Table 125 provides the average hourly conflict counts for all 83 intersections in the field validation study, based on five, 1-hour simulation runs. The counts in table 125 represent the average hourly values in terms of total conflicts and conflicts by maneuver type. Average values (taken over all intersections) are listed at the bottom of the table.
