交通诱导信息对可变信息标志选址影响分析

摘要

Variable message signs is an important part of traffic guidance system and it plays an important role at the macro level of urban traffic management. Induced traffic information has very big effect on the location of VMS in scientific and accuracy.Establish the location choice model and the improved model based on the analysis information needs and the location factors of VMS. Lastly, determine the influence regular of VMS location Combined with an example.%可变信息标志是交通诱导系统的重要组成部分,在宏观上对城市交通管理起到重要作用.交通诱导信息对可变信息标志选址的科学性和准确性有很大影响.本文根据交通诱导信息对VMS信息需求及布点影响的分析,建立VMS数学规划选址模型及其改进模型,结合算例分析计算确定其对VMS选址的影响规律.
