Research on effective evaluation and design guidelines for low-speed traffic flow yield-type in two-lane highway

抄録

A two-lane road, when a traffic jam arises due to a front-running vehicle, there is a characteristic of having to overtake it by using the lane for the opposite direction. Most of our topography is mountainous and what is worse, the length of overtaking section is limited to 200m ∼400m. Thus, there exist a lot of limits to high-speed vehicles' overtaking. Thus, the installation of a low-speed traffic flow yield-type lane is positively encouraged aiming for the effective management of a two-lane road and reduction in accidents arising from reckless overtaking using an opposite direction. For this purpose, this research selected a yield lane the most suitable for our country's topography & traffic characteristics as an analytical alternative by conducting an examination of the pattern of a low-speed traffic flow yield-type lane, such as yield lane and turnout, etc. In addition, this research elicited the most suitable length & installation interval of a yield lane through PTSF analysis subsequent to the mixing rate of truck traffic and traffic volume.
