Information Provided by Freeway Signing

Due to the high-speed and high-volume nature of freeways, freeway signing should strive to provide information in a manner that contributes to quick processing and conveys clear meaning. Key factors to consider include:
  • Freeway signing should provide information to meet the needs of the unfamiliar road users.
  • Freeway signing provides advance information about approaching decision points in a manner that allows adequate time for response at freeway speeds.
  • Freeway signing does not have to identify every possible choice for the driver.
  • Freeway signing may direct the road user along a longer distance route to simplify the guidance information associated with reaching the indicated destination.
