PRACTICAL METHODOLOGY FOR DETERMINING DYNAMIC CHANGES IN BUS TRAVEL TIME (ABRIDGMENT)

Research undertaken to develop and examine two methods of treating bus travel time-(a) measurement and (b) processing and analysis for planning needs-is reported. These methods are intended mainly for the scheduler responsible for scheduling buses to trips so as to take into account any dynamic changes in bus travel time. The motivation for the research comes from the existing system at Egged (the Israel National Bus Carrier), which uses a single mean value for bus travel time (for a given bus line) for all days of the year. The method chosen for data collection on bus travel time is based on the use of the tachograph, which is currently an integral part of bus equipment. The tachograph allows for a current report on departure and arrival times of trips through the turn of a special knob by the driver. In comparison with other information systems being tested today, the tachograph is simple and inexpensive to use. The accumulated data on bus travel time are transferred by use of a statistical method to calculate means and standard deviations for three cross sections: daily, weekly, and seasonal. The criteria for the statistical method are that it be simple, flexible, systematic, and practical so that the outcome will be compatible with the objective of planning work schedules for buses.
