  Traffic Congestion is one of the severe problems in heavily populated
countries like Bangladesh where Automated Traffic Control System needs to be
implemented. An FPGA-based Semi-automated system is introduced in this paper
including a completely new feature "Safe State" to avoid sudden unwanted
collision. Here we used sequential encoding which has made the program much
simpler and so that easy to control and modify. The experimental result showed
the automated change in traffic lights according to the specified timing
sequences which would be able to conduct maximum possible transitions of
vehicles occur at different directions simultaneously without facing any
accident.
