Describe Event Behavior Rules

NEGraf — Tue, 31 Mar 2026 20:42:10 GMT

I am using the arcpy describe option to view events and their rules, following this example:

https://pro.arcgis.com/en/pro-app/latest/arcpy/functions/locationreferencingdataset-properties.htm

What is returned is a JSON format with "ActivityType" and "BehaviorType" as codes. Does anyone know where to find the what the codes mean? Here is an example of the output:
[
{
"LrsId": "{BC081F2A-6B2F-4A9E-9BA1-1569499FBFB9}",
"NetworkId": 1,
"EventTableId": "{575E204F-8875-401C-8280-F16950E00A07}",
"EventBehaviors": [
{
"ActivityType": 1,
"BehaviorType": 1
},
{
"ActivityType": 2,
"BehaviorType": 1
},
{
"ActivityType": 3,
"BehaviorType": 1
},
{
"ActivityType": 4,
"BehaviorType": 4
},
{
"ActivityType": 5,
"BehaviorType": 1
},
{
"ActivityType": 6,
"BehaviorType": 4
},
{
"ActivityType": 7,
"BehaviorType": 4
},
{
"ActivityType": 12,
"BehaviorType": 6
},
{
"ActivityType": 13,
"BehaviorType": 1
}
]
}
]

There is a domain in the Roads and Highways database that seems to correspond to ActivityTypes 1-7, but not 12 and 13. I have not found anything for BehaviorType.

Regards,

Nick

Hello Nick,

Apart from ActivityTypes 1 through 7, they are not documented. When you create an ALRS, check out the dActivityType domain for descriptions of codes 1 to 7. To supplement that, code 12 is for Cartographic Realignment and code 13 is for Load Route.

For the Behavior type codes, they aren't documented either since they are typically only exposed through the ArcGIS Pro Location Referencing user interfaces. You can figure them out through some trial and error if you are inclined (i.e. 1 = Stay Put).

Also related, the Relocate Events REST API (Relocate Event | ArcGIS REST APIs | Esri Developer) uses named constants instead of integer values when reading event behavior types (see the eventBehaviors parameter)

@NEGraf Recommend using Generate Schema Report tool (ArcGIS Pro 3.2+) to get the report that includes LRS configuration details in a readable format as in example below:

Hey Nick. Following up on the information in Clive and Ayan's posts, see below for coded value Activity Type and Event Behavior tables.

Note: This is not authoritative. The information in MnDOT's lrsMetadata eventBehaviorRules seems to contain event tables and values no longer in use. I'm assuming those are related to ArcMap R&H.

I used these references to compile the tables (thanks to Clive, Ayan, and RHUG group for the info):

- The "LR" worksheet has a lookup table that helps to join EventTableId/Event ID to get Event Names)
