Assume you are an observer standing at a point on a three lane race track. All vehicles in lane 1 are traveling at 50 mi/h, all vehicles in lane 2 are traveling at 65 mi/h, and all vehicles in lane 3 are traveling at 70 mi/h. There is a constant spacing of 0.25 mile. If you collect spot speed data for all vehicles that pass your observation point in one hour, what will the time-mean speed be for the traffic stream?
Consider only a single lane of a highway. Based on extensive data from an urban freeway it is assumed thatfree-flow speeds (i.e., there are no jams) can best be represented by a Normal distribution with mean andstandard deviation 119 km/h and 13.1 km/h, respectively.1. What is the probability that the speed of a randomly selected vehicle is between 100 and 120 km/h?2. What is the expected number of vehicles between two vehicles that exceed the posted speed limit of100 Km/h? You can use the Z table for calculating the final answer. You can also write your final answer in form ofR functions or as PDF/CDF of statistical distributions with correct arguments.
A data collection study found a linear speed - density relationship for a highway as follows u/65 +k/120 =1 1-Write down the speed - density ( given ) , flow - density and flow - speed models , and plot their relationships 2-raffic study has shown that the time headways between successive vehicles on this highway are exponentially distributed and that 30% of the headways between vehicles are 4 seconds or greater. Apply the traffic models derived in the question a), compute speeds and densities corresponding to this flow.
Two sets of students are collecting traffic data at two sections, xx and yy, of a highway 1,200 ft apart. Observations at xx show that five vehicles passed that section at intervals of 3, 4, 3, and 5 sec, respectively. If the speeds of the vehicles were 55, 50, 45, 40, and 35 mi/h, respectively, determine the space mean speed (in km/h) for the data using the following equation where ut and us are in km/h. (Round your answer to at least three significant figures.) ut = 0.966us + (3.541 km/h) km/h Determine the space mean speed (in km/h) for the data using the following equation. (Round your answer to at least three significant figures.) us = n n 1 ui i=1 km/h Compare your answers and discuss the results.

Speed data collected on an urban roadway yielded a standard deviation in speeds of 4.8 mi/h. (a) If an engineer wishes to estimate the average speed on the roadway at a 95% confidence level so that the estimate is within 2 mi/h of the true average, how many spot speeds should be collected? (b) If the estimate of the average must be within 1 mi/h, what should the sample size be?
