion reduction and health benefits. On average, the benefits were 50% higher than the costs, such as investment and operational expenses. To avoid overly optimistic results, she worked with ranges and sensitivity analyses. “In every scenario, we actually see that the benefits outweigh the costs, even when very conservative assumptions are applied, such as the shift from car to bike+public transport.” In some cases, the benefits were as much as 2.5 times higher than the costs, making it a clearly socially responsible investment. “In the Netherlands, cycling is already very common, so the potential in other countries could be even greater,” Mbugua expects.
That is also where Borsboom sees the main value of this study: “Not only to further apply and improve the Dutch bike+public transport system but also to assist other countries in setting up similar systems.” As far as Mbugua is concerned, the Netherlands should be more proud of its existing bicycle+public transport system. She sees room for improvement particularly in high-quality bus and light rail connections, where shared bikes play only a minor role. “The potential to apply this success abroad is huge, but attention to road safety is crucial. Unfortunately, in many parts of the world, cycling often comes with high risks due to a lack of safe infrastructure,” she concludes.

Mobility hubs: Why, who, how?
Mobility hubs are often presented as the solution for enhanced accessibility, a shift towards sustainable mobility and/or improved public space. Sometimes, they seem to be a goal in itself.
In our research, we try to find out how to achieve the mobility, spatial and societal goals by investigating the potential users and their needs, and the required offered modes and facilities accordingly.
The highlights of multiple research projects are presented the infographic below. More details and extra insights are available via the related research papers.

Onderzoeksagenda / Research agenda
In het openbaar vervoer is nog maar weinig bij het oude. Ontwikkelingen als elektrificatie, automatisering en deelmobiliteit hebben hun impact op vraag én
aanbod. Behalve vlot en veilig moet het ov ook groen en inclusief zijn. En dan is er de nog altijd voelbare impact van covid-19. Om op dit speelveld de juiste keuzes te maken, heeft het ov nieuwe inzichten en nieuwe tools nodig. Zie hiervoor mijn (geactualiseerde) Onderzoeksagenda.
The world of public transport is changing rapidly. Developments such as electrification, automation, and shared mobility have had an impact on both demand and supply. Besides being smooth and safe, public transport must now also be green and inclusive. And then there is the still tangible impact of Covid‑19. To make the right choices in this evolving landscape, we need new knowledge and new tools. Find my (updated) Research Agenda.
MT-ITS conference: Identifying potential use of emerging neighbourhood mobility hubs using behavioural modelling
Neighbourhood mobility hubs may play an important role in mitigating the impact of passenger cars on climate change and urban public space. As a relatively new concept, academic research on the user potential of neighbourhood mobility hubs is so far limited. This research aims to identify which user groups are likely to adopt services offered by a neighbourhood mobility hub. A survey was distributed in the Netherlands (N=298) and an Exploratory Factor Analysis (EFA) and a Latent Class Cluster Analysis (LCCA) were executed. Four distinctive groups of intended users were uncovered. Two of the clusters have intentions to use neighbourhood mobility hubs. The other two identified clusters do not (yet) intend to use neighbourhood mobility hubs. The clusters indicate that people who currently already travel more by sustainable modes (train or (e-)bicycle) are more likely to be adopters of neighbourhood mobility hubs than the traditional car users. In practice, this may make the positive effect of hubs more limited than anticipated or even increase car use. However it could also facilitate those travelling sustainable to do so for longer as additional shared modes become available to them via hubs. Limitations and directions for further research are discussed.

10 dimensions of transport related social exclusion
Transport Related Social Exclusion (TRSE) looks at how people who are socially disadvantaged for reasons such as employment status, income, age, or ability, can face limitations in their ability to access transportation services. As income is only one of these factors, people can experience TRSE without having a low income (Yigitcanlar et al., 2018). Rather, social exclusion is defined by an exclusion from economic life, social services, civic life, and social networks (Spoor, 2013). TRSE looks at how elements of the transportation system contribute to this exclusion (Yigitcanlar et al., 2018).
This figure provides an overview of 10 dimensions of Transport Related Social Exclusion, further explained (incl. references) in the position paper of Bruno and Van Oort (2023).

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.
