The truck traffic on a highway can be describe as a Poisson process with a mean arrival rate of 1.5 trucks per minute. The weight of each truck is random and the probability that a truck is overloaded is 5%.
a.   What is the probability that there will be at least two trucks passing a weigh stat ion this highway in a 10-minute period? Define the random variable.
b.   What is the probability that at most one of the next 10 trucks stopping at the weigh station will be overloaded? Define the random variable.
c.   Suppose the weigh station will close for 30 minutes for lunch. What is the probability of overloaded trucks passing the weigh station during the lunch break? Define the random variable.

5. The occurrence of traffic accidents at an intersection is modeled as a Poisson process. Based on accident records at that intersection, a traffic engineer has determined that the average rate of accidents occurring at that intersection is once every three years. (a) What is the probability that no accident occurs at that intersection for a period of 5 years? (b) What is the probability that there is a traffic fatality at that intersection over a period of 3 years...

On a highway, vehicles pass according to a Poisson process with rate 1 vehicle per minute. Suppose that 25% of the vehicles are trucks and 75% of the vehicles are cars. Let NC(t) and NT(t) denote the number of cars and trucks that pass in t minutes, respectively. Then N(t) = NC(t) + NT(t) is the number of vehicles that pass in t minutes. Find E[N(10) | NT(10)=2] Find P[NC(10)=14 | N(10)=15]

Traffic flow is traditionally modeled as a Poisson Distribution. A traffic engineer monitors the traffic flowing through an intersection with an average of 9 vehicles per minute. What is the random variable X described above? Write the distribution of X using the standard notations.                                           What should be the variance and the standard deviation of the number of vehicles through the intersection within a minute?                       ...

Traffic on Rosedale Road in Princeton, NJ, follows a Poisson process with rate 6 cars per minute. A deer runs out of the woods and tries to cross the road. It takes the deer a random time (independent of everything else), uniformly distributed between 2 and 5 seconds, to cross the road. If there is a car passing while the deer is on the road, it will hit the deer with portability 2/3 (independent of everything else). Find the probability...
