A study on setting-up a methodology and criterion of exclusive bus lane in urban area

To case traffic congestion in urban area exclusive bus lane has been operated by means of transportation demand management strategy. However, because criterion of busonly lane is not defined clearly, this strategy has been used indiscreetly. The purpose of this study is setting-up a methodology and criterion of exclusive bus lane using the point that makes the travel times between bus and automobile equal after operating it. This point is regarded as traveler equilibrium. If we find these criteria and use those effectively, we anticipate improving availability of bus and decreasing traffic congestion ultimately by deploying the exclusive bus lane. To perform this study, we use the traffic simulation package, NETSIM, and review real two areas such as Kangnamdaero, or the Kangnam Road in southern Seoul and Sejongro/Taepyongro in northern Seoul. As a result, it is analyzed that the exclusive bus lane is useful only above particular points that correspond to specific total traffic volume and bus volume. But this study has some limitations that bus lane is operated only on median lane and the number of sample area is small. So this aspect needs to be considered later.
