Transport and Mobility

Transport and Mobility is a chapter of Critical Infrastructure: a specialist sub-community with its own group, editor and research agenda. Transport under the infrastructure profession.

01In brief

The short answer.

Transport and Mobility is a chapter of Critical Infrastructure: a specialist sub-community with its own group, editor and research agenda. Its work starts from the cornerstone topic, transport and mobility. Transport network resilience is the ability of roads, rail and public transport to keep moving people and goods through disruption and to recover quickly. A chapter becomes a platform of its own only by meeting the graduation rule.

From enquiry to contribution.

Canvas · from enquiry to contributionDesign, not a record
Transport and Mobility: a working group from charter to sunsetA charter sets the question and the code of conduct; members join with declared interests; a workplan produces deliverables that are reviewed and credited; the group reports and sunsets or renews. Design of the process, not a record of a run.

03Geography

Infrastructure exposure in Western Europe.

For transport and mobility, in GCRI's spatial-intelligence reading, the map opens on night lights, true-colour imagery and population density with night lights tonight from NASA GIBS, framed on Western Europe; 3 further NASA layers wait in the list.
