FAQPage Schema

How do I measure event impact on regional trajectory volume?▼

To measure event impact on regional trajectory volume, this skill applies a DID-style estimation across event windows, comparing treatment and control regions to evaluate changes in mobility activity levels.

What is DID estimation and how does it work for mobility analysis?▼

DID-style estimation for mobility analysis measures regional activity changes by splitting data into treatment and control groups, then calculating the difference in trajectory volumes before, during, and after specific events.

Can I use this to analyze spatiotemporal data for rainstorms or sports events?▼

Yes, you can analyze spatiotemporal data for rainstorms or sports events. The skill evaluates how these specific events alter regional trajectory volume by comparing pre-event, during-event, and post-event windows.

How do I set up treatment and control splits for trajectory analysis?▼

You set up treatment and control splits for trajectory analysis by providing an evidence file. The skill uses these regional splits to perform DID-style calculations and isolate the event's true impact on mobility.

What's the best way to evaluate policy interventions using event windows?▼

The best way to evaluate policy interventions using event windows is applying DID-style estimations to trajectory data, measuring the contrast between treatment and control regions before, during, and after the intervention.
