πŸ“£ New Research just published.

Adoption of EVs, solar PV, and heat pumps in Ireland is driven by affluence. Current grants favour high-income groups, risking a "green divide." Policies must focus on equity and lower upfront costs.

New study of e-cargo bikes:

"Most participants felt more respected by motorists, more secure, more powerful, and more entitled as road users when e-cargo cycling [compared to traditional biking]."

Excellent piece by @briancaulfield.bsky.social

We are fair weather and short term thinkers when it comes to our transport system. It’s failing us all.

Brian Caulfield: Storm Chandra commuter chaos is made far worse by a dysfunctional transport system Aftermath of Storm Chandra has shown once again that in an era of increased extreme weather events, our infrastructure is not fit for purpose

A lessons the past 12 months has taught us about our creaking transport networks is that they are extremely vulnerable. The aftermath of Storm Chandra has shown us, again, that in an era of increased extreme weather events, our infrastructure is not fit for purpose

Contactless payments on public transport 'to take a long time' to complete There had been speculation Dubliners would be waiting until 2029 to get contactless public transport payments.

I joined @newstalkfm.bsky.social Breakfast this morning to discuss the introduction of contactless payments on public transport in Dublin. The city would join the almost 750 cities worldwide that have the same systems

Prof Brian Caulfield: Can anything be done to end M50 gridlock? Motorway is daily inescapable reminder of Dublin’s status as world’s 10th most-congested city

"Continuing to build more roads to alleviate congestion, especially in a geographically constrained city such as Dublin, is precisely the kind of failed thinking that has resulted in our capital becoming the 10th most congested city in the world."

It would be in direct contradiction to our climate laws & obligations, prolong car dependency, and be contrary to the 2022-2042 GDA Transport Strategy, not to mention the biodiversity impacts.

Unfortunately, after decades of underinvestment in the city, another road is not going to fix our problems

M50 congestion can only be fixed through Government policy change, says TII Sean O’Neill says traffic on the motorway have supassed Celtic Tiger numbers

Building the eastern bypass is far from a short or even a medium-term solutionβ€”it would take 15-20 years in planning and construction and cost billions!

A major extension to the Dart network that's to serve new neighbourhoods in west Dublin has been delayed for at least four years.

The move has been described as "contrary to best international practice" by one transport expert.

Delighted to see the Elgar Encyclopedia of Transport and Society published today.

I authored Chapter 56 which defines decarbonisation of transport.

It is great to be listed with my international peers in this encyclopedia.

The transport investment plan is out, it looks to fund all the projects we have come to know over the years.. No new investment in Luas, bar the 4km Luas Finglas line.

If you include the €2bn for Metrolink the PT & Active travel vs Roads ratio is 1.4:1

My 4th year students present projects on decarbonisation of transport at 10am. They have lived experience in how far we have to come: I got a 7:20am email from a student whose 6:53am bus didn't arrive, meaning they won't make it for 10am. Happy World Sustainable Transport Day.
