A report has shown an increase in the number of people using sustainable modes of transport to commute into Dublin city.

The joint report from Dublin City Council and the National Transport Authority (NTA) also showed a 10% increase in the number of cyclists commuting in the past year.

Speaking on Newstalk Breakfast, Green Party Councillor Ciaran Cuffe is now calling for increased investment in cycling infrastructure.

"It's one of the most efficient ways of getting from A to B," he said. "Space is getting much tighter in Dublin city, and it simply doesn't make sense anymore to give lots of space to people driving a tonne and a half of metal."

Councillor Cuffe called for investment across the entire system, including for buses and walkways. However, he acknowledged the expense involved, calling the development of the Liffey cycle-way, the Grand Canal cycle-way and the Royal Canal cycle-way "big bucks items".

However, Newstalk's George Hook argued that pedestrians are at risk on a daily basis because of "fanatical cyclists".

"Councillor Cuffe has no interest in pedestrians," he said.

"It's time to make our cities walkable, bikable and livable" 

Councillor Cuffe countered this argument, saying that the only way to make footpaths safe was to ensure cyclists are given their "fair share" of road space.

"Should they be sharing a traffic lane with an 18-wheel truck? People on bikes are vulnerable."

However, Hook argued that infrastructure currently in place for cyclists is adequate and that the responsibility was on cyclists to cycle in the appropriate lane.
