- Effectiveness Analysis for Transforming Many-Legs Type Intersection into Roundabout in Jeju
- Abstract
- oundabout is an intersection that allows vehicles to pass through the intersection by circulating the circular traffic island at the center of the intersection, and it is operated based on the main principle of the entering vehicle yielding to the vehicle already within the roundabout.
A modern style roundabout was introduced in the '90s in our country, and there are about 100 roundabouts in operation as of August 2009. In addition, roundabout design guideline (Ministry of Land, Transport and Maritime Affairs, 2010) suitable for the domestic condition is being established and supplied at the increasing need for introducing roundabout from the level of reducing accidents, enhancing traffic and revitalizing low-carbon green traffic. Furthermore, it is receiving much attention in recent as an eco-friendly road facility.
In this study, a comparative analysis was conducted on roundabout at five locations in order to deduce the operational result and financial effect of roundabout and signal intersection. As for the operational result, it was found that roundabout showed improvement effect in the average delay per vehicle compared to that of signal intersection by minimum of 65% and maximum of 91%. As for the average driving speed, roundabout showed operational improvement effect by minimum of 40% and maximum of 99%. Additionally, it was found that roundabout showed financial cost-saving effect in the traffic congestion cost compared to that of signal operation by minimum of 58.59% and maximum of 81% per year. It can be known from these analysis results that roundabout has significant operational effects under certain amount of traffic volume by allowing vehicles to pass through the intersection in a continuous way without much waiting time and stoppage from signal control.
Accordingly, it is necessary to actively review and supply the operational plan for roundabout that is effective in reducing energy consumption and air pollution emission from unnecessary signal waiting as well as reducing the traffic congestion cost, rather than indiscriminately operating signal intersection, in order to enhance smooth intersection traffic and improve safety by preventing and reducing traffic accidents.
