The current urbanization and motorization have caused a gradual negative impact on the existing transport infrastructure in Yangon City. Currently, the road network throughout Yangon operates at or above its desired capacity during the peak periods. At present, there are over 62,886 registered taxis operating in Yangon City. These taxis provide two different services to passengers: non-metered taxi (traditionally hailed on the street) service and metered taxi (on demand) service. Private cars and taxis constitute 70% of the modes of transport in Yangon City; this may lead to traffic congestion. However, there is lack of relevant data and taxi trip pattern information on how taxi service is related to traffic congestion. Therefore, studies on taxi surveying using Global Positioning Systems (GPS) need to be conducted, and investigations on the effect of taxi services on traffic congestion from these GPS data need to be performed. This study explores the comparison between hourly and daily trips’ frequencies as well as spatial and temporal variations of taxi trips between the two services. Field survey data collected through the GPS and Geographic Information System (GIS) were used to estimate the different taxi travel times that can be applied in predicting the occupied and vacant times in the study area. The specific objective of this research is to examine vacant taxi movement and stationary time (parking time and congestion time) of the two services to quantify the impact of taxi travel time on traffic congestion in Yangon. Moreover, by knowing how the two services vary in terms of operation, the main solution for reducing the congestion in Yangon City can be established. Further, the taxi stationary duration information is useful for knowing the taxi trip hotspot points in each township in Yangon. This may lead to support in defining proposed taxi stands in Yangon City.
