I posted this question yesterday, but the solution feels wrong. In the solution, K and Kj were taken as the same value, is it correct? Apologies for resubmitting, there used to be a follow-back question option, but I can't see it.
Question 2 If the model In us= ln uf - k/kj is applicable to depict the correlation between speed (mi/h) and density (veh/mi) on a highway segment, and employing regression analysis provides the model constants Y = A + BX (where Y = In u, X = k) as A = 3.9 and B = -0.018, then calculate the: Jam density in veh/km. Express answer into two decimal places. Do not type the unit. veh/km.

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.
7. The following are the tabulation of the coverage count of the average daily traffic on a monthly and weekly basis made with automatic traffic counts on a highway. Use the tables to calculate;(a) the ADT for February and October based on 2 days counts: (i) on Tuesday in February the daily counts were 250 vehicles and (ii) on Friday in October, the daily traffic volume was 300 vehicles. (b) the AADT if the flows counted on Friday, Saturday and Sunday in July were 8000, 6000 and 5000 vehicles on a 16 hourly count basis.(c) the seven day 16 hourly flow in September.

At a specified point on a highway, vehicles are known to arrive according to a Poisson process. Vehicles are counted in 20-second s are intervals, and vehicle counts are taken in 120 of these time intervals. It is noted that no cars arrive in 18 of these 120 intervals. Approximate the number of these 120 intervals in which exactly three cars arrive.
