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 7
