Podcast: Optimal mix: Light rail vs. Bus Rapid Transit
Join Paul Comfort on this episode of Transit Unplugged for an insightful conversation with Professor Niels van Oort. Paul and Niels explore critical considerations in transit planning, including the effectiveness of light rail versus bus rapid transit (BRT), integration with cycling and micro-mobility, and global best practices for creating high-quality transit systems.
Niels shares details about his innovative transportation planning game designed to help students and professionals balance various mobility modes and societal goals. He also discusses the benefits, challenges, and appropriate contexts for implementing light rail and BRT systems, emphasizing the importance of seamless integration with active transport modes like cycling.

Micromobility+transit integration
Integration between legacy public transport and newer shared micromobility modes remains an area of uncertainty for US and European cities and public transport agencies, who wish to harness technology-enabled transportation modes to complement existing service and expand mobility for residents; with numerous available service and integration models, however, it remains unclear what program design and under what conditions fruitful integrations and partnerships may exist. Europe and the US remain dominant markets for still-emerging micromobility services, and while ample research has considered specific cases, few have examined programs across continents to advance understanding across contexts.
In this joint project of Oregon University (Urbanism Next Centre; Anne Brown) and TU Delft (Smart Public Transport Lab; Niels van Oort), the aim is to answer two research questions:
- What range of strategies have been implemented in Europe and the US to integrate
micromobility and public transport services (e.g., fare integration, free transfers,
collocating parking with stations etc.)? - What are the challenges and opportunities of different integration strategies from both city
and operator perspectives? How do these vary across contexts (e.g., land use, city size,
transit or micromobility mode)?
The collaborative research will use a combination of literature review and interviews with city,
micromobility operator, and public transport staff to document the types of integration strategies
implemented alongside known outcomes/evaluations to date and the challenges, opportunities,
and lessons learned from implementation efforts.
Anne Brown is a visiting researcher at TU Delft in the Smart Public Transport Lab from January
to July 2025. Her research examines transportation equity, shared mobility and technology in
transportation (micromobility, ride-hail, microtransit, public transport), and travel behavior.
Collaborative research at TU Delft will focus on connections between micromobility and public
transport. Read more via https://anne-brown.com/research/

The future of (public) transport
With the team of the TU Delft Mobilisers, we developed 4 future mobility scenarios and presented them on the Dies (Jan, 16, 2025). These scenarios are no predictions or desired future, but a framework to discuss future directions, shaping the future of mobility, and innovation, research and education agendas accordingly. Find the report HERE.
In addition to the general scenario description, the 12 Mobilisers, from 6 faculties, also wrote perspectives on their own domains. Read my perspectives on public transport and shared mobility HERE.

Bicycle and transit integration
10 years of integrated Bicycle+Transit research
One sustainable mode gaining more attraction recently is the bicycle-transit combination: with a bicycle ride before and/or after the public transport journey. Integrating these modes, both short and long distances from door-to-door can be covered fast and comfortable (thanks to transit) and flexible (due to the bike). This makes the bicycle-transit combination a potential competitor for the car. In addition, the effectiveness of public transport will substantially increase due to increased catchment areas and enhanced first and mile options. However, integrating both modes is not easy and knowlegde about planning, behaviour and implementation are limited. We started our research in this domain back in 2015 and then provided many insights since then, provided in classic journal papers, but we also put much effort in other formats, suiting better to all needs.

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.
