PoloSolo has defined the framework but is withholding city totals until comparable accommodation, cost and support evidence has been independently reviewed. SoloScore is not a crime index, official advisory or guarantee.
The 100-point structure
Official advisories, scenario-specific risks and women’s solo-travel context.
Airport arrival, night transport, public transport and walkability friction.
Solo-friendly stay supply, staffed reception and access to support.
How predictable and transparent common solo-trip costs are.
Small groups, communal stays and solo dining without forced socializing.
Connectivity, payments, navigation and language friction.
A worked comparison, without a fake score
Suppose two stays have the same final price. Stay A has written late-check-in instructions, a staffed desk and a simple airport connection; Stay B has an uncertain key handoff and a difficult final walk. The framework would favour Stay A on arrival and support evidence. It would not claim that the surrounding area is safer, and it would not award invented points before the evidence set is complete.
Confidence and publication gates
Future results will show High, Medium or Limited confidence. High means current official and operator sources cover the core dimensions and important claims have been corroborated. Medium means the central decision fields are covered but lower-impact details remain limited. Limited means important evidence is incomplete, older or too narrow for a confident conclusion.
Source order
- Local governments, airports, transport operators, police and emergency services.
- Official travel advisories, with the issuing nationality or audience visible.
- Established research used only at the geographic level it supports.
- Merchant inventory as a price or availability input, never an independent endorsement.
- Consented traveller experience, labelled as experience rather than fact.
Update rules
Source-access dates remain visible. Volatile emergency, transport, price and advisory details are rechecked before travel and after a material source change. A city safety conclusion cannot be inferred from a route recommendation or one government advisory.
