Multi-Criteria Decision Based Left-turn Signal Control Guideline
There are primarily three types of left-turn controls at signalized intersections, namely permitted, protected, and protected-permitted. Selecting a left-turn signal control type is one of the major elements in traffic signal design and operations, and should be a systematic approach involving …

The A.R.K. Project: A Grassroots, Student-Led, Multiple-Component Intervention to Increase Driver Safety-Belt Use on a University Campus
… use and other safety-related behaviors (i.e., turn-signal use and cell-phone use) were made during pre-intervention, intervention, post-intervention, and follow-up study phases and compared with observations made on drivers in two non-equivalent control groups (VT faculty/staff and Radford …

Community-based feedback to promote road safety
… to test the effects of the feedback on belt use. Turn signal use and right and left hand turn behaviors were also measured to study risk compensation vs. response generalization. Baseline measures were taken for 13 weeks at which point two feedback signs were erected in the community for the …

Driver Safety and Emissions at Different PPLT Indications
… to NCHRP Report 493, there are five major left turn signal indications for permitted operations in the United States. They are: Circular Green (CG), Flashing Circular Red (FCR), Flashing Red Arrow (FRA), Flashing Circular Yellow (FCY) and Flashing Yellow Arrow (FYA). The main goal of this thesis …

Examination of Driver Lane Change Behavior and the Potential Effectiveness of Warning Onset Rules for Lane Change or "Side" Crash Avoidance Systems
… warning onset rules for SCAS were evaluated: turn-signal onset (TSO), minimum separation (MS), line crossing (LC), time-to-line crossing (TLC), and tolerance limit (TL). The effectiveness of each rule was measured by the maximum response time available (tavailable) to avoid a crash for a …

Modeling Slow Lead Vehicle Lane Changing
… of which experimental vehicle is driven. Turn signals are used 64% of the time but some drivers signal after the lane change starts. Of cases in which signals are not used, 70% of them are made with other vehicles nearby. Eyeglance analysis revealed that the forward view, rearview mirror, …
