  • The USA doesn’t often build automated light metros, so it’s necessary to take stock of what works (platform-screen doors, construction planning, off-street viaducts that dodge traffic outright) and what doesn’t (cost of construction in VHCOL area).

    No doubt, there are probably many other things that have gone wrong in the project, but unless the USA starts building more, it’ll never learn from those mistakes.

    Case in point: the original US Interstate freeway standards used to specify that median barriers were optional if the median was wider than 30 ft (~9 meters). But later research showed than even 45 ft of median could still allow a vehicle to cross-over into oncoming traffic. The standard is now 60 ft, with old freeways were retrofitted with cable barriers to gently slow a wayward vehicle.


  • Likely, yes. But also, starting construction from the west meant fewer delays from right-of-way acquisition, since much of the elevated track was built through areas that haven’t been fully built out yet. This also allowed fine-tuning the building method, since essentially the entire line is on elevated viaducts. What they learned from the first segment becomes improvements when building in the denser areas eastward.

    The phased approach also recognizes that existing bus service was not as robust as in the tourist-heavy, built-up, denser east harbor area. So starting the rail service in the west means existing buses can be transformed into feeders to the rail line, which can carry people eastward faster than the congested highways.




  • Methodology:

    To determine the bath, shower and bidet hotspots around the world, we calculated the percentage of hotel bookings in each country, state and city that have showers, baths or bidets.

    We used Booking.com to determine the total number of accommodations (hotels, apartments, holiday rentals, etc.) in each geography and then found the number of accommodations in each geography that have either baths, showers or bidets using Booking.com filters.

    I was unable to find an option for “baths, showers, or bidet” in the booking.com filters, let alone options for each of those individually. So I’m not sure about the exact data used for this infographic.




  • Sources: Aviation Stack Exchange

    If a citation is going to point to any of the Stack Exchange Q&A pages, it is extremely important to specifically cite the exact post or answer, since – not dissimilar to Wikipedia – the quality, consistency, and biases of Stack Exchange answers is paramount for evaluating the information presented, especially factual data to be fed into an infographic.

    I personally am intrigued at these $800 economy, ten-hour flights, as well as a total omission of freight cargo in the underbelly. As presented, this flight has 180 passengers and runs for ten hours. This would suggest it’s not a common narrow-body, either the Boeing 737 or an Airbus A320, as even their largest available configurations can’t fit 180 people in a 2 class setup, let alone a 3 class setup. It could possibly be the Airbus A321, though.

    My point is that if it’s a widebody aircraft or the A321, not hauling cargo would be some staggering malfeasance for a commercial revenue airliner. But I can’t follow-up on any of these queries, since the sources aren’t properly cited.
