For a specific rural road segment in northeast Colorado, the total number of crashes as well as the number of fatal crashes have been recorded. Using the data provided with a traffic analysis within two standard deviations (or 95% confidence interval), determine if this site should be flagged for further study. Data: Length of road segment = 2 mi. AADT = 11,350 veh/day Total number of injury crashes for past 5 years = 55 Total number of fatal crashes for past 5 years = 5 Total number of property-only crashes for past 5 years = 100 Average number of statewide injury crashes for rural roads over past 5 years = 1.30 per 106 VMT Average number of statewide fatal crashes for rural roads over past 5 years = 0.02 per 106 VMT Average number of statewide property only crashes for rural roads over past 5 years = .033 per 106 VMT Weighted average crash rate of injury crashes for rural Colorado roads = 3 Weighted average crash rate of fatal crashes for rural Colorado roads = 8 Weighted…

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?

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.

The average number of collisions on Rt. 116 in South Deerfield is 15 per year. To address the high crash rate, a signal has been installed to make right-of-way explicit. The number of accidents in the following year was 9. MassDOT desires to know with how much confidence this reduction of accidents can be attributed to anything other than random chance.
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%

Can someone please show me how to solve this step by step. Thank you Suppose you are hired by the UHM Transportation and Traffic Lab (TTL) to analyze vehicle arrivals at one lane of the interchange bridge connecting I-25 and I-40 for the period from 12:00am to 4:00am in a weekday. It is known that vehicle arrivals follow a Poisson process at this location. There is a single-loop detector embedded on this lane at the end of the interchange bridge. Since you do not want to go to the bridge to count vehicles at this time period, you decided to use the loop detector data for the analysis. Of the 720 20-second intervals (the loop detection system stores data every 20 seconds), 508 intervals were identified to have at least one vehicle detected. Assume the loop detector is free of error. Please estimate the vehicle arrival rate (vehicles per second) for this lane. With the estimated arrival rate, please calculate the probability of having three or more vehicles detected in a 20-second…
