Large-scale parking lot entrance and exit congestion studying and judging method based on vehicle average delay

Abstract

The invention provides a large-scale parking lot entrance and exit congestion studying and judging method based on vehicle average delay, and the method comprises the following steps: selecting a research target large-scale parking lot, carrying out the field investigation, and obtaining the historical traffic volume and actual vehicle delay information of various types of vehicles under different paths; selecting a corresponding vehicle average delay model according to the vehicle type, and carrying out parameter calibration; predicting the future total traffic volume of each road, and analyzing the traffic volume composition mode under different paths; calculating an average delay range of each type of vehicles, and comparing the average delay range with an average delay threshold value of the vehicles when congestion occurs; and judging whether a congestion time period exists or not, and determining an adjustment strategy. The system provided by the invention analyzes the operation characteristics and interaction influence of the multi-type traffic volume of the entrance and exit of the large-scale parking lot, quantitatively analyzes the congestion cause and congestion degree of each type of vehicles based on the accurate calculation of the average delay of the vehicles, and is a new means for studying and judging the congestion of the entrance and exit under the background of continuously increasing urban large-scale parking lots.

Description

technical field [0001] The invention relates to a method for researching and judging congestion at entrances and exits of large parking lots based on average vehicle delay, and belongs to the field of urban road traffic control. Background technique [0002] With the rapid increase of the number of motor vehicles in my country and the situation of domestic land intensification, a large number of large parking lots have emerged. The increase in the number of parking spaces in the parking lot can solve the problem of insufficient parking spaces, but it aggravates the impact of dynamic and static traffic, thus deriving a series of new "parking difficulties" problems. Among them is the bottleneck problem of entrances and exits and connecting roads, which is not only directly related to the difficulty of motor vehicles entering and exiting the parking lot, but also causes slow or congested driving on connecting roads and surrounding road networks, reducing road traffic efficiency...
