Attributing events to multiple routes?

Jol1234 — Mon, 19 Dec 2022 13:20:20 GMT

Hello,

Is it possible to attribute a single point event to multiple routes? For example if I want to attribute a traffic signal control box to two roads which are separate events how would I go about doing this?

Thank you

@Jol1234 Depending on the situation, there are multiple ways to handle this situation. Suggest reviewing the following resources, test the option that best applies to your use case.

Routes are concurrent, the dominant route is defined
- Route dominance
- Configure Route Dominance Rules
Extend the Event Attributes
- Events are tied to a single route, using business logic to define the primary association
- Event attributes can be extended to capture secondary route and measure
- Use GP tools like Update Measures From LRS or Locate Features Along Routes to update the secondary route and measure attributes

Thank you @AyanPalit,

I was hoping you could elaborate on if route dominance could apply to point events as well as linear ones? Also your bullet point about "Event attributes can be extended to capture secondary route and measure"

Would that just involve having an extra column in the event table for "secondary route"?

Thank you

Route Dominance rules are configured at the Network Route level and applies to both point and linear events.
Second option, is at the Network Event level. Extending the Event Attributes may look like:

Primary Route	Primary Measure	Secondary Route	Secondary Measure
R1	100	S1	50
R2	200	S2	150

Use GP tools like Update Measures From LRS or Locate Features Along Routes to update the secondary route and measure attributes
You may come up with your own/custom method to update the secondary route attributes.
