The Labour Party is to call for a flat fare on Dublin Bus and 500 extra vehicles in the Dáil this week.

In the debate to begin tomorrow evening, Labour will also urge the Government to build more park-and-ride facilities on the outskirts of the city and put the bus service "back at heart of public transport" in the capital.
Labour Party spokeswoman on transport Roisin Shortall said that rapid reform was necessary to prevent gridlock in the city.
"Despite the efforts of those involved in Operation Freeflow, traffic conditions in the greater Dublin area this winter have been worse than ever," said Ms Shortall.
"Even minor accidents or roadworks have a huge knock-on impact that can bring traffic to a standstill. A relatively minor accident on the M50 at 6.20am on Thursday led to hours of chaos with one bus taking three hours to complete an eight-mile journey from the west of the city to the city centre."
Ms Shortall was referring to a three-hour bus journey from Ongar, in west Dublin, to the city centre.
Labour is to recommend a flat fee of €1 for adults and 50 cents for children to entice people back on to buses.
Ms Shortall also criticised the Government's lack of investment in the bus service prior to, and since, the launch Transport 21, due for completion in 2015.
"A solution to our traffic problems depends on our ability to persuade commuters to leave their cars behind and to transfer to public transport. The experience with Dart, Luas and a number of quality bus corridors has shown that where there is a good public transport service, people will use it," said Ms Shortall.
"The Government has deliberately starved Dublin commuters of extra buses, with no increase in the Dublin Bus fleet from 2001 to late 2005. One year into Transport 21, only around 30 extra buses operate on our streets."
