Disclosed aspects relate to transportation vehicle traffic management. A traffic controller detects a first traffic state parameter value for a first lane. In response to detecting the first traffic state parameter value, the traffic controller establishes a first broadcast of a first movement value (e.g., speed, acceleration, direction). The first movement value may indicate a first movement pattern for a first set of vehicles in the first lane. In response to establishing the first broadcast of the first movement value, the traffic controller detects a second traffic state parameter value for the first lane. In response to detecting the second traffic state parameter value the traffic controller modifies the first broadcast of the first movement value. The modified first movement value may indicate a second movement pattern for the first set of vehicles in the first lane.
