The move, announced by Melvin Benn, managing director of the Mean Fiddler, which holds the licence for the festival, is aimed at boosting the "green" credentials of the legendary three-day festival, which is being held at Worthy Farm in Somerset from Friday 22nd to Sunday 24th June.
Benn - responsible for the more operational side of the festival's organisation - has already arranged for 500 coaches to transport 25,000 fans from across the UK under plans to sell joint festival/travel tickets.
Around 10,000 fans were already expected to travel by coach, so the total number arriving at the site in a coach is set to be 35,000.
"We are looking to increase the capacity this year from 150,000 to 175,000," he said. "One of the significant impacts could be the additional traffic that will create.
"I have put together a combined ticket and coach package and we are arranging for the coaches to arrive at the least busiest times.
"This is a massive boost to the green credentials of Glastonbury."
The new ticket registration facility is open until 28 February. You will need to register first if you wish to buy a ticket this year. Click here for details.
