A two-lane two-way traffic light controlled X-intersection for ternary mix traffic (cars + buses (equivalent vehicles) +
very large trucks/ buses) is developed based on cellular automata model. This model can provide different matrices such
as throughput, queue length and delay time. This paper will describe how the model works and how composition of
traffic mix effects the throughput (numbers of vehicles navigate through the intersection per unit of time (vph)) and also
compare the result with homogeneous counterpart.
