Q.47 An observer counts 240 veh/h at a specific highway location. Assume that the vehicle arrival at the location is Poisson distributed, the probability of having one vehicle arriving over a 30- second time interval is
The following data were taken on five vehicles travelling consecutively 1.5 km portion of the NLEX. Vehicle Time (minute) 1 1.2 1.0 3 1.4 4 1.3 1.1 Determine the time mean speed (kph) 76.07 75.00 O 76.00 O 75.07 2.
Two observers have determined that the time headways between successive vehicles are exponentially distributed and that 70% of the headways are 8s or greater. If one of observer decides to count traffic in 40s intervals, and the other in 35s intervals, estimate the probability of each observer counting 5 or more vehicles in their own intervals?

1) The number of accidents has been recorded at an intersection in the last three years as follows: 18, 21, and 19. The accidents were mostly due to left-turning vehicles, speeding, and the absence of left-turn protection. The average ADT for the last 3 years is 8500. The following shows the crash reduction factor for various countermeasures: Countermeasure Reduction Factor Retime signals Provide left-turn signal phase Reduce speed limit on approaches Provide turning guide lines 0.30 0.30 0.35 0.05 a) Determine the appropriate countermeasures b) Determine the expected reduction in crashes if the countermeasures are implemented. The ADT is expected to increase 2%

QUESTION 9 The adjustment for the access point density is based on empirical studies indicating that for each access point per mile, the estimated FFS decreases by 0.25 mi/h, regardless of the type of median. Note that these access points are those that influence traffic flow and that access points that go unnoticed by drivers are not included in the calculation of the access point density. Therefore, what is the expected reduction (mph) in FFS when the access density is 4 access points per mile. (enter a positive value)
Question 35 24-h traffic count at a road section was observed to be 1000 vehicles on a Tuesday in the month of July. If daily adjustment factor for Tuesday is 1.121 and monthly adjustment factor for July is 0.913, the Annual Average Daily Traffic (in veh/day, round off to the nearest integer) is
On an expressway, it was recorded that there is an average of 22 vehicles that are passing the said portion of the highway in every minute. Evaluate the value of the flow of traffic on that day in veh/hr.
vehicles arrive at roadway section at a rate of 300 veh/h according to a Poisson distribution. During a 40 minute interval, how many of the headways will be greater than 4 seconds on average?
