## Measurement of Transport Supply and Demand for Passengers and Freight
Transport Supply
- Capacity: Number of vehicles, seats, or cargo space available for transportation
- Vehicle-kilometers: Total distance traveled by all transportation vehicles
- Frequency of service: Number of departures or arrivals per day or hour
- Speed of service: Average speed of vehicles on the network
- Reliability of service: Consistency of schedule and punctuality
- Infrastructure quality: Condition of roads, rails, ports, and terminals
Transport Demand
Passengers:
- Passenger-kilometers: Total distance traveled by passengers
- Passenger volume: Number of passengers transported over a specific period
- Origin-destination (OD) flows: Number of passengers traveling between specific points
- Trip purpose: Business, leisure, commuting, etc.
- Socioeconomic characteristics: Age, income, education, etc.
Freight:
- Ton-kilometers: Total weight of freight transported over a specific distance
- Freight volume: Total weight of freight transported over a specific period
- Commodity type: Type of goods being transported (e.g., raw materials, manufactured goods)
- Shipment size: Weight or volume of individual freight shipments
- Shipping frequency: Number of shipments per day or week
- Origin-destination (OD) flows: Number of shipments traveling between specific points
Additional Variables for Both Passengers and Freight:
- Fare or rate: Cost of transportation
- Travel time: Total time spent traveling
- Accessibility: Ease of reaching transportation services
- Reliability: Consistency of scheduled departures and arrivals
- Availability: Frequency and duration of service
- Modal choice: Decision to use a particular mode of transport (e.g., road, rail, air, water)
Measurement Methods:
- Surveys: Passenger and freight surveys to collect data on origin-destination, trip purposes, etc.
- Traffic counts: Manual or automated counts of vehicles and passengers at specific locations
- Load factor: Utilization of vehicle or network capacity
- GPS data: Tracking of vehicle movements and passenger flows
- Freight data: Collection of information from carriers, shippers, and ports
- Simulation models: Mathematical models to estimate supply and demand based on input assumptions
