Do “hyper-travellers” exist? – Initial results of an international survey on public transport user behaviour. (2010)
Presentation / Conference Contribution
Fonzone, A., Schmoecker, J.-D., Bell, M. G. H., Gentile, G., Kurauchi, F., Noeckel, K., & Wilson, N. H. M. (2010, July). Do “hyper-travellers” exist? – Initial results of an international survey on public transport user behaviour. Paper presented at 12th World Congress on Transport Research

Transport modelling – both in traffic and transit fields – has been traditionally based on the assumption of the utility maximization principle. In public transport networks with high frequency services this has led to “hyperpath” route choice models...

Seat capacity and hyperpath choice on-board: alight or remain seated? (2010)
Presentation / Conference Contribution
Schmoecker, J.-D., Shimamoto, H., Kurauchi, F., Fonzone, A., & Bell, M. G. H. (2010, July). Seat capacity and hyperpath choice on-board: alight or remain seated?. Paper presented at 12th World Congress on Transport Research

The rationale for the definition of a set of paths referred to as “hyperpath” is that some uncertainty (for example waiting time) means that the choice of a specific option is not being pre-determined. Rather the choice process is assumed to occur on... Read More about Seat capacity and hyperpath choice on-board: alight or remain seated?.

Dynamic route choice in a congested transit network with uncertain carriers’ arrival times (2010)
Presentation / Conference Contribution
Trozzi, V., Bell, M. G. H., Gentile, G., & Fonzone, A. (2010, July). Dynamic route choice in a congested transit network with uncertain carriers’ arrival times. Paper presented at 12th World Congress on Transport Research

The purpose of this paper is to investigate the possibility of exploiting the hyperpath paradigm within the framework of dynamic assignment to model the route choice in a congested transit network, where passengers might encounter queues at transit s...

Selecting potentially optimal routes through optimistic and pessimistic node potentials. (2010)
Presentation / Conference Contribution
Fonzone, A., Schmoecker, J.-D., & Bell, M. G. H. (2010, July). Selecting potentially optimal routes through optimistic and pessimistic node potentials. Paper presented at The Third International Symposium on Dynamic Traffic Assignment

Existing assignment or route guidance models are not suitable to represent travellers` choices or to advise travellers in networks in which each link may be subject to failure with an unknown probability. A heuristic approach to select potentially op... Read More about Selecting potentially optimal routes through optimistic and pessimistic node potentials..

Potentially optimal paths and route choice in networks with arc delays. (2010)
Presentation / Conference Contribution
Fonzone, A., Schmoecker, J.-D., & Bell, M. G. H. (2010, April). Potentially optimal paths and route choice in networks with arc delays. Paper presented at 5th IMA International conference on Mathematics in Transport

The shortest path problem has been widely studied in graph theory and its solutions have been largely used in the transport field, both in assignment and vehicle navigation applications. Solutions have been proposed under different assumptions concer... Read More about Potentially optimal paths and route choice in networks with arc delays..

Schedule-based hyperpath approaches to transit assignment: the impact of imperfect information. (2010)
Presentation / Conference Contribution
Rochau, N., Bell, M. G. H., Noeckel, K., & Fonzone, A. (2010, April). Schedule-based hyperpath approaches to transit assignment: the impact of imperfect information. Paper presented at 5th IMA Conference on Mathematics in Transport

In a schedule-based capacitated transit network we analyze optimal passenger strategies, where a strategy is a ranked set of services at each interchange in the transit network. The passenger is assumed to take the first ranked service unless this is... Read More about Schedule-based hyperpath approaches to transit assignment: the impact of imperfect information..

Bounded rationality in hyperpath assignment: the locally rational traveller model. (2010)
Presentation / Conference Contribution
Fonzone, A., & Bell, M. G. H. (2010, January). Bounded rationality in hyperpath assignment: the locally rational traveller model. Presented at 89th Annual TRB Meeting

The concepts of optimal strategy and hyperpath were introduced in the transport field under the paradigms of equilibrium and expected utility theory, which assume perfect rationality. The initial scope for hyperpaths was frequency-based transit assig... Read More about Bounded rationality in hyperpath assignment: the locally rational traveller model..

Attacker-defender models and road network vulnerability (2008)
Journal Article
Bell, M. G. H., Kanturska, U., Schmocker, J. D., & Fonzone, A. (2008). Attacker-defender models and road network vulnerability. Philosophical Transactions A: Mathematical, Physical and Engineering Sciences, 366, 1893-1906. https://doi.org/10.1098/rsta.2008.0019

The reliability of road networks depends directly on their vulnerability to disruptive incidents, ranging in severity from minor disruptions to terrorist attacks. This paper presents a game theoretic approach to the analysis of road network vulnerabi... Read More about Attacker-defender models and road network vulnerability.

Improving reliability through multi-path routing and link defence: an application of game theory to transport. (2008)
Book Chapter
Kanturska, U., Schmoecker, J. D., Fonzone, A., & Bell, M. G. H. (2008). Improving reliability through multi-path routing and link defence: an application of game theory to transport. In Game Theoretic Risk Analysis of Security Threats (199-229). BMC

This paper looks at the vulnerability of transportation networks against minor (e.g. demonstrations) and major (e.g. terrorists attacks) incidents by using an attacker-defender model which applies the game theoretic approach proposed by Bell (2000)....
