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 RafaƂ 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.

COVID-19 and public transportation: current assessment, prospects and research needs

Given the rapid pace of developments and different pathways in different places, Alejandro Tirachini and I decided to synthesize the key developments so far regarding public transportation and the COVID-19 pandemic. We present the different responses adopted by governments and public transportation agencies around the world and their related effects, and identify the research needs pertaining to critical issues that minimize contagion risk in public transportation in the so-called post-lockdown phase.

Avoiding the crowds

What is the crowding level that passengers find acceptable under various infection rate levels of the corona epidemic?

Fresh results from our survey show that train users are divided on this topic. Do you count yourself among the ‘crowd avoiders’ or ‘willing travelers’?

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:

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