  • 1. Under the esteemed guidance of Mr.G.CHAKRAPANI M.Tech Assistant Professor Department of E.C.E Presented By CH.RAMADEVI P.KONDALA RAO SK.MADAR SAHEB CH.HARIKA B.SRINIVASA RAO 09X91A0473 09X91A04A9 09X91A04B3 09X91A0475 09X91A0468
  • 2.       Abstract Introduction Technology Used Project information Software used Conclusion
  • 3.  The main goal of engineering is the planning and management of traffic systems.  One aspect of the project aims at developing a traffic control algorithm for future technology.  We then deal with all four routes  i.e. East, West, North and South
  • 4.    A newly emerged area is demand estimation through microscopic traffic modeling. According to development of our project it is a step by step analysis of traffic system. Emergency sensor is built upon, to continuously check the emergency situations like ambulance, police and fire-bridge etc.

  • 18.  Traffic is the most essential part of modern world as “Time is money”.  The Quality Assurance Professional can be a part of each of these review process.  It is basically based on four way traffic  But with slight modifications it can be made for any way systems effectively as it is based on Boolean algebra
