Description

## Environment

- Android OS version: All
- Devices affected: All
- Maps SDK Version: All

## Observed behavior and steps to reproduce

Traffic layer draws some strange and odd lines where there are no roads.

## Expected behavior

Traffic layer is only on roads

## Notes / preliminary analysis

We have custom implementation of traffic layer with the standard styles, but also using Style.TRAFFiC_DAY also draws these strange lines all over the place which dont follow roads. So there appears to be something off with the traffic source data set

Research direction

Start by reproducing the issue on Android with the standard traffic layer and Style.TRAFFIC_DAY, then compare the rendered lines with the underlying traffic source data. Done means traffic lines appear only along roads; the issue provides no files or tests to guide a code change.
