Vliv třídy rozdělení časových odstupů na kapacitu neřízených křižovatek

Original language description

When calculating the capacity of uncontrolled intersections, there is widely used method of critical time gaps. These time gaps hasa stochastic nature and as random variables are therefore appropriately statistically distributed. It is commonly assumed these gaps have an exponential probability distribution that corresponds to a known Poisson distribution of vehicle occurrence within a certain time interval. In real transport systems, however, this assumption is almost never fulfilled, except for extremely low traffic flow densities. We show in this paper that as suitable alternatives can be considered Gamma distribution, log-normal distribution or inverse Gaussian distribution.
