Combating congestion is a worldwide problem. However the declare “extra automotive sharing, much less visitors” has come underneath scrutiny these days. 2025AD talked to Tilman Santarius, a sustainable digitalization knowledgeable.

2025AD: Professor Santarius, your analysis covers digitalization and sustainability. What’s the main target of your work?
Tilman Santarius: Our society has been struggling to grow to be extra sustainable for many years: to forestall local weather change, but additionally to cease soil loss, protect biodiversity and enhance air high quality in cities. On the identical time, the digitalization of society has been a megatrend for years, more and more impacting the financial system, schooling, commerce and the transformation of our power provide. The large query is: can we leverage this megatrend to assist us attain our targets quicker?
2025AD: What function does mobility play in that regard?
Santarius: Within the mobility sector, I see enormous alternatives and dangers of digitalization alike. It affords the prospect to higher set up visitors flows and persuade individuals to change from motorized particular person types of transport to public and shared technique of transport. With the assistance of digitalization, it might grow to be faster, extra snug, doubtlessly cheaper and even sexier to make use of such types of transport. However on the identical time, if everybody owns a self-driving automotive sooner or later, it might severely worsen our issues. Many individuals haven’t acknowledged but how knowledge intensive and thus power hungry these autos shall be. Every automotive generates about 4000 gigabytes a day. This might finally flip into an ecological nightmare.
2025AD: Within the public debate, the information starvation of driverless vehicles hasn’t been a lot of a problem to date.
Santarius: The subject is massively underestimated. Everyone is demanding higher and quicker knowledge connections. Driverless vehicles are actually one of many most important causes behind the German authorities’s push for a 5G customary. However I get the sensation nobody has considered sustainability to date. What sort of driverless autos are fascinating? Privately owned vehicles? Shared robocabs? Autonomous vans for logistical functions? It stays unclear. I do know one factor: if all 45 million passenger vehicles in Germany grow to be autonomous, then the 5G community will most definitely be overloaded. Based on my estimates, 1.5 million autonomous autos would generate the identical quantity of information as half of the world inhabitants at present on-line.
2025AD: Mobility as a service appears to be all the craze proper now, whether or not it’s automotive sharing, ride-hailing or ride-pooling. Why is such a variety of recent affords popping up now?
Santarius: Buyers see one of many largest future markets. The mobility market has at all times been very worthwhile. Individuals have to get from A to B and incessantly make use of companies to take action. What makes the market much more promising is the prospect of producing knowledge like movement profiles or consumer preferences that may be monetized in different methods. That is the explanation why Google and different non-automotive gamers are coming into these markets, too.

2025AD: All these new sharing companies promise to sort out city congestion, cut back the variety of autos on our roads and save emissions. Is that credible?
Santarius: Basically, I discover the sharing method very cheap. However I like to tell apart between good and dangerous sharing. Admittedly, it isn’t straightforward to attract the road. For a number of years now, we now have seen companies that don’t make a optimistic contribution relating to sustainability. The instance of how Uber has actually increased traffic has already been closely mentioned. The town of San Francisco, the place Uber is especially profitable, claims that Uber rides have harm the occupancy charge of the BART, the town’s prepare system. And that isn’t fascinating in any respect. It’s nice if individuals use shared mobility. However public transportation nonetheless has the most effective carbon footprint. If individuals use these companies as a substitute of public mass transit, it can forestall an ecological transformation of our visitors system.
2025AD: In Germany, free floating automotive sharing companies like Car2Go or Drive Now are more and more common. Are they a extra sustainable possibility?
Santarius: These approaches may very well be a part of a viable visitors system – however provided that they don’t compete with public transit and seduce prospects to make use of vehicles after they in any other case wouldn’t have completed. We’d like smarter integration right into a municipal transport system.
2025AD: So is it as much as communities to get it proper?
Santarius: They should align these companies with public transit. Shared mobility affords needs to be dominant the place public transit has gaps or is uncomfortable. They might clear up the well-known final mile downside for instance. On the identical time, communities have to make proudly owning a personal automotive much less engaging: by lowering parking house, growing parking charges or increasing pedestrianized areas. We’d like a mixture of incentives and disincentives to create a sustainable visitors system.

2025AD: What might such a symbiosis between public transport and personal companies appear like?
Santarius: First, communities might want to set sure circumstances when licensing automotive sharing suppliers. Their algorithms ought to concentrate on serving routes that aren’t coated by public transit. Second, communities have to allow customers to e-book a multimodal transport chain on the go. Say I plan to make use of ride-pooling to get to the station, then a prepare and afterwards a shared bike to succeed in my remaining vacation spot – I’d wish to e-book all that in a single process. It have to be straightforward and cozy for the consumer.
2025AD: It appears many gamers are already engaged on options like that.
Santarius: In fact, a number of entities are engaged on it, additionally scientists. However progress is remarkably gradual. A part of the issue is that everyone needs to stay secretive. Deutsche Bahn has no real interest in the truth that car-sharing suppliers promote rail tickets on their car-sharing apps or vice versa. I hope we’ll see some motion right here quickly.
2025AD: May autonomous driving assist cut back supply visitors in cities?
Santarius: I haven’t made up my thoughts but. My concern can be that it might improve logistics visitors as a result of it optimizes prices by eradicating the motive force. And something that optimizes prices normally results in larger demand. I discover that problematic. However I see excessive potential for digitalization to enhance freight administration. As we speak, virtually half of all truck journeys are unladen. A laden truck drives from Munich to Hamburg and returns empty whereas on the identical time a laden truck leaves Hamburg to drive to Munich. We are able to do higher than that.
2025AD: Do you see different cheap use circumstances for autonomous driving?
Santarius: Sure, take on-demand busses or cabs in rural areas as an illustration. They’re usually not economically possible immediately as a result of they aren’t occupied constantly. It is sensible to deploy autonomous autos for such circumstances. It gained’t destroy jobs however improve mobility.
