I would like to test my hardware under vibration that can appear on a highway gantry. If someone has a model of such vibration. i.e period and amplitude.

In my lab I have a motor that can be regulated according to its RPM.

You could move your hardware (assuming it'll fit in a van) to somewhere near a highway. Too obvious? –  user346 Apr 5 '11 at 9:24
Do you have a set of accelerometers? You could go measure a highway gantry directly. –  Colin K Jun 2 '12 at 1:24

I'm not sure that this completely answers your question but LIGO must deal with ground vibration due to highway traffic (and other sources). They have a paper with measurements at https://dcc.ligo.org/LIGO-C950577-v2/public

A highway gantry will most likely receive most vibration from wind. It's not a building but the vibration patterns might be similar. Check out http://www.scirp.org/Journal/PaperInformation.aspx?paperID=3889

put it on a big board, supported at either end with brick say, and then get some people to stamp on the board in the middle while you test it. To make the vibration heavier, just add more people.

actually, this is quite funny. –  Dimensio1n0 Nov 2 '13 at 13:44
