I'm having interest in Foundation and transportation arena.But I'm really confused that the branches having enoughscope ?

There are very less institutes which provide transportation engineering but it has vast scope as this is the growing branch of civil engineering as transportation is a booming field where the opportunities are endless. You can either concentrate on traffic engineering or go for the pavement design management.. Also, once you are done with M.tech in this branch you can go for Ph.D or you can start working in consulting firm or in R&D organisation. Apart from this, again I am saying better to follow what your heart says.
