Problems solved by technology

The optimal solution obtained in evolutionary calculations is often located near the boundary, and some infeasible solutions that are very close to the feasible area are eliminated because they cannot strictly satisfy the constraints, that is, the deterministic multi-objective optimization design may exclude the acceptable solutions in engineering practice. the optimal solution

Abstract

The invention provides a method for comprehensively evaluating intersection design schemes in a variable-weight manner on the basis of Monte-Carlo simulation. The method has the advantages that variable-weight factors and Monte-Carlo processes are combined with one another on the basis that evaluation indexes relevant to intersection designs are selected, and are applied to comprehensively evaluating and ranking the multiple plane intersection design schemes, uncertain factors are taken into consideration, and accordingly shortcomings of the traditional methods for evaluating multiple targets by the aid of constant-weight coefficients can be overcome; the method has practical value in the aspects of judging intersection operation conditions and analyzing cruxes of traffic systems.

Description

technical field [0001] The invention belongs to the field of road intersection design, in particular to a variable-weight comprehensive evaluation method for an intersection design scheme based on Monte Carlo simulation. Background technique [0002] Level intersections are key nodes in the road traffic system. Due to the characteristics of various traffic components, complex traffic behaviors, concentrated traffic conflicts, and unstable operating conditions at intersections, level intersections often become constraints that restrict the efficient, smooth, orderly, and safe operation of the traffic system. the bottleneck. Due to the rapid increase of traffic demand and the changeable and complex traffic operation environment, the influence of uncertain factors on the operation situation of intersections has become increasingly prominent. Analyzing the operational efficiency of intersections from the perspective of uncertainty has gradually become one of the hot spots that ...
