Problems solved by technology

However, this calculation method only uses the network data directly, ignoring the similarity and repetition of the urban bus network, thus affecting the accuracy of the final data
Therefore, even if the planned bus network density in a certain area meets the specification requirements, the actual network coverage may be uneven due to repeated network settings.
When the duplicate bus network is removed, the actual network density will decrease, and it may fail to meet the requirements of relevant regulations, thus failing to meet the travel needs of residents in some areas

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] attached figure 1 It is an overall flowchart of the present invention, as can be seen, the invention mainly comprises the following five steps:

[0028] Step 1: collect the basic GPS data of the bus lines, and the data includes the trajectories of the bus vehicles on each bus line, including longitude and latitude. The collected track data of the bus vehicles on the bus line is shown in the following table:

[0029] serial number longitude latitude 1 119.966646 31.791609 2 119.967568 31.79208 3 119.967703 31.792462 … … …

[0030] Step 2: Calculate the distance similarity according to the overlapping factors of the bus lines that affect the calculation of the bus line network density, and remove the repeated sections according to the degree of similarity. The de-duplication problem of bus lines...

Abstract

The invention provides a method used for calculating the bus network density of any region in a city. The invention relates to a bus system network density calculation method, and especially relates to the bus network density method in any region in the city based on multi bus line GPS data. According to the method used for calculating the bus network density of any region in the city, GPS data of a number of bus lines are split; a distance similarity technology is used to remove repetitive lines; non-repetitive lines are accumulated to acquire the total length of a road centerline; the total length is divided by a selected city area to seek the ultimate bus network density; and a good reference is provided for network planning and optimization of a bus company.

Description

technical field [0001] The invention relates to a method for calculating the line network density of a public transport system, in particular to a method for calculating the line network density of public transport in any area of ​​a city based on GPS data of multiple public transport lines. Background technique [0002] The bus network density refers to the length of the bus network in a unit area. It is usually expressed by the ratio of the length (L) of the bus network to the area (S), that is, the density of the bus network D=L / S. The density of public transport network can generally reflect the development level of a regional public transport network. Therefore, the density of public transport network is an important indicator to measure the service level of urban public transport. [0003] Urban public transport is a social public welfare undertaking that meets residents' basic travel needs, and is an important part of the transportation service industry. It is closel...
