For the convenience of understanding the embodiments of the present invention, the following description will be further explained by taking several specific embodiments as examples in conjunction with the drawings, and the embodiments are not to be construed as limiting the embodiments of the present invention.
Example one
The embodiment of the invention divides the interaction process of the passenger and the station guide mark into three stages of perception, identification and decision, and analyzes the characteristics of each stage according to the interaction influence factors between the passenger and the station guide mark, and the installation position and the angle of the station guide mark are variables influencing the interaction between the passenger and the mark. Therefore, the invention needs to establish an addressing model and solve the installation position and angle of the station guide identifier at the same time.
The processing flow of the installation design method of the station guide mark provided by the embodiment of the invention is shown in fig. 1, and comprises the following processing steps:
step S10: and constructing a station distributed network based on the structural characteristics of the stations.
In the station design process, the passenger flow streamline design is completed before the identification design. However, unlike road traffic, clear passing lines are not laid in subway station halls and platforms for the convenience of passengers. Although the flow direction of the passenger flow is basically determined, the walking direction of the passengers in a specific space has great randomness. Therefore, the scheme provides a station distributed networked representation method based on the determined passenger flow streamline organization. The station distributed network can clearly describe the passenger flow, provides convenient walking paths for passengers according to the shortest path algorithm, restricts the location selection space of the guiding identification and simplifies the design problem of the identification system.
Fig. 2 is a schematic diagram of a station distributed network construction based on maklink according to an embodiment of the present invention. The building process of the station distributed network comprises the following steps:
the first step is as follows: based on the structural characteristics of the station, the maklink method is adopted to connect the vertexes of the station obstacles, as shown by the dotted line in fig. 2. The Maklink vertex joining principle is to join the vertex of each obstacle in the station building structure with the closest vertex of the adjacent obstacle.
The second step is that: and selecting the middle point of each maklink connecting line as a passenger path point, and calculating the shortest path of the passenger flow OD. The route connecting point 1, point 2, point 3, point 4 and point 5 as shown in fig. 2 is the OD shortest path for the traffic from point 1 to point 5. Then, the set of all OD shortest paths constitutes the station passenger flow OD distribution network. The passenger needs to change the traveling direction at each point, so that the guiding requirement is generated, guidance needs to be carried out at the points, and the middle point of each maklink edge can effectively avoid the obstruction of the sight line of the passenger by the obstacle. However, the guidance range of the guidance markers may be larger than the distance between turning points of adjacent paths, and therefore, the optimal number and positions of the markers still need to be solved by establishing an addressing model.
Step S20: an identification site selection space is established based on a station passenger flow OD distributed network, parameters related to a passenger and identification interaction model are determined under the constraint of the identification site selection space, and the passenger and identification interaction model is established based on the parameters.
By establishing a station distribution network, we can constrain or limit the identification addressing space. Defining decision variables under the constraint of identification address space

Comprises the following steps: if the mark with the installation angle alpha is set at s
Figure GDA0002736145560000062
Otherwise, the reverse is carried out
Figure GDA0002736145560000063
s is a point in the station-wide network. The interaction between the passenger and the identification is mainly divided into three stages of sensing identification, identifying guide information and making direction decision. Whether the indicia is within the field of view of the occupant is an important factor in determining whether the occupant will perceive the presence of the indicia.
Fig. 3 is a schematic view of a passenger sensing indicator according to an embodiment of the present invention, as shown in fig. 3, a black arrow indicates that a passenger faces toward or walks, a passenger view angle is k, and an indicator a is within a passenger view range, so that the passenger can sense the presence of the indicator a during walking; the passenger cannot, on the contrary, perceive the presence of the identification B.
Let the coordinates of passenger p and identification s in the station distribution network be (x)p,yp),(xs,ys) The upstream point coordinate of the p-way path of the passenger is

then
Figure GDA0002736145560000077
After the passenger perceives the identification, the passenger needs to recognize the identification information. Whether the passenger can recognize the identification information is mainly determined by the visual field of the identification. Previous identification layout design models have assumed either a circular or regular sector shape of the visible field. However, the passenger's perception of the identification is affected not only by distance, but also by viewing angle and obstacles. Therefore, the embodiment of the invention adopts the identification visible area calculation method to calculate the identification guide range. Fig. 4 is a schematic diagram of a visible identification field according to an embodiment of the present invention, as shown in fig. 4, the size of the minimum information unit of the CX signboard, such as the length of a letter or a chinese character. Let b be CX/2, and phi be the included angle between PC and PX. Identifying the visual field boundaries may be expressed as:

the installation angle α is an angle at which the sign rotates clockwise from a position horizontal to the x-axis in a plan view along the center of the guide sign.
Fig. 5 is a schematic distance diagram of an obstacle and a passenger and a sign according to an embodiment of the present invention, and as shown in fig. 5, when an obstacle (such as a beam column, a staircase, etc.) exists between the passenger and the sign, the sign cannot guide the passenger due to the view obstruction. The coordinates of the obstacle b are (x) respectivelyb,yb) Then the distance of the obstacle from the passenger and the identification connection line is:

After the passenger identifies the identification information, a decision needs to be made according to the identification guidance information, however, the identification guidance direction is limited, and fig. 6 is a schematic diagram of the identification guidance arrow indicating the direction and guiding the passenger provided by the embodiment of the invention, as shown in fig. 6. The next point in the path of passenger p must satisfy the constraint of the guidance direction indication capability of sign s, before sign s can guide passenger p. As shown in FIG. 6, if the next waypoint for passenger p is p1Then the identification s cannot guide the passenger p to the position p1But can reach p2,p3,p4.
