Embodiment 1
[0046] Such as figure 1 As shown, it is a flow chart of a specific embodiment of a point-of-interest-oriented wayfinding sign layout method according to the present invention. see figure 1 In this specific embodiment, the specific steps of a point-of-interest-oriented wayfinding sign layout method include:
[0047] S101. Extracting the indicating road network of the point of interest on the road network model;
[0048] S102. Define a path optimization index for measuring the convenience of the guiding path, the path optimization index includes path length, traffic flow and intersection turning;
[0049] S103. Traverse the indicated road network in the order of breadth first, calculate and dynamically update the path optimization index during the traversal process, and obtain the optimal guidance path in the indicated road network;
[0050] S104. Determine the content of setting guidance information and the location of setting guidance signs according to the optimal guidance...
