One of the most significant causes of truck drivers not complying with hours-of-service (HOS) regulations (thus leading to trucker fatigue and accidents) is the lack of awareness of available truck parking. The Federal Motor Carrier Safety Administration (FMCSA) led an initiative to better inform truckers of available truck parking by piloting a truck parking information system and analyzing the efficacy of the system.

A public rest area near Athens, TN located at mile marker (MM) 45 on I-75 Northbound (N) was selecting for the testing. An additional site was added at a non-operational weigh station at MM23 on I-75 N, 22 miles from the first site.

The design of the system was comprised of several significant system components, described below:
  • Detectors: Side-mounted infrared laser scanners used to detect vehicles at ingress and egress.
  • Doppler radars: Used to provide velocity and length information of a vehicle relative to the laser scanner. Vehicle length was used to classify vehicles
  • On-site processor: Used to process the scanner and light curtain signals.
  • Off-site server: Used to download and store data in a database.
  • Closed-circuit television (CCTV) cameras: Used for validating site space availability (ground truth).
  • Web site and data archive: Used to monitor the CCTV cameras and make corrections to the site as needed.
  • Dynamic message signs (DMSs): Utilized to disseminate parking availability information to users on the roadway.
  • Interactive voice response (IVR) system: Truck drivers were able to call 1-844-SMART-PK to check parking availability at the site and reserve a parking space.
  • Mobile application: Truck drivers were able to use the application on a smartphone to check parking availability at the site and reserve a parking space.
