One thing the DoT could do to assuage our negative feelings is put the methodology out in the public after it's implemented.
It likely is public - there may be an environmental assessment (EA), Environmental Impact Statement (EIS) or Environmental Impact Report (EIR) that will have an appendix containing the detailed traffic engineering study behind the metering. It's probably based on MUTCD guidelines [0].
Assuming you are referring to I-5 through CA, a Google search for "california ramp metering study" brings up a lot of studies and documentations sponsored by Caltrans.

- remarkEon 11y agoI'm actually referring to I-5 up here south of Seattle...right outside JBLM where I work. I have looked and unfortunately I haven't found anything. I did find a bunch of stuff that talks about ramp metering at large, but nothing specifically about the on-ramps here that just got metered. Anecdotally, traffic inside JBLM has been significantly negatively effected because of this. I read in another comment that ramp metering speeds up traffic on the freeway...I really hope that's the case. Because it's really annoying to sit in my car while trying to leave and I hope I get to make that up on the aggregate. And to my earlier point...it isn't immediately clear that I will...because the methodology isn't open.
