In the LOS D peak-hour scenario, the 3,200 drivers take an average of 71 seconds to drive the <br />approaches to the intersection, experiencing an average of 39 seconds of delay per vehicle. <br /> · The average driving speed is reduced to 14 MPH. <br /> · The average driving time increases to 71 seconds. <br /> · The average delay is 39 seconds per vehicle. <br /> · The average traffic backup is eighteen cars long (420 feet). <br /> · The average fuel economy drops to 11.5 miles per gallon. <br /> · The vehicles generate 16.6 pounds of automotive emissions for a base rate of 6.8 tons per <br /> year per 10,000 peak-hour vehicles. <br /> <br />LOS D SCENARIO MODEL SUMMARY TABLE <br /> <br /> Travel Time Delay Time Average Average Total Travel Distance <br /> Number <br /> of Cars per Car in per Car in Speed Traffic Hours of Time Traveled <br /> Seconds Seconds tMPH) Backup Delay (Hours) (Miles) <br />Baseline 30 MPH 900 32 0 30 None 0 8 244 <br />LOS A <br /> 900 40 8 25 18 feet 2 10 244 <br />(30% of Capacity) <br />LOS A/B <br />(54% of Capacity) 1,800 44 12 22 62 feet 6 22 488 <br />LOS B <br /> 2,500 52 20 19 170 feet 14 36 678 <br />(73% of Capacity) <br />LOS C <br /> 2,860 59 27 17 265 feet 21 47 776 <br />(82% of Capacity) <br />LOS D <br />(91% of Capacity) 3,200 71 39 14 420feet 35 63 868 <br /> <br />+12% +20% +43% -18% +67% +34 +12 <br /> <br /> Gallons of Fuel Fuel Economy CO Emissions Nox Emissions VOC Emissions <br /> Consumed (MPG) (Pounds) (Pounds) (Pounds) <br />Baseline 10 24.3 1.54 0.31 0.35 <br />LOSA <br /> 14 17.5 2.14 0.42 0.51 <br />(30% of Capacity) <br />LOS AfB <br /> 32 15.4 4.89 0.95 1.15 <br />(54% of Capacity) <br />LOS B <br /> 49 14.0 7.50 1.46 1.74 <br />(73% of Capacity) <br />LOS C <br /> 60 12.9 9.24 1.81 2.14 <br />(82% of Capacity) <br />LOS D <br /> 76 11.5 11.66 2.27 2.69 <br />(91 aA of Capacity) <br /> <br />+27% -11% +26% +26% +26% <br /> <br />LOS E - 3~450 Drivers Scenario (About 100 Percent of Capaci~, ) <br /> <br />As with the LOS D scenario, at LOS E, small increases in cars result in very significant increases <br />to traffic delays. At LOS E intersections, drivers experience very long traffic backups and <br />usually wait though more than one green light to pass through the intersection. In this scenario, <br />traffic only increases another 250 vehicles per hour or about 11 percent. However, drivers <br />experience a 74 percent increase in delay. This scenario represents mid-level LOS E conditions <br /> <br />13 <br /> <br /> <br />
