Guide to Calculating Mobility Management Benefits Victoria Transport Policy Institute

Program Evaluation Whenever possible, mobility management should include evaluation programs in order to determine actual travel impacts and benefits. A typical evaluation program includes collection of statistics on program costs, participation and travel impacts, and participant surveys. Evaluation activities should continue for several years to determine long-term impacts. Finke and Schreffler (2004) describe the following levels of assessment:

  • 1.

    Awareness. Measuring the target audiences’ (residents, business leaders, public officials, etc.) overall awareness of mobility management strategies and programs.

  • 2.

    Attitudes. The degree to which the target audience supports mobility management strategies and programs.

  • 3.

    Participation. The amount that the target audience participates in mobility management programs, such as applying for ridematching services or purchasing discounted transit passes.

  • 4.

    Satisfaction. The degree to which the target audience is satisfied with mobility management strategies and programs, particularly those that they have used.

  • 5.

    Utilization. The degree to which the target audience has changed their travel patterns in response to mobility management strategies and programs.

  • 6.

    Impacts. The degree to which mobility management changes overall vehicle traffic, traffic congestion, road and parking costs, traffic accidents, etc., compared with what would have occurred otherwise.

  • The ratio of automobile and transit travel time for various trips.

  • The ratio of automobile operating costs and transit fares for various trips.

  • The difference is Level of Service ratings for various modes.

  • The relative attractiveness of automobile dependent and transit-oriented locations.

  • The perceived comfort and convenience of various modes.

For most of the last half-century, automobile travel speeds, affordability and comfort have improved relative to transit travel, in part due to public policies such as transportation investment practices that favored highway expansion over transit service improvements, generous minimum parking requirements in zoning codes, low fuel taxes, minimal investment in new transit equipment, and little effort to improve nonmotorized travel conditions. Mobility management includes various strategies that make alternative modes relatively more attractive. Comparisions between modes can help prioritize strategies for achieving mobility management objectives. For example, if commuters are shifting from transit to automobile travel on a particular area, it may be useful to compare automobile and transit travel times, financial costs and comfort factors, in order to identify which of these factors is most responsible, and may be most suitable for change. It may turn out that fare discounts are most effective in some circumstances, while speed improvements are most important in others.
