Examining the limitations for visual angle-car following models (2009)
Presentation / Conference
Al-Obaedi, J., & Yousif, S. (2009, January). Examining the limitations for visual angle-car following models. Presented at Universities Transport Studies Group 41st Conference, University College London

Visual angle car following models assume fixed values (thresholds) for the angular velocity (∆Ө/∆t) over which the driver of the following vehicle is affected by the leading vehicle. This paper explains the advantages and limitations of such models... Read More about Examining the limitations for visual angle-car following models.

Validation of a mathematical model to estimate turning movements as roundabouts using field data (2007)
Presentation / Conference
Yousif, S., & Razouki, S. (2007, January). Validation of a mathematical model to estimate turning movements as roundabouts using field data. Presented at Universities Transport Studies Group - 39th Annual Conference, University of Leeds

In this paper, a mathematical model was presented and used to determine turning movements at roundabouts based on field data. Assumptions were made in order to simplify the model; such as no U_turns from and to the same arm of a roundabout, total tr...

Comparison of accepted gaps for different on-street parking designs (2000)
Presentation / Conference
Purnawan, & Yousif, S. (2000, October). Comparison of accepted gaps for different on-street parking designs. Presented at 5th ISSM, Paris, France

Potential problems could arise when drivers leave their parking stalls and merge into the main traffic stream. These problems could partly be attributed to finding acceptable gaps to merge into with safety and without causing undue difficulties to f...

On-street parking manoeuvres and their effects on design (1999)
Presentation / Conference
Purnawan, & Yousif, S. (1999, March). On-street parking manoeuvres and their effects on design. Presented at 4th ISSM, Kassel, Germany

Vehicle manoeuvres when entering or leaving on-street parking can be a contributory factor to causing congestion. Little explicit attention has been given to these manoeuvres and their indirect potential effects on the moving traffic. In the design...

A study into urban roadworks with shuttle-lane operation (1998)
Presentation / Conference
Samoail, N., & Yousif, S. (1998, April). A study into urban roadworks with shuttle-lane operation. Presented at Proceedings of the 3rd Institute of Mathematics and its Applications International Conference on Mathematics in Transport Planning and Control, Cardiff, UK

In urban areas where roadworks are required, single lane shuttle operation is applied, especially where there is limited road space. There are operational problems relating to the site such as site geometry, visibility, length of roadworks zone, pos... Read More about A study into urban roadworks with shuttle-lane operation.
