The invention relates to the field of intelligent traffic control, and discloses an intersection adaptive signal control method based on a CV condition, and the method comprises the steps: obtaining the vehicle position data, the vehicle speed data and the vehicle head distance data of each lane of an intersection based on the CV condition; judging whether the entrance lane disturbs the upstream traffic flow or not according to the obtained data; if the entrance lane disturbs the upstream traffic flow, constructing a traffic flow conflict matrix, and determining a new phase scheme based on the traffic flow conflict matrix; determining the upstream average arrival rate of each entrance lane, the upstream traffic flow density of the entrance lane, the queuing traffic flow density and the saturation flow rate; and based on the upstream average arrival rate of the entrance lane, the upstream traffic flow density, the queuing traffic flow density and the saturation flow rate, calculating the green light duration required for clearing traffic interference of each lane in the new phase scheme, and obtaining the green light timing total period duration. Adaptive signal control is carried out according to different traffic states of the intersection, and the purposes of reducing intersection congestion and improving vehicle passing efficiency are achieved.
本发明涉及智能交通控制领域,公开了一种基于CV条件下的交叉口自适应信号控制方法,基于CV条件获取交叉口各车道包括车辆位置数据、车辆速度数据及车头间距数据;根据获取数据判断进口道是否对上游交通流造成扰动;若进口道对上游交通流造成扰动,则构造车流冲突矩阵,并基于车流冲突矩阵确定新相位方案;确定各进口道上游平均到达率、进口道上游交通流密度、排队交通流密度以及饱和流率;基于进口道上游平均到达率、上游交通流密度、排队交通流密度、饱和流率计算新相位方案中各车道清空交通干扰所需绿灯时长,得到绿灯配时总周期时长。以针对交叉口不同交通状态进行自适应信号控制,实现降低交叉口拥堵、提高车辆通行效率的目的。
