While I was QCing this one I noticed 3 intersections were being tagged to the same intersection at Lawrence/Yonge.
Needed to change the abbreviations to get correct matches: Greenholm Crct, Scarborough Golf Club Rd, Fortune Gt.

The `intersection_name` is an internal name following the convention `[E / W street name] / [N / S street name]`.

3. **date installed**
`date_installed` is the *date of the first row of data from the location* (so if the first row has a `datetime_bin` of '2020-10-05 12:15', the `date_installed` is '2020-10-05'). `date_installed` can be found by querying:
to update `date_installed`, the following script can be run, where the temp table contains the first date of which a recording was made for a specific intersection_uid (previously defined). The output is then joined on the intersections table:

```sql
SELECT MIN(datetime_bin)::date FROM miovision_api.volumes WHERE intersection_uid = 122;
-- Drop temp table if it exists
DROP TABLE IF EXISTS temp_min_dates;

-- Recreate temp table with restriction to specific intersection_uids

Nice update on this sql. You don't need to add an index here because this is a very small table. Indexes work like textbook indexes, to help identify which chapter/page to look at, but in this example your textbook is one paragraph.

Once the above is finished, we have completed updating the table [`miovision_api.intersection_movements`](../readme.md#intersection_movements). **Though, the valid movements should be manually reviewed looking at the following criteria.**

- are there any major vehicle movements missing: through/left/right
- are there any ped movements missing: clockwise/ccw
- if any of these are missing, investigate and see if that movement is legitimately not allowed (usually through the leg restriction clause of the intersection - should be updated before)

Below is an example script + output you can use to aggregate movements into a more readable format for QC. In particular look for intersections with very short lists of valid movements, or no valid movements for certain classifications.
