(Connected Vehicle)

How V-2-I affects data collection

 

Immediate Needs

  • VMT by vehicle type and roadway functional class methods
  • VMT with local roadways methods
  • Travel Times
  • Speed data

 

Speed Data Format

  • Flexible – allows 15 to 25 bins
  • Flexible – allows 5, 15 or 60 minute time intervals
  • 5 mph bin increments
  • Flexible 10 mph (bicycle) to 120 mph speeds (safety)

 

Per Vehicle Data Format

Flexibility and foundation for other data programs

  • Axle Weights (left and right)
  • Axle Spacing's
  • Vehicle Speed
  • Vehicle Length
  • Time to sub second interval
  • Pavement Temperature
  • Headway / Occupancy
  • Inductive Signatures or other entry
