Do tabled intersections actually slow traffic ? We are considering them on a mixed use street that is getting some street improvements over the next few years. Thoughts ?

I can't quote any studies, but in my opinion, vertical traffic calming really isn't that effective. It may slow traffic for a little bit, but drivers will speed up after to make up for lost time. I do know that cyclists hate vertical calming, and it . I think smaller curb radii, bumpouts, textured pavement, or a mini-roundabout would be just as effective. Psychological traffic calming (on-street parking, street trees, etc.) also works.

That being said, the municipality where I work, and the core city in the region, are both true believers in vertical traffic calming. Speed tables are very popular where I live. I was "persuaded" to add them into a FBC I'm writing, where earlier drafts prohibited all vertical calming. There's a lot of traffic congestion, bike traffic, and very rough pavement, though, so I don't think tables do much more to slow down traffic.

I agree with @Dan - narrowing streets, separating out lanes for bicycles, boulevard-like layouts, street trees, and mini round-abouts all are much more effective than any kind of speed bump or tabling -

I wouldn't underestimate the amount of noise speed tables generate, either. The "thump - thump" of mounting, demounting, and the sound of acceleration as drivers pull away (usually trying to make up for lost time). In a residential area, that noise may well be a deal-breaker. Put me down with Dan's suggestions.
