The online survey, which was created by the Department of Public Safety and sent out to students, faculty and staff Nov. 30, had 9,034 responses as of Tuesday.
The preliminary results were given on Tuesday to members of TPAC, which is considering whether to charge for parking on campus at night.
The final decision probably will be made in February, although officials said the timetable is still far from certain.
Cheryl Stout, assistant director of parking services, said the survey was released mainly to determine who is driving to campus at night, why they are coming and where they are parking. "I don't believe that this is a decision-making tool as much as it is an informational tool."
Derek Poarch, director of DPS, said he has not interpreted the results of the survey. He said it is too early to analyze the data because the results are preliminary.
Stout said DPS will accept responses to the survey until next Friday.
Student Body President Justin Young said he still needs to digest the survey's results, but he said he is not convinced of their accuracy. Young has expressed concern about respondents' abilities to submit the survey more than once.
He also said he is worried about the way the results will be interpreted.
"It's one thing to say that students need to park at night," Young said. "It's another thing to charge for it."
