MTO Environmental Sustainability & Transportation 3 — Questions and Answers
Question 1: What is the environmental advantage of permeable pavement over traditional asphalt?
- It lasts longer and requires less maintenance
- It allows stormwater to infiltrate the ground, reducing runoff and pollution (Correct answer)
- It reflects more sunlight to reduce heat
- It produces less noise from vehicle traffic
Correct answer: It allows stormwater to infiltrate the ground, reducing runoff and pollution
Permeable pavement allows rainwater to pass through to the soil below, reducing stormwater runoff that carries pollutants into waterways.
Question 2: What does 'complete streets' policy mean in the context of sustainable transportation?
- Streets that are fully paved with no potholes
- Roads designed to safely accommodate all users including pedestrians, cyclists, and transit riders (Correct answer)
- Highways with full median barriers
- Streets with complete signage and lighting systems
Correct answer: Roads designed to safely accommodate all users including pedestrians, cyclists, and transit riders
Complete streets are designed to enable safe access for all users regardless of age or ability, encouraging walking and cycling instead of driving.
Question 3: Which type of transportation fuel produces the most carbon dioxide (CO2) per unit of energy when burned?
- Natural gas
- Diesel
- Gasoline
- Coal-derived liquid fuel (Correct answer)
Correct answer: Coal-derived liquid fuel
Coal-derived liquid fuels have the highest carbon intensity, producing more CO2 per unit of energy than conventional gasoline or diesel.
Question 4: What environmental issue does 'anti-idling' policy for trucks and buses primarily address?
- Excessive fuel costs for fleet operators
- Air pollution and greenhouse gas emissions from unnecessary engine operation (Correct answer)
- Noise complaints from nearby residents
- Mechanical wear on vehicle engines
Correct answer: Air pollution and greenhouse gas emissions from unnecessary engine operation
Anti-idling policies reduce air pollutants including particulate matter, NOx, and CO2 emitted when vehicles run their engines while stationary.
Question 5: What is 'induced demand' and why is it a sustainability concern in transportation?
- Higher demand for electric vehicles when gas prices rise
- New road capacity attracts more drivers, negating congestion relief and increasing total emissions (Correct answer)
- Government policies that force drivers to change routes
- Rising fuel costs that reduce overall travel demand
Correct answer: New road capacity attracts more drivers, negating congestion relief and increasing total emissions
Induced demand describes how expanding road capacity attracts new vehicle trips, often filling new lanes quickly and resulting in no long-term congestion reduction while increasing total emissions.
Question 6: What role does transit-oriented development (TOD) play in reducing transportation emissions?
- It mandates electric vehicles near transit stations
- It concentrates housing and jobs near transit hubs to reduce car dependency (Correct answer)
- It builds charging stations along transit corridors
- It requires transit agencies to use renewable energy
Correct answer: It concentrates housing and jobs near transit hubs to reduce car dependency
TOD places housing, retail, and employment near transit stations so residents can meet daily needs without driving, reducing vehicle miles traveled and emissions.
Question 7: How does the Federal Highway Administration's INVEST tool support sustainable transportation?
- It manages federal highway funding allocations
- It provides a sustainability rating system for evaluating highway projects and programs (Correct answer)
- It tracks vehicle fuel economy across the US fleet
- It monitors bridge safety and structural integrity
Correct answer: It provides a sustainability rating system for evaluating highway projects and programs
INVEST (Infrastructure Voluntary Evaluation Sustainability Tool) is an FHWA tool that helps transportation agencies self-evaluate sustainability performance across planning, design, and operations.
