Southern California Traffic Phone HelpWhat does IE511 provide traffic information for?The IE511 service provides traffic information for all freeways in Southern California. This information is organized into segments from intersecting freeway to intersecting freeway. For example, traffic along the 60 freeway is provided in segments from the I-10 to the I-215, the I-215 to the 91, the 91 to the I-15, and so on. You will be asked to identify the freeway you are requesting information for, your direction of travel, and the segment from intersecting freeway to intersecting freeway. View the traffic map to see the freeways for which traffic information is available. The only areas that do not have traffic information are colored gray. These areas are not available because there is no detection equipment installed in the roadway that would allow congestion reporting. We still report incidents on those roadways. Why didn’t 511 tell me about the incident that slowed my trip?511 receives the majority of its incident information from the California Highway Patrol (CHP) and Caltrans. This information is reported as it is updated by both the CHP and Caltrans. Sometimes, you will experience an incident before it is reported on the system. Occasionally, there are more incidents on a single highway than we can report. 511 only plays the top five incidents in terms of severity. Sometimes there is just too much traffic. This is reported as congestion and travel times are given. |
