Safe-D: Safety through Disruption

Connected Vehicle Information for Improving Safety Related to Unknown or Inadequate Truck Parking



Safety issues that stem from commercial truck parking shortages are a national concern. National hours-of-service (HOS) regulations limit drivers’ time on the road, in an attempt to increase safety by limiting fatigue; thereby, creating a need for drivers to locate safe, secure, and legal parking wherever they are when or before they hit their limits. In addition, the recent rule mandating the use of electronic logging devices (ELD) to electronically record a driver’s Record of Duty Status (RODS), replacing the HOS paper logbooks, further exacerbates drivers’ needs to find adequate parking. If drive time is exhausted where there is no nearby truck parking, drivers may park in unsafe or unauthorized locations to meet HOS requirements or they may continue to drive while fatigued. As a result, there are intrinsic safety impacts to all highway users due to large trucks parking in unsafe locations or truck drivers driving past their allotted hours. And, with the projected growth of truck traffic, the demand for adequate truck parking will continue to outpace the supply of public and private parking facilities. The current study will help transportation agencies in developing solutions to the parking availability problem by identifying effective methods for using data to estimate truck parking demand and areas of parking opportunity, assessing available data sources for estimating truck parking demand and supply, and determining the safest connected vehicle (CV) solutions for distributing information on parking availability directly to drivers.

Project Highlights

  • The research team successfully developed the Truck Parking Demand and Supply Analysis ArcGIS Map for Howard County, Maryland, which can be accessed at
  • The Guidebook to Evaluate Inadequate Truck Parking and the Summary of Findings PowerPoint provides a high-level overview of how State DOT planners and data analysts can estimate truck parking demand and identify truck parking supply in their respective regions.
  • The research team submitted a paper summarizing the project findings and results to TRB and the paper was selected for presentation at the 2023 TRB Annual Meeting: Gick, B. N., Parab, S., Katsikides, N., Hwang, W., Lee, D., Rivera Montes de Oca, J., Farzaneh, R., Kong, X., Srisan, T., Bell, S., Alden, A., Warner, J., Romano, H., Schrank, D. (2022). Connected Vehicle Information for Improving Safety Related to Unknown or Inadequate Truck Parking (No. TRBAM-23- 00724).
  • The project provided funding to four Ph.D. students from Texas A&M and the students were able to learn valuable skills and knowledge that can be used to further their education and careers.
