The technology for determining the geographic location of cell phones and other handheld devices is becoming increasingly available. It is opening the way to a wide range of applications, collectively referred to as location-based services (LBS), that are primarily aimed at individual users....

Peering between network providers is modeled as a set of interconnections at hub nodes. The paper employs probabilistic methods to determine the likelihood of a path between nodes, under a variety of simulated disruptions or failures of parts of a network. Reliability is measured as the...

Stereo panoramic virtual reality (VR) may represent another new technology with which to collect travel diaries. The potential value of VR-based systems is that respondents may reexperience and reenact their behaviour. The actual experience and visual trigger may lead to more valid data. To test...

Although the components of plan quality are well defined, little empirical research has been conducted to understand the degree to which policies are being implemented after plan adoption and the factors contributing to the variation in plan implementation. The authors test the efficacy of...

The recent pursuit of regional planning agendas in England has coincided with a strong push from the government towards an evidence-based, information-intensive approach to policymaking, with the increased use of statistical indicators to inform and evaluate emerging regional policies. In this...

The algorithmic design of an architectural configuration depends on one’s ability to compare the merit of different solutions quantitatively, in order to decide which design is superior. We propose a merit function that accounts for the amount of view from a given unit and its accessibility to...

In this paper we revisit the concept of entropy as it manifests itself in spatial terms. We focus specifically on the question of how entropy measures applied to different urban contexts can be adjusted to allow for meaningful comparisons between cities with differing geographic dimensions. It...

In this paper, different land-use planning models have been reviewed; within this review, techniques and methodologies with different objectives, applications, and land uses have been identified. The existing literature in this field is dispersed throughout different subjects, such as planning,...

Humans have evolved in natural environments, a process which has resulted in the development of a neural system specialized in the processing of information about the natural world (for example, plants and animals). To a certain extent, the existence of such a system can explain the perennial...

In this simulation, based on a spatial garbage-can model, I treat the urban dynamic system as a set of random-walk elements interacting with each other in time. Five elements are considered: decisionmakers, choice opportunities, problems, solutions, and locations. Decisionmakers, problems, and...
