- use center of each direction's stops to check if it might be a match for N/S or E/W - check that (?)70% of stops for each direction confirm the split - replace or append/prepend N/S E/W to existing trip head-sign (if route long name == trip head-signs ??) - (?) better than using the last stop name as direction head-sign? - agency setting for overriding/trying fist E/W N/S for direction head-signs? ---------- - test with Calgary Transit route 86 (same head-sign, same last stop, 2 loops starting/ending from terminal)
