Issues with Arcade Attribute Rules for Road Data Checks

[Smileyk_mdt]

Hello,

I'm trying to create an attribute rule that checks to make sure a divided highway exists for each median. Not sure if the logic is incorrect or if I'm misunderstanding the spatial relationship. It is flagging some correctly and some not. If a median does not have a divided highway on it, it may be correctly flagged, but another one close by will not get flagged (even tho it should).  Here is the code and a picture. in the pic, the median running north south (greenish line) should also be red (error) as it doesn't have a divided highway underneath

This started with a clean dataset and deleted divided highways to test. In the clean data, each median will share the same route ID as a divided highway. I tried to flag errors based on attributes to keep it simple. I added in a spatial check but that still doesn't work.

// Check if the median is active (TO_DATE is NULL)
if (IsEmpty($feature.TO_DATE)) {

    //Get Divided Highways
    var highways = FeatureSetByName($datastore, "Divided_Highway_Export", ['ROUTE_ID'], false);
    var hwyRouteID = $feature.ROUTE_ID;

    // Filter highways by ROUTE_ID
    var matchingHighways = Filter(highways, "ROUTE_ID = @hwyRouteID");

    // Flag if NO matching highways were found
    if (Count(matchingHighways) == 0) {
        return true // flag median: no matching div hwy found
    }

    //Spatial check
    var intersectingHighways = Intersects($feature, First(matchingHighways))

    //Flag if no intersecting highway
    if (intersectingHighways) {
        return true //flag median
    }
    //If both conditions are true, pass validation
    return false
} else {
    return true; // Skip validation for retired medians
}

 thanks for any help
