Nevada Enhances Roadway Network Data With Intergraph Solution The Challenge:

Improving the safety of the state’s highways is a top priority for the Nevada Department of Transportation (NDOT). A crucial step toward that objective is gaining a clear and current view of the roadway network. This isn’t always easy as new roads are built, and old roads are realigned, destroyed, or abandoned. The Department’s Safety Engineering Division tracks more than 60,000 crashes each year, which results in a constant stream of data associated with its road network, commonly called event data. NDOT wanted an information system that could integrate event data and build an up-to-date model of the roadway network. A system with a maintenance environment would enable the agency to have a current data model, track changes as they happen over time, and use this temporally enabled network to facilitate the analysis of event data.

The Project Objectives:

Develop a workflow capable of maintaining NDOT's LRS data
Build new baseline datasets for state and county information
Enhance data maintenance software tools
Simplify data collection

The Solution:

Already an Intergraph® customer, NDOT selected the “GeoTrans” Transportation Data Model – the company’s Multilevel Linear Referencing System (MLRS) and a foundational component of Intergraph’s Roadway Information Management Solution, to develop a temporally integrated linear referencing system and a safety analysis system. The solution uses the advanced MLRS functionality of GeoMedia® Transportation Manager and integrates it with the temporal aspects of GeoMedia Transaction Manager. The MLRS network seamlessly manages all of NDOT’s roadway information, including state and county data from various sources. Regardless of the source, the solution can edit, update, or replace datasets.
