Despite the results obtained in literature to improve the macroscopic node model it is necessary to consider a general node model approach. A general node approach could take into account different aspects about conflicts at intersections. In this paper, the authors present a new node model based on cell transmission model (CTM) to represent traffic flows that cross signalized and unsignalized intersections. It allows to model complex intersections for urban contest. In particular, to represent different turn movements of the inflow at intersection and belonging at the same lane, the model introduces a new variable. It is utilized to represent the percentages of different turns. The model takes into account also the estimation of the merge flows at the intersection. The authors present a new model to compute the minor streams that are limited by major stream on unsignalized intersections. This model reduces the problems and the complexities of the capacity determination (based on gap acceptance) and it could be used for dynamic traffic assignment. The model could be used also for a complex signalized intersection, where many conflicts among through flows are presented. |
