Embodiment Construction

[0067] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0068] In order to overcome the existing smart parking lot selection and route guidance methods, the number of user demand targets is small, the dynamic traffic environment that cannot adapt to real-time changes, the weight coefficient setting is complicated, the user preference information needs to be predicted, and the algorithm solution accuracy and stability are not high. Problem, the present invention designs a new intelligent high-dimensional multi-object...

Abstract

The invention provides a parking guidance method. The parking guidance method comprises the steps: acquiring the real-time road traffic data and the real-time parking lot data in an urban road network area, wherein the real-time road traffic data includes the road network data; according to the road network data, constructing a traffic network topological diagram; according to the destination and the real-time parking lot data, generating candidate parking lot sets; taking the user demand data as an objective function, according to a high dimension multi-target differential evolution algorithm, and selecting the optimal parking lot set from the candidate parking lot sets; and utilizing a single-target differential evolution algorithm to generate a parking guidance result according to the positional data of the user and the target parking lot which is selected from the optimal parking lot set by the user. The parking guidance method can realize static high dimension multi-target optimal parking lot selection and path guidance before a trip, can also provide dynamic real-time high dimension multi-target optimal parking lot selection and path guidance during the driving process, can fully consider dynamic changes of the parking lot and the road traffic information, and can effectively improve the accuracy and the intelligent degree for parking guidance.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a parking guidance method. Background technique [0002] Parking Guidance System (PGS) is one of the most important subsystems of Intelligent Transportation Systems (ITS). Management level, effective methods and approaches to solve the problem of "difficult parking" in the city. [0003] PGS generally consists of four subsystems: information collection, information transmission, information processing, and information release. Among them, the information processing subsystem is the most critical subsystem in PGS. The core technology includes intelligent parking lot selection and route guidance. However, at present, domestic research focuses on the overall architecture design of the PGS system and the layout of induced display screens. There are relatively few theoretical studies on intelligent parking lot selection and path-induced behavior decision-making, and the corr...
