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

抄録

A two-lane road, as a road having very great weight, occupies 51.4% of the general national roads and 72.6% of the local roads[state-supported local roads included] and it is operated in the way of letting only one-lane available by direction. 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. However, 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. Particularly, traffic delays are ever aggravating due to the traffic characteristic of the high mixing rate of truck traffic.
