How much traffic is there?
In Ada and Canyon Counties, most traffic is generated by private vehicles. According to the American Community Survey, over 85% of residents in the area travel to work by auto, and a majority of them (78%) do so by themselves. That’s a lot of cars on the road.
Looking at it another way, over 1.8 million passenger vehicle trips were taken on roadways in Ada and Canyon Counties on an average weekday in 2021. That number is forecasted to increase to almost 3 million by 2050.
All those vehicles lead to congestion: too many vehicles on a portion of roadway at a given time. Congestion can be recurring predictable “rush hour” traffic or non-recurring less predictable delays caused by road construction, traffic crashes, inclement weather, special events, or emergencies.
