During this workshop, the Graffolution partners will present the most important results from the project. In addition the participants will be able to test the Graffolution platform which delivers an extensive set of “Collaborative Tools and Resources” to empower transport operators and other stakeholders such as city administrations and law enforcement agencies to share knowledge and to create own intervention strategies. Furthermore, Graffolution provides an interactive “Open Information Hub” addressing local communities, citizens and graffiti writers to strengthen public awareness and enforce the prevention of illegal spraying activities. The Graffolution consortium members will also use this opportunity to collect feedback and inputs from the workshop participants.
