Camera images are updated every 10 seconds.

The congestion map is updated automatically every minute, 24 hours per day, 7 days per week.
Travel time routes
Travel times are only listed for routes in which congestion levels normally have an impact on the estimated travel times. This generally would include routes heading into the city in the morning and out to the suburbs in the evening. Additionally, the travel times shown on the web site reflect the messages displayed on the overhead message signs. If the travel time message isn't displayed on the sign, it won't be displayed on the web site.
For information on connecting to and using the traveler information data, see the developers page.
