Boise City, ID Urbanized Area Congestion Report
In the line graphs below, FHWA uses Data Collection Year instead of Data Reporting Year to represent snapshot condition/performance at the time the data was collected. More information
The Boise City, ID Urbanized Area covers parts of Idaho. Targets are agreed upon by several transportation agencies and apply to the entire area.

(Idaho) The Boise area has been the site of tremendous growth in recent years. Over the next performance reporting period, the area will see several major expansion projects at various stages of completion (for example, wrapping up I-84 expansion which is currently creating traffic backups that extend into Ada County as well the construction of SH-16 thru the northwestern part of the urban area). These factors, combined with the fact that Boise only first entered the PHED criteria (and due to AQ rules, may not need to report this after this performance period) is causing us to chose a rather conservative goal with respect to the baseline measure. COMPASS and ITD worked together to come up with this goal.

(Idaho) With a great influx of people moving into the area, many of which are leaving higher population states, there's reason to expect the %non-SOV to go down before it goes back up. However, we expect some ridesharing/transit to improve with the recovery from COVID-19. The COMPASS MPO has on record a target of 25% non-SOV by 2030, so an improvement by the end of this Performance Period is targeted. For the time being, we plan on continuing to use ACS's %SOV measure ("Method A") as our data collection method.
