In this report, a brief history of the Valsalva (Valsalva-Weber) maneuver is outlined, followed by an explanation on the use of this approach for the evaluation of cardiac autonomic function based on underlying heart rate changes. The most important methodological and interpretative aspects of the Valsalva-Weber maneuver are critically updated, and some guidelines are established for simple app...

A key to the development of effective crash countermeasures is an understanding of pre-crash causal and contributing factors. This research effort was initiated to provide an unprecedented level of detail concerning driver performance, behavior, environment, driving context and other factors that were associated with critical incidents, near crashes and crashes for 100 drivers across a period o...

The decision making process in transportation is often about making a choice between alternative solutions to a problem. To select the best alternative, the decision should be based on results from a careful study of the implications of the alternatives. This paper presents the results of a study comparing two alternative interchange designsDiverging Diamond and Conventional Diamond Interchange...

95 THE CANADIAN HIGHWAY NETwork consists mainly of two-lane highways where passing slower cars requires traveling in the lane assigned to the opposite traffic. Therefore, studying the mechanism of the passing maneuver is important for maintaining traffic safety, as well enhancing the highway’s level of service. Models for passing maneuvers are available in the design guides1,2 while different v...

Distributed drive electric vehicles are regarded as a broadly promising transportation tool owing to their convenience and maneuverability. However, reasonable efficient allocation of torque demand four wheels is challenging task. In this paper, deep reinforcement learning-based distribution strategy proposed guarantee the active safety energy conservation. The task explicitly formulated Markov...
