Traffic Map

The interactive Traffic Map (add link) shows up-to-the-minute information about traffic on major roadways in Southern California. The map is updated every minute and displays the county you choose at the top of the page. To show the entire Southern California region, select “All Counties.”

The traffic map page provides graphical and text information about travel times, road conditions, incidents/Sigalerts, highway camera images, message sign content and traffic speeds. It also gives you access to information about roadside assistance, Park&Ride lots, carpool lanes and toll roads.

You can easily navigate around the traffic map using the pan and zoom functions on the upper left side of the map. Use the “+” to zoom in and the “-“ to zoom out, or slide the cursor between the “+” and “-“ to zoom in and out. You can also move around the map using the arrow keys or by putting your cursor on the map and using the grab function to move around the map.

The inset map on the lower right side of the main map shows your map view in relation to the larger available area. You can use the inset map to change the location of the main map by selecting one of the counties.

Map Content

The map is interactive: you can show just the layers that you want to see by checking the boxes in the Map Legend beside the information you want displayed on the map.

Hovering over an icon on the map will give you a small window that displays details about that icon. The window disappears when you move the mouse away from the icon. To keep the window open, click the icon instead of hovering over it. Close the window by clicking on the "X" in the top right hand corner of the box.

Traffic Speeds/Travel Times - the color of the line on the roadway when the Traffic Speeds box is selected indicates the current average speed on the road segment, according to the colors shown in the legend.

By hovering your mouse over the road segment, a hover box will appear that provides information about the current average speed on that segment and the travel time between the interchanges where the segment begins and ends.

There are Color Options available if you need to change the traffic speed road colors. Click on Color Options to display other options. Select a speed link color combination by clicking on the radio button beside the set of colors you prefer. Then close the option box by pressing the "Hide Color Options" link.
