Cops just cleared Paul Walker's fans from the crash site ... in order to prepare for a private family memorial ... TMZ has learned.
Thousands of Walker's fans have been gathering on the site since Saturday afternoon to pay their respects -- but moments ago sheriff's deputies dispersed the crowd.
A source close to Paul and the driver of the Porsche, Roger Rodas, tells TMZ their families just wanted some private time to mourn while visiting the site of the tragedy.
According to law enforcement sources ... a production company also obtained a permit to film in the area tonight. Unclear at this point what is being shot and by whom.
