SoloScore is not a crime index, an official advisory or a promise that a traveler will be safe. Official government advice is displayed separately and always names the audience it addresses.
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.
Confidence and publication gates
Every score must show High, Medium or Limited confidence. A numeric result is withheld while core evidence remains in research. PoloSolo’s four pilot cities currently demonstrate that withheld state rather than publishing plausible but unreviewed numbers.
- High: current official and operator sources cover the core dimensions, with additional corroboration where needed.
- Medium: the principal decision fields are reviewed but some lower-impact details remain limited.
- Limited: important evidence is incomplete, older or too narrow to support 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 and structured review signals, never merchant marketing alone.
- Editorially screened traveler experience, labeled as experience rather than fact.
Update rules
Official advice is checked most frequently; emergency information, transport and prices require at least a 90-day manual review cycle. A material source change or advisory escalation returns affected content to review. Dangerous-area claims, emergency numbers, last-service times and city safety conclusions cannot be auto-published.
