By using attributes encoded in the network data model, such as road type, each segment can be displayed to reflect its importance. For instance, the above cartographic representation of a network data model displays three road classes (highway, main street, and street) differently. Descriptive labels for the most important elements

The above graph represents the basic topology of an urban transport network composed of linked nodes. It has been encoded into a network data model to represent reality as closely as possible, both topologically and geographically. Topologically, each node has been encoded with the connectivity it permits, such as whether

Author: Dr. Jean-Paul Rodrigue Network data models offer a digital representation of transportation networks that can be used for planning, operational and simulation purposes. 1. Nature and Utility Graph theory developed a topological and mathematical representation of the nature and structure of transportation networks. However, graph theory can be expanded

Source: Background image from Google Earth. Kansai International Airport is one of the world’s most expensive civil engineering projects. Terminal 1 and the first runway started operations in 1994. It remains as of 2015 the longest airport terminal in the world. The rail station at Terminal 1 is serviced by

Source: Dallas / Fort Worth International Airport (DFW), Hong Kong International Airport (HKG) and Kansai International Airport (KIX). The three mega-airports show different growth patterns in their passenger traffic. DFW initially grew rapidly, but achieved a peak in the 2000s. This implies that DFW has reached its market potential. A

Large airport facilities (terminals, runways, parking areas, hangars, etc.) require a substantial amount of land, which in itself often leads to a dilemma between proximity to central areas and the availability of land. The above map depicts the world’s largest airport facilities in terms of hectares. This does not imply that

Source: Background image from Google Earth. The Dallas / Fort Worth Airport (DFW) is located about 28 km (20 miles) from the respective city centers of Dallas and Fort Worth. It represents a unique example of airport integration along an urban corridor. The five terminals (A to E) are oriented

Source: Dallas / Fort Worth International Airport (DFW), Hong Kong International Airport (HKG) and Kansai International Airport (KIX). In the 1980s and 1990s, traffic handled by DFW grew rapidly, but peaked in 2000 at just above 60 million passengers and 950,000 tons. Over the next 15 years, little change took

Author: Dr. Jean-Paul Rodrigue Mega airports are emerging as major hubs of global air passenger and freight activity. 1. Mega Airports in a Global World The substantial growth of air travel has been associated with the demand for new airport terminal facilities, particularly in the context where an existing airport
