Petitioning for Traffic Enforcement Agents | Where To Start?

I recently moved to a 2nd story apartment right on the border of Park Slope and Prospect Heights where Saint Marks meets Flatbush meets 6th Ave meets Bergen St. Prior to signing our lease, we were more concerned about potential noise from the restaurant below than from Flatbush. Oh how naïve we were. 

During rush hours and on weekends, the above mentioned streets create one large, congested, poorly managed intersection that sees drivers "blocking the box" and thus backing up traffic for nearly two blocks in every direction. Of course, this results in honking. Massive amounts of frustrated honking. The auditory perils of living in New York on a busy thoroughfare are well known and can be complained about just so much before one becomes whiney and privileged. 

That being said, it only takes an observer a few minutes to realize that the majority of the backups and resultant frustration could be prevented if the city would install two Traffic Enforcement Agents to keep motorists from jamming up the intersections. (Note: we're making the assumption that said TEAs would actually be performing their job as required to make this scenario plausible). As you travel along Flatbush into the city, every intersection has TEAs on duty so why not here? 

In your experience, what would you suggest to be the most effective way to petition the city/police department to install TEAs at these intersections? 

Many thanks,
