Fig. 2 is a flow chart illustrating a method for legacy cell screening in accordance with an example embodiment. The method 20 for screening an aging-suitable cell at least includes steps S202 to S210.
As shown in fig. 2, in S202, the geographical location of the cell to be evaluated is acquired.
In S204, a basic road network map and a service facility set are generated based on the geographic location. Taking the geographic position as a circle center, and extracting road vector information in a preset range to generate the basic road network map; and taking the geographic position as a circle center, and extracting service facilities in a preset range to generate the service facility set.
More specifically, the central point of the cell to be evaluated is taken as the center of a circle, and road vector information within a range of 2 kilometers around the cell is extracted to form a basic road network map. And information such as names, geographic coordinates, categories and the like of various service facilities within 2 kilometers around the cell to be evaluated can be extracted.
All facilities can be screened one by one according to the regulations of living circle supporting facilities in the urban residential area planning and design standard. The low relevance such as municipal utilities are cancelled in consideration of the relevance to the life of the old and the feasibility of acquiring network open source data; a community dining room with high demand for the old is increased; the park green land is used as a public service facility to be supplemented into the evaluation index, and the content which cannot be evaluated only by open source data is added into subjective evaluation, such as the construction conditions of a child activity field, a fitness facility, a household garbage collection point and the like. Finally, 5 types of 35 facilities are determined to participate in objective evaluation of community aging adaptation construction. The community suitable old facilities all need to meet one of the following conditions:
(1) The traditional Chinese medicine directly serves the daily life of the old, and is the type with the highest use frequency, such as: vegetable markets, parking lots, drugstores, and the like.
(2) The method provides targeted services for the elderly with limited self-care ability, such as: community dining halls, presidents, community retirement homes, etc.
(3) Indirectly related to the life of the old, is beneficial to improving the mental health of the old, such as: kindergarten, primary school, etc.
(4) Business and public service facilities that are somewhat less frequently used but are indispensable, such as: banking outlets, street offices, bus stations, etc.
Further, the facilities involved in objective assessment of community fitness construction are shown in table 1:
in S206, a facility index coverage rate, a facility accessibility degree, and a facility aging degree score of the cell to be evaluated are generated based on the basic road network map and the service facility set.
In one embodiment, a first life circle, a second life circle, a third life circle may be generated, for example, based on the base road network map; and dividing the service facilities in the service facility set into a first life circle service facility subset, a second life circle service facility subset and a third life circle service facility subset according to the geographic positions of the service facilities and the corresponding relation of the first life circle, the second life circle and the third life circle.
As shown in fig. 3, on the basis of the road vector diagram, each road that can be reached within the maximum walking radius set by the user and the shortest path distance to the end point of the road are calculated based on Dijkstra shortest path algorithm with the cell center point as the starting point, and the center points of the edge grids are connected into a continuous closed multi-segment line. In order to better aim at special conditions of the old, the average pace speed of the old is 1.00m/s as a main parameter, so that the polygonal range covered by the life circle for five minutes, ten minutes and fifteen minutes in the old-suitable cell is calculated.
In one embodiment, the facility index coverage for the cell under evaluation may be generated, for example, based on the first, second, and third sub-sets of life circle services. Details of the facility index coverage will be described in detail in the corresponding embodiment of fig. 4.
In one embodiment, the facility reachable convenience of the cell to be assessed may be generated, for example, based on the first sub-quantity, the second sub-quantity, the third sub-quantity, and their corresponding quantity weights. Details of facility accessibility are described in detail in the embodiment corresponding to fig. 5.
In one embodiment, a facility staleness score for the cell to be assessed may be generated, for example, based on the first sub-category, the second sub-category, the third sub-category, and the category weight corresponding to each category. Details of the facility longevity score are described in detail in the corresponding embodiment of fig. 6.
In S208, a composite assessment score is generated based on the facility index coverage, the facility reachability, and the facility staleness score. Generating objective scores based on the facility index coverage rate, facility accessibility and facility aging performance scores of the cell to be evaluated; generating a subjective score based on the barrier-free trip score, the activity site score and the plant landscape score corresponding to the cell to be evaluated; and generating the comprehensive assessment score based on the objective score and the subjective score.
In a specific embodiment, the barrier-free travel rating table, the activity site rating table and the plant landscape rating table can be generated based on a preset template; generating the barrier-free travel score, the activity site score and the plant landscape score based on filling results of a plurality of barrier-free travel score tables, activity site score tables and plant landscape score tables.
Among them, barrier-free is a basic condition for guaranteeing outdoor activities of the elderly. Particularly, the system can smoothly reach various leisure facilities and service facilities in a community aiming at people with inconvenient legs and feet or people needing to go out by means of wheelchairs, and is a subjective assessment on the accessibility of the path. The content covers road comfort, safety, identifiability and the like.
The leisure activity field is a field for providing various activities such as body building, chatting, playing cards, walking and the like for residents, and is a basic guarantee for meeting outdoor activities of the residents in a residential area. The questionnaire content gives consideration to the interests and hobbies of different old people and the requirements of the old people under different health conditions, and also considers the psychological needs and social communication needs of the old people.
The plant landscape is the basis for guaranteeing the quality of the ecological environment of the residential area, and abundant plant configuration is beneficial to physical and mental health of residents. The questionnaire content not only gives consideration to the ornamental abundance of plant landscape, such as four-season landscape, rich color and the like, but also reflects the attention to the use function, such as shading property, safety and the like. The level of post-maintenance of the plant landscape is also listed in the questionnaire as an important influencing factor.
The objective evaluation is based on open source big data, only the quantity and the position distribution of the reaction facilities are received, and the construction quality, the applicability and the like of the facilities cannot be reflected, so the subjective evaluation of the outdoor activity space elements is used as an important supplement for the aging evaluation. According to the research on the physiological, psychological and social requirements of the old, three main contents which are most closely related to the daily life of the old are determined: barrier-free travel, leisure activity places and plant landscape construction. In order to facilitate the participation evaluation of the old groups, the number of the questions is accurately reduced and refined, and the questions are set by selecting the factors which have the greatest influence on the outdoor activities of the old. Each topic can independently represent an evaluation level, so that the content intersection is avoided, and the topics are expressed in a concise and clear language as much as possible. As shown in FIG. 6, the user can slide the slider bar on the software interface to score the score in the range of 0-5, and finally count the score based on the percentile system.
In S210, when the comprehensive evaluation score meets a preset policy, the cell to be evaluated is taken as an adaptive old cell. The cell with the comprehensive score larger than the threshold value can be used as an age-adaptive cell for recommendation, and the cell can be recommended on the application home page for the user to select. And the basic method can also be used for evaluating all cells in the whole city range, generating scores and displaying the scores on an application end for a user to inquire.
It is worth mentioning that the present application has been described by taking an adaptive cell as an example, but the specific method of the present application may also be used for a user to perform other cell screening, and set different points of interest to screen other types of cells. Such as a cell suitable for children's activities, a cell suitable for white-collar residences, etc., although the application is not limited thereto.
According to the method for screening the suitable old community, the geographical position of the community to be evaluated is obtained; generating a basic road network map and a service facility set based on the geographic position; generating a facility index coverage rate, facility accessibility and facility aging score of the cell to be evaluated based on the basic road network map and the service facility set; generating a comprehensive evaluation score based on the facility index coverage rate, the facility accessibility degree and the facility aging degree score; when the comprehensive evaluation score meets a preset strategy, the community to be evaluated is used as an aged-suitable community, the aged-suitable community meeting the user requirements can be quickly and accurately screened out, comprehensive systematic diagnosis and evaluation can be carried out on urban construction, and the advantages and short boards of the community in the aged-suitable construction aspect can be quickly diagnosed.
Furthermore, the screening method for the suitable old community adopts an evaluation mode combining subjective evaluation and objective analysis, and has the following advantages:
the application of the information service technology in the urban construction field can be fully exerted by an objective evaluation mode, and the accuracy and convenience of the aging evaluation are improved. Based on open source data such as urban roads and POI (Point of interest), the community suitability is evaluated. The open source data has the characteristics of large data volume, quick response requirement, various data types and the like; the evaluation is carried out by utilizing the open source data, a large number of communities can be quickly and accurately evaluated in a short time, and a large amount of time, manpower and material resources spent in the traditional manual research process are avoided. This will allow the evaluation process to be performed efficiently.
An isochronal range is defined based on the path distance. The traditional method for dividing the equal-time circle range by space analysis often directly uses the radius of a buffer area for dividing. The demarcation mode is too simple to the real city space, and can not reflect the actual equal time circle range. The method for calculating the equal time circle accurately depicts the space range related to the equal time circle based on the path distance of the urban road network, and enables the evaluation of the community suitable and old facilities to be more accurate.
The evaluation of the public service facilities takes into account both the completeness of the facility category and the importance and the number of outfits of the different facilities. The community longevity and convenience evaluation is more scientific, complete and comprehensive, and users can observe advantages and loopholes of public facilities of various communities more conveniently, so that subsequent targeted decisions of the users can be facilitated.
The subjective evaluation mode makes up the limitation of objective evaluation, and obtains an individualized evaluation result according to the construction and use level of the reaction facilities with more real human scale and the user satisfaction and the individual specific conditions of the user. The subjective and objective combination can ensure that the evaluation result is more instructive to the updating and the reconstruction of the community in the next step. In two adjacent cells, the objective evaluation results aiming at the supporting facilities are likely to be very similar, and the subjective evaluation can truly reflect the actual construction level of the outdoor space of the cell.
The research results are visually expressed by utilizing an information technology, so that the method is convenient for common public operation and use. The network environment limitation of software application is also considered, the equal-time-circle algorithm is built in the platform, and API calling for map services such as Mapbox is avoided. The frequent access to a third-party platform interface is avoided, the network delay is reduced, and the demands of a user for calculating time circles and the like can be quickly responded; meanwhile, the problems of copyright, service calling charge and the like are avoided, and the software development cost and the legal risk are reduced.
Furthermore, the aged-suitable cell screening method is different from an urban physical examination evaluation system which takes professional comprehensive characteristics, takes a detailed evaluation list and evaluation rules as supports, and mainly faces urban managers and professionals to carry out comprehensive systematic diagnosis and evaluation on urban construction. The method is based on the common public as a starting point, and a high-efficiency, convenient and practical community aging assessment tool is established. A professional and scientific evaluation system is presented by visual and easily-operated computer software, and research results are converted into a software tool for serving social life.
Software generated by the method in the application can be used for evaluating whether a certain cell can meet the self-old-age need. The elderly can influence the subjective evaluation part according to the health condition and personal preference, so that the personalized evaluation result can be obtained.
The community manager can quickly evaluate the generalization of the aging-adapted construction of a certain cell through the software generated by the method in the application without professional training, quickly diagnose the advantages and short boards of the cell in the aging-adapted construction aspect, and clearly improve the content and the next working key point. After the transformation is finished, the evaluation is carried out again, and the result comparison before and after the transformation can visually reflect the transformation effect.
Software generated by the method can be used as one of investigation means when professional planning designers carry out community transformation, and by utilizing open source big data, investigation speed and accuracy can be effectively improved, and working efficiency is greatly improved.
It should be clearly understood that this application describes how to make and use particular examples, but the principles of this application are not limited to any details of these examples. Rather, these principles can be applied to many other embodiments based on the teachings of the present disclosure.
Fig. 4 is a diagram illustrating a method of legacy cell screening according to another example embodiment. As shown in fig. 4, the types and the numbers of the services of the respective circle layers are counted for each of the three life circle ranges, and table 2 is generated as follows, and it is clear from table 2 which services are still lacking.
And comparing the report with a complete facility summary table, further calculating to obtain index coverage rate of the suitable old facilities, taking the index coverage rate as an evaluation index of the level for evaluating the perfection degree of the suitable old facilities in the suitable old community, and finally performing visual expression to facilitate the public to understand the index meaning. The specific calculation formula is as follows:
the number of types of facilities in a 5-minute living circle/15 = index coverage rate of matched facilities in the 5-minute living circle;
index coverage rate of facility type number/(15 + 8) = 10-minute living circle supporting facility index in 5-minute + 10-minute
5 min +10 min +15 min facility type number/(15 +8+ 12) =15 min supporting facility index coverage rate.
Wherein, the 5 minute life circle corresponds to A-type facilities, the 10 minute life circle corresponds to A-type facilities and B-type facilities, and the 15 minute life circle corresponds to A-type facilities, B-type facilities and C-type facilities. In a specific embodiment, class a facilities correspond to a weight of 15, class B facilities correspond to a weight of 8, and class C facilities correspond to a weight of 12.
Fig. 5 is a diagram illustrating a method for legacy cell screening according to another example embodiment. As shown in fig. 5, considering that the population living and caring for the elderly is mainly in a walking trip mode, the distance between the facility and the residential area is a main factor affecting the convenience of trip, and therefore, the distance is used as a weighting factor for measuring the convenience.
Convenience index calculation formula Q i ＝∑ i＝1 b i_j // Ns where Q i Is convenience index of ith cell, b i_j The j is the j-type factor of the ith cell, j is the circle layer (distance) weight factor, and Ns is the total amount of facilities.
In a specific embodiment, according to the division result of the facility circle layer, the scoring opinion of the experts and the travel rule of the old, the weight of the distance between facilities in the 5-minute living circle is 10, the weight of the distance between facilities in the ten-minute circle layer is 8, and the weight of the distance between facilities in the 5-minute circle layer is 6.
Sigma, assuming that the total amount of facilities in the five-minute circle around a certain cell is alpha, the total amount in ten minutes is beta, and the total amount in fifteen minutes is gamma i＝1 b i_j = (10 α +8 β +6 γ), convenience index Q i ＝(10α+8β+6γ)/(α+β+γ)。
Fig. 6 is a diagram illustrating a method of legacy cell screening according to another example embodiment. As shown in FIG. 6, the age-adapted index is calculated by the formula T i ＝∑ i＝1 s i_j In the formula Q i Is age index of ith cell, s i_j And j is an aging suitability weight factor in the age suitability evaluation, and the assignment of the aging suitability weight integrates the physical activity ability of the old and the frequency of daily trip destination service facilities, the comprehensive experts score, and different aging suitability weight scores are determined for different service facilities.
The distribution circle layer of the facilities is not considered for the computer weight distribution of the service facility aging suitability, so that the similar facilities in different circle layers are combined, the retrieval of the acquired data POI is considered, the use convenience of the old people is integrated, the scales of the similar facilities are not distinguished any more, and the category of the facilities is searched for 32 types after the 39 images in the list of the suitable facilities in the life circle in 15 minutes are classified and combined.
Assuming that the type of the services involved in the 15-minute circle around a certain cell is NZ type, the weight corresponding to each type of the services is Ni (i =1,2,3, 4)\8230, 8230, 8230i) is suitable for the old index sigma i＝1 s i_j ＝(N1+N2+N3+………N)。
