LAPD to Travis Barker -- You're Pissed, Let's Talk

The LAPD wants a face-to-face meeting with Travis Barker -- hoping to find out why the rocker has accused an officer of crossing the line during a routine traffic stop this weekend ... TMZ has learned.

Barker was pulled over Sunday after an officer noticed the drummer's car had no license plate and illegally tinted windows. Cops confirm Barker was issued a "fix-it" ticket and sent on his way.

But after the incident, Barker BLASTED the cop on Twitter -- saying, "Officer FARD of LAPD, get a life man. Find some bank robbers or do something productive 2 do with your time. I know high school was hard 4 u."

Barker continued, "Pullin me over interrogating me & acting like u did over tinted windows till u scared the piss out my kids was uncalled 4.Job well done man."

He also claims the officer "had the nerve" to ask if he had guns in the car.

Now, TMZ has learned ... Sgt. Riggs of the Topanga Station tells TMZ, "I'd like to invite Travis to speak with me about the incident ... and possibly discuss the situation with the officers involved."
