| More schools in Mogale City to benefit from road safety project | South African Road Federation (SARF) | Working with our partners, we developed a Road Safety Risk Assessment Model, which includes a Road Safety Risk Index, to prioritise schools where the risk for accidents is high. We made use of the Star Rating for Schools (SR4S) App to measure the road environment, road type, road features, school zone, sidewalks, crossings, flow of vehicles and pedestrians as well as intersections. To measure speed around the schools, we used a hand-held speed gun. Using these tools, we undertook a risk assessment of 50 schools in Mogale City. Those with the highest road safety risk were selected for the project. These included Athlolong primary school, Lengau primary school, Mosupatsela secondary school, Tsholetsega public school, WD Oliphant primary school and Bosele intermediary school. For each school, we looked at a surrounding radius of roughly one kilometre because some children have to cross major roads to get to school. Infrastructure, signage and road markings were also considered. Then, we implemented infrastructure upgrades and speed reduction tactics. These interventions took place alongside road safety education, law enforcement and data management. We also aimed to eliminate hazardous locations and mitigate risk |

| More schools in Mogale City to benefit from road safety project | South African Road Federation (SARF) | Working with our partners, we developed a Road Safety Risk Assessment Model, which includes a Road Safety Risk Index, to prioritise schools where the risk for accidents is high. We made use of the Star Rating for Schools (SR4S) App to measure the road environment, road type, road features, school zone, sidewalks, crossings, flow of vehicles and pedestrians as well as intersections. To measure speed around the schools, we used a hand-held speed gun. Using these tools, we undertook a risk assessment of 50 schools in Mogale City. Those with the highest road safety risk were selected for the project. These included Athlolong primary school, Lengau primary school, Mosupatsela secondary school, Tsholetsega public school, WD Oliphant primary school and Bosele intermediary school. For each school, we looked at a surrounding radius of roughly one kilometre because some children have to cross major roads to get to school. Infrastructure, signage and road markings were also considered. Then, we implemented infrastructure upgrades and speed reduction tactics. These interventions took place alongside road safety education, law enforcement and data management. We also aimed to eliminate hazardous locations and mitigate risk |

| More schools in Mogale City to benefit from road safety project | South African Road Federation (SARF) | Working with our partners, we developed a Road Safety Risk Assessment Model, which includes a Road Safety Risk Index, to prioritise schools where the risk for accidents is high. We made use of the Star Rating for Schools (SR4S) App to measure the road environment, road type, road features, school zone, sidewalks, crossings, flow of vehicles and pedestrians as well as intersections. To measure speed around the schools, we used a hand-held speed gun. Using these tools, we undertook a risk assessment of 50 schools in Mogale City. Those with the highest road safety risk were selected for the project. These included Athlolong primary school, Lengau primary school, Mosupatsela secondary school, Tsholetsega public school, WD Oliphant primary school and Bosele intermediary school. For each school, we looked at a surrounding radius of roughly one kilometre because some children have to cross major roads to get to school. Infrastructure, signage and road markings were also considered. Then, we implemented infrastructure upgrades and speed reduction tactics. These interventions took place alongside road safety education, law enforcement and data management. We also aimed to eliminate hazardous locations and mitigate risk |

| More schools in Mogale City to benefit from road safety project | South African Road Federation (SARF) | Working with our partners, we developed a Road Safety Risk Assessment Model, which includes a Road Safety Risk Index, to prioritise schools where the risk for accidents is high. We made use of the Star Rating for Schools (SR4S) App to measure the road environment, road type, road features, school zone, sidewalks, crossings, flow of vehicles and pedestrians as well as intersections. To measure speed around the schools, we used a hand-held speed gun. Using these tools, we undertook a risk assessment of 50 schools in Mogale City. Those with the highest road safety risk were selected for the project. These included Athlolong primary school, Lengau primary school, Mosupatsela secondary school, Tsholetsega public school, WD Oliphant primary school and Bosele intermediary school. For each school, we looked at a surrounding radius of roughly one kilometre because some children have to cross major roads to get to school. Infrastructure, signage and road markings were also considered. Then, we implemented infrastructure upgrades and speed reduction tactics. These interventions took place alongside road safety education, law enforcement and data management. We also aimed to eliminate hazardous locations and mitigate risk |
