Question
Dear ZZ

Can there be design and construction challenges in installing traffic signals in tunnels?.

Thanks
Prashant

Answer
Certainly, design and installation can require much engineering efforts .

Those I have seen are layed out to keep traffic moving through with out back up congestion and traffic lights are away from entrance and exit of the tunnel.

I have not personally seen cases where traffic signals were inside the tunnel, however. Have you?
