“…The writing of any report can benefit from using report templates. The checklists were developed in the UK, Australia and New Zealand by their road traffic organisations, the countries where RSA was first implemented (Hirasawa et al, 2005). They play a significant part in RSA and are utilised at various stages during the implementation process.…”

One of the proactive preventive strategies for the global issue of road crashes is the Road Safety Audit (RSA). There are many advantages to using RSA, however, country-specific regulations often apply when it comes to conducting RSAs. The goal of this study was to compare the content of regulations in a sample of seven countries. Crucial indicators were examined and compared. The term ‘RSA’ was defined differently in each set of guidelines. Different project phases in various nations required the RSA methodology. The contents and coverage of the accompanying checklists or forms also varied. The documents unevenly stressed the team’s needs or the auditors’ qualifications. The legal liability issues received no attention from three of the seven guideline publications. The documents of two countries lacked any examples of RSA reports or case studies. The documents of some countries placed a strong focus on certain criteria but fell short in other areas. There was no RSA guideline document which may be referred to as best practice that accounted for the local circumstances and requirements. Improvements to guideline documents are suggested. This study, updated as of October 2023, will assist the road safety community, including transport officials, world banks, highway practitioners, road safety auditors, policymakers, urban planners and research scholars.

“…Many studies to prevent physiological influence and human error by operation monotonicity in human–machine system have been performed so far. However, these methods are based on suppression of monotonous feeling and detection of resulting specific physiological state, such as real‐time detection of sleepiness by physiological indices and suppression of monotonous feeling by providing external stimulation . If the monotonicity of operation bringing the monotonous feeling is regarded as an essential problem, it is required to maintain recognition level during operation.…”

SUMMARY This paper proposes a concept of the adaptive asynchronous human machine system (Async‐HMS) which maintains asynchronous periodic operations against user's actions for avoiding user intention. In order to find the dynamics of the operation period presented by Async‐HMS, discrimination thresholds of the operation period were obtained by psychophysical experiment. According to the thresholds, three levels of fluctuation of the operation period were defined as “constant”, “unrecognizable”, and “recognizable”. Psychophysiological measurement was conducted on the performance of the synchronized key typing task by the three levels of the operation period. A synchronization error as performance index, the hemodynamic parameters as indices of autonomic nervous system's activity, and the amount of the senses as psychological indices were evaluated. As a result, monotonous feeling was eliminated without compromising the performance in case of “unrecognizable” fluctuations in the operation period presented by Async‐HMS.

“…The report stated that the CLRS effects "on mean speed and on speed variance were mixed and made it difficult to draw meaningful and accurate conclusions" [10]. A Japanese report stated, "The average speeds on the section with the rumble strips are almost equal on the section without rumble strips" [5]. This report analyzed multiple speeds and multiple rumble strip depths but did not recommend a minimum speed limit.…”

State-of-the-practice and issues surrounding centerline rumble strips

Centerline rumble strips (CLRSs) are used on two-lane, two-way rural highways for the purpose of reducing cross-over crashes. The state-of-the-practice and issues surrounding CLRSs were reviewed by a literature study, a public opinion survey administered in Utah (533 participants), and a state-of-the-practice survey (41 out of 50 states, Washington DC, and Puerto Rico returned the survey). Installing CLRSs is a low-cost technique for reducing cross-over crashes on two-lane, two-way rural highways. However, the literature review exposed a number of issues associated with CLRSs. The public opinion survey provided statistical evidence supporting the use of CLRSs on two-lane, two-way rural highways. The state-of-the-practice survey compared geometric dimensions of CLRSs with crash data, cost of installation, and maintenance. The survey shows that no geometric standards or highway operating factors have been established for centerline rumble strips. Correlations between the existing installation dimensions and their effectiveness in reducing cross-over accidents, cost of installation, maintenance, and other issues have not been made, indicating the need for clarifying the benefits of CLRSs and minimizing their negative effects.
