The invention discloses a bidirectional dynamic coordination control method for an oversaturated
trunk road. The bidirectional dynamic coordination control method comprises the steps of determining ideal
phase difference according to the running properties of queued vehicle
stream and arrived vehicle
stream, determining the
green time for meeting the traffic demands and avoiding the intersection congestion, determining queued vehicle weight
impact factors by different control strategies, and taking maximal release amount as a target for realizing coordination control of the
trunk road in a first direction; based on the coordination control in the single direction, calculating and coordinating the
phase difference, the
green time and the release amount at the intersection of the
trunk road in another direction for different status combinations in three statuses of green lamp loss, intersection congestion and new traffic
stream compensation at the intersection in the other direction of the
trunk road; and in combination with coordination control algorithms in two directions, realizing the bidirectional dynamic coordination control of the oversaturated
trunk road. The bidirectional dynamic coordination control method for the oversaturated
trunk road is suitable for traffic oversaturated trunk roads in big cities, and is capable of effectively reducing the queuing length and the
delay time at the intersection on the trunk road, improving the overall passing capability of the trunk road and avoiding the spread of
traffic congestion.
