Evaluation of Low-Cost Safety Measures on the Hungarian National Road Network

The number of road fatalities decreased by more than 50% between 2001 and 2013 in Hungary. One of the possible reasons was low-cost road safety measures (for instance variable message signs, transversal acoustic as well as durable pavement markings, road studs, shoulder widening and horizontal curve treatments) that were implemented in annual packages from 2007 onwards. This paper analyzes these measures using a comparison group study. Measures were grouped into intersection and section related ones. A sequence of sample odds ratios were used to quantitatively assess the suitability of comparison groups. The expected number of accidents in the after period and finally the crash modification factor (CMF) and its variance were calculated. Using these results a cost-benefit analysis was performed, net present value, benefit cost ratio and the internal rate of return were calculated. The results showed that these low cost safety measures were successful: the crash modification factors ranged from 8% to 35%, with the lowest for geometry treatments at intersections and the highest for dangerous curves in road sections. The cost-benefit analysis showed that low cost measures at intersections as well as on road sections are highly beneficial; their benefit cost ratios are 31.7 and 45.9 respectively.
