Guide to Calculating Mobility Management Benefits Victoria Transport Policy Institute
Transportation Diversity Transportation diversity refers to the quantity and quality of accessibility options available, particularly for non-drivers. Improved diversity increases transport system efficiency by allowing users to choose the best travel option for each situation, reduces chauffeuring responsibilities, improves disadvantaged people’s economic opportunities, and increases community resilience. It is the opposite of automobile dependency.
Transportation Diversity Benefits Subcategories
Allow people to choose the travel option (reducing stress and increasing enjoyment).
Reduced need to chauffeur non-drivers.
Financial savings, particularly for lower-income people.
Increased economic opportunity for non-drivers (supports equity objectives).
Increases transportation system resilience (ability to accommodate unexpected and sudden change).
Mobility management generally increases transportation diversity by improving alternative modes and creating more accessible communities. Improvements that accommodate people with disabilities (called universal design) are particularly helpful. Programs that encourage discretionary travelers (people who could drive) to use alternative modes can provide indirect benefits to non-drivers’ by increasing public support for alternative modes and increasing their social acceptability.

This table identifies how various mobility management strategies help increase transport diversity.
Conventional transport planning gives some consideration to the value of maintaining multiple roadway route options and public transit services, but lacks a comprehensive methodology for evaluating transport system diversity. Some transportation diversity benefits can be monetized, including economic benefits from improving mobility for non- drivers, reduced chauffeuring costs, and option value (Forkenbrock and Weisbrod, 2001; VTPI, 2006). Total benefits are the sum of these individual benefits.
