Clusters of Connected Roads (IMAGE)
Caption
Clusters of connected roads. Same color denotes roads that are part of the same cluster, i.e., all connected. When there are no hacked vehicles, all roads are connected (yellow). But as there are more hacked vehicles, more colors show up, and each cluster is inaccessible from the other. When somewhere between 10-20% of vehicles at rush hour hacked, the size of the largest cluster dramatically reduces. We call this threshold (~10-15 hacked vehicles/km/lane) the point of city fragmentation. Essentially half the city is inaccessible from the rest above this threshold.
