A comparative study on the operational performance of four-leg intersections by control type
( Elsevier Ltd , 2018 , Article)The selection of proper control types at intersections at the planning stage is an important concern considering the difficulty in comparing the performance of different control types. Therefore, several manuals proposed ... -
Attitudes towards road safety among pre-drivers: The case of Qatar
( IEOM Society , 2018 , Conference)A preliminary study involving school students aged 12-18 years attempted to test whether there is difference in attitudes towards road safety between Arab and non-Arab respondents. The sampled participants were categorized ... -

Drivers’ estimation of their travelling speed: a study on an expressway and a local road
( Taylor and Francis Ltd. , 2019 , Article)Correctly estimating the travelling speed is essential for safety on the roads to ensure safer interactions with other drivers and to avoid violations of traffic regulations. Therefore, it is important to create understanding ... -
Empirical Study on Pedestrian Signal Design and Compliance in the State of Qatar
( Springer International Publishing , 2019 , Article)To ensure safe crossing manoeuvres at signalized crosswalks, the pedestrian delays and allocation of sufficient pedestrian green and flashing green times should be considered at design stage. The pedestrian signal settings ... -
Modeling pedestrian crossing speed profiles considering speed change behavior for the safety assessment of signalized intersections
( Elsevier Ltd , 2017 , Article)Pedestrian safety is one of the most challenging issues in road networks. Understanding how pedestrians maneuver across an intersection is the key to applying countermeasures against traffic crashes. It is known that the ... -
Performance evaluation of the inside intersection median-turn lane markings on the mobility and safety performance of signalized intersections in the Philippines and Japan
( Elsevier B.V. , 2018 , Article)Signalized intersections are one of the key elements that play a vital role at road networks. The efficiency and safety levels of intersections can affect the operational performance of the whole system. In general, turning ... -
Speed perception and actual speed in a driving simulator and real-world: A validation study
( Elsevier Ltd , 2019 , Article)Background: Driving simulators have become an effective research tool in traffic safety, but the validity of results obtained in simulated environments remains a debated issue of high importance. Objective: The objective ... -
Studying critical pedestrian behavioral changes for the safety assessment at signalized crosswalks
( Elsevier B.V. , 2017 , Article)Pedestrian-vehicle conflicts are one of the most important safety concerns at signalized intersections especially in urban areas. Conflicting vehicles and pedestrians select their maneuvers by predicting the other user ... -
The effectiveness of applying dynamic lane assignment at all approaches of signalized intersection
( Elsevier Ltd , 2017 , Article)Existing traffic control strategies at signalized intersections aim at the optimization of signal timing parameters while assuming fixed lane assignments to the movements at each approach. Such control results in the waste ... -
The Integration of Dynamic Lane Grouping Technique and Signal Timing Optimization for Improving the Mobility of Isolated Intersections
( Springer Verlag , 2017 , Article)Spatial variations in traffic demand degrade intersection performance that can result in the waste of time�space resources. Existing control strategies of intersections assume fixed lane for movement assignment regardless ...
