  In this information era commuters prefer to know a reliable travel time to
plan ahead of their journey using both public and private modes. In this
direction reliability analysis using the location data of the buses is
conducted in two folds in the current work; (i) Reliability analysis of a
public transit service at route level, and (ii) Travel time reliability
analysis of a route utilizing the location data of the buses. The reliability
parameters assessed for public transit service are headway, passenger waiting
time, travel speed, and travel time as per the Service Level Benchmarks for
Urban Transport by the National Urban Transport Policy, Government of India.
And travel time reliability parameters such as Buffer Time Index, Travel Time
Index, and Planning Time Index are assessed as per Federal Highway
Administration, Department of Transportation, U S. The study is conducted in
Tumakuru city, India for a significant bus route in a limited data sources
scenario. The results suggest that (i) the Level of Service of the public
transit service needs improvement. (ii)around 30% excess of average travel time
is needed as buffer time. (iii) more than double the amount of free flow travel
time must be planned during peak hours and in the worst case. In the future,
the analysis conducted for the route can be extended for citywide performance
analysis in both folds. Also, the same method can be applied to cities with
similar demographics and traffic-related infrastructure.
