        PURPOSES : The lack of details of design guideline for zig-zag shaped section approaching central bus stop leads an traffic accident proneness. So, this study analysed the geometric elements of central bus stop area in terms of vehicle dynamics and suggested design alternatives. METHODS: The study analysed a dynamic behaviour of bus moving in and out of zig-zag shaped section using Auto-Turn under scenarios. Based upon dynamic analysis, the study found out the width of overtaking lane is the most influential factor for a safe moving at zig-zag alignment. RESULTS : The width of overtaking lane at design speed of 40, 50, and 60 km/h respectively was suggested given taper ratio of 1 to 10 required for Bus Rapid Transit (BRT), and the lane width is not wider than 4.0m which possibly makes two vehicles using the same lane. Also, the width of overtaking lane which mitigates the taper ratio was suggested with the same restriction about the maximum lane width. CONCLUSIONS: The results of the study can be used to prepare a design guideline on zig-zag shaped alignment of central bus exclusive lanes. The more stable moving is expected by applying the design alternatives suggested, therefore the lower rate of traffic crashes at the vicinity of central bus stops.

        This paper explores central Asia's contextualization mission strategy focused on national approach to culture of homogeneity and heterogeneity. This article attempts Central Asian society's common character and differences from the historic origin and each people's cultural diversity in Central Asia. Central Asia and the entire region contextualization of this article suggesting strategies to derive basically the most basic issues of the specification that can be raised. This article explores examining particularly Central Asia’s historical-cultural common homogeneity and individuality. Chapter II examines Central Asia's history-culture and mission : mission strategy of common homogeneity. Chapter III reviews Central Asia’s mission strategy after independence : factor elements of commonality and individuality. Chapter IV analyzes Contextualization mission strategy focused on national origin and mutual confrontation. As Uzbekistan and Tajikistan develop a stronger sense of their own independence, each country is establishing a new concept of view in explaining their national origin of its own history, which is then inserted into the state ideology. Moreover, because the historical paths of the two states overlap, they interpret the same historical events, from a nationalist perspective, in diametrically opposite ways. Contemporary Uzbekistan and Tajikistan are the territories with the strongest historical links in Central Asia. Since the acquisition of independence they have been marked by similar features of state and nation building.The aim of this article is to present a general overview of the contextualization mission strategy in Central Asia in examining common character and heterogeneous features of the Central people's surroundings after independence and the different aspects of a nation's most basic historical, traditional, understanding including national origin and political system. In exploring Central Asia's mission strategy. it need to be conducted study not only common aspects and heterogeneous nature in Central Asia to identify the distinctive aspects of the Central Asia mission strategy. This article's specification of mission strategy lies in the individual culture and ethnic-based access to a variety of strategies to be drawn to emphasize that what was done. Central Asia is a mission target area.

        PURPOSES : The purpose of this paper is to develop a methodology to estimate level of service of arterial including Exclusive Median Bus Lanes. METHODS : On 6 Exclusive Median Bus Lanes routes in Seoul, bus travel time and number of bus-stop per km were investigated. Also whether or not passing lane exists at bus-stop was checked. Based on the data from sites, bus travel time was estimated according to length of segment, number of bus-stop per km and whether or not passing lane exists at bus-stop. RESULTS : A bus travel time table was developed according to length of segment, number of bus-stop per km and whether or not passing lane exists at bus-stop. After bus travel speed and passenger car travel speed is estimated based on each travel time table and length of segment, two speeds are combined with weighted average speed using traffic volume of each lane group. Then weighted average speed is a measure of effectiveness of arterial including Exclusive Median Bus Lanes. CONCLUSIONS : It can be concluded that the proposed methodology can estimate level of service of arterial including Exclusive Median Bus Lanes considering the operation characteristics of Exclusive Median Bus Lanes.

        PURPOSES : In this study, the effects of when median exclusive bus lanes were applied to Daejeon trunk road (Wolpyeng crossway~Seodaejeon crossway, 6.3km) and (Daeduck Bridge 4~Kyeryong 4, 2.6km) by Microscopic Simulation VISSIM (5.0) was studied. The median exclusive bus lanes are one of the measures of transportation system manage techniques that can especially improve the efficiency of public transportation facilities. METHODS : According to the analysis of VISSIM on the Gyerong mainroad and Daedeok mainroad, when the median exclusive bus lanes were applied unlike when the roadside bus-only lanes were applied, the average travel speed of vehicles decreased but the average delay time and travel time increased. This arised from the changes in the geometric structure of the road which occurred the reduction of vehicle lane in the center of the road. RESULTS : In the case of bus, on the other hand, the average travel speed increased but the average delay time and travel time decreased. This is because the problems such as illegal parking and stopping, secondary road in out vehicle, and conflict of intersection right turn that roadside bus-only lanes occurred was solved. CONCLUSIONS : Although the introduction of median exclusive bus lanes will have a negative effect on general traffic flow due to the aggravation of travel, decrease of passenger car usage will lead to decrease of traffic volume. Therefore, smooth vehicle travel is expected.
