Speed Limit Considerations

•Driveways and access (access management strategies will be implemented) •Functional class of roadway (arterial per Tucson MSR Plan but walkable & bikeable per GPs)

•Parking (no parking on arterials)

•Signals (7 signals in 5 miles)

•Pedestrian activity (pedestrian & bike friendly)

•Development (residential & mixed use)


	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.
