APPENDIX F. TRUCK PARKING METRICS

Table 10. Tier I truck parking metrics.

Category	Metric	Data Resources	Readiness	Scale
Demand	Truck Travel on NHS	HPMS, FAF	Current	Corridor
Supply	Number of Spaces, Public and Private	State inventories of public spaces and use of private truck stop resource for private data	Current; requires State data input and purchase of private data	Corridor and Facility
	Number of Spaces in Relation to NHS Mileage	HPMS mileage for the NHS	Current	Corridor
	Number of Spaces in Relation to VMT	HPMS VMT	Current	Corridor
	Number of Spaces in Relation to GDP by State	Bureau of Economic Analysis GDP Data	Current	Corridor

FAF = Freight Analysis Framework • GDP = Gross Domestic Product • HPMS = Highway Performance Monitoring System • NHS = National Highway System • VMT = vehicle miles traveled

Table 11. Tier II truck parking metrics.

Category	Metric	Data Resources	Readiness	Scale
Demand, Driver Demographics and Needs	Utilization for Public and Private Facilities (hourly, weekly and monthly)	State DOT inventories and surveys; truck stop owner and operators	Data Collection Required	Facility
	Parking Needs by Driver Type	Driver Surveys	Anecdotal	Facility
	Parking Needs by Industry Represented	Driver Surveys	Anecdotal	Facility
Demand, Economic	Origin and Destination Information	FAF/CFS/Use of Vehicle Probe Data	Current for FAF and CFS, use of FPM requires additional analysis	Corridor and Facility
Demand, Safety	Inventory of Problem Locations	Interviews with State motor carrier safety staff	Current	Corridor and Facility
Economic Valuation, Demand, Supply, Development	Proximity to Industry and Highway Facilities	GIS shape files for parking locations; industrial locations; travel time data	Current and Data Collection Required	Corridor and Facility
Safety	Hours of Service Violations	State DOT and Police Records	Current	Corridor and Facility
	Fatigue-Related Crashes	State DOT and Police Records	Current	Corridor
Supply	Amenities at Parking Facilities	State DOT and Truck Stop Owners and Operators Survey Data	Current and Data Collection Required	Facility
	Inventory of Driver Perceived Shortages, Parking Challenges	Driver Surveys	Anecdotal	Corridor and Facility

CFS = Commodity Flow Survey • DOT = Department of Transportation • FAF = Freight Analysis Framework • FPM = Freight Performance Measures • GIS = Geographic Information System
