“…Our finding that installing HSR on freeways leads to increases in crashes is consistent with previous studies from the USA [48,49] and Austria [50], but in contrast with the results obtained in another study from the USA [19], two studies from Germany [51,52], a study from the United Kingdom [53], and one from France [23]. some of the differences in the results obtained may be attributed to differences in the driving culture between countries, while some of the differences may be due to the methods used to evaluate the safety impact.…”

“…some of the differences in the results obtained may be attributed to differences in the driving culture between countries, while some of the differences may be due to the methods used to evaluate the safety impact. Most of the studies did not perform any before-after analysis, except one [23] that also used an empirical Bayes method.…”

“…The aim of this study is to evaluate the safety effect of HSR by applying the EB (empirical Bayes) methodology to crash data from South Korea collected before and after the HSR trials. More The authors' review of the literature suggests that the international evidence on HSR is mixed [9][10][11][12][18][19][20][22][23][24]. More importantly, conflicting results and views have yet to be reconciled [19,20,24].…”

Hard shoulder running (HSR) has been increasingly used as a sustainable and viable way to increase road capacity. This study investigated the safety effect of HSR on freeways in South Korea using the empirical Bayes method. This study found an increase in the total number of crashes. In terms of crash severity, a higher proportion of crashes (25.3%) on 2(3)-lane sections were found to be serious (involving injuries and/or fatalities) compared to those on 4(5)-lane sections (3.6%). Also, a positive relationship was found between the length of the hard shoulder running and changes in crash frequencies. Thus, hard shoulder running on lengthy 2(3)-lane freeways should be avoided.

In fact, socioeconomic, population, motorization level and road safety experiences are vary from region to region.…”

Road accidents as a global challenge, imposing irreparable financial and human life losses in almost all countries, especially in developing countries, annually. According to world health organization (WHO), if this trend continues, road accidents will become the 7th cause of human death by 2030. Thus, road safety policy makers have been trying to use safety promotion and preventative actions. In this paper, the road safety performance of Iranian provinces is studied. To evaluate road safety efficiency scores, data envelopment analysis based on road safety (DEA-RS) method in two deterministic and non-deterministic situations is used. To consider the uncertainty in input and output data, this paper develops credibility DEARS (CreDEA-RS) model. In fact, the constraints of DEARS model are considered as credibility constraints and a counterpart credibility DEARS (CreDEA-RS) model is proposed for evaluating road safety of provinces of Iran. According to the results, provinces located in mountainous and forest areas such as Gilan had a much weaker performance than provinces in desert areas such as Yazd. .

“…However, there appears to be no significant difference beneath this traffic volume; this can be attributed to the dispersion of speeds under free flow at a rather random manner and does not affect severity in a consistent pattern. We note that in previous work by Aron et al (2009) in accident frequency estimation, the authors concluded that under 'fluid' traffic conditions only 29% of the accidents occur, while fewer injury accidents occur in 'dense' traffic.…”
