APPLICATION OF GEOMETRIC DESIGN GUIDES

The results are discussed of a questionnaire survey of each state requesting information concerning the application of the "Geometric Design Guidelines for Local Roads and Streets, Part I - Rural". Thirty six of 42 states have adopted the guides for use on secondary highways; 6 states have their own design criteria based on the "Geometric Design Standard for Highways other than Freeways, 1969." Observations (made by the states are presented with regard to the following aspects of the "guidelines": design traffic volumes; design speed; sight distance; grades; alignment; travel way crown; superelevation; number of lanes; width of surface, shoulder, roadway; structures; bridges to remain in place; vertical clearance; right-of-way widths; side slopes; horizontal clearance to obstructions; intersection design; traffic control devices; and erosion control. The problem of upgrading previously improved highways in the secondary system is also discussed.
