## What is California Traffic?

Disclaimer: This unofficial app does not represent any government agency and is not affiliated with California Highway Patrol (CHP). The source of the data is publicly available CHP data feeds at https://cad.chp.ca.gov/Traffic.aspx

A map, push notifications, and a data feed of incidents reported by California Highway Patrol (CHP). 

Categorized into a past 1-hour incident map, past 3-hour incident map, and past 3-hour data feed. The Google Map zooms to your last slewed location automatically upon launch.

Setup up to four custom locations for push notifications. For each location, choose a radius of 5, 10, 15, or 20 miles. If a new incident is reported within a circular region centered at your specified location with radius of your choosing as well, you will get a background push notification. If you are active in the app, you will NOT get a notification. You will NOT get push notifications for incident updates, only for the initial incident report. Some incidents are reported initially with no coordinates, and may or may not be notified. Please remember to Refresh the app frequently. Pull down or press down on any push notification to get a map preview within the notification. Tap a notification to launch the app centered to where the location was reported (NOTE: If you tap a notification after three hours of when it came in, the incident details will no longer be available).

Use simple search phrases like "fire" and "sig alert" to filter the incidents on the map or data feed. Also, search by incident type, city, county, or any other incident-related text you see on the map or data feed.

The map includes Apple Weather. The user can locate the Apple WeatherKit features in the app by first panning, zooming, swiping, or rotating the map's center to the location where a current weather measurement and/or hour-by-hour forecast is desired. The map's center is represented as the blue pin. Tap the blue button at the bottom of the map titled "Weather at Blue Pin" to view the location's current weather conditions in an alert view pop-over. The hour-by-hour forecast is accesible from this pop-over. NOTE: If the user taps a red incident pin, it will centered, and the blue pin will go over-top the red incident pin. The pin will show a rectangular callout. That callout can be tapped to see further incident details. However, if the weather is desired, tap the blue button at the bottom of the map titled "Weather at Blue Pin". The weather can also be accessed from the incident details page from the blue button in upper-right corner titled "Weather".

In this app, weather conditions relevant to travel are shown as current conditions and as an hour-by-hour forecast, using the Imperial system. The forecast begins 2-3 hours ahead of the user's current time. The current conditions shown are temperature, "feels-like" temperature, wind, wind direction, wind gust, visibility, cloud cover, and UV index.  The forecasts show hour-by-hour predictions for temperature, wind, wind direction, wind gust, % chance of precipitation, amount of precipitation in inches, snowfall amount in inches, cloud cover percentage, visibility, and UV index. NOTE: Only iOS 18+ users can see snowfall amounts forecasted.

All incidents now show city and county.

Tracks data updates to the incident input by CHP (i.e. adds more information to the incident listing as it comes in).

Incident details include latitude & longitude, and a zoomed map.

Does not report on criminal incidents.

Some of the types of incidents reported on are:

### 2/5 — Obnoxious weather pin

*2025-04-30*

This new weather function is beyond pointless. More of a hinder. No easy way to close out of an option tab. Simple is always better.

### 1/5 — Confusing and Clumsy

*2017-10-07*

I’ve used several apps covering the same information. This is the worst so far. Deleted after a few minutes of use.

**Developer response:** Many updates have been issued since your review.
