A Cell-Based Intersection Flow Transition Model for Dynamic Traffic Loading in Two-Way Urban Road Networks

This paper puts forward a convenient model called the cell-based intersection flow transition model (CIFTM), to extend the traditional cell transmission model (CTM) to deal with intersection situations on two-way road networks. Taking the VISSIM software as the reference standard, the performance of the proposed CIFTM is compared with the widely used general node model. The results of the comparison show that the CIFTM can model more realistic traffic flows occurring at intersections than the general node model. Also, the CIFTM’s simulation results are identical to those of VISSIM, and demonstrate CIFTM’s potential to assist with other traffic engineering research topics such as dynamic traffic assignment.
