With four weeks to go until the festival, organisers are advising revellers “bus is best” and warning drivers that satellite navigation systems will not work to get them to the site at Strathallan, Perth and Kinross.
A new transport plan for this year’s event includes separate roads for buses and cars at the site, an improved bus station in a new location, new car parks and a dedicated pick-up and drop-off point.
Last year, fans were caught up in lengthy queues and traffic gridlock around the site.
Ian Martin, transport manager at T in the Park, said: “We’ve made some major changes to our transport plans and we strongly advise people take the time to plan their journey.
“Our main message is that bus is best. You’ll be able to relax while the driver gets you to the festival safely, quickly and closest to the site.
“We are confident in the set-up for 2016 and would remind fans that T in the Park is Scotland’s biggest festival, so an element of patience will always be required, but waiting times will be of a normal level for an event of this scale.
“Please be respectful of the local community and, if you are driving, leave time for toilet stops at service stations. Remember there is a strict drink-driving limit in Scotland, so don’t risk it.”
To help festival-goers plan their journey, the site trafficscotland.org/titp is now running providing up-to-date travel information.
Due to temporary road closures, organisers warn satellite navigation systems will be “wrong” and ask drivers to follow event signs.
Calvin Harris, the Stone Roses and the Red Hot Chili Peppers are scheduled to headline the three-day festival.
