11/03/2010 Optimal Mainstream Traffic Flow Control of Large Scale Motorway Networks Speaker: Prof. Markos Papageorgiou, Technical University of Crete Abstract: The continuously increasing daily traffic congestions on motorway networks around the world call for innovative control measures that would drastically improve the current traffic conditions. Mainstream traffic flow control (MTFC) is proposed as a novel and efficient motorway traffic management tool, and its possible implementation and principal impact on traffic flow efficiency is analysed. Variable speed limits, suitably operated and enforced, is considered as one (out of several possible) way(s) for MTFC realisation, either as a stand-alone measure or in combination with ramp metering. A previously developed, computationally efficient software tool for optimal integrated motorway network traffic control including MTFC is applied to a large-scale motorway ring-road. It is demonstrated via several investigated control scenarios that traffic flow can be substantially improved via MTFC with or without integration with coordinated ramp metering actions.
15/04/2010 The tragedy of cooperation within couples Decision making and mobility Speaker: André de-Palma , Ecole Normale Supérieure de Cachan ABSTRACT Individuals in couples tend to behave cooperatively and empirical evidence suggests that their decisions are Pareto efficient. However, most of the literature has examined couples in isolation without studying the consequences of their decisions for society as a whole. This paper develops a theoretical model to study trip-timing decisions of couples in the context of the morning commute by automobile when there is traffic congestion. Three settings are compared: (a) individuals living alone, (b) couples living together who make independent, non-cooperative decisions, and (c) couples who make cooperative decisions. Finally, we briefly discuss the implications of these results on the optimal manner to determine control and pricing. BIO André de Palma has a PhD in Physics and one in Economics. He is a specialist in transportation economics, and industrial organization. He has developed the software METROPOLIS, a dynamic model of traffic congestion. He has published more than 200 articles in Transportation, Economics, and Operations Research Journal, and has written/edited 5 books. He is currently teaching at Ecole Normale Supérieure de Cachan and at Ecole Polytechnique, in Paris. He is a senior member of Institut universitaire de France.
