  7. One Month Progress • 9 March 2010 • 791 actual signalized intersections • actual signal timings • 49 actual counts (FAST) • Avg. Travel Time: 14.37 min (before calibration) • 26 / 49 of link counts within the 15% range (53 % within range) preliminary calibration • 8 April 2010 • 791 actual signalized intersections • actual signal timings • 62 actual counts (FAST) • Avg. Travel Time: 11.18 min (after calibration) • 52 / 62 of link counts within the 15% range (84 % within range) after Calibration

  8. 53 % of link counts are within the 15% range. FHWA requires 85% 8
