09/12/2016 Streets,"or`Bicycle Boulevazds." Such streets typically have an average daily traffic volume of 5,000 vehicles or fewer. Requests are occasionally received to install traffic calming on streets classifxed as 'Local Streets," Pedeatrian Stre�s," or`Bicycle Boulevazds"that ca�ry higher traffic volumes, indicative of a higher functional classification of atreet (nominaily, above S,OOOADT, average daily trips). When considering such situaGot�n, the City must make a conscious policy decision. Is the street really a '7ocal" street that is simply impacted by too much tr�c which is traveling too fast? If so,traffic calming may be an appropriate response. Or is the atreet really fulfilling a necessary and appropriate "major collector" function in the City's circulation network - in essence, is its designation a misclasaification? In tho lattex case,tr�c calming is probably too restrictive and should not be used. For cut-tivough tr�c,the specific critcria to quaify for traffic calming is as follows: • 40%or more ADT on a local street ia cut-through tr�c between artedials or major roadways Traftic Safetv When traffic calming measures are installed to addreas documental or anticipated vehicle or pedestrian collisions,the causes of those collisions should be correctable by speed control. Proposed traffic calming must be evaluated in the field to verify that suc:h installations will not introduce or increase the potential for collisions. Vehicle Mix Typically, tr�c calming should not be installed on streets that carry significant volumes of truck tr�c unleas there is a reasonable altemative route for those vehicles. Generally,heavy or long-wheelbase trncics constituting up to five percent of all traffic ia considered normat. Special cons ideration may be given to a location where thexe is a significant genexator of huck traffic. Bicyclists, motorcyclis?ts, low-riders, and operators of other types of special vehicles ofla► consider traffic calming annoying. While potentially annoying to the�e types of roadway use�s, tr�c calming dces not constiUrte an unusual hazard or obstrudion for these vehicles. For this reason, the possible preaence of these vehicie typee is not a reason to deny approval of tr�c calming in circumstances where it would otherwise appear desirable or needed. Emergencv Vehide Aceess Traffic calming is typicaliy not installed on streets that are defined or used as primary emergency vehicle access routes. If traffic calming is deemed necessary on any roadway identified as a primary response route,the design must be coordinated with the emergency responders. Primary emergency vehicle routes are comprised of two typea of atrcets: 1. Routes used by emergency vehicles to cross large parts of the community or on patha logically nsed to service large numbers of potential destinationa. Routes of thia type are generally ineligible for traffic calming through this document based on their functional class�cation. 2. Streets of generally local character which also serve as the immediate egreas route from an emergency vehicle diapatch point or a s t h e immediate acoess route to a regular destination for emergency vehicles (such as where a fire station or a hospital emergency ' room access is located on a street classified "local").
