Keeping people and products moving safely, efficiently, and without delay is a complex task – especially with the demand for ever improving service by businesses, the public, and political leaders. Geospatial solutions for road, rail, mass transit, airports, and seaports assist transportation officials to perform the complicated tasks associated with developing and maintaining these systems including inventory, management, and analysis.
Traffic flow modeling is an integral part of advance traffic management in modeling and simulating the flow of both recurrent and non-recurrent traffic. This is done to determine the points of congestion in a current road network and to propose solutions to improve the traffic flow by providing alternative uses of the existing roads and modification of signal timing and road lanes.
A traffic model can be used to simulate planned or proposed changes to an existing road network as well as natural changes in traffic volumes, which accompany growing populations. This type of analysis can be done early in the planning stages of a project to determine how changes to a single road or set of roads might affect the broader transportation network. Geospatial technology is providing the means to more efficiently plan a project and evaluate potential alternatives.
One of the most important safety issues for airfield operations is obstructions to navigable airspace. The Federal Aviation Administration and Department of Defense both have regulations that are very explicit in defining protected airspace and what is considered an obstruction. However, in practice, it has been extremely difficult to accurately and consistently identify airspace obstructions. Geospatial technologies are being used to address this critical issue with higher fidelity and accuracy while minimizing the impact of obstruction removal to the environment.
Can you imagine a more daunting task than relocating a railroad line? Geospatial technology is being used to determine which alternate routes should be used in building the CSX Railroad, which is being relocated away from the congested areas along the Mississippi Gulf Coast. The technology is being used to help assess three potential corridors for the railroad, in terms of hydrologic issues, public safety, economic issues and in particular, the proposed railroad’s potential impact on the wetland habitats that would be affected by the corridors in question.
