To explore the real-time
Congestion Map, click (and hold) your mouse over one of the navigational
arrow buttons (located outside each edge of the map), or the Zoom Controls,
located at the top right of the map.The roads will automatically change
color every minute to indicate the current traffic conditions. Each color
corresponds to a particular speed range, as indicated by the Map Legend.
Roll over a road segment to find out the current average speed across all
lanes.
On pop-up speed indicator bubbles, the speed is indicated by the number at
the top center of the bubble (X indicates no sensor data is available.)
Below the speed will be a directional indicator. N=North, S=South, E=East,
W=West, I=Inner Loop, O=Outer Loop.
Speed data provided by
Trichord Inc. and
VDOT. Please obey all posted speed-limits.
