APPENDIX B. SITE DATA TABLES AND FIGURES
In this appendix are the data tables and figures for each site. Each curve has three tables and two figures representing the data collected during the "before" and "1 month after" periods. The first two tables are the speed statistics collected at the PC and CC. The statistics compare the before data to 1 month after, with a negative change representing a reduction. The fraction of vehicles exceeding the speed limit change shows a percentage change in the vehicles exceeding the speed limit between the data collection periods. Also in those tables are speed statistics using the tracking methodology described in the literature review. The third table contains the statistics collected from the tracking methodology and shows the speed reductions that occurred from upstream to the respective point in the curve.
The figures are graphical representations of the data shown in the tables. One figure shows the vehicles mean and 85th percentile speeds at the data collection points, while the other figure shows the change in vehicles exceeding the speed limit at the data collection points.
