FOREIGN ministers from more than 40 countries, including US Secretary of State, Hillary Clinton, are expected to attend next week's massive international security conference in Dublin.
Officials from the Department of Foreign Affairs have disclosed that over 1,500 delegates, officials and media will be involved.
It is estimated that the two-day conference at the RDS will give a €2.35m boost to the economy in the capital.
Tanaiste Eamon Gilmore will host the meeting of the ministerial council of the Organisation for Security and Co-operation in Europe as Ireland has the presidency this year.
Gardai said yesterday they hoped to keep disruption to a minimum but warned that parking restrictions and traffic diversions would take place around Ballsbridge throughout the week.
Full details of the restrictions at Simmonscourt and surrounding roads are being published on the garda website, garda.ie.
Garda Supt Barry O'Brien, officer in charge of the Donnybrook district, said their message to the public was that Dublin would remain open for business but access in some areas would be restricted, except for residents.
Peaceful protests will be allowed but gardai warned that if anybody broke the law they would gather evidence against them and bring them before the courts.
A big security operation is also being planned to protect the visiting ministers but will not be finalised until gardai receive all of the travelling arrangements for the VIPs.
Gardai are also preparing contingency plans to cope with protests over the Budget as the conference gets under way on Thursday.
Some restrictions on traffic are also likely as ministers are ferried to Ballsbridge through the city and around Dublin Castle, where an official dinner for the ministers is being held on Thursday night, followed by a reception at the Guinness Storehouse.
