Louisiana Department of Transportation and Development Provides Reduced Data-collection Costs to Local Agencies While Ensuring Data Consistency
In an attempt to streamline the data collection process and reduce costs, Louisiana Department of Transportation and Development has encouraged local agencies and metropolitan planning organizations (MPOs) to join a larger statewide data collection effort.
Integrating Safety Analysis in Project Development in Louisiana
Through this effort, LADOTD increased safety awareness throughout the Department and with local agencies. Cost savings, though difficult to precisely quantify, improved the State's ability to use available funding for safety improvement in multiple contexts, and resulted in successful implementation of low-cost alternatives, and reduced crash risk during construction. |

UDOT's Advanced Data Collection Methods Result in Better Quality of Roadway/Asset Data and Improved Internal Management of Data
The data collection effort performed by UDOT was a first-of-its-kind, surveying the entire state roadway network and obtaining a wide set of data elements. LiDAR (a term that combines "light" and "radar") was used by the selected vendor to collect a variety of asset data. The LiDAR technology creates a three dimensional model of the assets scanned along the roadway, and is performed in a single pass at highway speeds. |
