Here we revisit the issue of urban parking (in Freiburg, Germany). Fines are low enough in relation to control densities that it makes economic sense to not pay parking fees. Cities need to rethink parking. Free copies: doi.org/10.1016/j.tran…

What is the cost of driving a car over a lifetime? Considerable - for car owners - and significant for everybody else: doi.org/10.1016/j.ecol…

This was the earliest comment on tourism and COVID, now downloaded >300,000 times, and (probably) the most read tourism paper ever: doi.org/10.1080/096695…. For those still caring/coping, here is a 'two-years of' follow-up: doi.org/10.1080/096695…

Is there a good way of illustrating the energy-intensity of air transport? Here an attempt involving the local hardware store...

To convince more people to cycle, infrastructure needs to be subjectively safe, i.e. from the perspective of those cycling. The only way to really achieve this? A network of car-free streets: doi.org/10.1016/j.jtra…

Who is a roadblock to traffic safety legislation? Drivers of large cars deliberately violating traffic laws and opposing stricter legislation. Who also happen to be the voters for conservative and liberal parties... Free downloads: doi.org/10.1016/j.trf.…

If you work with transport system change, this is the one of my papers I would want you to read: doi.org/10.1080/174501…

2022 has been a year of weather extremes. Can we expect people to give up on the most carbon-intense activity, flying? Unfortunately, this review is not hopeful: wires.onlinelibrary.wiley.com/doi/10.1002/wc…

With nothing much happening at COP27, here is the blueprint for net-zero tourism, published today, free downloads: doi.org/10.1016/j.tour…

In this paper we show that a) continued growth in air traffic demand makes it unlikely that net-zero goals will be met; b) CO2 cost internalization is necessary: c) climate AND industry will profit from a new business model: doi.org/10.1016/j.jair…

Today, DW reports on the carbon footprints of the very wealthy: dw.com/en/rich-people…, a timely coincidence: doi.org/10.1016/j.clpl…: We show that millionaire growth alone will deplete 2/3 of the remaining carbon budget to 1.5°C. The conclusion is yours.

License renewal tests are politically taboo in Germany, even though older drivers cause many collisions and injuries. This paper shows that a majority of older drivers supports tests and is open to autonomous mobility services (when available): doi.org/10.1016/j.trip…

Germany is basically the only country in the world without a speed limit. We wondered: is this economically justified, for example to save travel time? Read the results here: The economic cost of a 130 kph speed limit in Germany. doi.org/10.1016/j.ecol…
