Driving lane and passing lane had different inter-arrival time distributions at different time intervals. The results for the simulation of the construction work zone traffic were obtained for both lanes separately, which helped us to determine the difference between the output parameters for these two lanes. The analysis of the results of ARENA simulation model showed that the re was no actual queue formation at the construction zone simulated. There was at the most a very slight increase in the 116 average travel times through the construction zone according to the number of vehicles per hour increases both for driving lane and passing lane. The results of the QuickZone delay estimation program also showed that there were no queues formed and delays observed at the construction work zone simulated. The results of both simulation models provided similar outputs, showing that there were no queues and delays observed at the I-76 Westbound Construction zone. 4.3 Discussion of Results The data collected in the construction work zone was used for the modeling of the simulation programs in this study. The use of the actual data provided more realistic results for the simulation outputs, both for developed ARENA model and QuickZone model. In the ARENA simulation model, probabilistic inter-arrival time distributions were used for different time intervals and th...
