Travel Time Reliability Analysis on Selected Bus Route of Mysore Using GPS Data

This research study aims at evaluating the travel time reliability indices like Buffer Time Index, Planning Time Index and Travel Time Index over space and time on selected city bus route of Mysore city, India. Also, this study focuses on developing the correlation models between the bus journey speed and flow for different type of urban roadway conditions. These models are observed to be performing better and hence can be used for predicting traffic volumes for similar roadway conditions when traffic data are not available from field. Further, the variation of volume-to-capacity (V/C) with travel time reliability indices is also studied in detail. The k-means clustering analysis is performed for classifying the reliability measures with respect to V/C and Coefficient of Variation. It is expected that the developed reliability measures may be useful for defining level of service for bus routes in class-II cities (cities with lesser population than metropolitan cities).
