[0046] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0047] Currently, five methods are mainly used to calculate urban parking demand in China, i.e., urban population scale, urban land scale, motor vehicle ownership, traffic policy and motor vehicle OD prediction. The researches on parking space optimization at home and abroad mainly include (1) the influence of roadside parking behavior on traffic (2) improving parking space turnover rate through management strategies to reduce the influence on road traffic (3) optimizing parking scheme in urban central business district. However, the current research method mainly evaluates and plans parking lot construction in the whole region, and there is no evaluation method for the rationality of parking space configuration of the built parking lot and whether the number of parking spaces meets the current parking demand. With the increase of motor vehicle ownership, the built parking lot needs to be reevaluated periodically whether the number of parking spaces meets the current parking demand.

[0048] In the present embodiment, an evaluation method for the number of parking spaces of a roadside parking lot is provided, which can be used in electronic devices such as computers, mobile phones, tablet computers and the like. Figure 1 is a flowchart of the evaluation method for the number of parking spaces of a roadside parking lot according to an embodiment of the present application. As shown in Figure 1 , the flowchart includes the following steps:

[0049] S11, acquire the number of parking spaces, parking data and calculation period of the built roadside parking lot in the region. In this embodiment, the number of parking spaces, parking data (statistical period is every day) and calculation period (set according to actual needs, which can be a week, a month, etc.) of the built roadside parking lot in the preset region are acquired by using the existing data acquisition technology. It should be noted that the acquired data is acquired by using the existing acquisition equipment and acquisition technology, and the embodiment is not limited in this regard.

[0050] S12, calculate the parking space utilization rate and the parking space length proportion of the parking lot according to the number of parking spaces, the parking data and the calculation period. Details will be described in subsequent steps, and the embodiment will not be described here.

[0051] S13, determine whether the parking space utilization rate and the parking space length proportion meet the preset condition, and determine the determination result. When the parking space utilization rate and the parking space length proportion do not meet the preset condition, it is determined that the number of newly added parking spaces m is 0, and no parking space setting recommendation strategy for the parking lot is generated this time. The data can be run fixedly every month to evaluate whether the current number of parking spaces meets the parking demand. It should be noted that the embodiment takes one month as a period for calculation, and the period can be set according to needs in actual application, and the embodiment is not limited in this regard. Details will be described in subsequent steps, and the embodiment will not be described here.

[0052] S14, determine the number of newly added parking spaces according to the determination result. Details will be described in subsequent steps, and the embodiment will not be described here.

[0053] The evaluation method for the number of roadside parking lot spaces provided in this embodiment calculates the number of newly added parking spaces of the built parking lot through the parking space length and the running efficiency index, evaluates the rationality of the configuration of the parking spaces of the built urban roadside parking lot and whether the number of parking spaces meets the current parking demand, ensures that the parking demand increases with the increase of the number of cars, and ensures that the parking lot construction can meet the parking demand. Thus, the problem of road congestion, travel difficulty and parking difficulty is alleviated. The current number of parking spaces of the built parking lot is recalculated and evaluated at a fixed period, which provides a basis for judging the planning of parking spaces.

[0054] In another embodiment, an evaluation method for the number of roadside parking lot spaces is also provided. According to another flow of the evaluation method for the number of roadside parking lot spaces of the embodiment, the flow includes the following steps:

[0055] S21, acquire the number of parking spaces, parking data and calculation period of the built roadside parking lot in the region. Details are described in step S11, and the embodiment will not be described here.

[0056] S22, calculate the parking space utilization rate and the parking space length ratio of the parking lot according to the number of parking spaces, the parking data and the calculation period.

[0057] Specifically, the step S22 further comprises the following steps:

[0058] S221, calculate the parking space utilization rate of the parking lot by dividing the product of the calculation period and the parking data by the sum of the number of parking spaces; calculate the parking space utilization rate of the parking lot according to the parking record. n is the calculation period, which is a specific number of days. The formula is: parking space utilization rate (daily turnover rate) = parking data * n / (n1 parking space number + n2 parking space number + n3 parking space number + … (i.e. the sum of the number of parking spaces of all parking lots in the region)).

[0059] S222, obtain the parking space distribution type, parking space form and current road length of the parking lot. Specifically, the parking space distribution type includes: single-side distribution and double-side distribution; the parking space form includes: road-side parallel form and road-side vertical form.

[0060] S223, calculate the parking space length ratio according to the parking space distribution type, the parking space form and the current road length. The single-side distribution, the double-side distribution, the road-side parallel form and the road-side vertical form are combined and calculated by using the current road length to determine the parking space length ratio.

[0061] (1) When the parking lot is single-side distribution and road-side parallel form, the parking space length ratio is 6.5 times the number of parking spaces divided by the current road length; that is: parking space length ratio = current number of parking spaces * 6.5 / current road length (m).

[0062] (2) When the parking lot is single-side distribution and road-side vertical form, the parking space length ratio is 2.5 times the number of parking spaces divided by the current road length; that is: parking space length ratio = current number of parking spaces * 2.5 / current road length (m).

[0063] (3) When the parking lot is double-side distribution and road-side parallel form, the parking space length ratio is 6.5 times the number of parking spaces divided by 2 times the current road length; that is: parking space length ratio = current number of parking spaces * 6.5 / (current road length (m) * 2).

[0064] (4) When the parking lot is double-side distribution and road-side vertical form, the parking space length ratio is 2.5 times the number of parking spaces divided by 2 times the current road length; that is: parking space length ratio = current number of parking spaces * 2.5 / (current road length (m) * 2.

[0065] S23, determine whether the berth utilization rate and the berth length proportion meet preset conditions to determine a determination result. The preset conditions are that the berth utilization rate of the previous calculation period of the current parking lot is greater than 60.0%, and the berth length proportion is less than 70.0%. For details, refer to step S13, which will not be repeated in the embodiment.

[0066] S24, determine the number of newly added berths according to the determination result. For details, refer to step S14, which will not be repeated in the embodiment.

[0067] In another embodiment, an evaluation method for the number of berths of a roadside parking lot is also provided. The evaluation method for the number of berths of the roadside parking lot according to the embodiment of the application includes the following steps:

[0068] S31, obtain the number of berths of a built roadside parking lot in a region, parking data, and a calculation period. For details, refer to step S21, which will not be repeated in the embodiment.

[0069] S32, calculate the berth utilization rate and the berth length proportion of the parking lot according to the number of berths, the parking data, and the calculation period. For details, refer to step S22, which will not be repeated in the embodiment.

[0070] S33, determine whether the berth utilization rate and the berth length proportion meet preset conditions to determine a determination result. For details, refer to step S23, which will not be repeated in the embodiment.

[0071] S34, determine the number of newly added berths according to the determination result.

[0072] In the embodiment, the step S34 further includes the following steps:

[0073] S341, when the determination result meets the preset conditions, calculate the operation efficiency and the berth construction potential value of the parking lot;

[0074] S342, determine the minimum value of the operation efficiency and the berth construction potential value as the number of newly added berths. The number of newly added berths of the parking lot is m, where m = min(p, r), and the minimum value is rounded down. p is the operation efficiency of the parking lot, and r is the berth construction potential value.

[0075] Specifically, the operation efficiency of the parking lot is calculated, including: the number of berths multiplied by the berth utilization rate of the previous calculation period, and then divided by 60%. That is: p = (the number of berths of the parking lot currently * the berth resource utilization rate of the previous calculation period) / 60%.

[0076] The berth construction potential value r includes:

[0077] When the parking lot is single-side distribution and roadside parallel form, the parking space construction potential value is 70% of the current road length divided by 6.5, and then subtract the number of parking spaces; that is: r = current road length (m) * 70% / 6.5 - the current number of parking spaces in the parking lot, rounded down.

[0078] When the parking lot is single-side distribution and roadside vertical form, the parking space construction potential value is 70% of the current road length divided by 2.5, and then subtract the number of parking spaces; that is: r = current road length (m) * 70% / 2.5 - the current number of parking spaces in the parking lot, rounded down.

[0079] When the parking lot is double-side distribution and roadside parallel form, the parking space construction potential value is 70% of 2 times the current road length divided by 6.5, and then subtract the number of parking spaces; that is: r = current road length (m) * 2 * 70% / 6.5 - the current number of parking spaces in the parking lot, rounded down.

[0080] When the parking lot is double-side distribution and roadside vertical form, the parking space construction potential value is 70% of 2 times the current road length divided by 6.5, and then subtract the number of parking spaces; that is: r = current road length (m) * 2 * 70% / 6.5 - the current number of parking spaces in the parking lot, rounded down.

[0081] In practical application, the built roadside parking lot evaluation can be displayed on the system platform or large screen terminal through GIS map. The specific operation is as follows:

[0082] 1. The system accesses the built roadside parking lot information;

[0083] 2. Daily statistics of parking lot data, including the number of parking spaces, parking data, calculation period, utilization rate, etc.;

[0086] 5. The parking lot icon is represented by different colors. The color is based on the daily parking space utilization rate of the last month (last calculation period). Different parking space utilization rate value intervals are not displayed in the same color. For example, utilization rate ≥ 60% is displayed in red; utilization rate between 【30% - 60%) is displayed in yellow; utilization rate < 30% is displayed in green;

[0087] 6. The user can view the parking lot according to different dimensions of city, area, and street;

At the same time, the name, address, picture, total number of parking spaces, parking space form, parking space distribution, road length, charging rules, belonging merchant, average saturation trend chart of the parking lot at each time of each day of the parking lot are displayed;

[0089] 8. In the parking space distribution diagram, the parking spaces are distinguished by different colors, and the parking space icons show different colors according to the utilization rate of each parking space in the last month, such as red for utilization rate ≥ 60%; yellow for utilization rate between 30% and 60%; and green for utilization rate < 30%. When the mouse hovers over a certain parking space, the parking space number and daily parking time utilization rate of the parking space can be viewed;
