Enhanced Cell Transmission Model for Oversaturated Two Ways Arterials

The cell transmission model (CTM) is a potential simulation tool because it can accommodate all traffic conditions from light condition to oversaturated condition. This research aims to develop a traffic flow feature to improve the modeling of two-way arterials so that they are capable of modeling oversaturated conditions. Two improvements of the CTM are made to adequately study two-way arterials in oversaturated conditions. This enhanced model, proposed as the Conditional Cell Transmission Model (CCTM), is compared with Highway Capacity Software 2000 (HCS) in terms of travel speed. The consistency between the HCS 2000 and the CCTM show
