Methodology + factors for mixed-use sites where uses peak at different times → shared demand < sum of individual peaks. Hourly/monthly profiles, modal & non-captive adjustments.
Why: THE defensible basis for shared-parking reductions; many codes reference it by name.
When: any mixed-use parking analysis or shared-use agreement justification.
Example questions:
- office+restaurant+residential — governing hour and month?
- how is non-captive applied without double-counting internal capture?
