I just upgraded to the latest version of WP Google Maps and now a traffic layer is on the map, and I can't find anywhere to disable it. Actually, I found Google traffic layer option, but it doesn't seem to have any effect. I tried both "enabled" and "disabled"
This is installed on a test site at http://enteloscms.amosagency.com/contact-us/ and I also have "WP Google Maps - Pro Add-on" installed, but the traffic layer was there before the addon.
WP Google Maps: Version 4.22
WP Google Maps - Pro Add-on: Version 3.10
