Updating to the newest version of Google Maps SDK allows the traffic layer to auto-update but also introduces a new traffic incident symbol that looks similar to the WSDOT traffic alert icons.
Google Maps SDK v3.10.0 is the last known version that will auto-update the traffic map layer and does not include new iconography (released August 10, 2020).
Updating to v6.0.1 caused an issue with the Google Maps traffic layer auto-update feature so we reverted the commit back to v3.7.0 https://github.com/englehorn/wsdot-ios-app/commit/c5f9fd8720dc54ff7141072bb4178e6189232fcd
