The State of *** started to use red-light cameras in 2007 at key signalized intersections and the rate of installation has subsequently increased. In 2017, 19.2% of signalized intersections are equipped with red-light cameras. In many cases, the cameras are not installed on all approaches to the intersections. The purpose of this study is to compare the red-light running violations on approaches with and without red-light running enforcement cameras at the same intersections. Actual field observations were used in this study. Different vari- ables were investigated, including the day of the week, time of day, traffic volume, the possibility of glare on an approach, and the lengths of the yellow and all-red times. A regression tree model was used to explain the characteristics associated with the violations. The results showed that the number of violations on low-volume approaches was five times higher than on high-volume approaches. The results also showed that the presence of the cameras significantly lowered red-light running violations. High-volume approaches without cameras had an approximately eight times higher rate of violations than high-vol- ume approaches with cameras. The analysis also showed that bringing the all-red interval closer to the values recommended by the Institute of Transportation Engineers formula may bring down the rates of violations for low-volume approaches. As with any observational data mining method, the study could benefit from a larger sample size. The method used in the study was effective and is easily transferable to other locations. The results of this study can be used in developing new strategies to improve safety at signalized intersections.

While Pinter's earliest plays have been recognized in the modernist history of theatre as comedies of menace and his later plays as political comedies,this article argues that his earliest plays are equally very liable to be interpreted as political *** of their absurdist dramatization of people's helpless exposure to external,unidentifiable threats,a common post-WWII characteristic feature of human experience,I claim that The Room and The Dumb Waiter(both written 1957,staged 1960),two model examples of Pinter's earliest oeuvres,do not simply follow the aesthetic of absurdist theatre to express human *** audience's experience of viewing the theatrical performances of both plays in terms of discursive cyclicality or character normality is subverted into one of changeability,strangeness,and *** foreground the political implications of such revolutionary theatrical experience,Pinter's plays are examined in the light of his unique use of defamiliarization,relying not on Brecht's traditional techniques of singing,dancing,image-projecting,or captioning,but on a simple,dual technique of image destruction and *** consists of divesting characters of their normality and portraying them instead as individuals who identify only with unusual images of place,time,body,and *** this special technique of defamiliarization,both plays are examined to reveal Pinter's central political theme of undermining reality for purposes of mental and physical subjections.

The Toarcian Marrat Formation is exposed in outcrops in central Saudi Arabia and displays a variety of clastic and carbonate facies associated with well-preserved depositional geometries. It is unconformably overlies the Triassic Minjur Formation and it in turn is overlaid by the Middle Jurassic Dhruma Formation. Thirteen lithofacies types can be identified that permit the recognition of five lithofacies associations in a mixed clastic/carbonate platform. These lithofacies range from low-energy peritidal, intertidal, and back-shoal to moderate-and high-energy shoal and foreshoal lithofacies associations. The Marrat Formation exhibits three depositional sequences, each sequence is grouped into a transgressive systems tract(TST) and a highstand systems tract(HST) and then bounded by sequence boundary surfaces(SBSs). The TSTs are generally identified in clastic tidal-flat beds and back-shoal wackestones, while the HST is generally recorded in the carbonate tidal-flat and shoal. The vertical succession of facies associations from peritidal to foreshoal depositional environments is indicative of a deepening upward and retrogradational systems tract, from Lower to Upper Toarcian. The correlation between the studied sections reveals a general shallowing towards the south and the similarities between the studied sequences and others in the Arabian Gulf, the northern Neo-Tethys Plate, and Gondwanaland countries.
