Appendix A. Description of Canadian Intersections

Table 122 provides a summary description of the geometry and traffic control variations in the 83-interection test set used for validation testing. The rightmost column is labeled K. In the Highway Capacity Manual, K (or the K-factor) represents a ratio of ADT (average daily traffic in vehicles per day) to PHV (peak hour volume in vehicles per hour). This was a conveniently short label for this column; however, it is not entirely accurate. The denominators used to calculate the ratios in the K column are actually AM-peak volumes that were simulated for all 83 intersections. When inspecting these K factors for these intersections, note that many were greater than 24, indicating that the peak morning hourly volume was less than 1/24^th of the daily volume. Thus, the AM peak was evidently not the actual peak hour for many of these intersections.

Table 123 provides the average yearly crash information for all 83 intersections in the field validation study. At least 3 years of data were available for all intersections, though some intersections had more data. The longest data record was 8.25 years. The crash information includes yearly crash counts, crashes counts by maneuver type, and crash counts by severity type.

Table 124 provides the average hourly conflict information for all 83 intersections in the field validation study. All intersection were simulated for five replications, each of 1 hour in duration. The counts in table 124 represent the average hourly values, in terms of total conflicts and conflicts by maneuver type.
