Description:
Speed legends help indicate the speed limit of a roadway. They bring additional awareness where signage may not be posted or where a speed limit change occurs. Field verification is needed to determine if application is justified; no additional data or engineering design is required.
Advantages:
• Heighten awareness of roadway speed limit.
• Low cost and fast to implement.
• Uses a standard traffic control device easily recognizable by motorists.
Disadvantages:
• Requires periodic maintenance/increased maintenance costs.
• Does not physically restrict vehicles from speeding.
• Cannot be used to change a roadway’s speed limit.
• Does not necessarily result in a change in driver behavior.
Suitable:
All Road Types
