Abstract:

The paper presents the analysis results of measurements recorded
by road traffic and noise monitoring station. The station is located
in a medium size town in Poland (Kielce) situated at the national road
to Cracow. The traffic flow was measured over the period between January
and December 2013 for twenty four hours a day. Statistical analysis
methods were used to determine the variability and uncertainty of the results.
The measurements from two vehicular lanes running towards the town and
two lanes running towards Cracow were analyzed. The variability of the
results was described using parameters such as the coefficient of variation
and positional variation. The results of vehicle traffic measurements were
used to simulate changes in the noise measurand variation within 1-hour
intervals. The Nordic Prediction Method was used for this purpose. It was
found that in most cases, the distribution of the tested variable was not
normal. Box plots were used to assess whether outliers data occurred in the
recorded results. The variability of noise and type A uncertainty was
evaluated.
