. PROPOSED ARCHITECTUREFig.2: Proposed ArchitectureComparison of proposed architecture with ola architectureA. Present ArchitectureTime Lag:-Being most used still ,most shuttl apps likeola,uber shows a significant time delay while trackingcabs,thus results to an inaccurate time estimation. This is notvery serious issue for the individual rides but when it comes toshared rides, this time delay can lead to wrong assumption ofposition and estimated time left for the cab to arrive to user’slocation.Fig.3:Present ArchitectureB. Proposed ArchitectureDue to implementation of Kalman filter algorithm, itautomatically resolves this problem to the great extend by
