We all remember this chart Arterials ( Rural/Urban)
higher mobility
low degree of access
Collectors (Rural/Urban)
balance between mobility and access
Locals (Rural/Urban)
lower mobility
high degree of access

What’s that Chart got to do with Me?
• Characterize the Roadway and Land Use
– Cars
– Cars & Trucks
– Cars/Trucks/People
– Cars/Trucks/People/Farms & Ranches/Industry/Zoning
– Cars/Trucks/People/City Life/Industry/Zoning

Designing for the Facility
• Identify Design Controls – Functional Classification
– Terrain
– Location ( Rural/Urban-mixed)
– Traffic Volume
– LOS
– Design Driver and Vehicle
• Speed
• Project Type – New Construction
– Reconstruction of Existing
– 3R ( Resurfacing, Restoration, & Rehabilitation

Are we to smart for our own good?
• The Engineers Trap.
– We really want to help!
– We think we can solve everything!
– We think we can design a solution right away!
• Do our stakeholders really what us to help that much?
– Stakeholders want to be heard!
– Stakeholders want to understand why we design the way we do!
– This doesn’t mean giving up responsible engineering charge!

Which brings us to the Question: When is the right time for choosing Higher or Lower Design Standards?
Chris, would you like to fill us in?
