Description

Technical Field

[0001] The present invention relates to the technical field of road planning, and in particular to a road planning method and device based on rural tourism routes. Background Art

[0002] With the increasing popularity of rural tourism, how to scientifically and rationally plan tourist routes to maximize tourists' sightseeing experience while minimizing interference with the ecological environment and residents' lives has become a technical problem that needs to be solved urgently. At present, the planning of most rural tourist routes only relies on manual experience or simple path optimization algorithms, and fails to fully consider the comprehensive influence of multiple factors. This kind of planning often leads to unscientific and unreasonable tourist route planning, poor tourist experience, and even damage to the ecology. In this context, the use of genetic algorithms for tourist route planning can simultaneously consider multiple optimization objectives and find the tourist route plan with the best comprehensive effect through iterative evolution. However, the existing genetic algorithms used in rural tourist route planning often do not fully combine geographical and ecological information, making it difficult to achieve satisfactory planning results.

[0003] In the prior art, the authorization announcement number CN114896523B discloses a road planning method and device based on rural tourism routes, which receives multiple rural location information of interest to users, and respectively searches for rural cultural information corresponding to each rural location information, generates rural tourism routes according to the dynasty types corresponding to the rural location information and the rural cultural information, and counts the network traffic of the rural tourism routes, calculates the pedestrian flow based on the network traffic, and plans roads for rural locations of the rural tourism routes according to the pedestrian flow, thereby reducing travel congestion.

[0004] The main problems with the above method are: although generating tourist routes based on rural cultural information and dynasty types is helpful for cultural inheritance, it will ignore other non-cultural attractions, resulting in the generated routes being not comprehensive enough; and when planning roads, it mainly focuses on network traffic and pedestrian flow, while ignoring the interference of rural tourism on the ecological environment and residential areas, which may lead to the destruction of the ecological environment or adverse effects on residents' lives during tourism. The above scheme does not have any management or mitigation measures for these impacts.

[0005] The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not constitute the prior art that is already known to one of ordinary skill in the art. Summary of the invention

[0006] The purpose of the present invention is to provide a road planning method and device based on rural tourism routes to solve the problems raised in the above background technology.

[0038] The present invention also provides a road planning device based on a rural tourism route, which is used to implement the above-mentioned road planning method based on a rural tourism route, and specifically includes:

[0053] Example:

[0054] See also Figure 1 , the present invention provides a technical solution:

[0055] A road planning method based on rural tourism routes, the specific steps include:

[0056] Step 1: Obtain the geographical location data of all tourist spots, landscape nodes, ecologically sensitive areas and residential areas in the target tourist area through the geographic information system, and establish a plane rectangular coordinate system in the target area;

[0057] In this embodiment, the principle for establishing a plane rectangular coordinate system in the target area is:

[0058] After obtaining the geographical location points of all tourist spots, landscape nodes, ecologically sensitive areas and residential areas in the target area through the geographic information system, a plane rectangular coordinate system is established with the geographical location points in the bottom row as the horizontal axis and the geographical location points in the leftmost column as the vertical axis to ensure that each tourist spot, landscape node, ecologically sensitive area and residential area has a unique coordinate. In addition to the four main optimized parameters, other location data correspond to one coordinate in the coordinate system.

[0059] Step 2: Determine two tourist points on the road to be planned, and generate multiple different paths connecting the two points, divide the paths into several short-distance path segments, and generate the total travel time of the path based on the time required to pass the path segments;

[0060] In this embodiment, the principle for generating the total travel time of the path is:

[0061] Based on the length of the path segment and the average vehicle speed on the path segment, the travel time of the path segment is generated, and the calculation formula is as follows:

[0062]

[0063] Among them, T i,j is the travel time of the jth path segment in the i-th path, i is the index of the path, and i = 1, 2, ..., n, n is the total number of paths, j is the index of the path segment on the path, and j = 1, 2, ..., M i , M i is the total number of path segments on the i-th path, S i,j is the length of the jth path segment in the i-th path, v i,j is the average vehicle speed on the jth path segment in the i-th path;

[0064] The length of the path segment is obtained by the distance measurement software, and the average vehicle speed on the path segment is the average speed of vehicles passing through the path in the historical data;

[0065] The total travel time for a route is generated based on the travel time of the route segments, according to the following formula:

[0066]

[0067] T i is the total travel time of the ith path, the total travel time T i It reflects the time spent on the journey between two tourist spots. It is composed of the sum of the time of several path segments. The total travel time is proportional to the length and number of path segments, and inversely proportional to the average driving speed.

[0068] Step 3: Generate the total landscape value of the path based on the landscape node data on the path segment;

[0069] In this embodiment, the principle for generating the total landscape value of the path is:

[0070] For each path segment, the number of landscape nodes passed by the path segment is identified. The total landscape value of the path is the sum of the number of landscape nodes passed by the path segment, based on the formula:

[0071]

[0072] Among them, S i represents the total landscape value of the i-th path, j represents the index of the path segment, and m i,j Represents the number of landscape nodes on the jth path of the ith path.

[0073] The total landscape value of a path reflects the number of landscape nodes passed through on the path, which can be read directly in the coordinate system. For each path segment, the landscape nodes contained in the path segment are read out separately. The sum of the landscape nodes of all path segments is the total landscape value of the corresponding path.

[0074] Step 4: Generate the ecological disturbance intensity of the path based on the number of ecologically sensitive areas on the path segment, the length of the path segment passing through the ecologically sensitive areas, and the length of the path segment. The ecologically sensitive areas include: vegetation protection areas, water source protection areas, wildlife habitats, nature reserves, wetlands, and forests.

[0075] In this embodiment, the formula for generating the ecological interference intensity of the path is:

[0076]

[0077] Among them, E i,j represents the ecological disturbance intensity of the jth path segment of the i-th path, A represents the number of ecologically sensitive areas that the path segment passes through, r represents the influence weight of the number of ecologically sensitive areas that the path segment passes through on the ecological disturbance intensity, S' i,j represents the length of the jth path segment of the i-th path in the ecologically sensitive area, S i,j represents the length of the jth path segment of the i-th path, E i Represents the ecological disturbance intensity of the i-th path. The ecological disturbance intensity reflects the impact of path selection on ecologically sensitive areas. It is determined by the number of ecologically sensitive areas passed by the path segment and the coverage of the ecologically sensitive areas by the path segment. The two have the same importance, so r = 0.5. The ecological disturbance intensity of all path segments is added to generate the ecological disturbance intensity of the entire path. The ecological disturbance intensity is proportional to the number of ecologically sensitive areas passed by the path and the length passed in the ecologically sensitive areas.

[0078] Step 5: Generate the residential interference intensity of the path based on the number of residential areas on the path segment, the length of the path point passing through the residential area, and the length of the path segment; in this embodiment, the formula for generating the residential interference intensity of the path is:

[0079]

[0080] Among them, F i,j represents the resident interference intensity of the jth path segment of the ith path, B represents the number of residential areas that the path segment passes through, k represents the influence weight of the number of residential areas that the path segment passes through on the resident interference intensity, S” i,j S represents the length of the jth path segment of the i-th path in the residential area. i,j Represents the length of the j-th path segment of the i-th path.

[0081] The resident interference intensity reflects the impact of path selection on residential areas. It is determined by the number of residential areas passed by the path segment and the coverage of the residential areas by the path segment. The two have the same importance. Therefore, k = 0.5. The resident interference intensity of all path segments is added to generate the resident interference intensity of the entire path. The resident interference intensity is proportional to the number of residential areas passed by the path and the length passed in the residential areas.

[0082] Step 6: Generate the fitness value of each path based on the total travel time, total landscape value, ecological disturbance intensity and resident disturbance intensity of the path;

[0083] In this embodiment, the formula for generating the fitness value is:

[0084] The formula for generating the comprehensive fitness function is:

[0085]

[0086] Among them, H represents the fitness value, T represents the travel time, S represents the landscape value, E represents the ecological disturbance intensity, F represents the resident disturbance intensity, w1, w2, w3, and w4 represent the influence weights of the travel time, landscape value, ecological disturbance intensity, and resident disturbance intensity, respectively, w1+w2+w3+w4=1, and w2>w1>w3>w4;

[0087] The fitness value is an evaluation index for road planning, which reflects the simultaneous satisfaction of the road planning scheme with the four optimization goals of shortest travel time, maximum landscape value, minimum ecological interference and minimum resident interference. The weight of each goal is adjusted through the specific values ​​of the four optimization goals to achieve stage feedback. The greater the fitness, the more the road planning scheme meets the requirements and the more priority it is output; the value of the fitness function is inversely proportional to the travel time, directly proportional to the landscape value, and inversely proportional to the intensity of ecological interference and the intensity of resident interference. In the process of rural tourism, the top priority is the experience of playing, so the landscape value accounts for the highest proportion, followed by travel time, ecological interference and resident interference. The weights of the four optimization goals can be: w1=0.3, w2=0.35, w3=0.25, w4=0.1.

[0088] Step 7: The path corresponding to the maximum fitness value is taken as the optimal path between the two tourist points of the road to be planned.
