Embodiment Construction

[0052] The present invention is described in detail below in conjunction with accompanying drawing:

[0053] The present invention explains as follows to the related concept in the taxi cruising behavior analysis method based on GPS data grid statistics:

[0054] 1. Definition of cruise point

[0055] Refers to the driving trajectory point when the taxi is empty and looking for passengers.

[0056] 2. Definition of passenger loading point

[0057] Refers to the trajectory point when the taxi receives passengers, that is, the trajectory point when its driving state changes from empty to full.

[0058] 3. Historical passenger loading point information

[0059] Refer to the location information of the taxi driver who has received passengers before, which is represented by the distribution of passenger points on the previous day in the present invention.

[0060] 4. Spatial autocorrelation of cruise points

[0061] It refers to the spatial correlation existing between the obs...

Abstract

The invention discloses a taxi cruising action analytical method based on global position system (GPS) data grid statistic in the field of traffic action research. Spatial distribution characteristics of cruising points are analyzed based on taxi traveling track GPS data identification cruising points to generate passenger carrying points and background information points representing factors such as land, population and road networks of the previous day, grid analysis technique is adopted to convert spatial point data into point frequency data based on grids, a zero-inflated negative binomial model (ZINB) is constructed to analyze historical passenger carrying point information, background information and influences of spatial autocorrelation of the cruising points on taxi cruising point choice action, and cruising strategies of a taxi are summarized. The taxi cruising action analytical method brings convenience to further taxi traffic behavior simulation and provides an effective way for optimizing taxi cruising action and solving problems of road resource waste, fuel consumption and environmental pollution caused by cruising.

Description

technical field [0001] The invention relates to a taxi travel behavior analysis method in the field of traffic behavior research, in particular to a taxi cruising behavior analysis method based on GPS data grid statistics. Background technique [0002] Taxi is an important means of urban transportation, and the analysis of taxi cruising behavior is an important topic in the field of traffic behavior research. Cruising behavior refers to the operating behavior of taxis when they are looking for passengers when they are empty. At present, taxis in large and medium-sized cities in my country have generally installed vehicle-mounted GPS equipment, which provides convenience for the collection of cruise data. With the help of grid technology and spatial point modeling and analysis methods to process and analyze taxi GPS cruise data, and summarize taxi cruise behavior characteristics, it can optimize taxi cruise routes, improve cruise efficiency, and solve the waste of road resou...
