Introduction

  • Trucking contributes to 71% of the freight tonnage transported in the United States
  • “Freight Transportation Forecast” reveals a 36% growth in freight volume by 2031
  • Link-leveltraveltimesaddressvariationsandreliability
  • Average travel time (ATT), buffer time index (BTI), planning time index (PTI), and travel time index (TTI) are suitable performance measures
  • Geospatial mapping helps to visualize and understand the region-wide truck travel patterns and identify chokepoints
