METEN IS WETEN!? FLUCTUATIES IN UTILITAIR FIETSVERKEER OP WERKDAGEN EN CONSEQUENTIES DAARVAN VOOR DE WAARNEMINGSOPZET

The plans for facilities for bicycles need to be based upon a precise insight into bicycle traffic volumes. This paper aims at an enlargement of the insight into fluctuations of daily and hourly bicycle volumes and into their consequences for planning, and the interpretation of especially short observations. The research is focussed on utility flows (commuting and school traffic) on weekdays. Weekdays are classified by four seasons and by school days or non school days. Most of the standard deviations from daily flows per calender year are at most 35 per cent. Values for the spring season are lower. Therefore, spring seems to be the most suitable season for short operations. Due to apparent differences the interpretation of the percentages of daily volumes per day hour should be made per season. The estimation of daily volumes by visual counts during a few hours by means of fixed conversions incorrectly neglects the considerable daily fluctuations. These fluctuations can be made visible by means of a confidence interval. This item needs further research. (Author/TRRL)
