An Integrated Methodology for Analysing the Acquisition and Use of Mobility Products and Services

Much discussion has taken place in recent years about policies for managing travel demand (principally private car use). Much of this discussion addresses the various negative externalities, such as; congestion, emissions, casualties, etc. Field implementation is frequently costly in one respect or another, therefore, predicting the effects of such policies during the planning stage is one of the challenges that face the transport discipline today. Broadly speaking there are two strategies for regulating car use through travel demand management policies. One can target people’s access to cars, perhaps through measures such as limiting space available for car parking or driver’s licensing/car registration costs. Alternatively, one can address car usage directly, through policies such as congestion pricing, fuel duty, improvements to non-car travel methods, workplace travel planning schemes, restrictions on single-occupant vehicles, etc. Stated another way, the inter-relationships between “strategic” car access issues and “tactical” usage have been recognized for decades, and a set of policies have been proposed in various contexts that rely on influencing this connection. These relationships extend logically to non-car mobility goods as well. For example, public transport season tickets may, for instance, be seen as “strategic” in nature. A person makes a commitment by purchasing a season ticket, which then shapes the set of travel methods available for their use. This paper proposes a novel methodological framework for integrating these two levels of analysis regarding personal mobility, providing a new set of techniques for evaluating proposed policies with potentially subtle or counter-intuitive secondary impacts. In order to accommodate the possibility of complementarity amongst different types of travel methods for performing different kinds of journeys, the authors employ the concept of mobility bundles, sets of one or more travel methods. The proposed techniques are also appropriate for analyzing the introduction of new mobility goods into the marketplace. The substantive context on which this research focuses is the uptake of shared-car services by Londoners. Empirically applying the proposed methodologies requires information on the attractiveness of alternate travel options. The authors report on a web-based technique for synthesizing travel itineraries by various methods of travel, making use of state-of-the-art online travel planning services which are national in coverage.
