RE: Traffic light signals
Dear Mr Hart,
We are currently undertaking a research project for TxDOT concerning the wind induced fatigue
of traffic signal structures at our Reese Research facility. We aim to test 3 traffic signal mast
and arms, 30, 48 and 60ft with associated traffic lights and ancillaries over the 3 year life of this
project. Basically we will measure the wind induced motion for these arms and working in
collaboration with UT Austin estimate the fatigue life of these structures. We had a 48ft arm for
an earlier project which recently failed and are seeking a replacement for it and perhaps a shorter
36ft arm as well. We have a 60ft arm on loan from TxDOT.
The reason I write is to ask whether it would be possible to borrow from Lubbock City Council
a 30 or 36ft mast and arm and a 48ft arm for this project. Apparently TxDOT in Lubbock does
not have any spare structures and they have suggested we approach you. Should you have any
queries on this matter please do not hesitate to call you. My student Hector Cruzado, has spoken
with David Elliot of your Department which is the reason for this approach
Thanking you for your consideration,
Yours faithfully,
Dr C.W. Letchford
