Question 1

Which wireless communication standard is most commonly used for vehicle-to-infrastructure (V2I) communication in smart parking systems?

Accepted Answer

DSRC (Dedicated Short-Range Communications)

Answer

DSRC operates in the 5.9 GHz band and is the primary standard adopted for V2I communication including parking guidance and payment systems.

Question 2

A parking facility wants to implement dynamic pricing. Which data input is LEAST relevant to an automated dynamic pricing algorithm?

Accepted Answer

The age of the parking structure

Answer

Dynamic pricing algorithms rely on real-time occupancy, historical demand, and temporal factors—not the physical age of the structure.

Question 3

In a smart parking system, what does 'ground truth validation' refer to?

Accepted Answer

Verifying sensor data accuracy against physical observation

Answer

Ground truth validation involves physically auditing the facility to compare actual occupancy against what sensors are reporting to ensure data accuracy.

Question 4

Which metric best measures the effectiveness of a parking guidance system in reducing circling traffic?

Accepted Answer

Average search time for a parking space

Answer

Average search time (also called cruising time) directly measures how efficiently drivers find available spaces, which is the primary goal of parking guidance.

Question 5

A facility uses ultrasonic sensors in an open-air lot. Which environmental condition most significantly degrades their performance?

Accepted Answer

Heavy rain or snow accumulation

Answer

Precipitation—especially heavy rain and snow—creates false echoes and can cover sensor faces, causing ultrasonic sensors to misread occupancy status.
