Sometimes there is white between segments (there should just be continuous color).

Follow up to #9.

Looks like this is enabled, but can you add it to the repo description so there is an easy link?

Regarding:

- Do we want to interpolate the colors? or have hard breaks between them?
- Style the rest of the geometry (highways, primary roads, etc) that we
  don't have in our sample data

Let's mock up:

• fast above 100 km / hr
• medium: between 60 and 100 km / hr
• slow: between 30 and 60 km / hr
• stopped: less than 30 km / hr

no color interpolation (just sharp breaks)

Looks like animation is still running, even with the line is too thin to effectively see it. Removing the animation at low zooms should improve performance.

Many of the smaller roads in Manila (e.g. tertiary) just don't move as fast as motorway speeds, but our colors and the speed breaks are biased for the bigger express routes. This makes the neighborhood streets look "grid locked", but in fact traffic is probably moving like "normal" there with respect to city street speed regulations. On a highway it may be 100 km/hr, but on a surface road it may be 45 km/hr max regulation speed.

Maybe we can use the same "colors", but with different speed breaks per road class, in Tilezen kind syntax:

• highways: highway = motorway
• major road: highway = primary, secondary, tertiary
• minor road: highway = residential ... and most others

@patriciogonzalezvivo what do you think? 2 or 3 different shaders, or one shader with a property we can toggle per kind of road?

Shader changed, line widths need to change.

And morning, try 7am - 9 am range

On the road Maria Clara we have 2 features on top of each other – they should instead be pointing opposite directions and offset from each other. Notice how this works on Vicente Cruz "correctly", though maybe there is a difference of oneway=true versus oneway=false here.

Not sure if this is a Tangram problem or data problem on the server.

Right now it's a default time range, but in the future there will be a dynamic time range so this should accommodate static and dynamic labels.

Using PSD Geraldine provided

Use same technique as Bike Map.

At least in Manila! Here is traffic visualization on Refill, and compared to Walkabout which has the road direction arrows. Both for oneway roads and not oneway roads.

But the overlay does draw?! Chrome Version 56.0.2924.87 (64-bit).

Works fine in Safari version 10.0.3 (10602.4.8.0.1).

Related to #17.

Set this up in Dat interface

Seems like server is slow enough to need a loading indicator.

Not sure the server supports this now?

Should make use of Dat interface, see #9.
