The invention discloses an expressway traffic jam guidance information issuing method and system, belongs to the technical field of traffic guidance, and solves the problems that an existing expressway traffic jam detection mode has space limitation, cannot perform comprehensive space-time perception on a traffic jam event, and is poor in traffic jam detection effect. The technical problem of quickly and effectively inducing and evacuating the vehicles in the direct influence and indirect influence range of the congestion event is solved. Comprising the following steps: if a traffic flow operation state is congestion, determining a direct influence range, an indirect influence range and an event response level of a current congestion event through air patrol equipment; dividing the indirect influence range into a plurality of speed limit intervals, and determining a vehicle speed limit value and interval length of each speed limit interval; generating traffic guidance information corresponding to each speed limit interval according to the event response level, the ramp distribution condition and the vehicle speed limit value; and issuing corresponding traffic guidance information through the VMS guidance equipment arranged in each speed limit interval and the hovering air broadcast equipment.

    本发明公开了一种高速公路交通拥堵诱导信息发布方法及系统,属于交通诱导技术领域,解决现有的高速交通拥堵检测方式具有空间局限性,无法对交通拥堵事件进行全面的时空感知,实现对拥堵事件直接影响和间接影响范围内的车辆进行快速有效的诱导疏散的技术问题。包括:若交通流运行状态为拥堵,则通过空中巡查设备确定当前拥堵事件的直接影响范围、间接影响范围以及事件响应等级;将间接影响范围划分为若干个限速区间,并确定每个限速区间的车辆限速值以及区间长度;根据事件响应等级、匝道分布情况以及车辆限速值,生成各个限速区间对应的交通诱导信息;通过各个限速区间中布设的VMS诱导设备以及悬停的空中播报设备,发布对应的交通诱导信息。
