It is agreeable to choose an hourly volume for design, which is about 50 percent of the volumes expected to occur during the few highest hours of the design year, whether or not that volume is equal to the 30th highest hourly volume.

Traffic volume studies are used in traffic engineering to analyze traffic patterns and trends. 

Traffic volume studies are conducted to:
Determine the number, movements, and classifications of vehicles at a given location
Identify critical flow time periods: Determine the influence of large vehicles or pedestrians on vehicular traffic flow
Document traffic volume trends : Traffic volume is defined as the number of vehicles or people that pass a point on a transportation facility during a specified time period.

Traffic volume studies can help with planning one-way streets and other regulatory measures. For example, pedestrian traffic volume studies can be used for planning sidewalks, crosswalks, subways, and pedestrian signals. 

Traffic engineers can use Doppler frequency shift from moving objects to determine speed very accurately. They can also use laser systems that work in day and night conditions.
