摘要
交通量预测是城市道路可行性研究的核心内容,准确性和可靠性主要依据基础交通调查的准确度和覆盖率,而面对城市居民出行调查,问卷调查等传统的城市居民出行调查存在工程量浩大、耗时耗力、样本量低、经济投入巨大等诸多弊端。随着手机普及率的提高,手机覆盖了城市绝大多数人口,采用手机信令分析技术替代传统的出行调查成为可能。选择长沙市手机信令数据为基础,以长沙市人民路过湘江隧道的交通量预测为例,介绍了通过手机信令数据处理实现交通预测的解决方案。
Accuracy and reliability of traffic flow forecasting that is the core content of urban road feasibility study,are mainly based on the accuracy and coverage of basic traffic surveys.However,the residents trip survey,questionnaire survey and other traditional urban residents trip survey have many drawbacks,such as huge engineering,time-consuming and labor-consuming,low sample size,huge economic investment and so on.With the increasing popularity of mobile phones,analysis technology of mobile phone signaling is possible to replace the traditional residents trip survey.Based on the data of mobile phone signaling in Changsha,this paper takes the traffic flow forecast of Renmin Road Tunnel as an example to introduce the solution of traffic trip forecast through the data processing of mobile phone signaling.[Key words]mobile phone signaling;urban road;traffic trip forecast
