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. "

Theresa May told the Commons it was a 100% failure rate, as all of the samples submitted so far since the Grenfell Tower fire had failed.
She urged local authorities and housing associations to "get on with the fire safety checks".
At least 79 people are feared to have been killed in the blaze on 14 June.
Meanwhile, regulator NHS Improvement said it has written to all NHS trusts and foundation trusts  to ask them to carry out urgent fire safety checks.
There are 36 organisations that need additional support to find out if they have cladding similar to Grenfell, it said, and fire safety tests on building material is expected to be completed "by early next week".
Mrs May told MPs that she expects to name a judge to head the public inquiry into the disaster soon.
She said 282 temporary properties had been identified for residents of the tower, 132 families have had their needs assessed and there have been 65 offers of temporary accommodation.
The government has made almost Â£1.25m of discretionary payments and will be giving an extra Â£1m to a local group of charities, trusts and foundations, Mrs May said.
Labour leader Jeremy Corbyn said the tragedy had "exposed the disastrous effect of austerity" and said: "Fewer inspectors, fewer building control inspectors, fewer planning inspectors - we all pay a price."
The blaze, which started in a fridge-freezer, destroyed 151 homes in the north Kensington block and in the surrounding area of the London Borough of Kensington and Chelsea.
Questions were raised about the cladding used on Grenfell in the immediate aftermath of the disaster and a nation-wide operation has taken place to identify and test buildings with similar cladding.
It has emerged that London Fire Brigade issued a warning to all 33 London councils about panels attached to the exterior of buildings in May this year, in a letter seen by the BBC.
On Tuesday, Mrs May said there should be a "major national investigation" into the use of cladding on high-rise towers.

KLM has added a 06:00 weekday flight from the Highlands airport and an evening flight from Schiphol.
Highlands and Islands Airports Limited (Hial) said the flights would allow people to spend a full day in the Netherlands before returning home.
It is the latest addition from KLM since it started Inverness-Amsterdam flights last year.
T in the Park organisers have announced an overhaul of the festival's campsite that will see it increase in size by a quarter.
