... value appears too low on two-lane roads. The threshold value for not rejecting the hypothesis of exponential tail is about 8 sec. On low-speed roads lower threshold values may be possible. Miller (16) also found t0 = 8 sec appropriate. Because of large t0 , a headway distribution that has positive s ...

I. Range and Standard Deviation a. The most basic way to describe
... b. Note the notation is different: the sample standard deviation uses “s” while the population standard deviation uses “σ” and “x-bar” is replaced with μ. i. Similarly, sample variance is “s2” and population variance is “σ2.” c. Note also this equation uses “N” rather than “n – 1.” Why does the samp ...

What is Probability? - University of Vermont
... In other words, probabilities are always bounded by a minimum of 0.0 and a maximum of 1.0. A probability of 0.0 represents an event that will never happen, and a probability of 1.0 represents an event that will always happen.8 We all have intuitive and 2 (= pedestrian crosses safely).

The Normal Distribution of Errors Computational Physics
... We may think of a measurement as being the result of a process. Each step in the process may lead to a small error with a probability distribution. Sum error over all steps to get final error leads to normal distribution no matter what the error on the individual steps works out to be. Generally exp ...
