New Jersey Transit has launched a campaign geared toward making riders nicer. The campaign, in the form of posters going up on trains , focuses on the things that drive commuters crazy, such as people taking up multiple seats (Sad Sacks, in Trainjotting parlance) and of course the loud cellphone talkers.

The first 750 posters go up this week. Described by New Jersey Transit board member Flora Castillo as “a little edgy with a hint of of humor,” the posters will feature taglines like “How many seats do you need?”, “I can’t take the noise!” and “Clean your room!”

The campaign came to be based on a 30% increase in commuter complaints.
