Item Spatiotemporal Speed Characterization of Bus Rapid Transit System(Springer Science and Business Media Deutschland GmbH, 2024) Halyal, S.; Angadi, V.S.; Mulangi, R.H.Performance analysis of an urban transportation system, particularly a bus rapid transit system (BRTS), must report on its operations and dependability. The BRTS performance analysis includes many factors, including speed, directly impacting how the system functions and serves commuters. This study employs an experimental technique on a standardized basis to remark on the performance of the Hubballi–Dharwad BRTS by estimating the corridor's average speed at various spatial and temporal fluctuations. The BRTS route chosen included segregated (exclusive traffic environment) and unsegregated (mixed traffic environment) stretches. The current study primarily employed video graphics-based and manual surveys to collect data on identified spatial and temporal trends at different BRTS bus stations. The primary data required consists of dwell time (DT)-based data at each station, summarizing the total time a bus services a station for a unit of time, signal cycle data, and section speed, which corresponds to the speed of the buses between two BRT bus stations while observing spatial and temporal trends. The acceleration and deceleration rates were calculated using the section speed, followed by the acceleration and deceleration time. The addition of delays, errors, and bus congestion resulted in the average speed of various stretches. The average section speeds then facilitated the average facility speed. The variations in average section speed between stations were graphically presented, both spatially and temporally, which gave the conclusion that there was a higher section speed in the segregated stretch and a lower rate in the unsegregated stretch, followed by a higher speed in the off-peak hours and lower speed in the peak hours. The Level of Service (LOS) was developed for complete study sections considering the average facility speeds with and without the impedance, and the results were compared. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
