Who Shifted My Transportation Planning Paradigm? Given by: Ronald T. Milam, AICP Transportation Research Board Planning Applications Conference, May 2007

THE FORCE BEHIND THE SHIFT “The procedures address only local oversaturated flow situations, not systemwide oversaturated flow conditions.” – Page 22-1, HCM 2000

THE PROBLEM WITH TODAY’S PARADIGM Traditional Transportation Planning Process LAND USE PLANNING THRESHOLDS BASED TRANSPORTATIONPLANNING LOS Functional Class Design Standards RECOMMENDED TRANSPORTATION PLAN Sized to Thresholds Process results in a plan that has unknown costs and is unlikely to be fully implemented resulting in traffic operations that will be worse than projected

Placer Parkway CASE STUDY EXAMPLE Originally Identified Based on LOS Thresholds - 1992 Cost Estimate (2006) = $660 Million Projected Available Funding by 2030 = $55 Million Projected Construction Date = Unknown

HOW CAN WE RESPOND TO THE SHIFT? The “New” Transportation Planning Process LAND USE PLANNING CONSTRAINTS BASED TRANSPORTATIONPLANNING Funding Environmental Political RECOMMENDED TRANSPORTATION PLAN Sized to Constraints for design year ROW based on thresholds Feedback Available and Now Justified (if plan is politically unacceptable) Process results in a plan that is consistent with constraints (especially available funding) and provides a realistic assessment of future traffic operations. ROW is still preserved based on thresholds.
