摘要：A novel conditional cell transmission model (CCTM) is a potential simulation tool because it accommodates all traffic conditions from light condition to oversaturated *** test the performance of the CCTM,a series of experiments for sensitivity analysis were designed and performed for a multilane,two-way,three-signal sample *** 1 shows that the model is performed in a logical and expected manner with variations in traffic demand with time and *** 2 shows when the possibility of the occurrence of a useful gap increases to 60% and 100%,the delays in left turns decrease by 5% and 15%,*** Experiment 3,comparing the possibility of a conditional cell of 0 with 100%,delay of left turn and delay of the entire network were underestimated by 58% and 11%,***,sensitivity analysis demonstrates that by reflecting local drivers' behaviors properly,the CCTM provides an accurate representation of traffic flow in simulating oversaturated traffic conditions.
