“…A planning-oriented example is the use of centrality to qualify nodes in urban transportation networks. Gonçalves et al (2009) have applied this not only to transport network nodes but also to describe access to the surrounding urban area facilities, in order to compare the suitability of the area of influence of different train stations for new developments. A policy-planning oriented example is the use of parameters such as street connectivity by several North American administrations in new urban development review processes.…”

The hypothesis of this paper is that some features of the built environment, particularly those concerned with the accessibility of the street network, could be associated with the proportion of pedestrians on all trips (modal split) found in different parts of a city. Quantitative analysis (bi-variate correlation and a multiple regression model) was used to establish the association between variables. The study area covered a substantial part of the metropolitan area in Madrid, Spain. Results showed a consistent influence of five particular indexes in the multi-variate model. Not surprisingly for this kind of research, four of them described density and mix of land uses. But perhaps more interestingly, the first one was a measure of the accessibility of the public space network, a less prominent variable in literature to date. This variable is called herein configurational accessibility, calculated using Space Syntax, an urban morphology theory. The relevance of configurational accessibility is probably related to its surprising ability to synthesize global and perceived properties of street networks at the same time. The findings introduce the idea that the configuration of the urban grid can influence the proportion of pedestrians (as a part of total trips in any transport mode) who choose to walk on single-journey trips. The discussion links with the current debate about walkability indexes and the need of empirical support for the chosen variables and also with transport planning. Because the relevance of the street network's role is not so easy to grasp, inputs from configurational theory and the pedestrian potential underlying this fact are also discussed at the end of the paper.

Determining the importance of information subsystems is critical to the construction and maintenance of the information systems in manufacturing companies. From the perspective of the interactions among subsystems, several centrality models are developed to assess the importance of subsystems by using software called Code Blocks. A case study is done to test the methods. The results can provide an objective basis for decision making in management activities of an information system, such as information system planning and maintenance, resource allocation and utilization in manufacturing enterprises. The proposed methods will provide new approaches to the quantitative evaluation of the importance of information subsystems.

“…This implies a dark aspect of the Metro network in Seoul-cars have more advantages than the Metro in accessing the CBD. It should be noted that betweenness is known to be an important index to measure the efficiency of transit networks (Goncalves et al, 2009). The straightness index also showed another complication, aside from the incompatibility between Metro and highway networks.…”

Land in the vicinity of railway stations in the Seoul metropolitan area has been spotlighted as a target for redevelopment in accordance with the principles of transit-oriented development (TOD). In order to understand the nature of station areas as a whole, it is required to identify their current status with respect to their built environments, demographic characteristics, socioeconomic status, and transport aspects. Most of the previous studies that have focused on characterizing urban areas assumed that clearly separable clustering is possible and tried to find a robust methodology for that. Many researchers have used either supervised classifiers requiring a pre-classified dataset for training, or K-means-like unsupervised classifiers demanding a predetermined number of clusters. The present study focused on the fact that it was hard to find such a clear separation in station areas in Seoul. A more abstract technology was necessary to position the current status of each station area and to find how different station areas are from one another. A robust unsupervised classifier, called the self-organizing map (SOM), was employed to investigate the similarities and differences among station areas in Seoul. The SOM results revealed many informative findings for policy development without any classification.
