Do i have a chance at fighting this ticket in court?

I got a ticket yesterday for "failure to observe sign". I was driving from little falls new jersey to clifton but i couldnt get over on 46 so i ended up getting lost. I ended up in Paterson where I go to school and I stopped at a stop sign. I went foward a little before I realized there was a do not enter sign. a cop was right there and he yelled at me and made me pull over. I did not pass the sign. I stopped as soon as a realized an there was no other cars around. the cop took my liscene reg, ect and he told me he was gunna give me a "break" since i wasnt from paterson and i was lost. he also said i wouldnt get points on my lisence. well he completely lied because when i got home i looked at the ticket and he checked failure to observe sign which is a ticket for $85 and i have to go to court so i have to pay an additional $50. i didnt pass the sign and i've never been pulled over before or have gotten in accident. i don't think it's fair considering i didnt even pass the sign . i booked a hotel in seaside for memorial day weekend with my friends and now i can't go because of this ticket. so since i already paid half the money which is $74 i'm really losing $209 :( I don't mean to complain but I feel like I should of gotten a break. The cop was laughing at me too. I had a panic attack after I got home because I've been under so much stress lately. This really sucks.
