GIS for Sustainable Urban Transport [PDF]

ISPRS International Journal of Geo-Information, 2015
The world is urbanizing at a very fast pace. Modern geography, particularly geo-information systems (GIS) and global positioning systems (GPS) are reshaping the way urban and transport planners are collecting, exploring, synthesizing, analyzing, evaluating and presenting their data. [...]

Urban traffic from the perspective of dual graph [PDF]

, 2007
In this paper, urban traffic is modeled using dual graph representation of urban transportation network where roads are mapped to nodes and intersections are mapped to links. The proposed model considers both the navigation of vehicles on the network and

The Rail Surface Defects Recognition via Operating Service Rail Vehicle Vibrations

Machines, 2022
Rail surface defects will not only bring wheel rail noise during train operation, but also cause corresponding accidents. Most of the existing detection methods are manual detection, which is time-consuming, laborious, inefficient, and subjective.

Roadmap to Gridlock: The Failure of Long-Range Metropolitan Transportation Planning [PDF]

, 2008
Federal law requires metropolitan planning organizations in urban areas of more than 50,000 people to write long-range (20- to 30- year) metropolitan transportation plans and to revise or update those plans every 4 to 5 years.
