Average Travel Speed

Average travel speed measures the speed at which motorists travel a section of the roadway during a specific time period.

In general, the average travel speed has remained relatively stable over the years. Average travel speed during peak hour slowed by 2.2% from 2014 to 2019. From 2018 to 2019, it decreased by 2.7% statewide during peak hour.


Methodology: Average Travel Speed

The length of the highway segment divided by the average travel time of all vehicles traversing the segment, including all stopped times. Average travel speed is the average of all hourly segment travel speeds captured by probe data or modeled through speed-volume functions.
