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.

At a meeting on Friday I was reminded of how much work we need to do in Ireland to modernise and upgrade our existing rail network. Looking at the statistics, you can see how much work we need to do to even get to the EU average of approx. 57%.

Great to chat on Ireland AM this morning on issues around poor rural public transport. I got to discuss our @researchireland.ie funded @conundrumsfi.bsky.social project and how our research is looking into new ways of solving these issues

Once more for those in the back - Metrolink is not only an airport line
It serves 15 other stations, connecting 127 schools, 3 universities, 5 hospitals, and making over 175k people and 250k jobs accessible by foot to a stop. An estimated 18% of passengers will use airport stop

77% of NDP review submissions prioritised transport investment (low response rate)
Metrolink's €2bn funding & support will see the project start construction, pending planning permission
But the devil is in the detail, how will the rest of the €20bn be spent ..roads vs pt?

📢 New research on e-cargo bike parking in Ireland. We make several observations on cycle parking planning that could help to advance more e-cargo-bike-inclusive cycle parking futures. Thank you to @seai-ie.bsky.social for funding the work.

New results from the @epaireland.bsky.social show our transport emissions are down 1.2%, given we have missed the target for a number of years now we are very far behind the 2030 target.. The report says EV sales have very little to do with he drop due to the low number

The @ccacireland.bsky.social have launched their 2025 transport review. I strongly support the call, and have for a long time, changes to EV grants and to pivot them to a just transition tool. Nice see 5 of my research outputs cited.
