Terry Maurer <br />July 20, 2000 <br />Page 2 of 2 <br /> <br />The license numbers of eastbound vehicles seen at Station I were compared to the license <br />numbers of northbound vehicles seen at Station 2. A total of 25 vehicles were seen at both <br />locations traveling EB/NB within the given time criteria. In the reverse direction (from Wilson St <br />southbound to 193rd Ave westbound), a total of 11 vehicles were seen at both locations. As a <br />percentage, about 11.5% of the vehicles on the east leg of 193rd Ave/Dodge St intersection are <br />traveling through the subdivision to and from the Wilson Street access point. <br /> <br />Vehicle counts collected at Station 1 indicate that daily traffic volumes on 193rd Avenue east of <br />Dodge Street are approximately 1,350 vehicles per day. At the Wilson Street location, the daily <br />volume is approximately 700 vehicles per day. Based on these daily totals and the number of <br />through trips surveyed, it is estimated that about 150 to 160 vehicles travel through the <br />subdivision on a typical weekday. This is likely a worst-case scenario given that the lessening <br />of congestion during the off-peak periods most likely makes the subdivision shortcut less <br />appealing to ddvers during that time. Assuming that all of these through tdps occur dudng a 12- <br />hour pedod of a typical weekday, one vehicle would travel through the subdivision every 4.5 <br />minutes, on average. During the survey, most of the vehicles traveling through the subdivision <br />did so between 4:30 PM and 6:00 PM. Therefore, during this time period, one vehicle traveled <br />through the subdivision every 3 minutes. <br /> <br />Conclusions <br /> <br />According to the report titled Residential Street Design and Traffic Control by the Institute of <br />Transportation Engineers (ITE), local streets such as 193rd Avenue, Auburn Street, and Wilson <br />Street through Hillside Estates should have a primary function of providing access to residences <br />adjacent to the roadway versus providing for through vehicle movement. However, it is <br />acceptable to provide a Iow level of through movement along local streets. Based on past <br />experience and the guidance provided by (ITE), the level of through traffic on these roadways <br />does not appear to be high enough to warrant removing or deterring through traffic. Also, speed <br />studies conducted in the area indicate that speeding is not a major problem. <br /> <br />If Aubum Street were made into a cul-de-sac in order to remove through tdps, the traffic <br />volumes on the roadways studied would not be greatly reduced. This is especially true for 193r~ <br />Avenue which also serves as an east-west collector for the subdivision. At this time, traffic on <br />this roadway is being generated primarily by the residents traveling to and from TH 169 and <br />adjacent development. This residential traffic on 193rd Avenue will most likely grow as the <br />subdivision develops to the east regardless if Aubum Street is made into a cul-de-sac. In <br />addition, if Auburn Street was closed off, emergency vehicles would have fewer travel options <br />through the area. To summarize, based on the information examined, the magnitude of through <br />traffic in Hillside Estates does not appear to be unusual or problematic.
