Observations at xx show that five vehicles passed that section at intervals of 3, 4, 3, and 5 seconds, respectively. If the speeds of the vehicles were found through radar gun measurements to be 50, 45, 40, 35, and 30 mph respectively, a.

The results of a speed study are given in the form of a frequency distribution table. Find the time mean speed and space mean speed. speed rang: (2-5),(6-9),(10-13),(14-17)frequency: 1,4,0,7
This is a three-part problem. Two sets of students are collecting traffic data at two roadway stations, station 130 + 00 and station 145 +00. Observations at station 130 + 00 show that five vehicles passed that section at intervals of 0, 3, 4, 3, and 5 sec, respectively. If the speeds of the vehicles were 50, 45, 40, 45, and 50 mph respectively. Note: Stationing is fundamental to highway plans. A station is the horizontal measurement along the Construction Survey Line of a project. Distances are measured and points are identified on plans with reference to station numbers. One hundred feet is equivalent to one station. Highway stationing might be compared with a rope having knots at 100-foot intervals. The beginning end of the rope would be 0, the first knot at 100 feet would be Station Number 1 and would be written as 1+00. The second station number would be 2 (which is 200 feet from the beginning) and would be written as 2+00, and so on. Part A. Determine the time mean speed, in mph.…

Determine the density on the highway e. Determine the flow Recalculate the space mean speed from Problem 1, using the empirical equation developed by Garber & Sankar: ūt = 0.966ūs + 3.541. Compare this answer to that calculated in Problem 1.
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.
road construction The 20-year projection of annual average daily traffic of a two-way roadway is 36.500 vehicles. Theroad serves as a highway between a residential area and a business area and the expected directionaldistribution factor is D=0.6. The 30th peak hour factor for the roadway is K=0.15. During an hourly vehiclecount, the following values were registered: 1st 15 minutes: 200 cars, 2nd 15 minutes: 130 cars, 3rd 15minute 230 cars, 4th 15 minutes. 180 cars. Estimate the peak hour factor . What is the designdirectional hourly volume for this route?
. A traffic enforcer counts the number of vehicles at a specific location in the highway. In hiscounting, there are 420 vehicles arrived in span of 1 hour. Assuming that the arrival of vehicles isPoisson distributed, estimate the probabilities of having 7 or more vehicles arriving over a 30-secondtime interval
What are the different types of information which you can derive from distance time graph of severalvehicles on a traffic stream? Explain with examples
