BackgroundSpeed calming interventions have been employed globally as a road safety measure to curb outcomes of RTCs such as injuries and deaths. In Ghana, few studies have reported on the effect of speed calming measures on the severity of road traffic injuries. This study examined the effect of speed humps on the severity of injuries during RTCs on trunk roads passing through towns in Ghana from 2011 to 2020.MethodsThe study employed a quasi-experimental before-and-after study with controls design to answer the research questions. The study used both primary and secondary sources of data. Univariable and multivariable ordered logistic regression was used to examine the effect of speed humps on the severity of injuries during RTCs.ResultsThe mean height, length and spacing of the speed humps were 10.9 cm, 7.67 m and 207.17 m, respectively. Fatal/serious/minor injuries were 35% higher at the intervention than the control settlements prior to installation of speed humps though not significant (adjusted OR (aOR)=1.35, 95% CI 0.85 to 2.14). A significant change in injury severity occurred after the installation of the speed hump devices. There was a reduction of 77% in fatal/serious/minor injuries at the intervention towns compared with the control towns (aOR=0.23, 95% CI 0.11 to 0.47).ConclusionThe findings present evidence suggesting that speed hump is an effective road safety measure in reducing the severity of road traffic injuries on trunk roads.

“…Given the limited success of physical speed countermeasures such as chicanes and speed bumps [ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ], advanced in-vehicle driver assist technologies that can influence travel speed, such as ISA, are expected to bring significant reductions in road trauma [ 30 , 31 , 32 , 33 ] by informing drivers of the posted speed limit for the road they are travelling on. ISA technology commonly uses vehicle-mounted sign recognition cameras and a GPS-linked speed limit database to display the legal speed limit on the dashboard.…”

By being able to communicate the speed limit to drivers using speed sign recognition cameras, Intelligent Speed Assist (ISA) is expected to bring significant road safety gains through increased speed compliance. In the absence of complete digital speed maps and due to limited cellular connectivity throughout Australia, this study estimated the forgone savings of ISA in the event that speed signs are solely relied upon for optimal advisory ISA function. First, speed-related fatalities and serious injuries (FSI) in the Australian states of Victoria, South Australia, and Queensland (2013–2018) were identified, and published effectiveness estimates of ISA were applied to determine the potential benefits of ISA. Subsequently, taking into account speed sign presence across the three states, the forgone savings of ISA were estimated as FSI that would not be prevented due to absent speed signage. Annually, 27–35% of speed-related FSI in each state are unlikely to be prevented by ISA because speed sign infrastructure is absent, equating to economic losses of between AUD 62 and 153 million. Despite a number of assumptions being made regarding ISA fitment and driver acceptance of the technology, conservative estimates suggest that the benefits of speed signs placed consistently across road classes and remoteness levels would far outweigh the costs expected from the absence of speed signs. The development and utilisation of a methodology for estimating the foregone benefits of ISA due to suboptimal road infrastructure constitutes a novel contribution to research. This work provides a means of identifying where infrastructure investments should be targeted to capitalise on benefits offered by advanced driver assist technologies.
