Transportation Needs
• Wants
• Needs
• Demand
• Population Based
▫ Number of persons residing in households owning no vehicle +
Number of persons residing in households with income below the poverty line
▫ Data for each group, individually, available from the American Community Survey
Need
• Represents the full unmet trip need relative to those with relatively unfettered mobility
• Since the measure is in trips, it is possible to estimate the number of vehicles and vehicle-miles that would be required to serve the unmet need
• Serving all of the unmet need is unrealistic. This measure can be used to estimate the proportion of unmet need that is served or to set goals based on proportion served
