Guide to Calculating Mobility Management Benefits Victoria Transport Policy Institute
Economic Development Impacts Economic development refers to progress toward a community’s economic goals, including productivity, employment, incomes, community redevelopment, property values, and tax revenues. Mobility management supports economic development in various ways, reducing transportation costs, improving education and employment access, reducing community expenditures on imported resources (particularly vehicle fuel), and supporting specific industries such as tourism. Many of these are indirect effects of other mobility management benefits, such as congestion reduction, energy conservation and smart growth land use.
Economic Development Benefits Subcategories
Increased economic productivity (employment, incomes, business activity and tax revenue).
Increased property values.
Conventional transport planning tends to consider some economic development benefits, such as industrial expansion, but overlooks others, such as the regional employment impacts of consumer transportation expenditures. Some of these benefits can be monetized using standard economic evaluation tools such as input/output tables and property value studies. Many communities have economic development objectives which can be referenced when evaluating these benefits.
Non-Linearities Under certain circumstances, modest changes in vehicle travel can provide large benefits. For example, once roadways approach their capacity, small reductions in traffic volumes can substantially reduce congestion impacts, providing large benefits to all travelers. Reducing peak period parking demand, for example, if stores encourage employees to use alternative commute modes during busy shopping days, or downtowns offer special bus services during special events, can substantially reduce the number of parking spaces that would otherwise be needed. Even small reductions in high-risk driving, for example, by adolescent males and inebriated drivers, can provide relatively large crash reductions. Since motor vehicles have high fuel consumption and emission rates during short trips, shifting from automobile to non-motorized modes for short trips can provide proportionately large energy savings and emission reductions.
As a result, mobility management benefits are often proportionately larger: for example, a relatively small mode shift can provide large reductions in traffic congestion and parking costs if it involves peak-period trips on major corridors, and shifting a relatively small portion of total travel from motorized to non-motorized modes can provide large reductions in energy consumption, pollution emissions and consumer costs.
