Counts & Crashes

The Traffic Operations division conducts traffic counts to monitor traffic throughout the city. Various types of traffic counts are collected and analyzed, which include turning movement counts and traffic volume counts. Over 1,100 vehicular counts and over 40 turning movement counts are collected annually. Additionally, the division collects crash data for traffic studies.

There are three different map layers for each count or study type. The layers can be viewed together or separately from each other by unchecking other layers. This map is updated monthly.  

Speed Studies

Speeding has become an issue all across the City of Springfield, and beyond.

Neighborhoods may request speed studies, but the City Traffic Engineer has to prioritize the requests based on needs. Some locations do not provide adequate results (such as short segmented streets) and all requests must serve the public as a whole. Often citizens will suggest stop signs or speed bumps to help address speeding. But most of the time, neither is a suitable option. Read more about stop signs and neighborhood traffic concerns.

Speed studies collect multiple measurements:

  • the average speed is based of all collected speeds measured, include those of slow cars that may be turning. This speed is a true average and tends to be a comparably lower number.
  • the fastest recorded speed shows the highest speed recorded during that study. This may or may not have been an emergency vehicle.
  • the 85th percentile speed is the best indicator for traffic speeds. This speed shows the driven speed during free-flowing conditions that the vast majority of motorists travel at, or below.
  • the volume shows the amount of cars that traveled by on an average 24 hour time period, counting traffic in both directions.
