An announcement on the appointment of a taxi industry regulator is expected to be made by the Minister for Transport, Mr Brennan, today as taxi-drivers prepare for a protest in Dublin tomorrow.
The taxi-drivers are staging the protest to highlight a number of issues, including deregulation.
Traffic disruption is expected in Dublin city centre.
One of the unions' demands has been for a taxi industry regulator and the Minister is expected to announce today what the role of the regulator will be.
It is believed the Minister brought the proposals to Cabinet yesterday.
The taxi-drivers protest in Dublin was chosen for tomorrow to mark the second anniversary of deregulation.
Yesterday, senior gardaí from the traffic section met representatives of the taxi unions to work out a plan to minimise disruption to traffic during the Dublin protest. They will meet again today to finalise arrangements.
The taxi drivers, members of the National Taxi Drivers' Union of Ireland, the Irish Taxi Drivers' Federation and SIPTU, will assemble at the Papal Cross, Phoenix Park, at 1 p.m. The unions stated yesterday that between 600 and 700 are expected.
After speeches, the convoy is expected to move off at 2 p.m. down the quays until it arrives at O'Connell Bridge.
The plan being discussed is for a representative number of cars, maybe 50, to continue to the Dáil in Kildare Street to hand in protest letters while the other taxis will peel off and go back to work.
A Garda spokesman said yesterday that originally 1,300 cars were expected but the final arrangements had yet to be made. Traffic disruption is certain.
Yesterday, the general secretary of the National Taxi Drivers' Union of Ireland, Mr Tommy Gorman, said they were working with the gardaí as they did not want to disrupt traffic and that was the reason there would be no more than 600 to 700 cars in the park.
Mr Gorman said they were demanding that the Government prioritised the issues concerning the appointment of a regulator, the number of "double jobbers", the erosion of income and rising insurance costs.
There were 2,722 taxis on the road before deregulation and now there are 9,062, he said.
Mr Jerry Brennan of SIPTU said they had been left with the fallout of deregulation.
"We need to be met half way by the Government. We want some form of re-regulation", he said.
Meanwhile, a Dublin lobby group yesterday confirmed that its petition on taxi deregulation would be given a public hearing on December 10th in the European Parliament in Brussels.
The group, FAIR (Families Advocate Immediate Redress), which represents wives, widows and partners of pre-deregulation taxi drivers, will address the European Petititions Committee.
