DEVELOPING A METHOD FOR MEASURING THE QUALITY OF A SAMPLE BASED TRIP LENGTH DISTRIBUTION FOR URBAN TRIP
Abstract: Trip Length
Distribution is an important part of Transportation Modelling. This
distribution is normally gotten from a sample. Thus, the Quality of the Sample
Based Distribution must be able to be measured. This paper present the result
of an attempt to develop a method to measure this quality. The research gave
the following result. Basic common measure related to the sampling is a maximum
acceptable error at a certain minimum confidence level. It has been found that
the Quality Measuring Method can not incorporate the error, since it deals with
a distribution pattern in which there is no single parameter value and the
error probability density function is not yet known. The proposed Sample
Quality Measuring Method is by calculating its Confidence Level based on the Goodness
of Fit Statistical Inference method, by using a 2 test.
The Confidence Level is equal to P(2,; where 2 = (Oi – Ei)2/ Ei and = k
– r – 1.
