The State of Qatar and the United Arab Emirates

Abstract

This chapter discusses the principles of road traffic signal control in the State of Qatar and the United Arab Emirate (UAE). In the first section, traffic control standards used in both countries are presented with a focus on the regional differences, the implementation process used, as well as an overview of the currently implemented signal control methods. Section 14.2 discusses the criteria for selection of traffic control strategies used in the two countries and then compares it to the actual implemented strategies. Section 14.3 focuses on the process used to determine the signal timings. Section 14.4 presents the different phasing strategies used, including the typical phasing design used in both countries, the use of transit priority, as well as bicycle and pedestrian treatment. Section 14.5 explains the values and ranges of the parameters used in the timing/phasing design. Section 14.6 discusses special considerations found in the State of Qatar and the UAE. Finally, Section 14.7 presents two examples of traffic signals on intersections in the State of Qatar.
