Caltrans road restrictions include wind advisories, closed roads and winter chain control. CHP incident reports include accidents, road debris and road closures. The home page shows 3 tabs: Caltrans, CHP and Favorites. The screen shots below show examples of CalRoads. The Caltrans tab shows a list of all numbered roads. Each list item indicates the part of the state with road restrictions. If you click on a road or enter its number in the text field, CalRoads displays details about the road. The region names are color coded to indicate whether the road is closed (red), has warnings (yellow) or has no restrictions (green). When the "Show" button is depressed, CalRoads shows the details about the restrictions.
The CHP tab shows all CHP regional dispatch centers in blue, ordered in a geographical order. If you depress a blue row, it expands to show local CHP areas within the region, each in green. The number in each row shows the number of incidents. If you click on a green row, CalRoads shows partial details about each incident. If you depress, the "Show Details", CalRoads shows full details about the incident. CalRoads translates the cryptic CHP abbreviations into English. Sometimes, CalRoads keeps the original term and shows the translation within square brackets. A menu item lets you see the raw data if you wish.
The Favorites tab shows Caltrans roads and CHP areas that you have selected as your favorites.
