The slides for this presentation can be found here.

Note: In the video, there is a reference made to electricity and water, but this is NOT applicable to CityLoops.
And here is an explanation on the National Statistics of Transport (NST).

Outline of the video

• Key part in our work
• Relates to all materials and products that are brought from outside of the city to the city.
• Fundamental work, because a vast amount of materials are imported and exported
• What are they, where do they come from, how do they move
• How does it happen: something crosses the city boundaries. We can consider how it crosses that. For example, by land with trucks or rail, by water with ships, by air with planes.
• Freight by train is more likely to be bulk materials (grain, coal).
• More hidden: transport by pipeline. (Water, gas)
• M5:33 overview
  • Highly relevant to all flows
  • Urban boundaries highly porous --> difficult to get numbers
  • Freight statistics are key
  • Transport-mode (TM) based vs. commodity-based (CB) approach
    • TM: quantify everything that goes by rail or by pipeline; tracks it by activity
    • CB: track all petroleum and look at various modes.
    • Practical to take one approach and then add things up.
    • Choice of approach is dependent on the data that is out there.
    
    
  • There is also imports and exports of energy
  
  
• M9:37, examples
  • South African ports
  
  
• M11:17, sources
  • Statistical agencies
  • Freight data agencies
  • Studies
  • Relevant governing bodies
  • Keywords: freight statistics, imports and exports + city name
