The analysis of travel and emission impacts of travel demand management strategies using activity-based models

This paper demonstrates, tests and shows the value of activity-based travel demand models and household sample enumeration forecasting techniques in evaluating the transportation and air quality impacts of travel demand management strategies. Using data from the Portland, Oregon metropolitan area, three transportation policies were evaluated both individually and in combination: transit improvements, pricing, and telecommunications. The activity-based models used in this testing represents a significant improvement to today's "four-step" sequential model systems by providing a deeper insight into the individual decision making process in response to transportation policies. A wider range of impacts is predicted, and indirect effects as well as synergistic effects of such policies are taken into consideration. These models are capable of providing the information needed to improve the linkage of transportation models with emissions and air quality analysis methodologies by improving the prediction of variables that are important to accurately estimating emissions and air quality impacts of transportation actions.     

秦岭隧道排出水化学异常对地表水质影响评价

为评价隧道施工和排出水对地表水体水质的影响,对两条河流的水质进行了监测。现以饮用水水质都分因子为标准,将地表水水质划分为3个级别,并采用模糊综合评判法和灰色模型法对3个监测断面的地表水水质进行了综合评价,结果表明,两条河流水质良好,基本未受隧道施工及排出水的影响。     

FINE-GRAINED DISTRIBUTED MULTIMEDIA SYNCHRONIZA-TION MODEL——ENHANCED FUZZY-TIMING PETRI NET

IntroductionDistributed multimedia systems integrate a va-riety of media,including time dependent media,such as audio and video,and time independent me-dia,such as text,graphics,and images.Multime-dia synchronization refers to the temporal composi-tion of the data streams. Strams can be composedof temporal series of information units called Logi-cal Data Units (LDU) (e.g.,a video stream is atemporal series of video frames) .Multimedia synchronization can be modeledaccording to different gra…
