Safety Ranking of Rural Curves Based on Design Consistency

Popis výsledku v původním jazyce

Speeding as a consequence of improper horizontal alignment of rural roads is one of current traffic safety issues on Czech roads. The evaluation of design consistency, i.e. a degree to which a road is designed and constructed to avoid critical driving manoeuvers, has been known as one of the promising tools in this regards. The objective of the presented study is to prove a practical application of this concept on a sample of Czech national road network without its design data. A data collection vehiclewas used to obtain position data on selected roads. The data processing included a determination of horizontal alignment elements and segmentation and a calculation of consistency measures. The calculated speed consistency level allowed safety ranking of curves. These results are subsequently validated with the ranking based on crash frequency. At the end, several practical applications are outlined.
