Perhaps knowing more about what you are trying to pull would help us to help you...
"Traffic" is a generic term that can mean Visits or Page Views or Visitors (or even specific actions - i.e. what is the traffic of form submissions - in this case the "traffic" would be successfully completed forms)... there is no specific definition of this.
As @josh__stephens mentioned, you can break out the data by hour, or by minute.. it really depends on what you need. Though I agree with Josh, I usually only look at the data by minute when I am trying to troubleshoot an issue or support an investigation where were really need to dig deeply into what is happening (usually for a specific user to keep the data easier to follow).
Now, I will mention one thing when it comes to "hour" in Adobe... there are actually two dimensions that you can use.
- Hour - this is a unique hour based on a specific date (i.e. 18:00 2023-12-28 - this will represent data collected on Dec 28th between and including 6:00:00 PM and 6:59:59 PM)
- Hour of Day - this will collapse all data within your report range to a specific hour of the Day (6:00 PM - this will represent all data in your range, let's assume the last 7 Full Days that occurred between and including 6:00:00 PM and 6:59:59 PM - so Dec 22 AND Dec 23 AND Dec 24 AND Dec 25 AND Dec 26 AND Dec 27)
Hour of Day is really good at seeing what hours of the day average out to the highest traffic times that your site has, or just to create segments to limit data to "Core Business Hours" or maybe only during a "Flash Sale", etc)
