November 19, 2003 Mr. Leon E. Towarn/cki Director of Public Works City of Martinsvilte P.O. Box 1112 55 West Church Street Martinsville, VA 24112-6209 RE: Traffic Signal Warrant Analysis E. Church St. @ Salmon St./Ridge Rd. M&C Commission No. 2206 Dear Leon: We have completed our investigation into the justification for or need of a traffic signal at the intersection of E. Church Street (Route 58) with Salmon Street/Ridge Road. Our evaluation has included a signal warrant analysis performed in accordance with the Manual on Uniform Traffic Control Devices for Streets and Highways, Millennium Edition. In our analysis we utilized 12-hour turning movement traffic counts tabulated in 15-minute increments as collected by the City of Martinsville on October 16, 2003. In addition to the signal warrant analysis, we made field observations of the intersection operations to observe any operational problems and delays being experienced by traffic. We also contacted the Martinsville Public Schools concerning the number of school buses that travel on Ridge Road and Salmon Street. We further reviewed the accident reports recorded for the intersection over the last four year period; 1999, 2000, 2001, and 2002. A careful analysis of traffic operations coupled with the judgment of experienced engineers has resulted in a series of warrants that define the minimum conditions under which signal installations may be justified. The warrants are contained in the Manual on Uniform Traffic Control Devices for Streets and Highways, Millennium Edition. "PC-Warrants for Windows" by lamar Technologies, Inc. Was the software package USed in the analyses for this study. Traffic control signals should not be installed unless one or more of the signal warrants in this Manual are met. In addition to meeting the warrants, installation of a traffic signal should improve the overall safety and/or operation of the intersection.
