Abstract

The invention discloses a road plane line type continuous balance evaluation method and device based on equal-length section division. According to the method, a plane line type is divided into multiple unit sections based on an equal-length section division method according to plane line type design schemes; on the basis of calculating an adjacent unit bow ratio balance coefficient, an adjacent unit element quantity balance coefficient and an adjacent unit turning characteristic balance coefficient, a variable coefficient method is adopted to calculate a plane line type continuous balance comprehensive coefficient; and the comprehensive score of each scheme is calculated, and a comprehensive ranking of the plane line type schemes is obtained to quantitatively evaluate continuous balance of the plane line type schemes. The device designed according to the method comprises nine parts, namely a data import module, a parameter setting and unit section division module, a unit section element extraction module, a unit section element integration information processing module, a continuous balance basic indicator calculation module, a continuous balance comprehensive coefficient calculation module, a comprehensive ranking module, a data storage module and a data output module. Through the road plane line type continuous balance evaluation method and device, continuous balance evaluation of different plane line type schemes can be implemented, and the convenience and precision of plane line type continuous balance calculation are improved.

Description

technical field [0001] The invention relates to a method and device for evaluating the continuity and balance of road plane alignment based on equal-length section division, and belongs to the technical field of road design. Background technique [0002] Road linear geometry is an important factor affecting road safety. In the process of road design, it is necessary to combine road construction and planning conditions to optimize the design of road alignment to improve the safety of road design. At present, the evaluation methods of road alignment design mainly include ten categories, namely: traffic safety evaluation based on the correlation between traffic accidents and alignment indicators, evaluation based on alignment index, evaluation based on running speed, evaluation based on acceleration, and fuel consumption-based evaluation. Evaluation, evaluation based on vehicle stability method, evaluation using three-dimensional scene model and perspective method, method base...
