The Motorcycle Crash Map Viewer provides a simple means to explore motorcycle crashes in California. Users can view motorcycle crashes for a city or unincorporated county area and toggle by crash severity or alcohol involvement. The results are summarized in the map and in a list of crashes. The individual crash locations can be seen in a Google Street View profile page or downloaded into a spreadsheet.
To use this tool, click on Motorcycle Map Viewer from the Tools dropdown menu.
1. Select Location
First, select a County/City:
2. Select Factors
Next, the page will open up and the selected location will be loaded onto the map. Users can select:
- Severity levels (Fatal, Severe Injury, Other Visible Injury or Complaint of Pain)
- Alcohol Involvement
The selected options will automatically update on the map.
The crashes are represented by color-coded symbols. Colors match the severity level and the symbol represents whether or not alcohol was involved.
|Crash Severity||Alcohol Involvement|
|Injury (Other Visible)|
|Injury (Complaint of Pain)|
By clicking on an individual icon on the map, a summary of the crash details will appear, with a link to the interactive Google Street View profile page.
3. Other Features
The total count of crashes by severity and type are shown in the table. The list automatically updates depending on the selected options.
A list of crashes that are shown in the map are displayed with several basic fields regarding the location. The distance and direction refer to the offset distance from the secondary road along the primary road. Clicking the CASEID field zooms to the crash on the map.
