Hydraulic characteristics of siphonic roof drainage outlets (2008)
Thesis
Rains, J. Hydraulic characteristics of siphonic roof drainage outlets. (Thesis). University of Salford

Siphonic roof drainage uses an innovative hydraulic design to increase the efficiency of rainwater disposal. The roof outlet is a critical component of the system and not only promotes and sustains priming of the system but also controls the depth...

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...

Development of traffic micro-simulation for on-street parking facilities (2005)
Thesis
Purnawan, P. Development of traffic micro-simulation for on-street parking facilities. (Thesis). Salford : University of Salford

Observations at several on-street parking areas showed that parking and imparking processes could produce severe traffic interruptions if parking locations were not designed properly. This study is aimed to develop an on-street parking simulation... Read More about Development of traffic micro-simulation for on-street parking facilities.

Motorway roadworks: effects on traffic operations (2002)
Journal Article
Yousif, S. (2002). Motorway roadworks: effects on traffic operations. Highways and transportation, 49(4), 20-22

This paper examines traffic operations at the approaches to motorway roadwork sites in the North West of England and focuses on some of the parameters affecting both safety and capacity. The trade–off between capacity and safety at motorway roadwork... Read More about Motorway roadworks: effects on traffic operations.

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...

A study into on-street parking: effects on traffic congestion (1999)
Journal Article
Yousif, S., & Purnawan. (1999). A study into on-street parking: effects on traffic congestion. Traffic engineering & control, 40(9), 424-427

This paper describes the characteristics of vehicle manoeuvres when entering or leaving on-street parking. Those manoeuvres are often ignored by traffic engineers in the design process and the evaluation of traffic management schemes. However, they...

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.

Development of a micro-simulation model for motorway roadworks with the use of narrow lanes and lane closure schemes
Thesis
Nassrullah, Z. Development of a micro-simulation model for motorway roadworks with the use of narrow lanes and lane closure schemes. (Thesis). University of Salford

This study presents a newly developed micro-simulation model for motorway roadwork sections to evaluate the efficiency of different temporary traffic management schemes (TTMSs) such as the use of narrow lanes, offside and inside lane closures. The ef... Read More about Development of a micro-simulation model for motorway roadworks with the use of narrow lanes and lane closure schemes.

Close following behavior: Testing visual angle car following models using various sets of data
Journal Article
Yousif, S., & Al-Obaedi, J. Close following behavior: Testing visual angle car following models using various sets of data. Transportation Research Part F: Traffic Psychology and Behaviour, 14(2), 96-110. https://doi.org/10.1016/j.trf.2010.11.001

Visual angle car following models have previously been proposed in modeling drivers’ “close following” behavior particularly in traffic simulation models. These models use relative speeds and relative spacings between successive vehicles, but they ar...

Traffic operations at on-street parking facilities
Journal Article
Yousif, S., & Purnawan. Traffic operations at on-street parking facilities. Proceedings of the ICE - Transport, 157(3), 189-194. https://doi.org/10.1680/tran.2004.157.3.189

This study reports on the findings based on observations from sites with parallel and angle parking layouts. The main parameters under consideration were the manoeuvre time for parking or unparking and the gap acceptance to merge into the traffic...

The use of visual angle in car following traffic micro-simulation models
Presentation / Conference
Al-Obaedi, J., & Yousif, S. The use of visual angle in car following traffic micro-simulation models. Presented at International Built & Human Environment Research Week (IRW)., Salford, Greater Manchester

This paper presents a detailed literature review on car following models and methods used in describing the behaviour between two drivers of successive vehicles travelling in a traffic stream. The paper then concentrates on presenting a proposed car... Read More about The use of visual angle in car following traffic micro-simulation models.
