PDH Quiz - An Introduction to Smart Infrastructure

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
