GB and freight
Not yet documented
This case study appears in the agreed handbook structure but has no content in the source document. No definition, scope, hazard, tools, inputs or outputs have been supplied.
The page exists so its URL and sidebar position are fixed now rather than after publication.
What is known
Nothing beyond the name, which indicates a case study at Great Britain scale addressing freight.
Both aspects would be new. The three documented case studies are regional rather than national, and all three concern passenger transport rather than goods movement.
The freight modelling already exists
Unlike the Dover to Folkestone line, the components for this case study are documented in the handbook already.
| Component | Chapter |
|---|---|
| Freight demand estimation, shipments and vehicle tours | Freight demand |
| MILES, the logistics modelling package | Freight demand |
| MATRA, the road-freight electrification model | MATRA |
| Freight as MATSim activity plans | Freight demand |
What is missing is the case study applying them.
Points to resolve
Two things documented elsewhere in the handbook would need addressing for a national freight study:
MATRA's stated limitations. It is explicitly not a network traffic-assignment model: travel time is derived from an assumed average freight-vehicle speed rather than simulated congestion, and other modes are not represented. A study assessing climate disruption to freight would need to address how that interacts with flooded or degraded links.
MILES has no documented inputs or outputs. Both headings are present but empty in the source.
What would need supplying
| Item | As provided for |
|---|---|
| Scope and spatial extent | All three documented studies |
| Hazard and scenarios | North East England |
| Workflow diagram with inputs and outputs | North East England |
| Tools, and inputs and outputs per module | Requested but unfilled in the source for all studies |
