Travel Time to Work

A multi-lane divided street entering an intersection, traffic lights, several cars approaching the intersection, and a railroad underpass beyond the cars.

What is the indicator?

The first indicator in the Mobility category is the mean, or average, travel time to work for Champaign County residents, compared to the mean travel time to work for the United States and Illinois.

 

What does the data say? Are there any notable trends?

Champaign County’s mean travel time to work is significantly lower than the mean travel time to work in Illinois and the United States. Based on this figure, the state of Illinois has the longest commutes of the three analyzed areas; all three areas show slight and inconsistent upward trends between 2005 and 2015. Champaign County’s mean travel time decreased slightly between 2013 and 2014, but showed an increase of a tenth of a minute, not statistically significant, between 2014 and 2015.

 

Why is this important?/Why did we include it in our set of indicators?

On its own, mean travel time of all commuters on all mode types could be reflective of a number of different conditions. Congestion, mode choice, changes in residential patterns, changes in the location of major employment centers, and changes in the transit network can all impact travel time in different and often conflicting ways. We don’t recommend trying to draw any conclusions about conditions in Champaign County, or anywhere else, based on mean travel time alone.

However, when combined with other indicators in the Mobility category (and other categories), mean travel time to work is a valuable measure of transportation behaviors in Champaign County.

 

Where did we get the data, and how often is it released?

Mean travel time data was sourced from the U.S. Census Bureau’s American Community Survey 1-Year Estimates, which are released annually.

As with any datasets that are estimates rather than exact counts, it is important to take into account the margins of error (listed in the column beside each figure) when drawing conclusions from the data.
