London Bus Stop Distance Analysis

Needs a discussion of the methodology of calculation.<p>The distances I&#x27;m getting from the downloaded &quot;bus-sequences.csv&quot; (from TfL&#x27;s API site) differ substantially; e.g my 53 has averages of 317m and 357m vs his 201m and 219m.<p>Additionally, my numbers match up with those of &#x27;superqwert from <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=20029476" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=20029476</a> for the 389 and 631 routes.<p>(I measured a bunch of stops of the 78 route with GPS earlier this week. My calculations correlated closely with the real* distances when the looseness of GPS from downstairs on a bus is taken into account.)

TFL uses so called PTALs to put a number on public transport accessibility.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Public_Transport_Accessibility_Level" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Public_Transport_Accessibility...</a><p>On a map - <a href="https:&#x2F;&#x2F;tfl.gov.uk&#x2F;info-for&#x2F;urban-planning-and-construction&#x2F;planning-with-webcat&#x2F;webcat?intcmp=25932" rel="nofollow">https:&#x2F;&#x2F;tfl.gov.uk&#x2F;info-for&#x2F;urban-planning-and-construction&#x2F;...</a>

I wish we had more &quot;long distance&quot; buses in London.<p>It takes forever to get anywhere on a bus because it stops so frequently. I&#x27;d be really keen to get buses that dont stop until they get to major places.<p>E.g. you could have bus routes that only go between stations on different routes. Take Camden Town to Finsbury Park as an example - no direct rail route between them, about 2.5 miles apart by road. The 253 stops <i>sixteen</i> times (according to Google Maps) when going between those stations.

For the TfL API, have a look at <a href="https:&#x2F;&#x2F;api.tfl.gov.uk&#x2F;" rel="nofollow">https:&#x2F;&#x2F;api.tfl.gov.uk&#x2F;</a>. You can also get GeoJSON line strings of the bus stops (or other modes of transport!) if you’re interested.

Some people who you might not normally expect to, do concern themselves about bus routes.<p><a href="https:&#x2F;&#x2F;www.sidis.net&#x2F;TransfersContents.htm" rel="nofollow">https:&#x2F;&#x2F;www.sidis.net&#x2F;TransfersContents.htm</a>

Thanks all for the help - some of you noticed the data was erroneous. It is all fixed now
