Are you are resident of Highland Park? If you are, perhaps you might be interested in attending the neighborhood group meetings. From what I’ve been told, neighborhood groups are good place to address such matters.
If you are interested, or anyone else interested in Highland Park concerns, the next meeting of the Highland Park Action Committee is June 23rd at 1116 Holden SW, which is about four blocks east of the light you are talking about.
However, if you are NOT a resident of that area, I don’t have a clue where you should start. But, I bet some one else reading here does.
good luck
