Online traffic bearing capacity evaluation system

Abstract

The invention discloses an online traffic bearing capacity evaluation system. The invention relates to the technical field of traffic planning, urban planning and urban management. The system mainly comprises a cloud computing server composed of a cloud computing traffic model and a spatial database. The user side is composed of an evaluation parameter input module, a matched road planning module,a land planning module, a plot entrance and exit setting module and a traffic influence prediction display module; the spatial database stores basic electronic maps, electronic maps, background OD data, road network data, road condition data, mobile phone signaling data and enterprise internet LBS data of a plurality of regions. According to the method, big data, cloud computing and a traffic model can be organically combined, a user can complete all work from planning scheme input to online traffic bearing capacity evaluation only by following sequential operation of a client system, obviously, online traffic bearing capacity evaluation can be realized with high efficiency and high precision, and actual application requirements are met.

Description

technical field [0001] The invention relates to the technical fields of traffic planning, city planning and city management, in particular to an online traffic carrying capacity evaluation system. Background technique [0002] The evaluation of urban traffic carrying capacity is a complex system process. According to the characteristics of traffic carrying capacity, the evaluation process and the ambiguity of the evaluation results, the urban traffic carrying capacity is divided into the carrying capacity of traffic facilities and the carrying capacity of traffic environment, and an evaluation index system of traffic carrying capacity is constructed in combination with the current situation of urban traffic. [0003] The application of the multi-level fuzzy comprehensive evaluation mentioned in the prior art in the evaluation of urban traffic carrying capacity is to determine the objective weight of each evaluation index with the help of the entropy weight method, and combin...

Problems solved by technology

[0003] The application of the multi-level fuzzy comprehensive evaluation mentioned in the prior art in the evaluation of urban traffic carrying capacity is to determine the objective weight of each evaluation index with the help of the entropy weight method, and combine it with the subjective weighting method of the fuzzy consistent matrix. The multi-level fuzzy comprehensive evaluation method of combined weights. Although the evaluation results show that the combined evaluation method is more in line with the actual situation of urban traffic carrying capacity than the single evaluation method, it cannot realize the online traffic carrying capacity evaluation and does not meet the actual application requirements.
