Rhodes City in Greece has issues with traffic congestion and lack of parking due to its small size and concentration of visitors. The document proposes three measures to address this: A) Create a pedestrian zone in the city center covering 600 by 300 meters and ban cars. Construct parking at the edges and use small electric buses to circulate the pedestrian area. B) Build two underground parking lots and extend the pier at Mandraki harbor to create a large submerged parking area, generating a new seafront plaza. C) Change the uses of administrative buildings to reduce visitors and cars, converting them to cultural/entertainment spaces to enhance the city and tourism.
