Traffic chaos in weaving areas with the merging or diverging bay is a general problem encountered across the world. There are studies in the literature to find solutions to this problem and to develop calculation methods. When studies on weaving problems are examined in Turkey and World, no study has been found to evaluate vehicle movement types in the weaving areas by considering all vehicle types. Especially, a study is needed to examine vehicle movement types and suggest new geometries for the solution of the problem with such an evaluation. In this study, weaving confusion in three different weaving points in two metropolitan areas and the effect of many different parameters for the solution of weaving confusion were examined in detail with a diagnostic-based approach. In the study, total 7 different vehicle movement types were determined and it was tried to reveal how large the distribution of movement types caused by the confusion in the weaving areas. It was determined that the most common movement type was Type-1 with 39.2%, and the least common movement type was Type-6 with 3.1%. As a result, depending on the improvements in the traffic flow with the help of new geometry arrangements in three different weaving points, traffic safety will increase and complexity in the weaving areas will reduce on urban roads.
