DEVELOPMENT OF AN ALGORITHM TO AVOID VEHICLE CONFLICTS UNDER MIXED CONDITION OF AUTOMATED AND MANUAL DRIVING IN WEAVING SECTIONS

Abstract

Weaving section is one of the bottlenecks in expressway network and because of the higher construction cost and longer construction period, it is difficult to add new lanes. However, if automated driving is introduced by ITS technology, it has possibilities to improve traffic capacity without any additional construction. The previous studies showed that traffic capacity could be improved by automated driving, but assumed all vehicles are automated. On the other hand, this study assumed mixed condition of automated and manual driving, and proposed a vehicle control algorithm in a weaving section of expressway.
As a result of simulation run, mixed condition showed improvement over only manual driving although the improvement is less than that of all automated condition.
