The article "modeling arterial signal optimization with enhanced cell transmission formulations" (z li. journal oftransportation engineering 2011: 445—454) presents a new method for timing traffic signals in heavily traveledintersections. the effectiveness of the new method was evaluated in a simulation study. in 50 simulations. the meanimprovement in traffic flow in a particular intersection was 654.1 vehicles per hour, with a standard deviation of 311.7vehicles per hour. a. find a 95% confidence interval for the improvement in traffic flow due to the new system. b. find a 98% confidence interval for the improvement in traffic flow due to the new system. c. a traffic engineer states that the mean improvement is between 581.6 and 726.6 vehicles per hour. with what level ofconfidence can this statement be made? d. approximately what sample size is needed so that a 95% confidence interval will specify the mean to within : 50vehicles per hour.)e. approximately what sample size is needed so that a 98% confidence interval will specify the mean to within : 50vehicles per hour.)
