Abstract
Roadside type is a crucial factor that affects road safety. This study aims to investigate the impact of 15 roadside types using the international Road Assessment Program (iRAP) model, which utilises the star rating system as a measure of road safety. The study, uniquely, focuses on using risk assessment models to evaluate the impact of roadside types on road safety in the case of a lack of crash data. The required geometric and traffic data were collected for two sections of the Army Canal highway in Baghdad city. The results showed that one roadside type (wire rope) improved safety performance, while others led to a reduction or limited effect on safety levels compared to the existing metal barriers in each section. It was observed that this option lowers the Star Rating Score (SRS) for section 1, driver side and passenger side, from 12.71 to 11.58 and from 12.62 to 11.42, respectively, corresponding to an 8.9% and 9.5% reduction in risk score, which was sufficient to shift the road section from Star Rating 2 to Star Rating 3. The study revealed similar results for section 2 with a different SRS.
In Addis Ababa, Ethiopia, pedestrians account for more than 80 percent of all fatal crashes. Speed humps have been implemented citywide since the launch of a road safety strategy in 2017 to calm vehicular traffic and improve road safety. The city targeted major roads and installed over 550 round-top asphalt concrete sp...

Road safety is a fundamental component of sustainable urban mobility, requiring transportation systems that support safe, efficient, and evidence-based territorial planning. Although traffic safety is commonly evaluated using individual indicators, their isolated application often limits comprehensive territorial asses...
Roadside trees represent the most frequently struck fixed object in fatal crashes in the United States and constitute a substantial safety concern, particularly on high-speed rural roadways. Although trees are often retained or planted along roadways for aesthetic and environmental benefits, their presence within the r...

Saudi Arabia’s rural highway network experiences a high number of severe run-off-road and rollover crashes, yet evidence-based, locally validated roadside clear-zone design guidance remains limited. This study investigates how roadside clear-zone characteristics influence the occurrence and severity of these crashes by...

Background. Global road traffic fatalities continue to rise, posing significant public health and economic burdens, with estimated productivity losses of $12.69 billion, equivalent to 4.1% of GDP. Developing countries are disproportionately affected, highlighting persistent disparities in road traffic deaths. In the Ph...
Road traffic accidents with large number of fatalities are recorded in Nepal, a country with challenging topography, combined with inadequate road design, poor maintenance, and lack of safety measures. Conventional approach for identifying hazardous location based on historic data is unreliable due to underreporting an...
