Abstract

The invention discloses an event-driven real-time prediction method and system for the number of vacant parking spaces. The method includes obtaining historical parking information and performing continuous repair and smoothing processing on it; the historical parking information includes historical vehicle arrivals. Time, departure time, driving event occurrence time and the number of historical parking spaces available; based on the driving event occurrence time, historical parking information and assuming that the parking arrival probability obeys a normal distribution, the arrival of parked vehicles between the current moment and the next moment is obtained probability and departure probability; and then based on the difference between the actual number of available parking spaces collected at the current moment and the sum of the arrival probability and departure probability of parking between the current time point and the next time point, a prediction model for the number of available parking spaces is obtained; Both the time point and the next time point are input into the prediction model of the number of available parking spaces, and the prediction value of the number of available parking spaces is output in real time.

Description

technical field [0001] The invention belongs to the field of traffic information systems, and in particular relates to an event-driven real-time prediction method and system for the number of vacant parking spaces. Background technique [0002] With the proliferation of vehicles in China's cities, the imbalance between parking demand and supply has caused a variety of traffic problems. The uneven distribution of parking demand and supply during peak hours prevents the efficient use of parking spaces and increases the traffic pressure on urban roads. The Parking Guidance Information System (Parking Guidance Information System) collects parking space information, estimates and predicts the number and location of vacant parking spaces, provides real-time and accurate information to users, assists users in planning travel routes, and facilitates parking lot managers to effectively manage vacant spaces. [0003] Domestic and foreign research on the prediction of vacant parking s...
