In urban contexts, the adoption of policies for promoting the use of public transport systems represents a useful tool for decision-makers in order to reduce environmental impacts related to private car use. In particular, in high density contexts the related values of travel demand can be satisfied efficiently by means of high quality rail systems. It is worth noting that, in case of breakdowns, since generally the faulty train can not be overtaken and its removal could be extremely difficult especially in metropolitan systems with two separate tunnels, the re-establishment of regular service could involve huge times inconsistent with traveller requirements. Hence, the emergency management has to take into account of effects on travel demand. In this framework, our proposal is to analyse these effects for different levels of degraded services in order to define the best strategy to adopt for minimising user discomforts. In particular, we propose to extend papers proposed in the literature by introducing capacity constraints of rail vehicles in order to provide more realistic simulated effects.

Abstract
In urban contexts, the adoption of policies for promoting the use of public transport systems represents a useful tool for decision-makers in order to reduce environmental impacts related to private car use. In particular, in high density contexts the related values of travel demand can be satisfied efficiently by means of high quality rail systems. It is worth noting that, in case of breakdowns, since generally the faulty train can not be overtaken and its removal could be extremely difficult especially in metropolitan systems with two separate tunnels, the re-establishment of regular service could involve huge times inconsistent with traveller requirements. Hence, the emergency management has to take into account of effects on travel demand. In this framework, our proposal is to analyse these effects for different levels of degraded services in order to define the best strategy to adopt for minimising user discomforts. In particular, we propose to extend papers proposed in the literature by introducing capacity constraints of rail vehicles in order to provide more realistic simulated effects. Finally, the proposed approach has been applied in the case of Linea 1 of metro system of Naples (Italy).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
