Traffic-calming measures have been widely used in urban areas, aiming sometimes to reduce vehicle flow rates but primarily to reduce speed and, hence, the number and severity of traffic accidents. The one-way priority working road narrowing (throttle... Read More about Effect of road narrowing on junction capacity using microsimulation.

Drivers’ lane utilization for UK motorways (2012)
Journal Article
Yousif, S., Al-Obaedi, J., & Henson, R. (2013). Drivers’ lane utilization for UK motorways. Journal of Transportation Engineering, 139(5), 441-447. https://doi.org/10.1061/%28ASCE%29TE.1943-5436.0000531

Lane utilization represents how the rate of traffic flow is distributed among the available number of lanes in a given section. This utilization or split is affected by several factors including traffic flow rates as well as the presence and amount o... Read More about Drivers’ lane utilization for UK motorways.

Microsimulation model for motorway merges with ramp-metering controls (2012)
Journal Article
with ramp-metering controls. IEEE Transactions on Intelligent Transportation Systems, 13(1), 296-306. https://doi.org/10.1109/TITS.2011.2169792

This paper presents a newly developed microsimulation model for motorway merge traffic, focusing on issues that relate to ramp-metering (RM) control and its effectiveness. The model deals with general and more specific drivers’ behavioral tasks, such... Read More about Microsimulation model for motorway merges with ramp-metering controls.

Modeling factors influencing the capacity of motorway merge sections controlled by ramp metering (2011)
Presentation / Conference
sections controlled by ramp metering. Presented at 6th International Symposium on Highway Capacity and Quality of Service, Stockholm, Sweden

This paper focuses on studying factors which are likely to affect motorway merge capacity when ramp metering controls are in use. A newly developed traffic micro-simulation model has been used for this purpose and the well known ALINEA and Demand-Cap...
