NETTCP Environmental Impact & Sustainability in Transportation 3

Question 1

What is a 'complete streets' policy designed to achieve from a sustainability perspective?

Accepted Answer

Creating transportation networks that safely accommodate all users including pedestrians, cyclists, and transit riders

Answer

Complete streets policies design roadways for all users to encourage walking, cycling, and transit use, reducing vehicle miles traveled and associated emissions.

Question 2

Which type of wetland mitigation requires creating new wetland habitat to compensate for unavoidable impacts from a transportation project?

Accepted Answer

Wetland compensatory mitigation

Answer

Compensatory mitigation creates, restores, or enhances wetlands to offset unavoidable losses, following the mitigation hierarchy of avoid, minimize, then compensate.

Question 3

How does converting a congested highway interchange to a diverging diamond interchange (DDI) benefit the environment?

Accepted Answer

It reduces vehicle idling and fuel consumption by improving traffic flow

Answer

DDIs reduce conflict points and improve signal timing, decreasing stop-and-go traffic that causes higher fuel consumption and emissions compared to free-flowing conditions.

Question 4

What is the purpose of an Environmental Justice (EJ) analysis in transportation project planning?

Accepted Answer

To identify and address disproportionate impacts on minority and low-income communities

Answer

EJ analysis, required under Executive Order 12898, ensures transportation projects do not disproportionately burden disadvantaged populations with negative environmental or health impacts.

Question 5

Which sustainable practice reduces the urban heat island effect along transportation corridors?

Accepted Answer

Using high-albedo (light-colored) pavement surfaces and increasing roadside vegetation

Answer

Light-colored pavements reflect more solar radiation and trees provide shade and evapotranspiration cooling, both reducing heat absorption in urban transportation corridors.
