R street ne, an alley or a street?

So within the pass 15 mins there has been 4 cars that speed down R street ne alley(between lincoln and 1st ne) like its R street, now the reason why its pissing me off so much is the fact that is not a street and should not be used to pass the light at Lincoln and R n.e. There are homes on R street that the kids play in the alley to stay off the street and other people are in the alley cleaning their cars and such.
