Every day, a vast number of drivers are suffering from traffic jams around the world. The intelligent transport system can be used to reduce traffic jams. In this paper, we proposed a traffic jam early alert protocol (TEAP) which could propagate the alert information of traffic jam to drivers through the VANET as soon as possible. The early alert information could help the drivers avoid the jammed area. With the TEAP, the alert information including the position of the event would be transmitted immediately along the roads by unicast once a traffic jam happened while broadcast would be used when the message travelled by the crosses of roads so that all the vehicles possible drive into the spot of the accidents would get the information early. Besides, the oncoming vehicles would help disseminating the information. The simulations showed TEAP improved the packets successful delivery apart from rapid disseminating information.
