An evaluation of five-section protected/permitted left-turn signal displays using advanced driving simulator technology
(2000)One relatively new type of left-turn signal phasing designed to minimize the protected left-turn phase time requirements, while increasing the opportunity for left-turn maneuvers, is protected/permitted left-turn (PPLT) ... -
Human factors considerations in the selection of a uniform protected/permitted left-turn signal display
(1999)This paper provides an in-depth review of the current understanding in the human factors aspects of traffic signal operations, focused primarily on protected/permitted left-turn (PPLT) control and the corresponding PPLT ... -
Traffic characteristics of protected/permitted left-turn signal displays
(2000)At least four variations of the permitted indication in protected/permitted left-turn (PPLT) control have been developed in an attempt to improve the level of driver understanding and safety. These variations replace the ... -
Traffic conflicts associated with protected/permitted left-turn signal displays
(2000)Several different protected/permitted left-turn (PPLT) signal displays are used in the United States, varying in configuration and permitted indication. Questions remain as to the safety implications of using each type ... -
Use of protected/permitted left-turn signal control in the U.S.
(1999)The growing level of traffic demand on urban and rural roadways has led to increased use of protected/permitted left-turn (PPLT) signal control. PPLT signal phasing provides an exclusive phase for left turns as well as a ...
