[0083] This embodiment provides a parking guidance method based on the most reliable path, figure 1 Shown is a schematic flow chart of the parking induction method. Such as figure 1 Shown, described parking induction method, comprises the steps:
[0084] Step S1, given the traveler's departure time and expected travel time;
[0085] Step S2, calculating the most reliable path from the starting point to each candidate parking lot according to the departure time and expected travel time;
[0086] Step S3, calculating the probability that each candidate parking lot has a free parking space at the expected arrival time;
[0087] Step S4, calculating the comprehensive reliability of the parking lot according to the probability of having vacant parking spaces;
[0088] Step S5, select the parking lot with the largest comprehensive reliability and the corresponding most reliable path, recommend it to the traveler, and guide the vehicle to the parking lot according to the correspo...

Abstract
The invention provides a parking guidance system and method based on the most reliable path. The system and method are used for solving the problem of low utilization efficiency of a parking lot in the prior art. The parking guidance method based on the most reliable path comprises the following steps of calculating the most reliable path from a starting point to each candidate parking lot according to the departure time and the expected travel time, and then calculating the probability of idle parking numbers of each candidate parking lot at the expected arrival time and the comprehensive reliability of the parking lot, thereby completing parking guidance. Through the system and method provided by the invention, the problems of searching the parking lot with the maximum comprehensive reliability and the most reliable path to the parking lot when the departure time and the expected travel time are given are solved. The phenomenon that the vehicle reaches the parking lot without the parking space can be effectively avoided by searching the parking lot with high reliability, the resource distribution of the parking lot can be optimized, and the utilization rate of the parking lot isimproved. The reliable path suggestion can be provided for the traveler by calculating the most reliable path, and the travel delay caused by travel time fluctuation is reduced.
Description
technical field [0001] The invention belongs to the field of urban traffic network and management, in particular to a parking guidance system and method based on the most reliable path. Background technique [0002] With the increasing number of cars in cities, "difficult parking" has become a difficult problem faced by major cities. Many people have encountered the dilemma of driving for 30 minutes and parking for half an hour. Parking guidance system is an effective tool to alleviate the "parking difficulty" problem, which can recommend available parking spaces for travelers. The parking guidance system integrates the data of scattered parking lots, transmits data through the network, releases parking information of each parking lot, provides parking space information for drivers, and guides drivers to choose suitable parking lots, thereby improving parking efficiency and reducing searching for parking spaces the amount of traffic brought. Prediction of vacant parking sp...
