Abstract
Weaving section is one of the major bottlenecks in urban expressway network and also known to hold high risk of accidents due to its complicated vehicles movements. The main cause of the above problems is the concentration of vehicles' lane change position and timing in a weaving section. This study assumed fully-controlled condition and proposed vehicle deconcentration control algorithm in a weaving section of urban expressway. The effects of this algorithm was examined using microscopic traffic simulator. As a result, this algorithm showed better performance than the current traffic situation, that is, it is expected to increase the capacity and to alleviate the congestion of the weaving section.
