Abstract
To alleviate traffic congestion in urban area, it is very important to utilize the existing road space efficiently. This study proposed a countermeasure to alleviate traffic congestion at an arterial street in the center of Kochi City. The congestion is caused by an unbalanced lane usage due to right-turn vehicles and on-street parking vehicles, therefore reallocation of the road space and new road geometry are proposed. Analyses of efficiency and safety revealed that the proposal has enough capacity improvement to alleviate the congestion and no dangerous behavior is found in the driving simulator experiment.[This abstract is not included in the PDF]
