Dynamic congestion charging: Investigating boundary effects when applying low-revenue tolls. (2015)
Journal Article
Stewart, K., & Ge, Y. (2015). Dynamic congestion charging: Investigating boundary effects when applying low-revenue tolls. International Journal of Transportation, 3(2), 17-30

This paper investigates the impact of realistic congestion charging regimes where undesired boundary effects of imposing charges may occur and may be both temporal and spatial. Tolling regimes are developed with the primary aim to reduce system cost... Read More about Dynamic congestion charging: Investigating boundary effects when applying low-revenue tolls..

Optimising time-varying network flows by low-revenue tolling under dynamic user equilibrium. (2014)
Journal Article
Stewart, K., & Ge, Y. (2014). Optimising time-varying network flows by low-revenue tolling under dynamic user equilibrium. European journal of transport and infrastructure research, 14, 30-45

This paper presents a dynamic congestion charging framework that includes a dynamic user equilibrium (DUE) network model to optimize a tolling scheme, whose objective(s) may be determined by the transport planner. The framework presented may be utili... Read More about Optimising time-varying network flows by low-revenue tolling under dynamic user equilibrium..

Investigating undesired spatial and temporal boundary effects of congestion charging. (2014)
Journal Article
Ge, Y., Stewart, K., Sun, B., Ban, X., & Zhang, S. (2014). Investigating undesired spatial and temporal boundary effects of congestion charging. Transportmetrica B: Transport Dynamics, 1-23. https://doi.org/10.1080/21680566.2014.961044

Two types of reported problems are related to the existing congestion charging projects that levy traffic only in a certain area within one or a few time periods during the day. One is that travellers depart earlier or later than a charging period to... Read More about Investigating undesired spatial and temporal boundary effects of congestion charging..

Cycle lanes: their effect on driver passing distances in urban areas. (2014)
Journal Article
Stewart, K., & McHale, A. (2014). Cycle lanes: their effect on driver passing distances in urban areas. Transport, 29(3), 307-316. https://doi.org/10.3846/16484142.2014.953205

The current literature in the field of cycle lanes has often shown contradictory evidence as to the benefits and risks of cycle lanes and previous work has specifically shown that on higher speed roads, drivers may pass closer to a cyclist when a cyc...

Presentation / Conference
Martinez, E., & Stewart, K. (2012, January). Modelling behavioural responses to road tolling. Paper presented at 44th Annual Conference of the University Transport Study Group

Microsimulation modelling is a widely accepted tool in the assessment of the impact of a wide variety of transport schemes. The robustness of a model depends on the accuracy with which traffic behaviour is represented. In the case of road pricing t... Read More about Modelling behavioural responses to road tolling..
