[OSM-talk] Wide roads and traffic signals

[Moshe Sayag]

Hi everyone,

I am trying to map my area (that is very sparsely mapped in OSM
currently), so I bought a GPS device and started cycling / driving
around and edit my tracks.
The results so far can be seen at

http://www.openstreetmap.org/?lat=32.1878&lon=34.8714&zoom=14&layers=B00FT
(Notice that the street names is not shown in Mapnik but only in Osmarender)

My questions:

1. How do I map a wide road with a separation (line of trees) between
the two directions?
Something like:

-->-->-->-->-->-->
-->-->-->-->-->-->
*  *  *  *  *  *  *  *
<--<--<--<--<--<--
<--<--<--<--<--<--

Do I set it as a one two-way road or two one-way roads?

2. If I set it as two separate ways, how do I mark traffic signals
(traffic lights) where two such roads cross each other?
