Origin-Destination Trips by Purpose and Time of Day from mobile CDR: A Case of Yangon City

Abstract

Understanding the distribution of origin-destination trips by purpose is essential for activity-based travel demand management and future transport planning. This paper aims to identify origin-destination trips by purpose and time of day, based on the usage of their cell phone. In order to derive reasonable origin-destination trips by purposes, it is important to identify activity types such as home, work, and other stay locations. Trips are typically extracted using consecutive stay points and classified according to purpose, with home-based work (HBW), home-based other (HBO), and non-home-based trips (NHB). Home-based other trips are three times more likely than home-based work trips due to the inclusion of many types of other activities. Most people tend to make home-based trips during in the morning peak and evening peak periods. CDR data has captured users’ daily trip chains and has provided for the improvement of existing urban trip models and applied to mitigating congestion.
