Reactions of the drivers at a signalized intersection with and without a countdown device

摘要

There are many factors influencing on reactions of the drivers at a signalized intersection. One of the factors, that are influencing on driver’s behavior, reactions and decision making abilities are also signalized countdown timers. In the Thesis, we presented the concept of the signalized countdown timers and with measurements justified their influence on drivers. The measurements are not financially evaluated. The measurements were made in a selected intersection in Ljubljana; later the work proceeded in the laboratory. We were observing and measuring start-up lost time and the number of red and ember violations. Based on assumed hypotheses, we came up to a final conclusion, that the presence of the signalized countdown timer is reducing the number of red and ember violations. On the other hand, start-up lost time is at the presence of signalized countdown timer the same, if not grater.
