Uber both competes with, and complements public transport

Between 1 and 2 out of 5 Uber trips have no viable public transport alternative. At the same time, in 15 percent of the cases in Amsterdam, public transport would actually have been faster than Uber. Check out this TU Delft news article, where we share our key results based on data from 3.5 million trips in 6 cities in the US and Europe.

Modelling virus spreading in ride-pooling networks

Will a random infected passenger spread a virus across a large number of travellers using ride-pooling services? or will it be encapsulated and thus confined to a distinct community? How many other travellers will get infected and how will the epidemiological process evolve? Finally, can we mitigate it by effective control and design measures and thus introduce it to policymakers as a safe alternative?

See our open-access work published in Scientific Reports with Rafał Kucharski and Julian Sienkiewicz.

We combine epidemiological and behavioural shareability models to examine spreading among ride-pooling travellers, with an application for Amsterdam. 

Findings are at first sight devastating, with only few initially infected travellers needed to spread the virus to hundreds of ride-pooling users. Notwithstanding, we identify an effective control measure allowing to halt the spreading before the outbreaks without sacrificing the efficiency achieved by pooling.

Demand for Urban Pooled On-Demand Services

María Alonso González of our Smart Public Transport Lab has been awarded the 2nd prize of the European TRAVISIONS 2020 young researcher competition (cross modality category). Congrats Maria, well deserved!

This recognition of Maria’s excellent work joins the Michael Beesley Award for the best
young researcher paper at the Thredbo 16 international conference in Singapore. Her research has also been shortlisted among the top 12 submissions for the
2020 ITF (International Transport Forum) Young Researcher of the Year Award.

Interested in learning about Maria’s work? You can find here the her PhD dissertation entitled “Demand for Urban Pooled On-Demand Services: Attitudes, Preferences and Usage” which she defended in July.

The following journal publications are included in her PhD dissertation:

In addition, she contributed to more than 10 conference proceedings and numerous national and international events where she shared her research findings with experts, service planners and providers and other partners in the industry.

This work took place as part of the SCRIPTSproject financed by NWO which is a forerunner of the ERC project CriticalMaaS.

The role of mobility in spreading COVID-19

At the Smart Public Transport Lab we are currently undertaking a series of studies related to the corona crisis. Given the urgency and the gravity of what is at stake, we share results as soon as we are confident that we can contribute to the policy and scientific debate with sound models and empirical findings.

By now we are ready to share findings from two studies focusing on the role of mass transit and ride-sharing in spreading the virus. Welcome to check out our short articles following these links:
Virus spreading in public transport networks: the alarming consequences of the business as usual scenario [A slightly modified version is available on ResearchGate]

When sharing is not always caring: On the spreading processes in ride-sharing networks [A slightly modified version is available on ResearchGate]

And stay tuned for upcoming results from on-going studies.

Can ride-hailing replace all public transport services?

Presented last week some of our research activities together with AMS on the WeMakeTheCity festival in Amsterdam in a session devoted to the future of MaaS and PT. While I do not argue that we should replace all public transport with individual on-demand services, I think that it helps to illuminate the ramifications of hypothetically doing so and hence support the debate with research findings.
