Guide to Calculating Mobility Management Benefits Victoria Transport Policy Institute
Conclusions Mobility Management (also called Transportation Demand Management) consists of various policies and programs that increase transport system efficiency by improving travel options, providing incentives to change travel behavior, and increasing land use accessibility. Mobility management can provide various benefits, including:
Congestion reduction Road and parking cost savings Consumer cost savings
Improved transport diversity Improved traffic safety Energy conservation
Pollution reductions Efficient land use Improved fitness & health
Conventional transport project evaluation methods were designed primiarly to evaluate roadway investments. They overlook many impacts (costs and benefits) resulting from changes in total vehicle travel and mode shifts. As a result, they tend to exaggerate the benefits of automobile-oriented improvements such as roadway capacity expansions, and undervalue mobility management solutions.
This guide describes more comprehensive ways to evaluate mobility management benefits. It discusses ways of predicting how specific strategies affect travel behaviour, and the economic, social and environmental impacts that result. It defines various categories of benefits, describes how they can be quantified and monetized, discusses the degree they are considered in current transport planning, and identifies the mobility management strategies most effective at achieving specific planning objectives.
Many mobility management strategies directly user benefits by improving mobility options and providing financial rewards for reduced driving. In addition, consumers can benefit indirectly through reduced congestion and accident risk to road users, reduced need to chauffeur non-drivers, reduced pollution emissions, increased revenues, and economies of scale in the provision of alternative modes.
Several current trends increase the value of mobility management, including increasing congestion, rising fuel costs to individuals and society, aging population, growing concern over sedentary living, and consumer preferences for more urban living and travel options. Older policies and planning practices that favor automobile-oriented transport and undervalue alternatives are increasingly outdated and inappropriate.
Many mobility management strategies reflect market principles such as efficient pricing and consumer sovereignty, and so tend to increase overall economic efficiency and equity. Critics sometimes argue that mobility management has been tried but failed, or that its costs exceed its benefits, but their analysis tends to overlook many mobility management benefits and the full costs of alternative solutions that increase total vehicle travel. When all impacts are considered, mobility management strategies often turn out to be the most cost effective and beneficial way to improve transportation.
