I got a copy of LWcfg and I assume I have a compiled program somewhere because I have traffic on my freeways but nothing on my new roads. I could find nothing about getting traffic onto my roads in the FSX Autogen SDK or anywhere else.Is there something published somewhere by MicroSoft?

You need to read the Shp2Vec section in the Terrain and Scenery HTML file under the Terrain SDK.

Hi John.Hiway traffic is a vector ( shp2vec ). It is the FWX type, and refered to as Freeway in the SDK.Search the "Terrain and Scenery.html" for the info. Notice it is a clip 15 instead of the normal clip 11. The vector examples have an example.Also, see this thread about "excluding" traffic:http://forums.avsim.net/dcboard.php?az=sho...6&mesg_id=33106Dick

Thanks to you both...it turns out that FSX_KML will do the job of adding traffic. I'm not crazy about the SDK as a tutorial for feebs at my level.
