The NTA Household travel survey results for 2024 are out...

Mode share for driving is up and now higher than it was in 2012.

Cycling mode share has increased slightly on 2023

% of our trips to work are down 7% on 2017, the impacts of WFH & COVID

A very sensible idea, one that is done in many other cities...

FYI the Metrolink railway order will be with An Coimisiún Pleanála 3 years tomorrow....

Planned Dublin Metro linking city centre with airport and Swords could open in stages

Testing and starting services on railway in phases could cut multi-billion euro project’s costs

Fantastic op ed by Paul Farrell in the Sunday Independent today. Hammering home the point of the importance of investing in our universities

@tcddublin.bsky.social

m.independent.ie/opinion/paul...

Paul Farrell: It’s delusional to think universities will thrive without extra funding

“The value of an idea lies in the using of it,” said Thomas Edison, whose many credited inventions include the commercially viable light bulb. It remains as true today as it did a century ago.

Ireland’s mild weather isn’t a shield - @tcddublin.bsky.social Professor Karen Wiltshire and Associate Professor Graham J. Dwyer explain in @theconversation.com why climate risk is real and growing. Insightful and urgent reading.
