I'm informed that speed signs do not make a difference, because all drivers know that neighborhood streets run at 25 miles per hour. Summit street is used as a major conduit for much of the day and takes the load off Miller for East West traffic. There have been many accidents over the last decade on Summit. All of the people I asked for an opinion who live on Summit with one exception, feel the traffic speeding on summit is a big problem. To contradict the belief that speed signs for 25MPH are not necessary I offer the fact that there is such a sign on DEVONSHIRE east of Arlington, where traffic is minimal. Devonshire, both before and after Arlington, has speed bumps too. I have seen the 25 mph sign in many places. We would a couple signs installed on Summit that inform drivers of the legal speed.
