23727 HIGHWAY 99.PDFIIIIIIIIIIIIII 14069 23727 HWY 99 TRAFFIC CONTROL PLANS CITY OF EDMONDS SWIFT BUS RAPID TRANSIT STATIONS OWNER: COMMUNITY TRANSIT CONTRACTOR: WESTWATER CONSTRUCTION Resus va - 4 2009 SUCll.y OF EDNIONDSNry NOTES ON TRAFFIC CONTROL PLANS • ALL SIDEWALKS THAT HAVE BEEN REMOVED WILL BE RAMPED BACK UP TO MEET SIDEWALKS THAT REMAIN IN PLACE. THESE RAMPS WILL MEET ADA REQUIREMENTS FOR SIZE AND SLOPE. • TRAFFIC CONTROL DEVICES AND SIGNS WILL BE SPACED AND TAPERED ACCORDING TO THE ATTATCHED MUTCED CHARTS Table 6C-1. Suggested Advance Warning Sign Spacing Urban (low speed)* 30 (100) 30 (100) 30 (100) Urban (high speed)* 100 (350) 100 (350) 100 (350) Rural 150 (500) 150 (500) 150 (500) Expressway / Freeway 300 (1,000) 450 (1,500) 800 (2,640) Road Type Distance Between Signs** ABC * Speed category to be determined by highway agency ** Distances are shown in meters (feet). The column headings A, B, and C are the dimensions shown in Figures 6H-1 through 6H-46. The A dimension is the distance from the transition or point of restriction to the first sign. The B dimension is the distance between the first and second signs. The C dimension is the distance between the second and third signs. (The third sign is the first one in a three -sign series encountered by a driver approaching a temporary traffic control zone.) Typical distances for placement of advance warning signs on expressways and freeways should be longer because drivers are conditioned to uninterrupted now. Therefore, the advance warning sign placement should extend on these facilities as far as 800 in (0.5 mi) or more. On urban streets, the effective placement of the first warning sign in meters (feet) should range from 0.75 to 1.5 times the speed limit in km/h (4 to 8 times the speed limit in mph), with the high end of the range being used when speeds are relatively high. When a single advance warning sign is used (in cases such as low -speed residential streets), the advance warning area can be as short as 30 in (100 ft). When two or more advance warning signs are used on higher -speed streets, such as major arterials, the advance warning area should extend a greater distance (see Table 6C-1). Since rural highways are normally characterized by higher speeds, the effective placement of the first warning sign in meters (feet) should be substantially longer —from 1.5 to 2.25 times the speed limit in km/h (8 to 12 times the speed limit in mph). Since two or more advance warning signs are normally used for these conditions, the advance warning area should extend 450 in (1,500 ft) or more for open highway conditions (see Table 6C-1). Option: Advance warning may be eliminated when the activity area is sufficiently removed from the road users' Table 6C-3. Taper Length Criteria for Temporary Traffic Control Zones Type of Taper Taper Length (L)* Merging Taper at least L Shifting Taper at least 0.5L Shoulder Taper at least 0.33L One -Lane, Two -Way Traffic Taper 30 m (100 ft) maximum Downstream Taper 30 m (100 ft) per lane * Formulas for L are as follows: For speed limits of 60 km/h (40 mph) or less: For speed limits of 70 km/h (45 mph) or greater: Where: L = taper length in meters (feet) W = width of offset in meters (feet) S = posted speed limit, or off-peak 85th-percentile speed prior to work starting, or the anticipated operating speed in km/h (mph) Table 6C-3. Taper Length Criteria for Temporary Traffic Control Zones Type of Taper Taper Length (L)* Merging Taper at least L Shifting Taper at least 0.5L Shoulder Taper at least 0.33L One -Lane, Two -Way Traffic Taper 30 m (100 ft) maximum Downstream Taper 30 m (100 ft) per lane Formulas for L are as follows: For speed limits of 60 km/h (40 mph) or less: L = WS2/155 (L = WS2 / 60) For speed limits of 70 km/h (45 mph) or greater: L = WS/1.6 (L = WS) Where: L = taper length in meters (feet) W = width of offset in meters (feet) S = posted speed limit, or off-peak 85th-percentile speed prior to work starting, or the anticipated operating speed in km/h (mph) MUTCD Guidance: The spacing of traffic cones should not exceed a distance in feet equal to 1.0 times the speed limit in mph when used for taper channelization, and a distance in feet equal to 2.0 times the speed limit in mph when used for tangent channelization.
