This document discusses sustainable transportation and green roads. It defines sustainability and explains that green roads is a rating system that awards points for sustainable choices in road projects. Key areas for developing green roads are discussed, including watershed-driven stormwater management, recycling and renewables, conservation and ecosystem management, and reducing lifecycle energy and emissions. Specific sustainable practices are outlined for each area, such as using natural stormwater treatment methods, incorporating recycled materials that provide cost benefits, and providing wildlife crossing structures to reduce animal vehicle crashes. The overall goal of green roads is to distinguish more sustainable new or redeveloped roads through this rating system.

3. Sustainability:- is a system characteristic which refers to
the system’s capacity to support natural laws and human
value.
Sustainability can be :
Measured
Judged
Managed
Improved

4. Green roads:- is a rating system designed
to distinguish more sustainable new or
redesigned/rehabilitated roads. It awards
points for approved sustainable
choices/practices and can be used to certify
projects based on point value

6. 1- Environment sustainability

7. 2-Sustainable communities

8. 3-Sustainable Economy

11. Sustainable development Indicator
They are:
• economic output.
• Investment
• employment
• climate change
• air quality
• road traffic
• land use
• waste

13. Watershed Driven
storm water management
divert and treat storm water runoff
Natural treatment method also reduce peak flow
into streams and reduce scouring

14. Energy and Emission Reduction
Energy
Given projected cement production, using 50% fly
ash can save the equivalent energy in 6.4 billion
gallons of gas annually.
Emissions sets a standard to mitigate congestion.
2.9 billion gallons of gas was wasted due to vehicles in
congestion in 2007.

15. Recycle reuse and use renewable
 Many recycled/renewable materials produce a cost benefit.
 Extensive studies have been implemented.
– 2004 to 2005 study showed
Avoided equivalent CO2 emissions of 4.2 million tons
Water savings over 55 million gallons

16. Conservation and Ecosystem Management
 Provide animal crossing structures.
 Wildlife buffer zones
 Reduce animal vehicle crashes by 97%
