Peak Hour Measurements: How accurate do data sourcesneed to be?

Overview

This white paper explores the impact of data accuracy on peak hour calculation, seeking to answer the formalized question: what is the probability of a peak hour measurement being correct given that the data used to compute it is only accurate to a certain level?

Read this white paper to learn:

• The probability of a peak hour measurement being correct given different error rates of source volume data
• The connection between this probability and the type of road (total volume, original PHF) that is being measured
