Motorists are to be allowed to stay longer in on-street parking spaces in the centre of Edinburgh.
The council wants to encourage shoppers back to Princes Street
The maximum stay in more than 5,000 bays is to be extended to three and four hours.
The changes will come in in November and will be reviewed in January.
Council leader Donald Anderson said it was helping retailers recover from a dip in sales during the G8 summit at Gleneagles in July.
Motorists will be able to stay in the 3,245 parking bays in Queen Street to High Street and Charlotte Square to Leith Street for up to three hours.
The council said stays at the remaining 2,103 peripheral city centre parking bays would be increased to a maximum of four hours.
There will also be free bus journeys from park and ride sites at Hermiston and Ingliston at weekends until 31 December.
A marketing campaign promoting the city centre as an easy and convenient place to visit has also been launched.
A four-hour stay in Waverley Car Park on New Street and in the EICC car park on Morrison Street will cost between £3 and £5, the council said.
Mr Anderson said: "Now is the ideal time to shop in Edinburgh with the Winter Festivals and the festive season just round the corner.
"We've been working with retailers to find the best ways to encourage people to come in and have together devised a great Christmas present for shoppers.
"The free weekend park and rides will be a quick, hassle-free way to enjoy the city centre."
Ron Hewitt, chief executive of Edinburgh Chamber of Commerce, welcomed the new arrangements.
"These improvements should happily enhance the retail experience in the world class architectural gem which is the city centre without detracting from other objectives to fight congestion and improve pedestrian safety and environmental quality," he said.
