Which wireless communication standard is most commonly used for vehicle-to-infrastructure (V2I) communication in smart parking systems?
Answer: DSRC (Dedicated Short-Range Communications)
DSRC operates in the 5.9 GHz band and is the primary standard adopted for V2I communication including parking guidance and payment systems.
A parking facility wants to implement dynamic pricing. Which data input is LEAST relevant to an automated dynamic pricing algorithm?
Answer: The age of the parking structure
Dynamic pricing algorithms rely on real-time occupancy, historical demand, and temporal factors—not the physical age of the structure.
In a smart parking system, what does 'ground truth validation' refer to?
Answer: Verifying sensor data accuracy against physical observation
Ground truth validation involves physically auditing the facility to compare actual occupancy against what sensors are reporting to ensure data accuracy.
Which metric best measures the effectiveness of a parking guidance system in reducing circling traffic?
Answer: Average search time for a parking space
Average search time (also called cruising time) directly measures how efficiently drivers find available spaces, which is the primary goal of parking guidance.
A facility uses ultrasonic sensors in an open-air lot. Which environmental condition most significantly degrades their performance?
Answer: Heavy rain or snow accumulation
Precipitation—especially heavy rain and snow—creates false echoes and can cover sensor faces, causing ultrasonic sensors to misread occupancy status.
What is the primary advantage of a 'pay-by-plate' system over traditional pay-and-display in smart parking?
Answer: It allows enforcement to be automated using LPR without requiring a physical receipt
Pay-by-plate links payment to the license plate number, enabling LPR-based automated enforcement without drivers needing to display a paper receipt.
In the context of smart parking data analytics, what is 'churn rate'?
Answer: The frequency at which parking spaces turn over (new vehicle occupies vacated space)
Churn rate (or turnover rate) measures how frequently parking spaces cycle between occupied and vacant, indicating space utilization efficiency.
