- Joint Oireachtas Committee on Transport, Tourism and Sport: Bus Coach Sector: Discussion (19 Oct 2022)
Kieran O'Donnell: I am familiar with that. My local authority in Limerick was exceptional in fast-tracking such cases but even then, they took time. Will our guests come up with an effective protocol based on what is happening elsewhere? If it is too complicated, it will not happen. I ask them to give timescales and come back with something with which we can approach the NTA. We would certainly like it to...
- Joint Oireachtas Committee on Transport, Tourism and Sport: Bus Coach Sector: Discussion (19 Oct 2022)
Kieran O'Donnell: I thank Mr. Conway, Mr. Crowley and Mr. Lynch for coming before us. We ask them to write to us on those matters. We see our committee very much as one that is looking to get solutions and being proactive. We are in the process of writing to the RSA and we held off on that until our guests had appeared before us because we felt that elements of this meeting would cover its sector as well....
- Joint Oireachtas Committee on Transport, Tourism and Sport: Bus Coach Sector: Discussion (19 Oct 2022)
Kieran O'Donnell: The purpose of this session is to discuss TII's report, Impact of National Road Speed Limit Reductions on Greenhouse Gas Emissions. I welcome Mr. Derek Brady, head of strategic and transport planning, and Ms Helen Hughes, director of professional services, TII. I thank the witnesses for their forbearance as the other session ran over; nonetheless it will be just as illuminating. I will...
- Joint Oireachtas Committee on Transport, Tourism and Sport: Bus Coach Sector: Discussion (19 Oct 2022)
Kieran O'Donnell: I am sorry; what will that analysis entail?
- Joint Oireachtas Committee on Transport, Tourism and Sport: Bus Coach Sector: Discussion (19 Oct 2022)
Kieran O'Donnell: Is Mr. Brady talking then about a kind of hierarchy in terms of speed limits going from motorways to national and regional roads?
- Joint Oireachtas Committee on Transport, Tourism and Sport: Bus Coach Sector: Discussion (19 Oct 2022)
Kieran O'Donnell: TII's report is saying in layman's terms that reducing the speed on motorways drives people onto the national roads and reducing the speed on national roads drives people onto the regional roads.
- Joint Oireachtas Committee on Transport, Tourism and Sport: Bus Coach Sector: Discussion (19 Oct 2022)
Kieran O'Donnell: Did TII factor reducing the speeds and cascading down along into that?
- Joint Oireachtas Committee on Transport, Tourism and Sport: Bus Coach Sector: Discussion (19 Oct 2022)
Kieran O'Donnell: Did TII not look at speed limits below that tier?.
- Joint Oireachtas Committee on Transport, Tourism and Sport: Bus Coach Sector: Discussion (19 Oct 2022)
Kieran O'Donnell: Has TII been able to measure the greenhouse gas emissions on the various forms of roads in Ireland, for instance, what percentage comes from motorways, national roads and regional roads? Does TII have that kind of empirical work done?
- Joint Oireachtas Committee on Transport, Tourism and Sport: Bus Coach Sector: Discussion (19 Oct 2022)
Kieran O'Donnell: That would obviously be a big factor as well.
- Joint Oireachtas Committee on Transport, Tourism and Sport: Bus Coach Sector: Discussion (19 Oct 2022)
Kieran O'Donnell: Is there a direct correlation from that figure to the greenhouse gas emissions generated by both or does a much higher percentage come from motorways?
- Joint Oireachtas Committee on Transport, Tourism and Sport: Bus Coach Sector: Discussion (19 Oct 2022)
Kieran O'Donnell: I will keep going. Appendix A of the report makes for very interesting reading. For the ordinary layperson out there, when we look at the different types of cars, we see that a small petrol car is most efficient when it is doing approximately 60 km/h. A medium-sized petrol car is best when it is doing approximately 70 km/h. A large petrol car, interestingly, is better when it is doing 80...
- Joint Oireachtas Committee on Transport, Tourism and Sport: Bus Coach Sector: Discussion (19 Oct 2022)
Kieran O'Donnell: They are at 50 km/h. Then the small HGVs are better at 50 km/h. It is very interesting that when one goes down into the lower range, in many cases they are all very highly inefficient. With emissions, if traffic is free-flowing it is fine in many cases when travelling at low kilometres per hour. For example, a small petrol car is far more inefficient doing 20 km/h than 110 km/h, which is...

Kieran O'Donnell: If we consider the small petrol car, which many people would have, it is far more inefficient when travelling below 50 km/h. It is the same at 50 km/h, but it is highly inefficient at 30 km/h. It is very inefficient at 20 km/h, and it is highly inefficient altogether at 10 km/h. It is best at 60 km/h. Going back to the question, the model is really built around getting free-flowing...
- Joint Oireachtas Committee on Transport, Tourism and Sport: Bus Coach Sector: Discussion (19 Oct 2022)
Kieran O'Donnell: On average, cars are at their most efficient when travelling at between 50 km/h, 60 km/h and 70 km/h. Is that correct?
- Joint Oireachtas Committee on Transport, Tourism and Sport: Bus Coach Sector: Discussion (19 Oct 2022)
Kieran O'Donnell: They are very good at 50 km/h. They are very good around urban driving and are very suitable for that.
- Joint Oireachtas Committee on Transport, Tourism and Sport: Bus Coach Sector: Discussion (19 Oct 2022)
Kieran O'Donnell: At 110 km/h, a small electric vehicle is not quite as bad as a small petrol car, but it is getting there. It is still better than a diesel combustion car or a petrol combustion car on the motorway. Am I right?
- Joint Oireachtas Committee on Transport, Tourism and Sport: Bus Coach Sector: Discussion (19 Oct 2022)
Kieran O'Donnell: Can Mr. Brady explain to me, as an ordinary person, why those greenhouse gas emissions are higher than one would expect at the higher speeds?
- Joint Oireachtas Committee on Transport, Tourism and Sport: Bus Coach Sector: Discussion (19 Oct 2022)
Kieran O'Donnell: I am talking about PHEVs. What are they?
- Joint Oireachtas Committee on Transport, Tourism and Sport: Bus Coach Sector: Discussion (19 Oct 2022)
Kieran O'Donnell: So, they are still hybrids.
