Automated Traffic Control System

  1. 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. 2.       Abstract Introduction Technology Used Project information Software used Conclusion
  3. 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. 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. 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
