FOUR-WAY STOP AT BROOKLAND PARK PLACE/MELROSE COURT Recommendation: Traffic Engineering recommends that a four-way stop not be installed at Brookland Park Place and Melrose Court. Discussion: The Manual on Uniform Traffic Control Devices (MUTCD) specifically directs that stop signs not be used for speed control. Stop signs are meant only to either protect or partition right-of-way. Other jurisdictions have conducted studies to determine the effectiveness of stop sign installation as a speed control measure. These studies indicate that mid -block speeds remain the same or are higher after stop sign installation than before stop sign installation. While localized speed is reduced in the area of the stop sign, driVers'tend to compensate for their perceived delay in the mid -block area. SPEED LIMIT REDUCTION Recommendation: Traffic Engineering recommends that the speed limit not be reduced from 25 mph to 15 mph. Discussion: Traffic Engineering Division conducted spot speed studies on Melrose Court prior to its closure. These studies indicated that the eighty- fifth percentile of drivers using Melrose Court at that time were traveling at 28 mph or less. The average driver perceived a safe driving condition with dry pavement and clear weather conditions with a 28 mph speed limit. Drivers adjust their speed to perceived conditions. If drivers perceive excessive side friction or congestion caused by oncoming cars, the typical driver will modify his driving behavior and speed to account for these conditions.

Such speed limit shall be effective when proper and appropriate signs giving notice thereof are erected at such intersections or other place or part of the street. Attached is a detailed report on this matter prepared by the Traffic Engineer. Although the criteria includes significant issues such as accident rate, pedestrian activity (both under 12 and over 12), parking, width and type of shoulders, and presence and location of sidewalks, the conclusion does not accommodate a 15 mile per hour speed zone. This item will be discussed at the informal Council session on Monday. bj5/1 MICROFILMED BY JORM MICR+LA9 CEDAR RAPIDS • DES MOINES /SDI' i i " City of Iowa Cin MEMORANDUM Date: September 18, 1980 To: Neal Berlin, City Manager From: James Brachtel, Traffic Engineer Re: Council's Request for a Study into a Reduced Speed Zone on Melrose Court City Council has expressed an interest in reducing the speed zone for Melrose Court from the residential speed limit of 25 miles per hour to 15 miles per hour., The Traffic Engineering Division undertook a study of conditions on Melrose Court to determine the advisability of this reduced speed zone. The criteria used in this speed study is the same criteria used by the Iowa Department of Transportation in similar investigations and studies. The study as used by the Iowa DOT is a two part study. The first part of the study is called a Minimum Study; the second part of the study is called a Refined Study. The Minimum Study is based upon a spot speed study, test runs, speed of the facility, length of the proposed zone and the average distance between intersections. These factors are detailed in Attachment A. The Refined Study is an attempt to use the results of the Minimum Study and make adjustments for conditions such as street classification, number of land use access points per mile, roadway cross section elements (including pavement width, number of lanes, presence of a median, presence of shoulders, presence of sidewalks), the alignment of the facility, traffic and pedestrian conditions and accident rate. These factors are tabled and shown in Attachment B. Also attached are the tables from which the appropriate adjustment factors were taken. The Minimum Study would support a 30 mph speed zone. This reflects the rural bias of this portion of the IDOT procedure. Clearly the standard 25 mph speed limit should be selected in place of the charted 30 mph. The Refined Study results support a speed limit of 27.5 mph. This should be rounded down to 25 mph. RECOMMENDATION After a careful analysis and review of the Iowa DOT procedure and pertinent local data it is my recommendation that the speed zone for Melrose Court be maintained at 25 miles per hour and not reduced to a 15 mile per hour speed zone. Should you have any questions or comments regarding this, please don't hesitate to contact me. bj4/2 MICROFILMED BY JORM MICR+LAB CEDAR RAPIDS • DES MOINES 1801 n " City of Iowa Cin MEMORANDUM Date: September 18, 1980 To: Neal Berlin, City Manager From: James Brachtel, Traffic Engineer Re: Council's Request for a Study into a Reduced Speed Zone on Melrose Court City Council has expressed an interest in reducing the speed zone for Melrose Court from the residential speed limit of 25 miles per hour to 15 miles per hour., The Traffic Engineering Division undertook a study of conditions on Melrose Court to determine the advisability of this reduced speed zone.
