An online map showing how Dubliners will be affected by the redesign of the bus network has been launched.
It means commuters can check how their route will change under the Bus Connects proposals.
Some of the changes include scrapping route numbers in favour of 'spines' which splinter off at various points.
Independent councillor for Ballymun, Noeleen Reilly, says that in itself is a huge cause of concern.
"We are seeing a significant increase in the number of buses people are going to have to get to a destination, that they're only getting one bus to now. There are areas like Wadelai and the Tolka estate that are losing their bus altogether and there are a huge amount of senior citizens living in those areas."
A spokesperson for the National Transport Authority insists those two estates will still be served, but some residents may have to walk further to get their bus. However, "the buses they are walking to (will be) far more frequent than the current services; some of which only come once an hour."
