<br />Traffic Commission <br />6801 Delmar Boulevard, University City, Missouri 63130, Phone: (314) 505-8560, Fax: (314) 862-0694 <br /> <br />Sinan Alpaslan spoke about speed limits that included an introduction into how the speed limits are <br />governed and their upper limits for different types of roadways from freeways and expressways to local <br />roads. Mr. Alpaslan then described how prevailing speed is determined on a section of a roadway and <br />the use of this information for setting a speed limit on the roadway and related engineering and legal <br />limitations. <br />Mr. Alpaslan showed a chart as an example of result of a speed study and went over the determination <br />of speed limit on this example. There are other data factors that are taken into consideration and used <br />as reduction points for either an initial setting or an adjustment of speed limits and these are 1) Fatality <br />and Disabling Injury Crash Rate, 2) Total Crash Rate, 3) Pedestrian Traffic, 4) Parking, 5) Adjacent <br />Development, and 6) Physical Roadway Conditions. Mr. Alpaslan then showed a graph about the <br />applicable safe stopping distances when traveling at different speeds as a reason of why the speed <br />limits and their enforcement are important for safety. Mr. Alpaslan mentioned the importance of data <br />for use in engineering formulae and accurately setting speed limits and indicated that the Department <br />of Public Works and Parks is in the process of obtaining a speed trailer / radar monitor in order to be <br />able to gather data effectively. <br />Answering questions from Commissioners, Mr. Alpaslan mentioned a possible upcoming change in the <br />City’s municipal code (chapter 10.20) that relates to speed limits to introduce street sections with 15 <br />MPH and 20 MPH speed limits, which will be used on Delmar Loop and the approaches of the <br />proposed roundabout in front of the City Hall in the beginning and can be applied to other streets <br />based on speed studies and Traffic Commission/Council approval. <br />Currently there is no 15 MPH speed limit applicable in University City other than alleys and 20 MPH <br />speed limit is only applicable in school zones, which need to meet other additional school zone criteria <br />to be assigned. In response to a speed limit related question about intersection safety at North & <br />South Rd.- Gannon Ave., Mr. Alpaslan indicated that a speed limit reduction in this area would be a <br />good option to explore due to the limited sight distance and reminded the Commissioners that it would <br />need the County’s approval since the section of North & South in question is under the County’s <br />jurisdiction. Another suggestion was to restrict certain type of vehicle parking near this intersection for <br />better sight distance. Mr. Alpaslan indicated that staff would work with the County on available options <br />to increase safety. <br /> <br />7Miscellaneous Business <br />. <br /> <br />Resident concerns & Council meeting attendance: <br /> <br /> <br />Speed Limit Signs <br /> : Mr. Green suggested that speed limit signs be put on Eastover due to the <br />rate of speed the commuters are traveling. <br /> <br /> <br />No parking sign <br /> : Mr. Green suggested that a no parking sign be put up on the right side of <br />Eastover to prevent accidents. <br /> <br />Traffic Commission Minutes – October 9, 2013 <br />Page 3 <br /> <br /> <br />
