Quick thoughts that can help
ride regularly around traffic to develop your awareness /reaction time/common sense approach to various traffic situations. I commute regularly in a city and it certainly helps with keeping these skills up (touch wood)
For the specific sections that you mention, and others, it can sometimes help to not be travelling at rush hour work starting finishing times, especially if there's a lumber mill or cement factory or whatever, to hopefully have less trucks returning for end of day etc. Not easy to plan for, but can help, even with regular cars with people rushing home for dinner sort of thing.
other than that, it's really about observing and reacting accordingly to stuff.
