text: Last year's event, the first at Strathallan in Perthshire, was criticised over traffic issues and antisocial behaviour.
  DF Concerts said improvements include colour-coded zones, better signage and 24-hour dedicated management teams.
  This year's event will take place between 8 July and 10 July.
  The Stone Roses, Calvin Harris and Red Hot Chili Peppers will headline the main stage over the three nights.
  Last year's T in the Park had a daily attendance of about 85,000 people with an estimated 70,000 of those camping.
  DF Concerts has produced an animated video highlighting the new campsite layout.
  T in the Park security manager Colin Brown, said: "We have overhauled the campsite layout and management and guarantee there will be well-informed stewards on hand to assist with any questions.
  "The layout, clearly marked-out zones and improved signage will make getting about much easier, meaning our campers can concentrate on having a good time."
  DF Concerts said the Slam and King Tut's tents would open exclusively for campers on Thursday 7 July.
  Last week, the promoter announced that this year's festival arena will increase in size by a third.
  It will publish revised transport plans for the event next week.
  Campsite entertainment manager Gail MacKenzie said: "We know that the campsite is a huge part of the T in the Park experience and have listened to feedback from last year.
  "As a result the entertainment will be enhanced and we're even opening the King Tut's Tent on the Thursday for the first time ever. "
