EXPLORE AT YOUR OWN PACE

A city, from any angle.

Use your location, search a town, or enter coordinates. A bounded area of real buildings and roads loads around that point.

Take flight

WASD move · Mouse look · Q / E descend / ascend · Shift boost · F capture mouse · Esc release. You can also drag the view and use the scroll wheel, or use the touch controls. On mobile, slide the left thumbstick to move, drag the world with your other thumb to look, and hold the right-side arrows to change height. Pinch the view to move closer or farther. Tap the top bar for location, time and statistics, then Done to return to flying.

Change the hour

Move the timeline to explore today at any local time. Live time returns to the actual clock. Sunrise and sunset use the date and coordinates, including polar day and night.

About this little world

This is an illustrative simulation, not live congestion or a navigation tool. Vehicles follow connected roads, one-way directions, speed limits and a simple following-distance model. Junction yields are approximated; turn restrictions and real signal schedules are not modelled. Motorways carry more traffic than local and rural roads, with weekday morning and evening peaks.

Buildings use mapped heights where available, or mapped floor counts at 3.3 metres per floor. When both are missing, buildings default to two floors (6.6 metres). Terrain is flat; bridges are raised and tunnels are omitted. Map coverage varies. Up to 1,600 vehicles are shown to keep the scene responsive.
