Instrumented city database analysts using multi-agents

The Instrumented City (iC) database is a multi-purpose, transport-related database facility for use by the entire academic transport research community. Data from the UK Leicester City Council and Nottinghamshire County Council Traffic Management Computers is logged and archived on a continuous basis, by the Leeds University’s Institute for Transport Studies. Since its inception in 1992, the iC database has been used for various real-time applications such as air quality and noise monitoring, modelling and forecasting. This paper describes the framework that demonstrates the feasibility of using multi-agents as information analysts to process and manage the iC database. The agents are adaptive, interactive and personal. They can be trained via the interactions with the users to be personalised for individual preferences. These agents are designed to be responsible for (1) data clean-up to remove outliers; (2) missing data substitutions; (3) statistical data analysis; (4) data mining to enhance the understanding of the relationships between traffic and air quality, noise and health; and (5) knowledge discovery by identifying unknown but potentially important patterns.     

交通信号区域协调优化的多智能体博弈模型

本文以多智能体技术和博弈论为基础,对交通信号的区域协调模型进行了研究。文章首先对多智能体交通控制系统做了简单的介绍,然后应用博弈论的相关知识建立了Agent之间的协调模型并给出协调算法,在此基础上对一个简单的交通网络进行仿真,仿真结果表明本文所建立的区域协调模型的有效性。
