LTPP 1999: A Year in Review at 2000 TRB Annual Meeting
The annual meeting of the Transportation Research Board (TRB), to be held
in Washington, DC, next month, will include a special session on the status
of and plans for the long-term pavement performance (LTPP) program. The
session, scheduled for 8:00 a.m. on January 10, 2000, at the Marriott
Wardman Park Hotel, will feature four presentations.
- Charles Churilla of the Federal Highway Administration (FHWA) will
lead off with "LTPP in 1999: The Year in Review," which will
highlight the data resolution process, an exhaustive effort to determine
the availability and validity of the program's test sections and their
data. This task, concluded in 1999, "has led to an emphasis on
doing a better job with SPS [specific pavement studies] traffic data,"
said Churilla.
- Michael Murphy of the Texas Department of Transportation will discuss
"Planning for LTPP Data Analysis." His remarks will center
on the development of the LTPP Strategic Analysis Plan Objectives-both
its contents and the process of producing it, from brainstorming by
an expert task group in May 1999, through development, to its eventual
adoption as the guide for LTPP analysis.
- Michael Darter of ERES Consultants will speak on "Making Pavements
Better: Significant Findings from LTPP Data Analysis." The LTPP
analysis studies, which began under the Strategic Highway Research Program
(SHRP) in 1990 and have continued under FHWA since 1994, have served
as an invaluable information source for understanding how pavements
perform. Darter will highlight this wide-ranging topic, using the document,
"Findings from LTPP Data Analysis Studies, Summary List 1990-1999."
- Monte Symons will focus on "They're Putting the Data to Work:
An Overview of LTPP Data Usage." His presentation will cover the
DataPave 2.0 software, among other examples. DataPave 2.0 provides two
to three times the amount of data contained in the previous version
and includes functional enhancements.
LTPP and other SHRP-related activities will also be covered at the SHRP/LTPP
coordinators meeting on January 9. For more information on the coordinators
