1.) Spot Speed Study A student studying the spot speed of a rural road was able to measure spot speeds for 50 vehicles. If the standard deviation of the speed readings was ± 5.0 km/h and the limit of acceptable error was ± 1.5 mi/h. At 95% confidence level (Z = 1.96), a) Determine the required number of samples. b) Determine whether the student was able to satisfy the requirement for sample size.

The municipality that controls that arterial road reduced the posted speed limit, hoping to reduce the average speed of the road to 60 km/h. After introducing the new speed limit, the municipality collected a new speed sample (sample size = 220) to calculate the operating speed. The average speed and the standard deviation of the new sample were found to be 61.09 km/h and 8.95 km/h, respectively. Based on this information, answer the following question a) Is the speed reduction (if there is any) statistically significant? b) Was the target speed achieved by introducing the new speed limit?
A researcher was observing traffic along one lane of a rural highway. During a 1 minute time interval, ten vehicles were observed travelling 65, 64, 71, 66, 58, 72, 69, 66, 55 and 62 mph. Using these spot speeds, calculate the time mean speed (mph). Provide your answer to the nearest tenth of a mph.
The data shown below were obtained by time-lapse photography on a highway. Use regression analysis to fit these data to the Greenshields model and determine the following.

Q1. During a 60 seconds period, a loop detector is occupied by vehicles for the following times for the following, 0.34s (car1), 0.38s (car2), 0.40s (car3), 0.32s (car4) and 0.52s (car5). Estimate the value of flow, density and velocity. You can assume that length of the loop detector is equal to 10 feet and the average length of all vehicles is 20 feet.
