Towards models of strategic spatial choice behaviour: theory and application issues

Models of spatial choice behaviour have been around in geography urban planning for decades to assess the feasibility of planning actions or to predict external (competition) effects on existing destinations. Although these models differ in terms of complexity and key concepts, they all have in common that spatial choice behaviour is predicted as a function of the attributes of the choice alternatives and distance or travel time separation only. None of these models do take into account that the attributes of choice alternatives and travel time may be highly non-stationary and that often the utility that people derive from visiting a particular location also depends on the choice behaviour of other individuals. Under these circumstances, individuals may exhibit strategic choice behaviour. That is, they will choose particular choice options taking into account their expected behaviour of others such as to maximize their own utility. The purpose of the proposed paper is to discuss possible models of strategic choice behaviour for these urban planning problems. Theory will be outlined and some critical issues in the application of such models to problems of spatial choice will be discussed.

Time to leave: an analysis of travel times during the approach and landfall of Hurricane Irma

Hurricane Irma caused widespread evacuation activity across Florida and some of its neighboring states in September of 2017. The researchers gathered estimated travel times from the Google Distance Matrix API over about a month to identify and analyze evacuation periods on roads in Florida, Georgia, and South Carolina during this time. Travel time data were mathematically adjusted to show more realistic estimations. Both sets of travel times were then graphed, with the assumption that elevated travel times prior to and during hurricane landfall were indicative of evacuation activity. The study generally corroborated the well-established daytime evacuation preference. However, not all evacuation periods followed the daytime travel preference, and at least one nighttime evacuation may have been caused by flooding. In another case, later elevated travel coincided with significant power loss. Finally, the Florida data suggest that most of the evacuation traffic departed before local jurisdictions’ recommended evacuation start times.

     

International and domestic tourism: Interfaces and issues

This paper reviews the interfaces between international and domestic tourism and explores a number of associated issues. Within the origin the interface is between domestic tourism and the outbound component of international tourism. Questions arise relating to the different propensities for domestic and outbound travel and reasons accounting for this variation at a national scale — size, national tourist resources and levels of economic development — and at an individual level where motivations and the ability to travel play a major role. Within destinations interfaces exist between domestic tourism and inbound international tourism. Questions there relate to the size and distribution of these two types of tourist traffic, their respective impacts and the interaction between the two groups. Issues raised include those of the substitution of domestic and outbound travel and the formulation of policies whose varied aims are likely to be met by different spatial strategies. Future research needs to examine differences and interactions between domestic and international tourism more fully and explicitly so that more effective policies might be derived.     

State,capital and spaceships: A terrestrial geography of space tourism

Over the past decade, there has been a significant structural and geographical change in space travel. Following policy, budgetary and regulatory changes in the United States, space travel may now be conducted by private companies. This privatization has also led to some geographical competition and shifts between states within the US. In this paper, I respond to MacDonald’s (2007) call for more critical geographies of outer space activity. Building from his suggestion that we look more closely at the ways in which outer space activity is constituted by “numerous familiar operations” with respect to the practices of international relations and war and to the “basic infrastructural maintenance of the state and the lives of its citizenry”, this paper explores why the US Government has allowed for private space travel and why this privatization drove some states in the US to invest heavily in such a nascent industry sector. It argues that federal and state governments both saw private space travel as a means to fulfill their “basic infrastructural maintenance” with regard to economic expansion, development and competitiveness. The paper analyses these processes through the development of space tourism. In doing so, it provides more detail and geographical context to Dickens and Ormrod’s (2007) overview of the connections between outer space and the circuits of capital. It also demonstrates the many familiar political-economic processes involved in the privatization of space travel and, as such, the possibilities for further critical geographies of space activity.
