- 2.The three main elements that define the geometry of a highway section are Horizontal Alignment, Vertical Alignment and Cross-sectional Alignment. Describe each element. 3.There are six distinct travel movements that may be present in a typical trip. Namely as the following: Describe each of the travel movement. a. Main movement b. Transition c. Distribution d. Collection e. Access f. TerminationA rural primary road segment of 2 miles long has an average annual daily traffic(AADT) of 11,350. The number of crashes that have occurred over the past 5 yearsare 5 fatal, 55 injury crashes and 100 property damage only crashes. Statewide averagecrashes for this type of road are 2 fatal, 130 injury, and 300 property damage onlycrashes per 100 MVMT. The weighting factors for fatal, injury and property crashesare 8, 3, 1, respectively. Using the critical crash ratio methodology, determine whetherthis site can be labeled a hazardous site. Use a 95 percent confidence limit.3 decimal places Potholes on a highway can be a serious problem, and are in constant need of repair. With a particular type of terrain and make of concrete, past experience suggests that there are, on the average, 3 potholes per mile after a certain amount of usage. It is assumed that the Poisson process applies to the random variable “number of potholes.” a.What is the probability that no more than two potholes will appear in a section of 1 mile? b.What is the probability that no more than 4 potholes will occur in a given section of 5 miles?

Traffic data collected at the same time indicated an average time headway of 3.7 sec. Part A. Determine the density on the highway in vehicles per mile. Part B. Determine the flow on the road in vehicles per hour. Part C. Determine the space mean speed in mph.The posted speed along Daang Maharlika Highway is 60 km/hr. The Table below shows the summary of 150 samples of spot speeds along Sumulong Highway. a. Compute for the Mean b. Compute for the Median c. Compute for Modal d. Compute for the 85th percentile (Using interpolation method) e. What is the speed limit for Daang Maharlika Highway?Q) Benefits of monitoring traffic please explain correctly with details
- A traffic engineer urgently needs to determine the AADT on a rural primary road that has the volume distribution characteristics as discussed. She collected the data shown below on a Friday during the month of March. Determine the AADT of the road. 1:00 –2:00 p.m. = 600; 2:00 –3:00 p.m. = 645; 3:00 –4:00 p.m. = 730; 4:00 –5:00 p.m. = 780; 5:00 –6:00 p.m. = 815; 6:00 - 7:00 p.m. = 795At a specified point on a highway, vehicles are known to arrive according to a Poissonprocess. Vehicles are counted in 30-second intervals, and vehicle counts are taken in 120 ofthese time intervals. It is noted that no cars arrive in 18 of these 120 intervals. a) Approximate the number of these 120 intervals in which exactly three cars arrive. b) Estimate the Percentage of time headways that will be 10 seconds or greater andthose that will be less than 6 seconds.What is the content of the Traffic Survey in the paper?
