I'm a bit confused by this, and I'm not arguing, I'm just providing another perspective.
I've been going to the UM-F$U games since 1986. Maybe the last couple have not been bad, due to both teams sucking, but the vast majority of traffic for the games in Tallahassee comes from the east. Most people exit at US 90, and there is usually slow traffic that starts AT the exit, and extends for over 5 miles. Maybe the rise of Waze/Google Maps has convinced people to get off at the US 319 exit now. Regardless, there's only one major east-west road (Tennessee Street) and one major north-south street (Monroe) once you get within a mile or two of the stadium. There are usually a ton of cops around (it IS the state capital), and if you know where you are going, you can take side streets to get to your parking complex more quickly. Getting INTO Doak isn't terrible, as people arrive at a wide variety of times, but exiting Doak and the surrounding areas is a DISASTER. There aren't many hotels in the area, so people are desperately trying to get back to civilization on I-10, which is nowhere near as wide as it needs to be for gameday traffic, though it is GREAT when you are simply trying to avoid exiting in Tallahassee because you are super-focused on getting to Jacksonville or Pensacola.
I've been going to the UM-UiF games since 1986, plus I have a graduate degree from UiF. While I-75 is one lane wider in each direction than I-10, you still have similar issues with gameday traffic. Most of the Hogtown gameday traffic comes from the south (Orlando/Tampa/Miami), though there has been a growing flow from Jacksonville which can access Hogtown from the backside, on 24, 26, or 20. Even though there are three main roads you can take to get towards the campus (Williston, Archer, and Newberry), we all know that nearly everyone takes Archer, due to the high concentration of national chain restaurants and stores that fill both sides of the road. ****, I recently got off at Archer (to gas up at Wawa) in the mid-afternoon on a weekday, and it was a DISASTER. Expansion of the area around Shands, as well as ongoing construction, turned a 2.5 mile errand into a 25 minute suicide-contemplation. I can only imagine the 2022 gameday traffic. The only thing that makes EXITING Florida Field at Ben Hill Griffin Stadium tolerable is that Hogtown has SLIGHTLY more hotels, and the fact that the Gaytor fans like to try to recapture their drunken/rapey college glory days by spending a few hours in their favorite local name-changed-since-they-were-there bars as they silently pray that someone recognizes them and shouts out their name in a postive fashion.
UCF might just be the best of the bunch, largely because it has the smallest stadium of the three (though the largest student population, the vast majority of which cannot get into the games due to the disparity between enrollment and stadium capacity). I've been to many games there, and one of my nephews currently lives in Tower 1, just blocks from the stadium. UCF has fairly close proximity to toll roads such as the East-West Expressway and the Beltway. However, it cannot be denied that Alafaya and University are dual ****-shows on gameday. Part of the problem is that there is a lot of pedestrian and bike traffic, because so much of the housing (and restaurants) are located nearby on Alafaya or University. UCF would greatly benefit from about 10 or 12 pedestrian bridges. UCF has the weird distinction of possibly being worse for PRE-GAME traffic than post-game, as there are HUGE numbers of students who show up to tailgate in the Memory Mall "green" area, and then go home to watch the game on teevee, because there just aren't enough seats to accommodate them.
Overall, I believe that F$U and UCF are better-equipped to utilize police to assist with gameday traffic, while UiF just has to rely on a lot of people just knowing where they are going. Recent "poor performance" has probably helped the gameday traffic situation, but if UiF or F$U ever get good again, or UCF expands the stadium, then it will get bad again. Keep in mind, I have years of experience with the largest sports venue in Florida (Daytona International Speedway), and I cannot emphasize how helpful it is to have a HUGE police presence, potential "one-direction" flow on certain roadways, shuttles, and pedestrian bridges in place. Even then...it takes a while to get into (but especially out of) Daytona on race days.
