Meanwhile, in case of correlation among observations in the same segment, a multilevel modeling structure has been implemented. Furthermore, a data mining technique--Support Vector Machine (SVM)--is used to distinguish crash from non-crash observations. Once the crash mechanisms for special expressway facilities are found, we are able to provide valuable information on how to manage roadway facilities to improve the traffic safety of special facilities. This study adopts Active Traffic Management (ATM) strategies, including Ramp Metering (RM) and Variable Speed Limit (VSL), in order to enhance the safety of a congested weaving segment. RM regulates the entering vehicle volume by adjusts metering rate, and VSL is able to provide smoother mainline traffic by changing the mainline speed limits. The ATM strategies are carried out in microscopic simulation VISSIM through the Component Object Model (COM) interface. The results shows that the crash risk and conflict count of the studies weaving segment have been significantly reduced because of ATM. Furthermore, the mechanisms of traffic conflicts, a surrogate safety measurement, are explored for weaving segments using microscopic simulation. The weaving segment conflict prediction model is compared with its crash prediction model. The results show that there are similarity and differences between conflict and crash mechanisms. Finally, potential relevant applications beyond the scope of this research but worth investigation in the future are also discussed in this dissertation.

Speeding is the number one road safety problem in a large number of OECD/ECMT countries. It is responsible for around one third of the current, unacceptably high levels of road fatalities. Speeding has an impact not only on accidents but also on the ...

Design innovation for electrically powered and hybrid-electric aircraft is accelerating rapidly. While there are many potential benefits of electric aircraft and hydrogen technologies, not all air service can be replaced by electrically powered aircraft in the near term. The TRB Airport Cooperative Research Program's ACRP Research Report 236: Preparing Your Airport for Electric Aircraft and Hydrogen Technologies offers an introduction to the emerging electric aircraft industry, gives estimates of potential market growth, and provides guidance to help airports estimate the potential impacts of electric aircraft on their facilities and to be prepared to accommodate them. A series of appendices provides details on the assumptions and methods used in the research as well as helpful references for airport planning. A toolkit includes a database of more than 100 electric aircraft and may be used by airports to estimate future electric power requirements at their airport based on local characteristics (such as climate, aviation activity levels, existing electrical demand).
