Guide to Calculating Mobility Management Benefits Victoria Transport Policy Institute

Mobility management strategies that reduce vehicle travel tend to reduce transport land use impacts and support strategic land use planning objectives. Land use and parking management strategies, which reduce per capita impervious surface area, are particularly effective at supporting these objectives. Improved walking conditions and reduced traffic speeds also tend to be particularly important for achieving land use planning objectives.

Increases in land use density may increase some costs, particularly unit costs of infrastructure, such as per-mile roadway costs.

Conventional transport planning considers certain land use planning objectives, such as preserving high value ecological and cultural resources (mitigation is often required during transportation facility construction to minimize negative impacts), and some communities have integrated transport and land use plans which give priority to transportation projects that support strategic land use development objectives, but land use planning objectives are often overlooked when evaluating individual transportation policies and projects. For example, many communities have generous road width and parking requirements, and make it difficult for developers to reduce these requirements in exchange for mobility management and parking management programs, although this supports their land use planning objectives.

Although they are difficult to quantify, these land use impacts are often significant in value (Litman 2004). Various studies of the costs of sprawl and benefits of smart growth can provide guidance on measuring these impacts (Burchell, et al, 1998). Some impacts can be measured based on economic saving and benefits, such as reduced stormwater management costs, increased public service efficiency, reduced per capita transportation costs, increased agricultural productivity, and increased nearby property values. Some require public surveys to determine the value that residents place on preservation of cultural resources or improved community cohesion. Some impacts require application of other ecological economics methodologies to determine the value of ecological services and resources.
