Abstract

The invention discloses a traffic carrying floor area ratio calculation method based on a mathematical model. The method comprises the following steps: acquiring a preset urban building model, calculating traffic carrying capacities of neighborhoods and traffic production of the neighborhoods according to the mathematical model, and adjusting adjustment coefficients of the neighborhoods by judging a magnitude relationship between the traffic carrying capacities of the neighborhoods and the traffic production of the neighborhoods; adjusting adjustment coefficients of units by judging a magnitude relationship among traffic production of traffic carrying capacity units of units according to a traffic carrying capacity of a mathematical model calculation unit and traffic production of the units; and calculating a traffic carrying floor area ratio of a land parcel according to the adjustment coefficients of the neighborhoods and the adjustment coefficients of the units. The invention also discloses a traffic carrying floor area ratio calculation system based on the mathematical model. Through adoption of the traffic carrying floor area ratio calculation method and system, a calculation process of a traffic carrying floor area ratio is simplified, and the cost is lowered.

Description

technical field [0001] The present application relates to the field of road traffic, in particular to a mathematical model-based calculation method and system for traffic carrying volume ratio. Background technique [0002] FAR is an important tool to regulate the development factors of urban land economy, resources, society, environment, etc., and has attracted the attention of the government, developers, urban residents, and other social parties. The relationship between land development volume ratio and urban road traffic is very close: if the volume ratio is too high, it will easily cause road traffic congestion, and the road traffic carrying capacity needs to be increased accordingly; . [0003] However, in the current urban planning, due to the lack of scientific quantitative calculation methods for the formulation of the floor area ratio, there is insufficient research on the feasibility of the road traffic carrying capacity of the floor area ratio. Especially for t...
