The vehicle navigation problem studied in Bell (2009) is revisited and a time-dependent reverse Hyperstar algorithm is presented. This minimises the expected time of arrival at the destination, and all intermediate nodes, where expectation is based on a pessimistic (or risk-averse) view of...

A recently proposed frequency-based maritime container assignment model (Bell et al., 2011) seeks an assignment of full and empty containers to paths that minimises expected container travel time, whereas containers are in practice more likely to be assigned to minimise expected cost. A...

On 17 February 2003, London introduced a pioneering congestion-charging scheme. The impact on traffic was sudden and dramatic.For example, car movements within the congestion-charging zone (21km2) were reduced by about 30%. However, the impact on otheractivities, such as retail business within...

This paper presents an analysis of shopping trips into London's central shopping district (Oxford Street area) before and after the introduction of the congestion charging scheme in February 2003. In collaboration with a major department store, three surveys have been conducted in order to...

On 17 February 2003, London introduced a pioneering congestion-charging scheme. The impact on traffic was sudden and dramatic. For example, car movements within the congestion-charging zone (21 km2) were reduced by about 30%. However, the impact on other activities, such as retail business...

This paper proposes a frequency-based assignment model that considers travellers probability of finding a seat in their perception of route cost and hence also their route choice. The model introduces a "fail-to-sit" probability at boarding points with travel costs based on the likelihood of...

Areas subject to natural or man-made disasters, such as earthquakes, fires, floods or attacks, are reliant on the residual transport network for the rescue of survivors and subsequent recovery. Pre-disaster planning requires assumptions about how the transport network may degrade. This paper...

This paper studies job assignments for automated guided in container terminal settings under various conditions of uncertainty. An introduction to their operation is provided, along with a flexible dispatching algorithm, suitable for real-time control of AGVs. Using these concepts a new AGV...
