“…In Romania, 60% of road traffic accidents were caused by road alignment (Cioca & Ivascu 2017). This was further corroborated by Cristian and Lucian (2019), who concluded that road design has a significant bearing on road safety. Their study, also done in Romania, revealed that the construction of sidewalks, expanding the number of lanes in certain sections of the road and elevating pedestrian crossings reduced the occurrence of road traffic accidents.…”

Background: Road traffic accidents claim over 1.3 million lives annually around the globe and remain a key socio-economic challenge today. At 20.1 per 100 000, Botswana's fatality rate is higher than the global average of 17.4. Previous studies on the causes of road crashes in Botswana have not explored statistical causality. This study is thus grounded on the theory of causality.Objectives: This study sought to determine the causes of road traffic accidents and fatalities in Botswana. For this purpose, the article discusses the accident count model based on Botswana data. Method:The study used road accident data from 2008 to 2017. Econometric modelling on Gretl was used to compute two ordinary least squares (OLS) regression models. Manual elimination of insignificant variables was performed through the iterations.Results: Both models are statistically significant at p ≤ 0.001, but the accident count model, with an adjusted R 2 value of 0.99 against 0.83, is more robust and has a better predictive power as opposed to the fatalities model. At the individual variable level, the analysis shows mixed results. Conclusion:The study contends that increased exposure and night-time travel increase road crashes, whilst expansion of road infrastructure is inversely related to road accidents. An increase in both population density and exposure leads to increased fatalities. Regulating the importation of used vehicles and investment in rail transport is a potential policy panacea for developing economies. Future studies should investigate the causes of pedestrian fatalities and night accidents.

“…As is true of all road structures, there are the danger of falling accidents due to aging [2]. Traffic infrastructure has been changing to prevent accidents [3]. Road manager do not want to place heavy electrical equipment overhead for driver's safety reasons.…”

We propose multiple aerial imaging system by use of two beam splitters in the optical system of aerial imaging by retro-reflection (AIRR). The AIRR optical system consists of a light source, a beam splitter, and a retro-reflector. Use of two-layered beam splitters enables us to show multiple aerial signs to drivers in multiple driving lanes. The purpose of this paper is to confirm feasibility that an aerial display by use of AIRR for a novel traffic information provision. First, we explain an optical configuration to show aerial images to multiple road lanes, a driving lane and an overtaking lane with AIRR by use of two beam splitters. Next, we have developed a prototype optical system by use of two large beam splitters and a large high-brightness LED sign that is designed to be used for actual road displays. The light source was an LED display with a height of 450 mm and a width of 390 mm, which shows a character. We observed aerial images by naked eyes as experiments. And we discuss the issues for practical application that the experiments have revealed.

“…Road cycling is an endurance sport in which athletes ride their bicycles on courses that mainly contain public roads. The number of vehicles using these public roads is slowly increasing through the years [5] and as a side effect the amount of traffic incidents is also increasing. Safety measures such as traffic calming infrastructure, roundabouts or speed bumps [7,8,11] on public roads are often introduced to cope with this issue and have a significant impact on the number of road fatalities [6].…”

Road cycling is a cycling discipline in which riders ride on public roads. Traffic calming measures are made to make public roads safer for everyday usage for all its users. However, these measures are not always yielding a safer cycling racecourse. In this paper we present a methodology that inspects the safety of roads tailored to road bicycle racing. The automated approach uses computer vision and geospatial analysis to give an indicative racecourse safety score based on collected, calculated and processed multimodal data. The current version of our workflow uses OpenStreetMap (OSM), turn detection and stage type / bunch sprint classification for the geospatial analysis and uses road segmentation and an extensible object detector that is currently trained to detect road cracks and imperfections for visual analysis. These features are used to create a mechanism that penalizes dangerous elements on the route based on the remaining distance and the generated penalties with its relative importance factors. This results in a comprehensive safety score along with a detailed breakdown of the most concerning passages on the course which can be used by race organizers and officials to help them in the iterative process to create an engaging, yet safe course for the riders.
