Computation of cell transmission model for congestion and recovery traffic flow

Cell transmission model (CTM) is one of the most comprehensive, updatable and easy-to-implement models among the existing macroscopic traffic models that approximates the road conditions for immediate information uphold. For instance, it is believed that minimal interpretation from traffic modeling in crowd-sourced route navigation apps will support for user input information checking and verification based on the road conditions. This paper demonstrates the computation of discrete based hydrodynamic CTM in road disturbance and flow recovery to explain the credits and drawbacks of CTM through the model establishment in simulations. Different sample time attempted in the studies suggested a tradeoff between level of details and computational effort are also discussed in this paper.
