The ARENA simulation model gives the transfer times for each lane. The average travel time for all the entities entering the driving lane is calculated as 39.59 seconds, and the average travel time for all the entities entering the passing lane is calculated as 35.26 seconds. Dividing total length simulated which was 3000 feet by these average transfer times gave the overall average speeds for each lane. Average Speed on Driving Lane = 3000 ft / 39.59 sec = 75.77 ft/sec Average Speed on Passing Lane = 3000 ft / 35.26 sec = 85.08 ft/sec 105 In the model, the speeds were assigned according to a normal distribution using the averages and standard deviations given in Table 15. The speeds assigned for the transporters on the driving lane were 88 feet/sec for 700 ft distance and 75 ft/sec for 2300 ft distance. The speeds assigned for the transporters o...
