hello....myself Niraj .I want to get details about how to implement traffic alert system using sensors.If there is traffic congestion , then a message should be sent to the drivers coming from the same route from a distance.Plzz provide me details and code if u have.

The increase in the number of vehicles has led to traffic congestion. To overcome these problems, a system has to be designed which can alert for congestion. “Automatic Traffic congestion detection and alert system” does the needful and thus helps in reducing the traffic congestion. The suggested system detects the congestion levels in road traffic by processing camera image which are placed on roads to monitor the traffic condition. A LCD screen is placed at neighboring junctions for displaying message. When congestion is reported a LANE BUSY message is displayed on LCD along with an alert message is received on the mobile phone of control room including the location of traffic jam. Thus the rider has alerted for the congestion condition beforehand. This facilitates the rider in taking an alternate congestion free route, avoiding being stuck in the traffic jam. After the particular lane clears, the LANE CLEAR message is displayed on LCD. This helps in diverting the traffic and hence reducing congestion.
