Abstract

Public transport operation is inherently connected with uncertainty, starting from schedules created for hypothetical operational conditions and demand levels, operational disturbances, dynamic real demand uncertainty and on complex interactions between different lines and transport modes ending. In this context the realisation of the general public transport objective: maintenance in the long-term horizon the guaranteed mobility standards in the city and their surroundings with essential reduction of transport operational negative impacts, calls for Advanced Public Transportation System (APTS) based dedicated approach. In this paper the exploration of Intelligent and Integrated DISpatching CONtrol (DISCON) method capabilities using new available in APTS capabilities was proposed. The uncertainty and stochastic aspects visible in public transport operation create the demand for dedicated intelligent dispatching robust control proposals. The APTS monitoring and surveillance tools and effective communication media make it possible to realize it in "control by opportunity" mode and with dynamic intelligent control feedback. In this paper DISCON robust dispatching real-time control proposals are presented. The first in LQG robust Kalman filter based control perspective and existence of control and state operational constraints. The second one based on cooperation with multi-criteria PIACON traffic control method as multi-criteria individual traffic public transport integrated approach with compromise solutions represented by so called "reference trajectory". In the last case the necessary control actions are recognized by real-time detection of the bus arrival to the signalised intersection and evaluation of its measure off-schedule deviations and bus load. Next the dynamic trade-offs with conflicting intersection users demands and service standards are established by PIACON control method and admissible priority control options in terms of so called "reference trajectory" for 1):DISCON control method are proposed. Illustrative practical examples for all new DISCON options are presented. (C) 2013 The Authors.
