Embodiments of the disclosure provide a method for adjusting a backoff mechanism and a vehicle communication system. The method includes the following. Vehicle information of each vehicle in multiple road segments is obtained. Current traffic flow information of each of the road segments is determined based on the vehicle information of each of the vehicles. Multiple probabilities corresponding to each of the road segments are determined at least according to the current traffic flow information of each of the road segments, in which the multiple probabilities corresponding to each of the road segments correspond to multiple candidate contention window sizes respectively. A contention window size corresponding to each of the road segments is determined based on the multiple probabilities corresponding to each of the road segments. A message retransmission mechanism of multiple first vehicles is controlled according to the contention window size corresponding to a first road segment.
