Embodiment Construction
[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0019] figure 1 It is a schematic diagram of the distribution of street sign nodes in the scenic area of the present invention, including street sign nodes s, 1, 2, 3, ..., e in the scenic area. Take road sign nodes s, 1, 3, and e as an example, when time and congestion degree are jointly constrained, the value is 35, and the congestion degree of each road section passed is evaluated as 1, 1, 2 respectively (the values that have not passed are all 0, and the rest are 0 The distribution to 1 is divided into five grades), then the score at this time is 35+1+1+2=39; take one-fifth of the sum of the maximum flow of people passing through all road sections as the setting grade evaluation, for example The above s, 1, 3, e correspond to the maximum flow of people that can accommodate 100, 150, 150 respectively, then the evaluation stan...

The invention relates to a scenic area route guide plan-based mathematical method. According to the method, time serves as a mathematic model of a constraint condition, congestion degree serves as a mathematic model of the constraint condition, and the time and the congestion degree serve as a mathematic model of a multi-target constraint condition, wherein foot passenger distribution of each roadsection in the mathematic model taking the congestion degree as the constraint condition is solved by a method that a necessary point exists in the scenic area, the problem of the congestion degree at each road section can be solved through foot passenger distribution, and real-time distribution of the congestion degree can be solved conveniently. The problem of the total passenger flow rate in two points is solved by a two-point type necessary guide board, and the total passenger flow rate is distributed in real time based on the length of the route in the two points. The scenic area route planning is realized by a mathematic method taking the time and the congestion degree as unit target constraint conditions, and the method is simple to operate.
Description
technical field [0001] The invention relates to the field of mathematical models for path planning of scenic spots, in particular to a mathematical method based on path guidance and planning of scenic spots. Background technique [0002] At present, there are many methods for path planning of scenic spots, and these methods are often relatively one-sided. Usually, the general planning path is planned with time as the main reference factor, which makes the planning of the scenic spot path unreasonable. When people choose a scenic spot, they mainly refer to the satisfaction, popularity and time of the scenic spot, but it is difficult to artificially control the popularity of the scenic spot, so the satisfaction and time will be used as a reference. Contents of the invention [0003] In order to solve the shortcomings of the above-mentioned model, the present invention provides a mathematical method based on route planning of scenic spots. The mathematical method based on ro...
