| Abstract | 16 High-speed signalized intersections are associated with vehicle crashes due to dilemma zone 17 problems. Dilemma zones (DZ) are areas where, at the onset of yellow, some drivers may decide 18 to proceed, and some may decide to stop. This disagreement among drivers can lead to rear-end 19 crashes and/or right-angle crashes. The research objectives of this work was to conduct a field 20 comparison of a radar-based dilemma zone protection system using high-resolution data. 21 Namely, we aimed to compare the frequency of red light runners (RLR) and percent arrivals in 22 green (POG). In addition, it was also desired to shed more light into the value of using high23 resolution data in such comparison, and how much data is needed. 24 Researchers found that one week of high-resolution data is sufficient to draw conclusions 25 on the effectiveness of radar-based DZ protection system. A before-and-after comparison of red 26 light running frequency indicated an up to 80 percent reduction in red light runners when a radar27 based DZ protection system was used. 28 29 |
