The invention provides a changeable information identification device and method and a changeable information identification pushing method. The changeable information identification device comprises an arrangement position selecting module, a road network modeling module, a road network road condition associating module, a road condition marking module and a database establishing module, wherein the arrangement position selecting module is used for selecting the arrangement position of changeable information identification and determining information related to the arrangement position, the information related to the arrangement position includes road sections contained in the changeable information identification, the road network modeling module is used for establishing a road network map corresponding to each piece of changeable information identification according to the road sections contained in the changeable information identification after the arrangement position of the changeable information identification is determined, the road network road condition associating module is used for determining the road conditions of all the road sections in the road network map according to the data and road conditions fed back by a probe vehicle, the road condition marking module is used for marking the road conditions of all the road sections in the road network map corresponding to the changeable information identification with colors, and the database establishing module is used for recording the road network map of the changeable information identification and other related parameters and storing the recorded result in a database.
Description
technical field [0001] The invention relates to the technical field of traffic guidance, in particular to a variable information identification device, method and variable information identification push method. Background technique [0002] Traffic guidance is a comprehensive consideration of people, vehicles and roads, and improves the road traffic system by inducing the travel behavior of road users, preventing traffic jams, reducing the time vehicles stay on the road, and finally realizing traffic flow in the road network. Reasonable distribution on each road segment. [0003] Variable Message Signs (Variable Message Signs, VMS) is the most typical traffic guidance system. By providing the driver with real-time road condition information ahead, it can induce the driver to choose a reasonable route, avoid congestion or accident road sections, and improve road utilization efficiency. Domestic and foreign research tends to show that VMS-induced information can prevent cong...
