The PWM Traffic Operations Section is <br />responsible for the overall administration of the program. Traffic Operations staff under the direction of the <br />City Traffic Engineer conduct investigations to determine recommendations for safe speeds on local roads and <br />streets.

Citizens may request the city study a particular speed zone. The <br />investigations use procedures in accordance with nationally accepted traffic engineering standards. Factors <br />taken into consideration are crash history, 85th percentile speed, roadside culture, traffic volumes, and roadway <br />alignment, width and surface type and condition. <br />When the investigation is complete, a report with photographs detailing the existing conditions and proposed <br />changes is prepared. All speed zone change requests initiated by the city are authorized and signed by the City <br />Traffic Engineer prior to forwarding to ODOT. If the SSCB agrees with the recommendation, the new speed <br />zone is established by resolution. Signs are installed in accordance with APWA Policies 31.2 and 31.5 and the <br />Traffic Manual. <br />If ODOT and the local road authority cannot reach agreement on the setting of a speed zone, the speed zone <br />request is referred to the Speed Zone Review Panel.
