1 Trucks are allowed on all City streets unless otherwise posted (by State law trucks must 2 be allowed on all Municipal State_Aided Roads eadymys.) 3 • The program intends to take a system -wide approach when addressing a neighborhood 4 traffic problem. For each project, city staff will determine a logical project boundary that 5 will be necessary for the approval process and will help address the issue of 6 displacement/diversion to other local streets. 7 • Implementation strategies will be limited to those local streets where the 85% speed 8 exceeds 5 mph above the posted speed limit or where other traffic impacts affecting the 9 livability of the neighborhood exists. 10 Implementation of traffic management strategies will be in accordance with the 11 procedures set forth in this document, and in keeping with sound engineering practices, 12 as well as be within the city's available financial and staff resources. 13 1 • Implementation of any devices will be consistent with the guidelines in the Minnesota 14 Manual on Uniform Traffic Control Devices. 15 Implementation of strategies shall be consistent with recommended strategies included 16 in the Mn /DOT Safety Handbook. 17 Initial deployments are considered temporary for study purposes and subject to an 18 interim review by City staff prior to permanent installation. 19 3.0 Traffic Management Background 20 The United States has used street closures and traffic diverters dating back to the late 1940s 21 and early 1950s, but it was not until the 1970s that Seattle, Washington completed area -wide 22 demonstrations of traffic management strategies. Since then, traffic management has been 23 continually studied and implemented throughout the United States. Strategies include street 24 closures, traffic diverters, speed humps /bumps, signing, increased enforcement and many 25 others, but they all are implemented to accomplish one of the following: 26 • Modify driver behavior (reduce speed) 27 • Modify traffic characteristics (reduce volume) 28 • Improve safety for pedestrian and bicyclists} 29 Traffic management can be simplified as a iwwe three step process: (1) identify the nature and 30 extent of traffic - related problems on a given street or areal (2) select and implement the 31 proper strategy for reducing the identified problem and (3) evaluate effectiveness, accept, 32 modify or revert. The traffic management strategies discussed in this document are solutions to 33 a narrowly defined set of problems and are not universally applicable or effective at solving all 34 problems. The kweRgA traffic management strategy used in the wrong application will not 35 improve conditions - it will only increase City costs and may even make conditions worse. 36 Since not all strategies are appropriate for every problem the City has developed a process to 37 identify the appropriate solutions. The process includes identifying the problem, evaluating 38 potential strategies, and implementing appropriate m^sstrategies while including public 39 participation and governmental approval. This process is summarized in Section 4. 40 The process and strategies included in this document are intended to be used on local streets 41 ^ ^ °mow ^ as legal Fesid ^^'i ^l ;tFeeM to reduce speeds and volumes. The goal is promote safety 42 for all public right of way users. (Streets withiR the Gity of Roseville are Glassified base 43 11/15/11
