1 Implementation limited to local streets. A local street is a street under the jurisdiction of 2 the City of Roseville. (Re ^''^'°^l^ 9F eelleeteFs) ;de Rtified OR the Reseyollp 4 • Implementation of strategies will be funded by a combination of city funds and 5 neighborhood participation. 6 • Trucks are allowed on all City streets unless otherwise posted (by State law trucks must 7 I be allowed on all Municipal State_Aided roads.) 8 • The program intends to take a system -wide approach when addressing a neighborhood 9 traffic problem. For each project, city staff will determine a logical project boundary that 10 will be necessary for the approval process and will help address the issue of 11 displacement/diversion to other local streets. 12 Implementation strategies will be limited to those local streets where the 85% speed 13 exceeds 5 mph above the posted speed limit or where other traffic impacts affecting the 14 livability of the neighborhood exists. 15 Implementation of traffic management strategies will be in accordance with the 16 procedures set forth in this document, and in keeping with sound engineering practices, 17 as well as be within the city's available financial and staff resources. 18 1 • Implementation of any devices will be consistent with the guidelines in the Minnesota 19 Manual on Uniform Traffic Control Devices. 20 Implementation of strategies shall be consistent with recommended strategies included 21 in the Mn /DOT Safety Handbook- JD 22 Initial deployments are considered temporary for study purposes and subject to an 23 interim review by City staff prior to permanent installation. 24 3.0 Traffic Management Background 25 The United States has used street closures and traffic diverters dating back to the late 1940s 26 and early 1950s, but it was not until the 1970s that Seattle, Washington completed area -wide 27 demonstrations of traffic management strategies. Since then, traffic management has been 28 continually studied and implemented throughout the United States. Strategies include street 29 closures, traffic diverters, speed humps /bumps, signing, increased enforcement and many 30 others, but they all are implemented to accomplish one of the following: 31 • Modify driver behavior (reduce speed) 32 • Modify traffic characteristics (reduce volume) 33 • Improve safety for pedestrian and bicyclists} 34 Traffic management can be simplified as a tAQ hree step process: (1) identify the nature and 35 extent of traffic - related problems on a given street or areal (2) select and implement the 36 proper strategy for reducing the identified problem and (3) evaluate effectiveness, accept, 37 modify or revert- JD. The traffic management strategies discussed in this document are 38 solutions to a narrowly defined set of problems and are not universally applicable or effective at 39 1 solving all problems. T"^• Lk traffic management strategy used in the wrong application 40 will not improve conditions - it will only increase City costs and may even make conditions 41 worse.
