Project Title: Sustainability Data for Making Transportation Improvement Program Investments
Background:
Many state and local transportation agencies are beginning to take sustainability into account
when making program and project update decisions. Transportation decisions are largely driven
by economics and, to a lesser extent, environmental and social factors. Unfortunately, the three
factors of sustainability (environment, social equity and economics) are often presented as
competing factors rather than harmonizing factors in the decision-making process. Having data
and interpretive tools which address all three realms will better ensure balanced decisions and
streamline processes. Most experts agree this is desirable, however agencies are discovering
that it is difficult to quantify the actual effects of these decisions. While most success stories
are anecdotal, it would be better to demonstrate a measurable outcome as a consequence of a
statewide program/project (reduced congestion, decreased fuel use, etc.)
For example, NYSDOT uses a pavement management model/tool to help prioritize statewide
pavement projects based on funding, pavement conditions (i.e. cracking), International
Roughness Index (IRI), and traffic volume. This tool enables managers to make system-wide
economically based pavement preservation decisions. However, a triple bottom line (economy,
environment and social) approach would ensure more sustainable decisions. The challenge is in
determining what data elements are required to measure the affects of programs and projects
on the triple bottom line, and how to weight these factors in decision making.
NYSDOT’s goal is to determine what metrics can be used to better select projects for
sustainable statewide transportation improvement programs and what metrics can be used,
once projects are built, to determine if the projects achieved desired outcomes.
Statement of Urgency:
NYSDOT and other states are in the process of developing their next five-year Statewide
Transportation Improvement Programs (STIPs) and the federal government is asking states to
include livability and sustainability (for example, “Complete Streets” legislation) in selecting,
designing and building these next round of transportation projects. The preliminary program
development phase is the best time to evaluate those factors that affect sustainability. By
articulating decisions and performance measures in terms of sustainability “Triple Bottom Line”
(i.e., economic, social and environmental), state transportation agencies will be better
equipped to make and justify well-informed, fiscally wise, balanced, and socially and
environmentally sound decisions.
Project Objective:
The project objective is to determine what system-wide metrics or combination of metrics can
be used to better select sustainable STIP projects and what metrics can be used, once the
projects are built, to determine if the projects achieved desired outcomes. The project will
include a gap analysis of:
 What are we measuring now that we can use?

What additional information do we need to determine the effectiveness of our decisions
in relation to the Triple Bottom Line?
What data/metrics are best used to show sustainability successes to the public?
What is the relative cost for agencies to collect these additional data elements/metrics?
Relationship to Existing Body of Knowledge:
There are many federal and state laws which regulate how State DOT’s develop their STIPs. This
project is an effort to identify what data NYSDOT already collects and what data NYSDOT needs
to collect in order to support making meaningful sustainable decisions following existing
regulations. While some states have their own infrastructure (pavement & bridge) data
collection processes, currently there is little guidance available as to what data elements
contribute the most to making sustainable transportation decisions. NYSDOT is also aware of a
SCOP Peer Exchange on Metrics, Data and Methods for Incorporating Sustainability in
Benefit/Cost and Return on Investment Calculations that will be held this summer. Peer
exchange meeting results will contribute greatly to this project.
List of Anticipated Work Tasks:
In reference to the three sustainability factors (economic, social and environmental)
 Identify what system-wide data NYSDOT currently collects that can be used to make
sustainable transportation program decisions.
 Perform a survey of other states and transportation agencies to identify what additional
data they collect that NYSDOT currently does not that can be used to better make
sustainable transportation program decisions.
 Produce a final report to include the following items:
o A nation-wide state-of-the-practice synthesis on what data state transportation
agencies are using to make sustainable STIP project selections and what are the
associated data collection costs.
o A discussion of what data states collect, use and how effective this data is in
measuring program and project sustainability outcomes in terms of the three
sustainability factors, and associated data collection costs.
o Identify additional data that agencies may consider collecting in order to
measure the effect STIP projects have on supporting a sustainable society.
Estimate of Funds Needed:
Estimate will need $98,000.
Estimate of Time Needed to Complete the Research:
Estimate will need eight months to one year to complete this project.
