数据赋能下的道路交通信号控制

Data Empowerment-Oriented Road Traffic Signal Control

信号控制已具备高联网化、控制多元化、能力服务化的特征,但面对道路感知设施建设,还未形成对数据的体系化应用能力.本文围绕信号控制进行数据应用的探讨,提出大数据环境下的数据需求,同时为微观、中观、宏观三个层面的数据分析提供基本分析思路;结合信号控制业务阐述数据分析对控制策略与控制模式的影响与关联,作为多目标和多场景下道路交通信号控制优化的参考.

Signal control has the characteristics of high networking,diversified control and service-oriented capabilities,but in the construction of road sensing facilities,the systematic application ability of data has not yet been formed.This paper discusses the application of data in signal control,puts forward the data requirements in the big data environment,and provides basic analysis ideas for data analysis at the micro,meso and macro levels;combines with the signal control business to explain the influence and correlation of data analysis on control strategy and control mode,which serves as the reference for road traffic signal control optimization in multi-target and multi-scenario.
