An Introduction to Smart Infrastructure


Quiz Questions

1. Smart infrastructure is best described as:
Physical assets combined with sensing, communications, and data-driven decision-making
A single vendor product installed once and left unchanged
2. In transportation, the highest value typically comes when subsystems:
Share data and support coordinated operations
Operate independently with no interfaces
3. A Traffic Management Center (TMC) is primarily:
An operational hub for monitoring and managing corridors
A pavement materials testing laboratory
4. A connected corridor commonly includes:
Field devices, communications, and center operations tools
Only widened lanes and new pavement markings
5. Structural health monitoring (SHM) is intended to:
Support maintenance decisions and risk reduction
Replace all required bridge inspections
6. Data quality checks can include:
Monitoring missing data and time synchronization
Ignoring sensor failures to avoid alarms
7. A practical cybersecurity step for field devices is:
Network segmentation and controlled remote access
Using shared passwords for convenience
8. Reference-architecture concepts are useful because they:
Provide a common language for subsystems and information exchanges
Mandate a single brand of controller
9. RWIS is mainly used to:
Measure road-weather conditions to support operations
Increase lane width without construction
10. Smart infrastructure projects are more likely to succeed when agencies:
Plan for operations and maintenance over the life cycle
Budget only for construction and skip training
