speed: 35 mph (per ITE
Recommended Practice for CSS in Designing Major Urban Thoroughfares for Walkable
Communities)
Target
Speed is the speed at which vehicles should operate on Grant Road
consistent with the level of multi-modal activity generated by adjacent land
uses to provide both mobility for motor vehicles and a safe environment for
pedestrians and bicyclists. The target speed is usually the posted speed
limit.
Design
Speed is the speed that governs certain geometric features such as
horizontal curvature, super-elevation, and sight distance.Design speed is typically higher than the
posted speed limit to result in conservative values for design criteria such
as sight distance or roadway alignment.The ITE Proposed Recommended Practice recommends that the design speed
be 5 mph over the target speed.NOTE:
Consultant team staff report that the ITE Recommended Practice currently in
development will recommend that design speed equal target speed.
