Transportation Network: System of interconnecting nodes and links that represent intersections of roadways, railroads, transit lines, or other forms of transportation systems.

Solves transportation network analysis problems using the ArcGIS Network Analyst extension
Requires a network analysis layer referencing a network dataset
Value within a transportation network
Special values: sites for transmission towers, runways, and so on
Prioritization uses a "Score" ...
Typical analytical transactions within Transportation Networks: Modifying direction and/or impedance along links and through intersections. Identifying the optimal path as measured between two or more points according to a selected terms of measurement.
Using a GIS and digital versions of the 1:100,000 - scale ~, political boundaries, and hydrographic features, cartographers produced a 1:500,000 - scale standard base map of New Jersey.
If spatial technologies, as defined in the call for papers for this conference, include new ~s, comunication, and information technologies, then the concept of accessibility needs to be redefined both conceptually and operationally.
When using such maps, we are primarily concerned with how to get from one stop to another along a ~. Certain rules also govern how we can travel along the network (e.g.
Examples include a street in a ~ and a pipeline in a sewer system. In a geometric network, a network edge can be simple or complex. A simple edge is always connected to exactly two junction features, one at each end.
Network datasets are well suited to model ~s. They are created from source features, which can include simple features (lines and points) and turns, and store the connectivity of the source features.
~ with the estimated travel speeds for types of road.
Locations of universities where our guests may be staying.
Locations of Bakeries and Doughnut Shops that we may visit during a sledding break.
Downtown Landmarks that would provide a nice view while we are sledding.
For example, a single layer may represent a group of surface water sampling points, a ~ (lines), a group of forest stands (polygons), or a digital elevation model (raster).
No matter how large or small your community, planners must deal with spatial information: parcel, zoning and land use data, addresses, ~s, and housing stock.
The rapidly growing population of the state is straining all of its ~s. A regularly recurring issue in California politics is whether the state should continue to aggressively expand its freeway network or concentrate on improving mass transit networks in urban areas.
Hierarchy can be used during network analysis to assign priority to a network element. For example, in a ~ dataset, a "road class" hierarchy can be assigned to edges to favor major roads instead of local streets.

Using GIS, emergency management personnel can evaluate a variety of data layers, including elevation, storm characteristics (strength, speed, direction), land use information, population distribution, and ~s to identify the areas that may be inundated by the storm surge, ...
In the process of responding to the demands of society, over the centuries people have unknowingly
created spatial structures, which in turn have modified the environment. (Unplanned ~s are one example of such structures.) ...
