I was there at Mecspe, a trade fair dedicated to mechanical production. Despite the large influx of visitors, there was a limited queue to access the car park (8 euros per day) and even the pavilions were not too crowded, thanks to the space between the different stands.
A tip: if you are coming from the north, use the Parma Ovest motorway exit. You drive a few more miles but avoid standing in the emergency lane as often happens at the Parma Centro exit.
