The Rs have endured a miserable start to the campaign, with chairman Tony Fernandes admitting in the build-up that it has been "nothing short of a disaster".
Harry Redknapp's side went some way to making amends Saturday, though, as Adel Taarabt inspired QPR to victory against west London rivals Fulham at Loftus Road.
The Morocco international's brace secured a 2-1 win that moves the Hoops off the bottom of the table, and left-back Traore knows the result has to act as a catalyst.
"It was definitely a relief to get that win," he told Press Association Sport.
"After coming so close in a lot of the games, I think it was a big relief for the players, for the fans and for the club.
"I think last week at Wigan we did well. We went 2-1 up and unfortunately they scored one back.
"There are a few I can think of off the top of my head where we came close, but it was a good all-round performance.
"I still think it is going to be really hard and I think that before this game we were unbeaten in three.
"It was really important to get that win, like Harry said, so I think now we can start our season."
Saturday's victory cuts the gap on 17th place to five points and continues Redknapp's fine start to life at the club.
QPR are unbeaten since he succeeded Mark Hughes at the helm, with three draws before Saturday's win against Fulham.
"He is very good with the players," Traore said of Redknapp. "He likes to tell the players their strengths.
"Obviously that brings confidence to the players. He is a very good motivator as well as a good coach.
"He is a good guy to coach QPR and I feel I have improved since he came in.
"I always try and improve anyway regardless of the manager, but I am trying to improve every game."
As good as QPR were Saturday, opponents Fulham never really looked a threat at Loftus Road.
Mladen Petric's late goal ensured a nervy ending but a leveller would have been harsh on the hosts, with Aaron Hughes conceding the Cottagers let themselves down.
"It is disappointing," the defender told Press Association Sport. "Any loss is disappointing, especially a derby loss.
"It was a hard-fought game on Monday night against Newcastle and a hard-fought game against QPR. It is just a shame we couldn't come out the right side of it.
"We knew they were going to be up for it. They are fighting for their lives down there, so we knew from the off it would be like that.
"Take away everything else, the qualities they have and all the other things, the first thing they were going to have was going to be a lot of fight.
"They showed that and we got away with a couple of things in the first half. We got ourselves back in the game a little bit, we're just disappointed with the goals we conceded.
"After a big performance on Monday night, we sort of let ourselves down. We came up a little bit short."
Saturday's loss was compounded by an injury to right-back Sascha Riether.
The German has impressed since arriving at Fulham in the summer but limped off at half-time, taking to Twitter overnight to reveal the nature of his injury.
"Sorry to all the fulham Fans for such a disappointing Game," Riether said. "Meeting with the German Doc in munich because of a hamstring injury."
