| Abstract: | Be it snow, volcanic ash or strikes, crisis events impose high costs on the air transportation system and society. Airlines have progressively learned to mitigate the irregular operations arising from such events through procedures such as Airport Collaborative Decision Making (A-CDM) for traffic flow and airport departure management; however the passenger's door-to-door journey during difficult times often remains unpleasant. Meta-CDM (Multimodal, Efficient Transportation in Airports and Collaborative Decision Making), aims to take a passenger-centric approach and to examine how airside and landside CDM can be interlinked with other transport modes to minimize the impact of severe disruptions. We provide an analysis of past successes and failures of passenger-centric operations, by investigating representative disruptive events. We focus on the links between different transportation modes and the practicalities of switching modes in a crisis situation. We analyze if and how passenger metrics could be used to measure the performance of an extended A-CDM concept. |

| Abstract: | South Asia and Southeast Asia have been connected for many centuries, with the degree of connectivity varying over time. This paper explores strengthening connectivity between the two subregions by identifying the missing links in transport connectivity. The paper is specifically concerned with the role of cross-border transport infrastructure investments. To this end, the author reviews all possible road and rail land corridors that would help create seamless transport connectivity. Missing gaps and corresponding transport infrastructure projects are identified, and projects are screened and prioritized. For the selected critical projects, the study recommends phased investments. |

| Abstract: | Design of container terminal operations is complex because multiple factors affect the operational perfor- mance. These factors include: topological constraints, a large number of design parameters and settings, and stochastic interactions that interplay among the quayside, vehicle transport, and stackside processes. In this research, we propose new integrated queuing network models for rapid design evaluation of container terminals with Automated Lift Vehicles (ALVs) and Automated Guided Vehicles (AGVs). These models offer the flexibility to analyze alternate design variations and develop insights. For instance, the effect of alternate vehicle dwell point policy is analyzed using state-dependent queues, whereas the efficient terminal layout is determined using variation in the service time expressions at the stations. Further, using embedded Markov chain analysis, we develop an approximate procedure for analyzing bulk container arrivals. These models form the building block for design and analysis of large-scale terminal operations. We test the model efficacy using detailed in-house simulation experiments and real-terminal validation by partnering with an external party. |

| Abstract: | Since 1989 and the regionalization of public transports in Belgium, the Société des transports intercommunaux de Bruxelles (STIB), i.e. the public operator of urban transport in Brussels, has undergone many changes, both structural and organizational. Meanwhile, the company has managed to improve its financial health in accordance with the objectives set by the regulatory transport authority, the Region of Brussels-Capital. The analysis of the system of actors shows that, in a principal-agent relationship characterized by high information asymmetry, the convergence of interests between the supervisory authority and the public company is neither natural nor automatic: it is built. This construction takes place at several levels and materializes incrementally, particularly through the management contract. In this regulatory system, the process organizing the dialogue between the company and the authority produces the desired beneficial effects, more than the legal value of the contract does. The interdependence between the actions of the Region and those of the STIB implies practices that can be described as a partnership. Finally, the analysis shows that the contractualization is not inconsistent with an evolution of the roles of each actor |
