Abstract
Since the queues caused by traffic congestion often occurred in the urban area, it became difficult for drivers to forecast the accurate travel time to the destination. Therefore, the importance of forecasting model for the expansion of spatially formed queueing length and reliable queueing length about the property of bottleneck phenomenon is highlighted. In this study, we used the CT (Cell Transmission) model which is one of the traffic flow models that analyzes the queue to analyze the maximum length of queue and the travel time of car in the unexpected incident and to examine the intrinsic error bound.As a result, in case of the expressway having tighter speed limit than urban arterial road, the q-k curve analyzing the traffic flow have smaller error bound. Consequently, in case of an expressway with higher speed limit than urban arterial road, analyzing the queue assuming that the q-k curve for the traffic flow analysis is trapezoidal shape has smaller error bound than the triangular q-k curve had smaller error bound. In the other way, triangular shape was suitable for urban arterial road.
