Guide to Calculating Mobility Management Benefits Victoria Transport Policy Institute

Efficient Land Use Motor vehicle traffic, transportation facilities (roads, parking lots, terminals and airports), and automobile-oriented land use development patterns (commonly called sprawl) tend to impose various undesirable land use impacts, as summarized in Table 13.

Increases costs of providing public services, such as utilities and deliveries.

Increased Transportation Costs

High traffic roads discourage walking and therefore transit.

Wide roads and large parking lots discourage walking, and therefore transit.

Dispersed destinations and reduced transport options reduces accessibility.

This table summarizes categories of transportation land use costs.

Mobility management tends to reduce undesirable land use impacts by reducing motor vehicle ownership and use, reducing the need to expand roads and parking facilities, and supporting smart growth land use policies. Many mobility management programs involve smart growth implementation. In addition to helping to achieve transportation planning objectives, such as reducing accidents and improving mobility for non-drivers, these changes help achieve many land use planning objectives, such as greenspace preservation, urban redevelopment and reduced stormwater management costs.

Land Use Benefits Subcategories

  • Greenspace, farmland, and wildlife habitat preservation.

  • Preservation of cultural resources (historic sites, traditional communities, etc).

  • Redevelopment of existing communities.

  • Increased community cohesion (positive interactions among neighbors).

  • Reduced costs of providing public services.

  • Improved accessibility, reduced transportation costs, improved travel options for non-drivers.

  • Reduced stormwater management costs and heat island effects.

  • More attractive communities, higher property values.
