Building the Origin-Destination Matrix under General Traffic Conditions and Using it to Generate Passenger Origin-Destination Pairs

摘要

This series of articles is based on lecture notes used by the author in the course entitled: "Selected Topics in Mechatronics: Elevator Traffic Analysis and Design" that was delivered at the Mechatronics Engineering Department at The University of Jordan (Amman, Jordan) to undergraduate Mechatronics Engineering students. This paper presents a methodology for generating the origin-destination matrix from the user requirements specification under general traffic conditions. The user requirements describing the traffic conditions can be specified by the user, expressed as the percentage arrival rate (AR%), the mix of incoming traffic, outgoing traffic and inter-floor traffic. This paper derives equations that can be used to combine the mix of traffic, the floor arrival percentages and the floor population percentages into an origin-destination (OD) matrix. The origin destination matrix is then adjusted and normalised in order to account for rational passenger behaviour (i.e., a passenger will not travel to the same floor that he/she is at). The origin-destination matrix can be used for the generation of random passenger origin-destination pairs (which is necessary when using the Monte Carlo Simulation (MCS) method to calculate the round trip time or in elevator traffic software). A numerical example is shown for this at the end of the paper.
