As shown in fig. 2, the method for analyzing the influence of the parking guidance screen based on the GIS on the illegal parking behavior mainly includes the following steps:
step 1:
(1) Acquiring distribution data of parking guidance screens in salt city, wherein the distribution data comprise distribution positions and distribution quantity of a primary guidance screen, a secondary guidance screen and a tertiary guidance screen;
(2) Acquiring historical illegal parking data of 2021 month 6 to 2022 month 6 in the salt city, wherein the historical illegal parking data comprise the number of illegal parking times and longitude and latitude data of the position of an illegal parking intersection;
step 2:
(1) Inputting longitude and latitude information of distribution positions of induction screens of all levels of the salt city, longitude and latitude data of positions of illegal parking intersections of the salt city and illegal parking times information obtained in the step 1, and establishing a distribution map of the induction screens of all levels of the salt city and the illegal parking based on a GIS;
(2) Setting service ranges of the first, second and third induction screens, namely 3km, 1.5km and 0.5km, based on different installation positions of the induction screens at all levels, namely that the first induction screen is arranged on a main road, the second induction screen is arranged on a secondary road and the third induction screen is arranged on the periphery of a parking lot;
(3) Selecting a position point of a salt city illegal parking intersection, and respectively constructing a first buffer area, a second buffer area and a third buffer area of each illegal parking point of the salt city by taking the service ranges of the first, second and third guidance screens as buffer area radiuses and the illegal parking position as a buffer center;
(4) The distribution map of the salt city illegal parking road mouth buffer area and each level of induction screens is connected, as shown in figures 3, 4 and 5, the number of each level of induction screens of each illegal parking point under different buffer radiuses is further established, and the number of each level of induction screens in each buffer area is measured and calculated as follows:
first-level induction screen
Wherein A represents the distribution quantity of the first-level induction screens in the buffer area, and i is the number of the first-level induction screens in the analysis area;
second-level induction screen
Wherein B represents the distribution quantity of the secondary induction screens in the buffer area, and j is the number of the secondary induction screens in the analysis area;
three-stage induction screen
Wherein, C represents the distribution number of the three-level induction screens in the buffer area, and k is the number of the three-level induction screens in the analysis area.
Step 3:
(1) According to the result of the step 2, constructing a corresponding relation table between the distribution quantity of each level of induction screens and the quantity of illegal parking behaviors by using the measured distribution quantity of each level of induction screens in each buffer zone;
(2) Dividing the number of illegal parking into two samples by taking a median as a demarcation point, setting a check field as the distribution number of each level of induction screens by using a non-parameter check method of an independent sample, and calculating the statistical significance relation between the distribution number of each level of induction screens in the buffer area and the number of illegal parking.
As shown in fig. 3-5, the map is divided into various levels of guidance screens and illegal parking buffer areas in the salt city, wherein the more the number of illegal parking is, the higher the histogram is.

TABLE 1
* p.ltoreq.0.05, is significant in the 95% confidence interval.
As shown in Table 1, the statistical significance relation table of the distribution quantity of the induction screens at all levels and the number of illegal parking times shows that the first-level induction screen and the third-level induction screen have no significance influence on the illegal parking behaviors, and the second-level induction screen has significance influence on the illegal parking behaviors. According to the statistical significance relation, the conclusion can be drawn that the influence of the first-level induction screen and the third-level induction screen on the illegal parking behavior is relatively small, and the arrangement of the second-level induction screen can effectively influence the illegal parking behavior, so that the number and the arrangement positions of the second-level induction screens are required to be researched, and the illegal parking behavior is effectively reduced. In this example, the first-level guidance screen is generally disposed on the main road and is far from the parking lot, so that the influence on the illegal parking behavior near the distribution point is not great; the three-level induction screen is generally arranged at the periphery of the parking lot, so that the decision of parking is greatly influenced by personal factors of a driver; the secondary guidance screen is generally arranged on the secondary road, the accessibility is higher, and the parking will of a driver is more definite, so that the illegal parking behavior can be reduced. Therefore, the results of the present embodiment are realistic and have wide applicability.

the significance relation calculation module is used for respectively obtaining the number of parking guidance screens in the primary buffer zone, the secondary buffer zone and the tertiary buffer zone according to the distribution maps of parking guidance screens at all levels and illegal parking, and obtaining significance relation between the illegal parking points in the primary buffer zone, the secondary buffer zone and the tertiary buffer zone and the parking guidance screens at all levels according to the number of parking guidance screens in the primary buffer zone, the secondary buffer zone and the tertiary buffer zone;
according to the distribution maps of parking guidance screens at all levels and illegal parking, the number of the parking guidance screens in the primary buffer area, the secondary buffer area and the tertiary buffer area is respectively obtained, and the method comprises the following steps:
distribution number of first-level induction screens in buffer zoneWherein i is the number of the first-level induction screen in the analysis area;
distribution number of secondary induction screens in buffer zoneJ is the number of the secondary induction screen in the analysis area;
three-level induction screen distribution number in buffer zoneWherein k is the number of the three-level induction screen in the analysis area; according to the number of parking guidance screens in the primary buffer zone, the secondary buffer zone and the tertiary buffer zone, the salient relationship between the illegal parking points in the primary buffer zone, the secondary buffer zone and the tertiary buffer zone and the parking guidance screens at all levels is obtained, and the method specifically comprises the following steps:
constructing a corresponding relation table between the distribution quantity of each level of parking guidance screens and the quantity of illegal parking behaviors by utilizing the distribution quantity of each level of parking guidance screens in each buffer area, wherein each buffer area comprises a first buffer area, a second buffer area and a third buffer area, and each level of parking guidance screens comprises a first level parking guidance screen, a second level parking guidance screen and a third level parking guidance screen;
dividing the number of illegal parking times into two samples by taking the median of the number of illegal parking times as a demarcation point, setting a check field as the distribution number of all levels of parking guidance screens by using a non-parameter check method of an independent sample, and calculating to obtain the statistical significance relation between the distribution number of all levels of parking guidance screens in each buffer area and the number of illegal parking times.
