Abstract:"The purpose of this study is to review existing Environmental Tracking Systems (ETSs) used by other,
select state Departments of Transportation (DOTs), as well as the existing Environmental Commitment
Tracking System (ECTS) currently in use by Colorado Department of Transportation (CDOT) in an effort
to determine which system would be the most beneficial for long-term implementation at CDOT.
Implementation:
Based on the quantitative evaluation assessing how well other state ETSs’ features correlate to CDOT’s
preferences, this study recommends that CDOT adopt FDOT’s existing ETS for long-term implementation.
Findings based on the Analytical Hierarchy Process (AHP) analysis performed comparing CDOT’s
existing ECTS to eight other state DOT’s ETSs, show that FDOT’s existing ETS supports the highest
number (93%) of CDOT’s weighted preferences, while CDOT’s existing ECTS supports only 35%.
Secondary implementation recommendations are to have a number of CDOT end users familiar with
CDOT’s ECTS test candidate ETSs for ease of use and user satisfaction, and that additional first cost and
operational cost information be secured and analyzed to assist in making a final decision on which system
to adopt. If CDOT elects to implement this second recommendation to further examine additional metrics
prior to making a final decision, VDOT’s and TxDOT’s ETSs are the systems which currently provide the
second (90%) and third highest (85%) number of desired features respectively."
