ERD File Builder (6/12/2006) -
The LTPP program has enhanced the DataPave Online Web site with the online application ERD Builder. The application is available through the DataPave online application of LTPP-Products online. The application enables users to download longitudinal road profile measurements for all LTPP sections in ERD file format for data analysis. Developed by the Engineering Research Division (ERD) at the University of Michigan Transportation Research Institute, the ERD format facilitates automated plotting of simulation data, experimentally measured data, and data from various analysis programs.
Visitors to the Web site can list dates when profile measurements are made on LTPP sections along with information on the profile measuring equipment used for each monitoring event. This information permits users to select desired profile data and convert it to standard ERD file format for analysis. The LTPP program believes that allowing real-time export of profile data in ERD format from the most current LTPP SDR will help researchers and pavement engineers make better use of the LTPP database for ongoing and future pavement performance analysis and research.

The LTPP DataPave Online web site is based on the DataPave software originally developed by ERES Consultants. The new online version of the site has improved the original intent of the DataPave software by providing access to more data and more features. It has been developed to address the following two objectives:
|
 |
Visualize - The first objective is to provide middle and upper-level managers and other users with quick, easy-to-use presentations to illustrate the value and potential of LTPP data. |
 |
Tools - The second objective is to provide a user-friendly format for exploring, extracting, and organizing the extensive LTPP data for data analysis. |
