Geh - Applications

Applications

The GEH formula is useful in situations such as the following:

• Comparing a set of traffic volumes from manual traffic counts with a set of volumes done at the same locations using automation (e.g. a pneumatic tube traffic counter is used to check the total entering volumes at an intersection to affirm the work done by technicians doing a manual count of the turn volumes).
• Comparing the traffic volumes obtained from this year's traffic counts with a group of counts done at the same locations in a previous year.
• Comparing the traffic volumes obtained from a travel demand forecasting model (for the "base year" scenario) with the real-world traffic volumes.
