Patent number: 10937312Abstract: 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.
