基于变量选择-神经网络模型的复杂路网短时交通流预测

摘要： 针对传统交通流预测模型正在由单断面历史数据处理向多断面、多时刻历史数据处理转变,但在考虑各断面间的影响时,多变的交通状况往往会使预测模型复杂化的问题,引入一种多元线性回归最小绝对收缩和选择算子方法(Lasso),并利用其优秀的变量选择能力,在复杂路网多断面中选出相关性较高的断面；结合神经网络(NN)的非线性特性,提出了Lasso NN组合模型.结果表明：Lasso NN模型在路网交叉口对未来15 min交通流数据预测的误差率低于9.2%；在非交叉口的误差率低于6.7%,总体优于各自单独使用得出的结果.

Claremont Colleges Emergency Preparedness: An Action Research Initiative

This study examines the role of knowledge management systems in the context of emergency preparedness at Claremont University Consortium. The research objectives required the researcher's direct involvement with CUC. Canonical action research methodology was used to guide the project. Overall, the client was satisfied with the project's outcome. The researcher designed and implemented an instantiation of a web-based knowledge management system using Wiki technology. This system can assist CUC in overcoming some of its immediate concerns with emergency preparedness. These include the ability of the system to facilitate the communication process, and enable a more structured approach for documenting and storing emergency related information. The system as it exists today is subject to further improvement. This includes the need for continuous training with the system, improving the navigational aspects, and seeking a better fit between the system and the emergency planning and response processes.
