AICP Transportation and Infrastructure Planning 4 — Questions and Answers
Question 1: A city is evaluating a Bus Rapid Transit (BRT) corridor. Which feature MOST distinguishes true BRT from an enhanced local bus service?
- Dedicated lanes with proof-of-payment fare collection (Correct answer)
- Larger buses with air conditioning
- Extended service hours on weekdays
- GPS tracking and real-time arrival displays
Correct answer: Dedicated lanes with proof-of-payment fare collection
True BRT is defined by physically dedicated running ways and off-board fare payment, which together provide reliable speed comparable to rail.
Question 2: Under the Americans with Disabilities Act (ADA), what is required of public transit agencies when fixed-route bus service is provided?
- Complementary paratransit service within 3/4 mile of each fixed route (Correct answer)
- Door-to-door service for all disabled residents citywide
- Free transit passes for all ADA-eligible riders
- Dedicated accessible vehicles on every route at all times
Correct answer: Complementary paratransit service within 3/4 mile of each fixed route
ADA mandates that agencies operating fixed-route service must provide complementary paratransit within 3/4 mile of each route and during the same hours.
Question 3: A planner is conducting a traffic impact analysis (TIA) for a new regional mall. Which metric is MOST commonly used to measure intersection performance?
- Level of Service (LOS) (Correct answer)
- Vehicle Miles Traveled (VMT)
- Peak Hour Factor (PHF)
- Annual Average Daily Traffic (AADT)
Correct answer: Level of Service (LOS)
Level of Service (LOS) grades A through F quantifies delay and congestion at intersections and is the standard TIA performance measure.
Question 4: Which federal program provides formula-based funding to urbanized areas with populations over 200,000 for transit capital and operating assistance?
- Section 5307 Urbanized Area Formula Grants (Correct answer)
- Section 5310 Enhanced Mobility for Seniors
- TIGER Discretionary Grants
- CMAQ Congestion Mitigation Program
Correct answer: Section 5307 Urbanized Area Formula Grants
FTA Section 5307 distributes formula funds to urbanized areas over 200,000 population for broad transit capital and operating needs.
Question 5: A Transportation Systems Management and Operations (TSMO) strategy differs from traditional capacity expansion primarily because it:
- Optimizes performance of existing infrastructure without adding lanes (Correct answer)
- Focuses on constructing new interchanges at bottleneck locations
- Prioritizes freight movement over passenger vehicles
- Requires environmental impact statements for all projects
Correct answer: Optimizes performance of existing infrastructure without adding lanes
TSMO improves efficiency, safety, and reliability of the existing network through technology and operations rather than physical expansion.
Question 6: When applying the Highway Capacity Manual (HCM) methodology, 'saturation flow rate' refers to:
- The maximum number of vehicles that can pass a stop line per hour of green time (Correct answer)
- The total volume of vehicles entering an intersection per day
- The ratio of actual volume to roadway capacity
- The time required to clear a queue at a signalized intersection
Correct answer: The maximum number of vehicles that can pass a stop line per hour of green time
Saturation flow rate is the maximum throughput of an approach lane measured in vehicles per hour of effective green, assuming continuous demand.
Question 7: A Vision Zero policy framework adopted by a city is PRIMARILY aimed at:
- Eliminating all traffic fatalities and serious injuries through a systems approach (Correct answer)
- Reducing overall vehicle miles traveled by 20% within five years
- Achieving zero greenhouse gas emissions from the transportation sector
- Ending all at-grade rail crossings within the municipality
Correct answer: Eliminating all traffic fatalities and serious injuries through a systems approach
Vision Zero treats traffic deaths as preventable and uses engineering, education, and enforcement together to achieve zero fatalities and serious injuries.
