The data traffic over a dedicated short‐range communications (DSRC) channel at each location grows with the number of communicating vehicles. This chapter illustrates the DSRC scalability problem and the need for effective and fair solutions. It discusses desired properties of DSRC congestion control solutions and describes at a high level several promising approaches. The chapter also discusses safety messages expected to be broadcast over a DSRC channel and how individual vehicles can estimate current channel load conditions. It considers only vehicle‐to‐vehicle (V2V) communications. The congestion control algorithms typically focus on the dynamic adjustment of message rate, transmission power, or both. For vehicle safety communications, the main goal of congestion control is to keep the overall channel load below a certain threshold. Proactive algorithms aim at preventing channel congestions in the first place. Reactive algorithms assume vehicles have the means to assess current channel load.
