All five days of the Ascot meeting are expected to be a sell-out

Around 40,000 people a day are expected to travel into the city by road during the five-day event from 14-18 June.

All cars and coaches will be channelled via the A64 into huge car parks at both ends of the Knavesmire course.

Up to 13,000 people a day arriving by train and 16,000 travelling by taxi, public transport or on foot will follow fixed routes to minimise disruption.

Bus company FirstBus has commissioned a new fleet of 35 buses to shuttle racegoers from the railway station to the course.

And taxi and private hire cab operators have joined forces under one umbrella group to co-ordinate their movements. They will use Terry Avenue as a dedicated route to and from the event.

All race traffic will be channelled along the A64

A water bus service will operate between the city centre and the racecourse, departing from the Moat House Hotel on North Street.

The cost of implementing the plans, more than �250,000, will be met by Royal Ascot management.

The city council says it has learned from mistakes made at last year's Ebor meeting, when traffic queues on the A64 stretched as far back as Tadcaster and people living near the course suffered major disruption.

As Royal Ascot is an all-ticket event, racegoers will receive travel information with their tickets, ensuring they are aware that they must use the A64 approach route.

Drivers attempting to get to the racecourse by other routes will be turned back by police, the city council said.

Minimise impact

The authority also plans to "insulate" residents in the nearby South Bank area by closing off roads to anyone who does not live there.

Gates manned by police officers will ensure unwanted drivers or pedestrians cannot enter.

The council's acting director for environment and development, Bill Woolley, said: "The aims of the plan are to enable up to 70,000 visitors each day to get in and out of the racecourse as smoothly as possible and to minimise the impact of the race meeting on the rest of the city.

"We have learnt a number of important lessons from the traffic management trial at last year's Ebor meeting and have refined our recommendations accordingly.

"However, with such a large influx of people coming into the city in the space of a few hours some congestion is inevitable."
