Suppose you are a civil engineer, specializing in traffic volume control for the City of Grand Rapids. Your department has been receiving a multitude of complaints about traffic wait times for a certain intersection in the heart of downtown. To see if these claims are valid, you want to monitor the true average wait time at that intersection. Over the course of a few months, you record the average number of minutes a car waits at the intersection between 4:00 PM and 5:00 PM. With a sample size of 8 cars, the average wait time is 6.29 minutes with a standard deviation of 3.354 minutes. Construct a 90% confidence interval for the true average wait time for a car at the intersection between 4:00 PM and 5:00 PM.

A civil engineer aims to estimate the total number of potholes in a city so that a re-development budget can be drawn up. It is not possible to survey the whole city for practical reasons. Therefore, the city is split into a grid of 500 areas of size 1km2. The engineer randomly selects 50 of these areas and counts the number of potholes; a total 238 potholes are counted. Assuming that the potholes are geographically distributed according to a Poisson...

As an engineer you are responsible to in charge to conduct an experiment for this traffic flow analysis: At 2:00 P.M. a traffic accident closes a road to all traffic. At 2:15 P.M. the road is partially opened with a capacity (car departs) of 1,500 veh/h. Finally, the wreckage is removed, and the road is restored to full capacity (car departs) (3,500 veh/h) at 2:35. From 2:00 to 2:35, car arrives at a constant flow of 2,500 veh/h and then...

You are the city engineer of a large city. Name and describe any one system of systems (SOS) that falls under your control. List one concern that is likely to be associated with your SOS’s physical structure, operation, or physical condition. How would you assess the overall technical performance of (a) any one component system of the SOS and (b) the entire SOS? For the SOS, list and discuss any three costs or “disutilities” associated with the system.
