The collected data included the GPS unit ID, latitude, longitude and the time at which each entry was recorded. The data were sent to a remote computer (through General Packet Radio Service) a real time at every 5 sec. After analyzing for data quality by removing any outliers, the next step was to extract the section wise travel time of the bus probes and the private vehicle. The total study stretch of 15 km was divided into 100 m subsections and travel time of bus probes and two-wheeler within each of these 150 sections were calculated. This process is repeated for all the 14 trips made.
