A General Activity-based Methodology for Simulating Multimodal Transportation Networks during Emergencies

Paper + lecture. Many possible emergency conditions, including evacuations, negatively affect the urban transportation system by substantially increasing the travel demand and/or reducing the supplied capacity. We develop a new, general and efficient methodology suitable for simulating multimodal transportation systems subject to a wide range of...

An Activity-Based Multimodal Model Structure to assess Transportation Management Strategies for Urban Emergencies

There are many kinds of disasters that can severely impact the transportation system of an urbanized region. Transportation authorities therefore need to develop management strategies to adequately deal with such emergencies. In this paper, we discuss the structure of a simulation model that can be used to assess a candidate strategy. We model...

Flexible public transport modelling for large urban areas

When modelling the choice of making multi-modal trips, many travel demand models lack flexibility in the specification of modes and consistency in the choice process. This causes problems in modelling the usage of the complex public transport systems of large urban areas. In this abstract, we apply the supernetwork approach to develop a route...

A Flexible Approach towards Public Transport Modelling in Travel Demand Models

Public transport systems create large numbers of possible combinations of public and private modes that travellers can choose to use. As a consequence, current travel demand models face problems related to flexibility in the modelling of how travellers value and use modes, consistency in the choice process and computational efficiency. To...
