The Mineta
Transportation Institute (MTI) has just released Improving
Transportation Construction Project Performance: Development of a Model
to Support the Decision-Making Process for Incentive/Disincentive
Construction Projects. The research results demonstrate a
methodology for developing an incentive/disincentive (I/D) project
time-and-cost performance prediction model. Jae H. Pyeon, PhD and Taeho
Park, PhD were principal investigators.
This model will assist project planners and managers by providing a
complete picture during the I/D contracting decision-making process of
possible performance outcomes with probabilities based on historical
data. The study was performed by collecting transportation construction
project data from the Florida Department of Transportation. The
researchers then evaluated the data using time and cost performance
indices. Then they performed statistical data analysis to identify
important factors that influence construction project time performance.
¿User-friendly visual interfaces were developed to perform the
simulation and report results using Visual Basic Application
programming,¿ said Dr Pyeon. ¿The developed model was validated using
additional cases of transportation construction projects. Based on
statistical analysis, this research found that several project factors
influence I/D contracting performance.¿
The important factors that had significant impacts on project
performance, he said, were the effects of contract type, project type,
district, project size, project length, maximum incentive amount, and
daily I/D amount. The developed model applied to I/D contracting
projects will be a useful tool to assist project planners and managers
during the decision-making process. It also will promote the efficient
use of I/D contracting, which in turn will benefit travelers by reducing
the longer travel time that comes from construction delays. With
additional project data, the developed model can be updated easily. The
more data used for the model, the better the expected prediction
accuracy.

ABOUT THE MINETA TRANSPORTATION INSTITUTE
The Mineta
Transportation Institute (MTI) was established by Congress in 1991
as part of the Intermodal Surface Transportation Efficiency Act (ISTEA)
and was reauthorized under TEA-21 and again under SAFETEA-LU. The
institute is funded by Congress through the US Department of
Transportation¿s (DOT) Research and Innovative Technology
Administration, by the California Legislature through the Department of
Transportation (Caltrans), and by other public and private grants and
donations, including grants from the US Department of Homeland Security.
DOT selected MTI as a National Center of Excellence following
competitions in 2002 and 2006. The internationally respected members of
the MTI Board of Trustees represent all major surface transportation
modes. MTI¿s focus on policy and management resulted from the Board¿s
assessment of the transportation industry¿s unmet needs. That led
directly to choosing the San José State University College of Business
as the Institute¿s home. MTI conducts research, education, and
information and technology transfer, focusing on multimodal surface
transportation policy and management issues. Visit www.transweb.sjsu.edu
