transportohemi

Transportohemi is a theoretical construct in transport studies that models flows of goods, people, and information across hemispheric-scale networks. It treats the globe as two interlinked hemi-systems and seeks to quantify cross-hemispheric interactions while incorporating local and regional dynamics. The framework aims to separate hemispheric-level constraints—such as seasonal demand, cross-ocean capacity, and macroeconomic conditions—from subhemispheric variations, enabling a modular analysis of transport performance.

The term blends transporto- (from transport) with hemi- (half) and was introduced in scholarly work in the early 2020s by researchers exploring simplified representations of global networks. It is intended as a modeling abstraction rather than a literal geographic partition, useful for high-level scenario analysis and comparative studies.

Key features of transportohemi include the decomposition of flows into hemispheric and subhemispheric components, a coupling term that represents inter-hemispheric interactions, and scalable parameterizations for demand, capacity, and cost. The approach supports scenario testing, such as shocks to cross-hemispheric routes, policy changes, or seasonal patterns, by adjusting a small set of governing parameters while preserving a consistent global framework.

Applications of transportohemi span supply chain design, port-network planning, and policy evaluation. In practice, analysts use it to explore how hemispheric differences in infrastructure, regulation, and economics influence overall network performance, or to compare alternative transportation regimes under distinct global conditions.

Limitations and reception are mixed. Critics note limited empirical validation and potential oversimplification of complex, multiregional dynamics, while proponents emphasize clarity and tractable comparison across large-scale scenarios. The concept remains a tentative tool within broader transportation and regional science research.
