Driving Behavior and Traffic Flow

抄録

This Issue 4 of Volume 2 comprises seven papers focusing on the issues of driving behavior and traffic flow in Asia. The first two papers examine the issues of traffic accidents: one looks at the influence of individual attributes of drivers, especially those younger and older drivers (Park et al.), and the other investigates the influence of road surface conditions on driving behavior (Ranjitkar and Nakatsuji). The third and fourth papers investigate the issues of driving speed: the former emphasizing the effects of vehicle attributes (Saifizul et al.) and the latter analyzing the characteristics of free-flow speed (Tseng et al.), while the fifth paper (Narupiti et al.) estimates travel time based on driving speed. The sixth paper (Lin et al.) explores the ability to simulate traffic situation using the refined cellular automaton modeling in both pure and mixed traffic situations. The last paper (Tsukai et al.) explores the effects of different toll discounting policies on traffic flows, which are decomposed into independent components. Each of the components captures different temporal characteristics of traffic flows. Contents and findings of these studies as well as future challenges are summarized below.
