dear student
M-tech in transportation has vast scope , especially in a developing country like India that too under Modis rule.
Any engineering study which deals with transportation facilities in context of designing, operation or planning comes under transportation engineering.
Designing of transportation facilities includes
Operational Analysis of transportation facilities includes
Planning Analysis of transportation facilities
Transportation engineering is really a very good specialisation to be taken in mtech.
From your question let me guess you are from a state engg college and if so then doing mtech in NIT will be a good choice both from placement (though a little chance) and teaching (maximum chances occur here) point of view.
hope this helps
All the best!!!
