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

📢 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.

One of my slides from my talk today at the Transport Ireland conference. It shows the volume of public transport infrastructure promised in Dublin over the next 17 years.... I will discuss some of the constraints in realising our ambitions
