Power moves : Houston, Texas and the politics of mobility, 1950-1985

This dissertation argues that between 1950 and 1985 a diverse collection of residents from the Houston, Texas metropolitan area used debates about the planning, construction, and meaning of transportation structures—primarily highways and mass transit systems—as opportunities to claim political power and to influence the future of their neighborhoods and city. As they contested these systems, Houstonians articulated competing notions of the politics of mobility. In addition to concrete political decisions about transportation, this term also encompasses the daily transportation decisions of Houstonians and the meanings those residents ascribed to the infrastructure that carried them across the city. The politics of mobility uniquely illuminates the intersection of politics, culture, and urban development in Houston. Who wielded the power to make choices about Houston’s transportation networks and how the balance of that power changed over time are central questions of this dissertation. Until the late 1950s and early 1960s, a collection of nearly all white and male elected officials, professional planners, and private developers held immense power over the city’s decision-making process, but never completely controlled it. The actions of citizens outside that group forced leaders to acknowledge, if rarely embrace, the perspectives that citizens held about transportation and the politics of mobility. By the mid-1970s, aided by changes in federal oversight and citizen participation regulations, as well as by their own assertions of political power, an increasingly diverse set of Houstonians—African American, ethnic Mexican, and white, urban and suburban, rich and poor—possessed more influence over the city’s transportation choices. By engaging in these debates, Houstonians challenged the city’s racial, economic, and decision-making status quo. The choices made in Houston’s struggle over the placement of highways and the creation of a public transit authority sheds light onto the foundations of Houston’s unique built environment and offers a model for understanding similar forces at work in other auto-centric southern and western, “Sunbelt” cities, such as Los Angeles and Atlanta. Further, these conflicts illuminate why older cities in the Northeast and Midwest and younger ones in the West and the South developed such divergent urbanization patterns and transportation practices.Histor

Multi-Agent Systems for Transportation Planning and Coordination

Many transportation problems are in fact coordination problems: problems that require communication, coordination and negotiation to be optimally solved. However, most software systems targeted at transportation have never approached it this way, and have instead concentrated on centralised optimisation. Multi-agent systems (MAS) are a different approach to building software systems. Such systems are assembled from autonomously interacting agents; agents are small software programs, which have some type of intelligence and individual behaviour. Communication and coordination (between agents) are the essential elements in the construction of MAS. The transportation domain is often referred to as a potential candidate for the application of MAS. In this dissertation, we discuss two MAS design cases related to the transport of containers. Both cases resulted in concrete prototypes, which let us evaluate a series of aspects important in applying MAS in transportation. We demonstrate the importance of a multi-method validation and evaluation approach. The prototypes were furthermore utilised as artefacts to discuss eventual implementation with future users and experts. One of our most important observations is that planning, as a function within supply chains, is about to go through a fundamental change. Like the mobile phone changed the way people coordinate in daily life, the concepts discussed in this dissertation have the potential to fundamentally change coordination in supply chains. As part of this fundamental change, a different perspective on certainty and uncertainty is essential

Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse
