WARNING SIGN INSTALLATION Warning signs are a critical signing element which provides information to the motoring public with respect to potential hazards in and or adjacent to the roadway. These signs include all yellow signs with black lettering as outlined in Minnesota Manual on Uniform Traffic Control Devices (MnMUTCD) Chapter 2C. Some typical signs that fall into this category are pedestrian crossing signs, school crossing signs, playground signs, curve signs, and other signs associated with the geometrics of the roadway. Warning signs are primarily for the benefit of the driver who is unacquainted with the roadway. It is very important that these signs be placed in areas in which the sign is truly justified so that drivers believe that the condition does exist. The use of warning signs should be kept to a minimum as the unnecessary use of warning signs tends to breed disrespect for all signs. In situations where the condition or activity is seasonal or temporary, the warning sign should be removed or covered when the condition or activity does not exist. Policies for installation of warning signs are discussed below: Analysis Procedure: Step 1: Requests for Warning Signs Evaluations This request can come from either a resident, the City Council, the Traffic Safety Committee, the school district, or from staff observation of a particular condition. If a request is made from a resident, a signed petition of more than 80% of the households within a 300' radius of the location must accompany the request. Step 2: Data Collection This step in the procedure should include collecting available data as listed below: • Average Daily Traffic Volume • Accident Summary • Site Visit • Pedestrian Traffic Volumes (if applicable) • Traffic Speeds • Site Topography Step 3: Sign Installation Evaluation An evaluation of the location should be completed to determine if the installation is justified. This procedure for specific types of warning signs is as follows: 1. Crossing Signs (pedestrian, school, etc.) a. Traffic Volume: If a daily traffic volume of a combined 1000 vehicles per day in both directions, exists on the roadway of the crossing or a peak hour volume of a combined 200 vehicles per hour on the crosswalk approaches exist and, b. Crossing Volume: A crossing volume of more than 30 pedestrians per day or 10 pedestrians per peak hour or, c. An 85th percentile speed on the roadway of more than 35 mph and a peak speed of two observations with more than 45 mph or, d. The safe stopping sight distance on the approach to the obstruction is less than 300 feet.
