The most successful treatment for a rural bend is shown in Figure 6.6, it produced a reduction in mean speed at curve entry of 3.4 km/h as compared with no treatment. The countdown signs that were the most effective treatment for the approach to village entry, with a speed reduction of 4.7 km/h as compared with no treatment, are shown in Figure 6.7. The most effective solution for rural straight sections was very similar to the 2-1 concept. These speed reductions are highly significant in safety terms. However, a real-world evaluation to substantiate that the selected treatments worked in the real word has not so far been earned out.
