Probability-density risk-maps for tourism during emergencies

• Emergencies negatively affect tourism as people are afraid for their safety. • We develop a dynamic probability-density risk model to map an area's actual risk. • Exploiting public data, an example on London, shows these maps' dynamic risk-representation. • We show that these maps help tourism during emergencies yet preserve people's safety. • These maps constitute a predictive model to formulate tourism scenarios and guide...
