Josh,

I got a report from a CT3 user that my program wasn't showing that
those buses stopped at either of these stops:

1010 Massachusetts Ave opp Magazine St (stop tag 128)
Massachusetts Ave @ Magazine St (stop tag 30009)

Looking at the xml file that NextBus gives for the CT3 path [1] you
can see the problem: those two stops are listed correctly in the
initial route definition section:

...
<stop tag="128" title="1010 Massachusetts Ave opp Magazine St"
lat="42.3279799" lon="-71.06774" stopId="00128"/>
...
<stop tag="30009" title="Massachusetts Ave @ Magazine St"
lat="42.32806" lon="-71.06805" stopId="30009"/>
...

But they are not listed as being on either the inbound or outbound routes:

<direction tag="708_7080014v0_1"
title="Andrew Station (Limited Stops)"
name="Inbound" useForUI="true">
<stop tag="11802"/>
<stop tag="11803"/>
<stop tag="1805"/>
<stop tag="1784"/>
<stop tag="17861"/>
<stop tag="17862"/>
<stop tag="77777"/>
<stop tag="15088"/>
<stop tag="5089"/>
<stop tag="855"/>
<stop tag="13_ar"/>
</direction>
<direction tag="708_7080017v0_0"
title="Beth Israel (Limited Stops)"
name="Outbound" useForUI="true">
<stop tag="13"/>
<stop tag="10014"/>
<stop tag="5090"/>
<stop tag="1790"/>
<stop tag="7"/>
<stop tag="17863"/>
<stop tag="1799"/>
<stop tag="11802_0"/>
<stop tag="11803_0"/>
<stop tag="1805_ar"/>
</direction>

I wrote a small validator to check if there are other places where a
stop is defined for a route and then never used, as these are likely
to be mostly errors, and I found 252 other cases. They are at the end
of this email [2]. There are probably other cases where a route should
contain a stop but doesn't, but these are ones that we may be able to
catch automatically.
