Capacity is assumed to be at a critical lane volume of 1400 vehicles per hour. <br />(Highway Capacity Planning Level Analysis) <br />2. Local traffic from the southwest quadrant has not been generated and applied to <br />those alternatives with a south leg at the west ramp. Much of that traffic is <br />already included in the ramp inter section volumes as through vehicles to and <br />from the west. <br />3. There is only one ramp intersection with this design. <br />4. The east ramp volume to capacity ratio is the sum of the eastbound through and <br />the northbound right-turn volumes. For Alternate 7, 3 eastbound lanes are <br />assumed. <br />5. This is the volume to capacity ratios for the other conflicting movements at the <br />east ramp intersection during the PM peak hour. <br /> <br />, <br />L____ <br />
