FAQs

What types of incidents you have?

There are two types of incidents: curated incidents (Accidents, construction, events) and calculated incidents (flow/congestion incidents). Curated incidents are from sources such as DOTs, twitter feeds, police scanners and other sources and are managed by the INRIX incident group. Calculated incidents (i.e. our flow incidents) are a type of incident that is calculated at INRIX and compares real-time speeds with free flow speeds in order to allow for an understanding of abnormal conditions. Here is a case study of how PennDOT is utilizing these flow incidents: https://inrix.com/blog/2019/11/pennsylvania-dot-study-highlights-how-crowdsourced-data-can-be-a-game-changer/

Do you have historical incidents available?

Yes - we have a historical incident product line that is provided through http://analytics.inrix.com. This includes Construction/Accident incidents back to August 2016. Our Flow incidents are additionally provided through the historical bottleneck tool also located at http://analytics.inrix.com. If you would like trial access to roadway analytics, please sign up here: http://www2.inrix.com/trial-roadway-analytics

What is the latency for getting a road closure or other map incidents in the Inrix system?

We can typically get a road closure or other map incident in the INRIX system within 2-3 minutes of a closure althought there are cases where it can take longer.

What does Inactive incident status mean?

An inactive incident is an incident that is not currently happening, but is expected to be at some point. For example, construction which happens overnight, every night, long-term construction lifted for the holidays, etc.

What are congestion incidents?

Congestion Incidents (also called flow incidents or XDFI) are representations of abnormally queuing traffic (that is, worse than NAS) which are concatenated into incident objects - each congestion incident representing one queue, to the extent that that is ontologically possible. Congestion incidents will always be of “Type=3” in the XD Incidents API output. They contain only queue-based information (length, speed, tendency, delay). A congestion incident will never contain cause or effect information such as “accident”, “lane closed” etc.

Is there a way to show Congestion incidents that are not repeating?

We provide flow data with indicators of ‘fromTypicalFlowMinutes’ as well as ‘fromFreeFlowMinutes’. Both of these are indicators of how severe the congestion incident is. You can additionally utilize filters like ‘minFromTypicalFlowMinutes’ which allows you to only see congestion incidents of a certain severity.

For example, if you are seeing repeated congestion that you would expect everyday, then applying a ‘minFromTypicalFlowMinutes’ filter should only return flow incidents that are atypical.

How are severity levels for flow incidents set?

With a two-factor algorithm which takes the delay in minutes over NAS and the road class into account. See chart below where for example a delay of between 500 and 900 seconds on a FRC 1 road is a severity 2:

Delay (Seconds) FRC 1 FRC 2 FRC 3 FRC 4 FRC 5
< 180 - - - - -
180 + 1 1 0 0 0
300 + 2 1 0 0 0
600 + 2 2 1 1 0
900 + 3 2 2 1 1
When is status considered “active” versus “cleared” for congestion? It seems like incidents within the same version are considered active, cleared, and inactive. When do these get triggered as active or inactive?

There will be times when a congestion incident can go from active to cleared and then back to active. If there is an incident that meets our criteria for being cleared, but then another congestion incident shows up that is similar enough to the previous flocongestionw incident, we will give it the same ID and mark it as active.

Will a congestion incident ever be considered “inactive”?

There are no cases of congestion incidents being output in Inactive. Congestion incidents are output as “cleared” for 30 minutes after they have ended (ie, when traffic has returned to normal), as is the case with other incidents.

How do I identify the amount of time of each incident version was valid?

The length of time that each version of a congestion incident by using the LastUpdated field. So the lifespan of version n is: LastUpdated of version n+1 minus LastUpdated of version n. So for example, incident 113374983 : Version 1, LastUpdated 2019-07-31T13:22:34.256365Z Version 2, LastUpdated 2019-07-31T13:27:42.0822358Z Version 3, LastUpdated 2019-07-31T13:36:34.5505373Z Version 4, LastUpdated 2019-07-31T13:37:43.781517Z Version 5, LastUpdated 2019-07-31T13:41:37.9177832Z Version 6 (CLEARED), LastUpdated 2019-07-31T13:46:28.2832673Z o the lifespan of version 1 was 5 minutes and 8 seconds, and that of version 2 was 8 minutes and 52 seconds,etc. Version 6 doesn’t have a meaningful lifespan as it is a cleared incident.

TMCs The list of TMC segments affected by this incident.
ParameterizedDescription The description separated into parameters.
RDS The Radio Data System data. See the RDS element for more information.
ShortDescription Short textual description of the incident including language code.
FullDescription Longer textual description of the incident including language code.
TTSDescription The incident is described as if a human were reading the incident.
HeadTail The location of the start and end of the incident.
incidenttype Query String The types of incidents to output. Multiple incident types can be specified in a comma-delimited list. The default is “Incidents,Construction,Events,Flow.”. Note, the first letter of each option can also be used. For example “I,C,E,R” also will work.
Value Description
Incidents This option returns all unusual incidents that may slow down traffic such as a car accident.
Construction This option returns only construction incidents.
Events This option returns unusual events slated for the area such as a major sporting event.
Flow This option returns reports about the slowing down of traffic on your route.
RoadWeather GetXDIncident calls only. This option returns Road Weather incidents.
incidentsource Query String A value of “INRIXonly” specifies that incidents are compiled from non-commercial sources, such as flow incidents that are generated programmatically from Inrix traffic information or planned construction incidents. A value of “Community” specifies that incidents come from community sources, such as incidents submitted through mobile devices. The default is INRIXonly.
Value Description
INRIXonly Return incidents from non-commercial sources.
Community Return incidents from community sources.
severity Query String Filters incident reports based on severity level. This value can be in the range of 0-4, with 4 indicating the highest severity. Multiple severity values can be specified in a comma-delimited list. You can specify all severity values by not including this parameter or by using an empty value.
units Query Integer Use 0 for English units, 1 for metric. Default is 0.
status Query String The status of the incident. Possible values are Active, Cleared, Inactive or All. Default is All.
advancewarning Query Boolean If the incidents returned should be limited to only ones which require advanced warning. Default is true.
Format Query String The format of the response in either XML or JSON. Default is XML.
starttime Query Datetime The incidents for this future time. The default is the current time. All times should be in UTC or have the timezone offset as specified in DateTime Values and be specified using the ISO 8601 format.
minDelayFreeFlowMinutes Query Integer Filters out incidents with a FreeFlowMinutes delay less than the value set.
minFromTypicalFlowMinutes Query Integer Filters out incidents with a FreeFlowMinutes delay less than the value set.
minDelayDistance Query Integer Filters out incidents with a delayDistance value less than the value set.
locRefMethod Query String The location reference method returned for the incidents. Supported values are TMC (default), TMC11 or XD. Multiple values can be submitted separated by commas. Specifying TMC11 will return the normal 9 character TMCs with a 2 letter ISO country code which is needed because in some cases, the 9 digit TMCs are duplicated between countries. Using the TMC11 clarifies this duplication.
locale Query String The language for description text. US English is the default locale. Specifying locale=local will return the default language for this region. For further information, see Incident Locales.

severity Query String Filters incident reports based on severity level. This value can be in the range of 0-4, with 4 indicating the highest severity. Multiple severity values can be specified in a comma-delimited list. You can specify all severity values by not including this parameter or by using an empty value.
units Query Integer Use 0 for English units, 1 for metric. Default is 0.
status Query String The status of the incident. Possible values are Active, Cleared, Inactive or All. Default is All.
advancewarning Query Boolean If the incidents returned should be limited to only ones which require advanced warning. Default is true.
Format Query String The format of the response in either XML or JSON. Default is XML.
starttime Query Datetime The incidents for this future time. The default is the current time. All times should be in UTC or have the timezone offset as specified in DateTime Values and be specified using the ISO 8601 format.
minDelayFreeFlowMinutes Query Integer Filters out incidents with a FreeFlowMinutes delay less than the value set.
minFromTypicalFlowMinutes Query Integer Filters out incidents with a FreeFlowMinutes delay less than the value set.
minDelayDistance Query Integer Filters out incidents with a delayDistance value less than the value set.
locRefMethod Query String The location reference method returned for the incidents. Supported values are TMC (default), TMC11 or XD. Multiple values can be submitted separated by commas. Specifying TMC11 will return the normal 9 character TMCs with a 2 letter ISO country code which is needed because in some cases, the 9 digit TMCs are duplicated between countries. Using the TMC11 clarifies this duplication.
locale Query String The language for description text. US English is the default locale. Specifying locale=local will return the default language for this region. For further information, see Incident Locales.

action Query String Use getXDIncidentsinSegments
token Query String A valid authorization token returned in response to a GetSecurityToken request.
segments Path String The predefined comma-delimited list of segments for which to get data. Any duplicate segments are ignored. Note an alternate method of sending the segment list is to include in the POST body as a key-value pair which allows for a longer list of segments to be specified. When doing this, use the header "Content-Type application/x-www-form-urlencoded".
incidentoutputfields Query String The incident fields to output. Multiple fields can be specified in a comma-delimited list. The default is the primary incident element attributes, short and long description, TMCs and Parameterized description.

ID The unique identifier of an incident.
Version The version number of the incident report, incremented each time an incident report is updated.
Type The type of the incident (Incidents, Construction, Events, Flow, Area, or Weather). Incidents can be determined from the Alert-C event code, Construction indicates the presence of road construction, Events can be weather-related or a scheduled sporting/public event, and Flow indicates a blocking incident.
Severity The severity of the incident. This value can be in the range of 0-4, with 4 indicating the highest severity.
EventCode The event code of the incident. These are standard Alert-C event codes.
LatLong The latitude and longitude of the incident.
Impacting Whether the incident impacts traffic flow. This field is set to “yes” if the appearance of the incident changes the traffic flow below a certain percentage from that which is normally expected for the given segment of road at that time, given the current conditions.
StartTime The starting time of the incident.
EndTime The ending time of the incident.
DelayImpact Provide the delay in minutes versus typical conditions and versus free flow conditions.

ParameterizedDescription The description separated into parameters.
RDS The Radio Data System data. See the RDS element for more information.
ShortDescription Short textual description of the incident including language code.
FullDescription Longer textual description of the incident including language code.
TTSDescription The incident is described as if a human were reading the incident.
HeadTail The location of the start and end of the incident.
incidenttype Query String The types of incidents to output. Multiple incident types can be specified in a comma-delimited list. The default is “Incidents,Construction,Events,Flow.”. Note, the first letter of each option can also be used. For example “I,C,E,R” also will work.
Value Description
Incidents This option returns all unusual incidents that may slow down traffic such as a car accident.
Construction This option returns only construction incidents.
Events This option returns unusual events slated for the area such as a major sporting event.
Flow This option returns reports about the slowing down of traffic on your route.
RoadWeather GetXDIncident calls only. This option returns Road Weather incidents.
incidentsource Query String A value of “INRIXonly” specifies that incidents are compiled from non-commercial sources, such as flow incidents that are generated programmatically from Inrix traffic information or planned construction incidents. A value of “Community” specifies that incidents come from community sources, such as incidents submitted through mobile devices. The default is INRIXonly.
Value Description
INRIXonly Return incidents from non-commercial sources.
Community Return incidents from community sources.
severity Query String Filters incident reports based on severity level. This value can be in the range of 0-4, with 4 indicating the highest severity. Multiple severity values can be specified in a comma-delimited list. You can specify all severity values by not including this parameter or by using an empty value.
units Query Integer Use 0 for English units, 1 for metric. Default is 0.
status Query String The status of the incident. Possible values are Active, Cleared, Inactive or All. Default is All.
advancewarning Query Boolean If the incidents returned should be limited to only ones which require advanced warning. Default is true.
Format Query String The format of the response in either XML or JSON. Default is XML.
starttime Query Datetime The incidents for this future time. The default is the current time. All times should be in UTC or have the timezone offset as specified in DateTime Values and be specified using the ISO 8601 format.
minDelayFreeFlowMinutes Query Integer Filters out incidents with a FreeFlowMinutes delay less than the value set.
minFromTypicalFlowMinutes Query Integer Filters out incidents with a FreeFlowMinutes delay less than the value set.
minDelayDistance Query Integer Filters out incidents with a delayDistance value less than the value set.
locRefMethod Query String The location reference method returned for the incidents. Supported values are TMC (default), TMC11 or XD. Multiple values can be submitted separated by commas. Specifying TMC11 will return the normal 9 character TMCs with a 2 letter ISO country code which is needed because in some cases, the 9 digit TMCs are duplicated between countries. Using the TMC11 clarifies this duplication.
locale Query String The language for description text. US English is the default locale. Specifying locale=local will return the default language for this region. For further information, see Incident Locales.
