Problems solved by technology

Parking lot selection and path guidance are the key core technologies in urban PGIS. However, there are still relatively few theoretical studies on parking guidance systems for parking lot selection that consider the individual needs of drivers at home and abroad.

Embodiment

[0047] (1) Before choosing the optimal berth, the main considerations of the parker when choosing a berth should be clarified first. Table 1 is the survey results of 200 volunteers on the factors that affect the choice of parking spaces. Integrating the existing research results, the present invention determines four main factors affecting berth selection: "traveling distance, walking distance, safety, difficulty of parking and storage" from the perspective of parkers.

[0050] (2) For the extracted fuzzy factors that affect the choice of parking spaces for parkers, establish corresponding membership functions or score them.

[0051] For the indicator "walking distance" (in meters), set several base words on the interval [0,80], respectively far γ 1 , relatively far γ 2 , nearly γ 3 ,Such as figure 2 As shown, its corresponding membership function:

Abstract

The invention relates to an evaluation method of parking space satisfaction based on interval type two fuzzy sets. For underground parking lots with parking guidance systems in large, medium and small cities, it can improve the parking efficiency of drivers and alleviate traffic jams. It is an effective way and method to solve the problem of "difficult parking" in cities. The method comprises the following steps: Step 1: According to individual needs, select factors that affect the selection of parking spaces; Step 2: According to the factors, use interval type II fuzzy set comprehensive evaluation to evaluate the satisfaction of the remaining berths in the parking lot, and obtain two Type fuzzy comprehensive evaluation matrix; Step 3: formulate fuzzy rules according to the evaluation matrix, obtain evaluation results and realize parking space selection. The features of the present invention are as follows: the present invention enables the parking space guidance system to achieve the goal of satisfying the berth selection in line with the preferences of the parkers, thereby allowing the parkers to induce satisfaction and trust.

Description

technical field [0001] The invention relates to the parking field of large-scale or underground multi-storey parking lots, in particular to the design and realization of a method for accurately inducing parking in large-scale or underground multi-storey parking lots. Background technique [0002] With the acceleration of world modernization and urbanization, the number of motor vehicles and traffic continues to increase, and the continuous improvement of the level of urban motorization has triggered a large number of parking needs. While cars bring convenience to people, existing parking facilities Under the imperfect situation, problems such as poor parking management, difficulty in parking, and difficulty in finding a car have also brought a lot of inconvenience to people's work and life. "Parking difficulty" has become one of the most difficult problems in urban traffic management, and is increasingly becoming a "bottleneck" that restricts the healthy development of urban...
