For a high range a 25% reduction in spaces is <br /> assumed. <br /> • Low range % VMT Reduction = [(100 - 95)/100] * 0.5 = 2.5°/a <br /> • High range % VMT Reduction = [(100 - 75)/100] * 0.5 = 12.5% <br /> Preferred Literature: <br /> To develop this model, Nelson\Nygaard [1] used the Institute of Transportation <br /> Engineers' Parking Generation handbook as the baseline figure for parking supply. This <br /> is assumed to be unconstrained demand. Trip reduction should only be credited if <br /> measures are implemented to control for spillover parking in and around the project, <br /> such as residential parking permits, metered parking, or time-limited parking. <br /> Alternative Literature: <br /> • 100% increase in transit ridership <br /> • 100°/a increase in transit mode share <br /> According to TCRP Report 95, Chapter 18 [2], the central business district of Portland, <br /> Oregon implemented a maximum parking ratio of 1 space per 1,000 square feet of new <br /> buildings and implemented surface lot restrictions which limited conditions where <br /> buildings could be razed for parking.A "before and after" study was not conducted <br /> specifically for the maximum parking requirements and data comes from various <br /> surveys and published reports. Based on rough estimates the approximate parking ratio <br /> of 3.4 per 1,000 square feet in 1973 (for entire downtown) had been reduce to 1.5 by <br /> 1990. Transit mode share increased from 20% to 40%. The increases in transit ridership <br /> and mode share are not solely from maximum parking requirements. Other companion <br /> strategies, such as market parking pricing and high fuel costs, were in place. <br /> Alternative Literature Sources: <br /> [1] TCRP Report 95, Chapter 18: Parking Management and Supply: Traveler Response <br /> to Transportation System Changes.
