Urban bus index calculation method based on RGB color space and Monte Carlo method

Abstract

The invention discloses an urban bus index calculation method based on an RGB color space and a Monte Carlo method. The method specifically comprises the following steps: acquiring a land utilization overall planning map of an urban to-be-researched area and land area data of a researched area; acquiring position information of public transport stations in a specified research area of the city; digitizing the overall planning graph into an RGB matrix; under the same coordinate system, matching the geographical location information of the land utilization overall planning map with the obtained location information of the regional public transport stations; determining RGB vectors of a blank area and a non-urban land area of the overall planning map; based on a Monte Carlo method, calculating the total land use area and the total bus coverage area of the to-be-researched region; and calculating the bus coverage rate and the bus station density. The method provided by the invention has great significance in calculating the improved urban public transport related indexes, establishing a scientific and systematic urban public transport evaluation index system and further measuring the urban public transport development.

Description

technical field [0001] The invention relates to an urban public transport index calculation method based on an RGB color space and a Monte Carlo method, and belongs to the field of urban public transport planning and evaluation. Background technique [0002] As my country's transportation has entered a new stage of development, transportation has become more and more intensive and green. At the same time, environmental protection concepts such as "carbon neutrality" have risen to the level of the national outline, which means that my country's urban development will further strengthen environmental protection in the future. attention. Transportation is one of the important sources of carbon emissions. Promoting the development of public transportation can not only reduce urban traffic congestion, improve the travel efficiency of residents, but also greatly reduce the large amount of vehicle exhaust emitted by private cars, which is in line with the sustainable development of ...

Problems solved by technology

The goal of the public transport index is to reflect the service of public transport to people, so the above-mentioned areas should be excluded in the actual calculation, but this will obviously make the calculation process more complicated, so a method that can refine the research area and simplify the calculation complexity is proposed. It is necessary to calculate the relevant indicators of urban public transport
