The comparison of the average IATs calculated using the IAT distribution values and hourly vehicle count values are given in Table 7. The average IATs based on volume were calculated by dividing 1 hour (3600 sec) time period by the number of vehicles per hour counts. The results showed that there was a time difference between the average IATs with a range of m 5%. The average IATs based on hourly traffic volumes were divided by the average IATs calculated using the IAT distribution and a correction factor for the distribution IATs were generated for different number of vehicles per hour values. Then these correction factors were used to adjust the IATs given in Table 5 and Table 6 for each cumulative percentage value. Using the correction factors a table of corrected IAT distribution at cumulative percentile levels as a function of hourly traffic counts for driving lane and passing lane were calculated. It was assumed that the distribution shape remains the same, but the IATs at given percentages need to be adjusted to a value that the mean concise with the hourly rates. The corrected IATs are given in Table 8 for driving lane and in Table 9 for passing lane. 34 Table 7: Comparison of Average IATs Generate...
