HIGH-LEVEL TREATMENTS <br />High-level treatments are high cost and are generally implemented on <br />high -volume and high-speed roadways. They are much more difficult <br />to implement unless they are justified based on traffic and pedestrian <br />volume. <br />Possible high-level treatments are outlined in Table 5 on page 27, and <br />examples of selected treatment options are shown below. For additional <br />information on Treatment Options, please see the.sources listed below. <br />PEDESTRIAN HYBRID <br />,V.,,,SVONI,Vis14,42409? <br />4,11414€44V'ar: <br />,..,4„.,.„.1,41p,st, • 458£(*S'kVkat%V.Vp.2kf'',Pct.'" <br />'XVIentatftg;'&3044ht 41*.

Determine the level of service (LOS) of the <br />crossing condition with the potential treatment op- <br />tions following the procedure as outlined in the 2010 <br />Highway Capacity Manual. An acceptable service level <br />should be determined by the agency. <br />It acceptable service levels cannot be met: <br />• Do nothing (consider leaving the crossing un- <br />marked and unsigned), <br />• Consider pedestrian routing to another location, <br />and/or <br />• Consider appropriate high-level treatments. <br />Sources: <br />"Minnesota's Best Practices for Pedestrian/BIcycle Safety," MnDOT Office of Traffic, Safety and <br />Technology, September 2013, <br />"Best Practices Synthesis and Guidance In At -Grade Trail -Crossing Treatments," Minnesota <br />Department of Transportation, St.Paul, MN, September 2013. <br />NCHRP Report 562: Improving Pedestrian Safety at Unsignalized Crossings.
