Frequently Asked Questions

Cameras

How often do the cameras update?
Most of the cameras update every 5 minutes. Rural camera may take a little longer depending on their network connection. At a minimum, all cameras update several times an hour.
I would like to see more cameras in a particular area.
Our network of cameras continues to expand. The TripCheck team continues to work with ODOT staff in various parts of the state to judge priorities for new camera installations. The ability to access phone and power sources, among other constraints, can limit our options for new camera sites. There are also costs for maintenance and operations that are considered. Currently, there are over 300 cameras on TripCheck. Citizens are welcome to send in their camera suggestions to the TripCheck Support mailbox.
Why don’t you have directional indicators on all cameras?
The cameras outside the metro areas have a direction indicator located in the right hand corner above the camera image. These cameras are always looking in the same direction. But most cameras in the Metro areas are Pan, Tilt, Zoom and can rotate at a moment's notice. Since they change direction, we can't place the direction above the image as we can with the permanently mounted cameras. Some of the new metro area cameras do have an electronic direction indicator on the screen but most do not.  To find the direction indication on Portland cameras that don't, click on the live streaming link below the camera image, there you will see a message stating that "traffic closest to camera is traveling east" (for example). 
Streaming Image
So, "live streaming" is now available on TripCheck?
Live streaming is available but limited to selected cameras in the Portland Metro area. To view this popular feature click on the Live Streaming link below the camera and the streaming image will appear. The streaming is limited to 60 second sessions. You must click on a link below the camera image to restart the streaming for another 60 seconds.
Why is the live streaming limited to just the Portland Metro area?
Live streaming is made possible through an agreement with trafficland.com. At this time the infrastructure required to support live streaming is only available in Portland. In the future it's possible that other areas of the state will be considered.
How does the live streaming work?
A new camera image is displayed every two seconds which gives an animated effect of live streaming. Other DOT's around the country use the same method when streaming camera images.
Does ODOT archive camera images?
ODOT does not save camera images. After an image is shown for its set duration it is then written over by the next camera image. Images are not archived due to the amount of resources it would take to save the thousands of images accumulated daily and to respect privacy concerns.
Why do only some of the cameras show the current temperature and wind speeds?
Cameras that display the current temperature and wind speed have a weather station close by to collect and feed the data. Because of the cost of these weather stations, ODOT can't justify placing a weather station at every location. Instead, we opt to spread the coverage out geographically.
Are TripCheck camera images and current road condition data available for private use?
The Oregon Department of Transportation allows businesses, private citizens and organizations to use data and images found on TripCheck. To begin collecting real time data users can sign up for a  TripCheck Travel Information Portal (TTIP) account. This information is formatted in Extensible Markup Language (XML) and it's suggested that users know XML as a pre-resiquite before signing up for a TTIP account. Go to this URL to sign up: http://www.tripcheck.com/TTIPv2
Is there an easy way to get a camera's URL?
To get the address of any camera right click on the camera image. A menu will appear, scroll down and click on "Properties". The address or URL can be found and copied under "Properties". ODOT should be credited for use of the camera. Language such as "Camera courtesy of ODOT" is acceptable.

Road Conditions

How is the winter road condition information obtained and how often is it updated?
During winter months, ODOT maintenance crews provide Road/Weather reports for our mandatory road reporting stations. These stations are located in areas that typically get the worst weather. The reports are displayed on TripCheck road conditions maps as Severe Weather Hazards (full blue circles) or Weather Warnings (half blue circles).
Crews provide these reports five times per day and at other times when conditions change significantly. The daily reporting times are approximately 4:00 AM, 7:00 AM, 10:00 AM, 3:30 PM, and 8:30 PM. Actual reporting times can vary depending on crew availability.
During major winter storms, personnel can be busy responding to incidents or clearing snow on certain highway segments which can cause delays in our reporting of conditions. Reporting may not occur during periods of good weather when crews are not on duty during some shifts. Road condition reports for non-mandatory reporting stations are reported only when conditions warrant.

What are snow zones?
 Designated by a white circle with a blue outline, snow zones represent a stretch of highway where you must carry tire chains or traction devices regardless of the road conditions. The snow zones are in effect during the winter driving season which begins in November or sooner if there is an early snow. The snow zones end in May but in some areas may continue into June if there is a late winter driving season. The snow zones will be taken off the TripCheck map when they are canceled for the season.
Do you report on the light green roads found on the TripCheck map?
The light green roads on TripCheck are displayed for reference only. ODOT does not report conditions for these roads. In most cases, these light green roads are National Park roads, Scenic Byway roads, USDA Forest Service roads and County roads. You should always make local inquiries for specific road and travel conditions, especially in remote areas. Some roads are impassable following severe weather conditions.
What is the "Alert" feature?
Travel and traffic conditions that have a major impact on motorists are displayed as "Alerts". Road Closures, delays over 2 hours, major NOAA (National Oceanic and Atmosphere Administration) alerts, and hazardous weather (both regional and statewide) are examples. You may also see Amber Alerts.
What are "Announcements"?
Announcements are related to TripCheck itself. If we add a new feature, have a service interruption, or make changes that impact users we will share that information as an Announcement.
Why do you have such broad categories for delay information such as "greater than 2 hours"?
It is very difficult to anticipate the precise time delay that any incident may cause considering the nature of the incident and potential injury to motorists. Serious incidents may require on scene investigations or the intervention of a HAZMAT unit which can extend the delay considerably.
We try to indicate a general factor for a delay that helps motorist make good decisions about taking an alternate route, delaying their travel, or taking another mode of travel. We make a very concerted effort to update our information as conditions change or we have better information to share.
I’ve seen temperature differences between the blue circle (or semi-circle) and the blue weather flags? 
The blue weather flags are automated weather stations that automatically take a weather reading every few minutes.
The blue circle or semi-circle are live reports from ODOT crew members who have relayed the current road and weather conditions. These road and weather reports cover a particular stretch of highway, rather than a single predesignated location. Crews provide reports (blue circles or semi-circles) five times per day and at other times when conditions change significantly.
Does ODOT have advice on what items should be carried in your car for winter or general travel?
ODOT has published a notice on general winter travelwith a number of helpful topics. Here is the URL: http://www.oregon.gov/ODOT/COMM/winterdriving.shtml

Local Traffic Information

Is there anywhere on TripCheck or TripCheck Mobile I can find local traffic?
Local municipalities have the capability to post local traffic information on TripCheck. If there is a local incident posted on TripCheck you will find it above the incident map in the region where it occured. On TripCheck Mobile you will find it under Incidents City/County. You will not see an incident listed for your town or county unless one occurs. Not all Oregon municipalities have committed to posting local information. This is a new service and some municipalities are just learning about it.

Archived Road Condition and Incident Data

How do I get an archived road condition or incident report?
Archived road condition reports for a particular State or US highway are available by request. These reports are available 24 hours after the date requested. In most cases, a simple road report can be turned around in one to two working days. To request an archived road report: TripCheck.Support@odot.state.or.us

Technical Issues

My browser is in Compatibility View, how do I turn it off?
In your browser click the Tools menu and find Compatibility View on the menu. Make sure it is unchecked. Additionally, you can click Compatibility View Settings and ensure TripCheck.com is not on your list of "Websites you've added to Compatibility View".
My browser is not showing me up-to-date images. What do I do?
What's probably happened is that your computer is showing old ‘cached’ images rather than the latest images from our cameras. We have seen a trend in people experiencing these browser related problems. Fortunately, there is an easy remedy to the problem. First, simply try refreshing your browser by pressing F5 on your keyboard or the refresh symbol on your browser. Your other option is to empty the cache. How you do that will depend on the browser you are using. If you continue to have problems, please email us at: ODOT TripCheck Support (TripCheck.Support@odot.state.or.us).
Is it possible to turn traffic reports on and off that I signed up for via your Twitter feeds?
Turning Twitter updates OFF and ON
  • ON: turns ALL your authorized Twitter updates and notifications on.

TripCheck Mobile and 511

Is TripCheck Mobile an "App" specifically designed for the IPhone?  
Screenshot of TripCheck mobile.
No. TripCheck Mobile was created long before the IPhone and it was design to work universally on all different types of handheld devices. Some private developers have created such "Apps" but they are not affiliated with TripCheck or the Oregon Department of Transportation.
Under Road Conditions and Incidents, the highway I want information about is not listed. 
TripCheck Mobile only lists highways when there are adverse conditions or an incident to report.  If there is no incident or adverse conditions reported on a particular highway, then you will not see a listing for that highway.
Why don't you include the TripCheck maps and weather forecasts on TripCheck Mobile? 
When TripCheck Mobile was first designed it was built for small hand held devices with limited capabilities and small screens which would make it difficult to view the maps. Also, the Mobile site was organized to give users a quick snap shot of the current conditions and incidents so some of the features such as the detailed NOAA weather forecasts were not included on the mobile site.
Do 511 get the same road conditions and incident information as TripCheck? 
Yes. As soon as an incident is reported to our dispatching center, the incident is entered into a data base and the information is distributed to TripCheck, TripCheck Mobile and 511 at the same time.
What do I do if there is loud background noise that interferes with my commands?
Because 511 listens for your voice command, background noise can interrupt voice commands. After the third interruption, the user is automatically switched to the key pad only function.
Are 511 initially limited to just Voice Commands? 
You can use your key pad at anytime to execute commands.
