Due to increasing traffic density, driving takes longer time within cities than in highways. The situation is worse in peak hours, when people travel from home to offices and vice versa. Emergency services, like ambulance services, fire brigade, police service etc., are directly affected due to increased traffic density. The existing traffic monitoring techniques will fail to provide real time traffic information to the user. India is known for billion populations and like in majority of developing countries like Indian roads are non-lane based and it has chaotic traffic. The existing traffic monitoring techniques are mainly infrastructure based system. Which is expensive and it requires constant maintenance. This paper focuses on fetching real time traffic information which is infrastructure less based system which is inexpensive in nature and it is also reachable to a normal person, like fetching real time traffic information from user who carry smart phones which play a role of sensor during their travel. This leads to building of wireless sensor network of mobiles.
