Hourly changes in the number of people in KBR zones show where people travel at a given hour. These shifts are distributed over the roads, so every link gets its own daily rhythm. You can see which directions grow in the morning and which in the afternoon. Line width is traffic volume and the moving dashes show the direction of travel.

We combine data on where people are with traffic measurements and a network model — for your area, period and questions.
