How are speed limits determined?
City ordinance sets the basic speed limit in Springfield at 30 miles per hour (mph). Motorists are to assume the speed limit is 30 mph unless there are signs posting a different speed limit. Speed limits greater than 30 mph can be set on the major streets by the City Traffic Engineer based on engineering studies that include the following factors:
  • Crash experience
  • Functional classification of the streets
  • Prevailing speed of motorists as determined in a speed study
  • Roadway characteristics including alignment, surface, grade, sight distance, and design speed
  • Roadway development including type of land use, driveway spacing, and parking practice
