Field Evaluation of Detection-Control System

APPENDIX A: PARTIAL FULL-DAY RESULTS

Table 49, table 50, table 51, and table 52 provide partial summaries of red-light runners and vehicles caught in the dilemma zone prior to converting to the regression analysis approach. These data are not corrected for exposure or other factors as the regression results are. Shaded cells indicate days not evaluated at the point that the procedure changed. Only the two Illinois sites have full days of dilemma zone results for phases 2 and 6, whereas all four sites show most of the red-light running results.
