Traffic in California can get real hectic, especially when you have to hit the highway during rush hour. This great little widget will show you the flow of traffic in nine different areas in Southern and Northern California and around Phoenix. The information is well detailed and panning over any area of the map will show you the speed of traffic at different areas near there. The widget provides a legend for the different speed and accident levels, which show up as little dots on the map.
Although the pan view provides lots of useful information it can get on your nerves, since it pops up as soon as you drag your arrow on the map. The over profusion of the speed dots on the small map can also quickly clutter up the screen.
On the whole though, SigAlert Traffic Maps is extremely handy, as it refreshes every 3 minutes and provides detailed traffic information in almost all of California.
