Q$3.$ Identify one $(1)$ real case study involving motorcycle, scooter or moped safety issues related to road infrastructure. The case may involve a known hazardous road segment, an accident$-$prone corridor or an area that implements recent safety improvements targeting two$-$wheeled vehicles. Using the selected case study, answer the following questions.

$($a$)$ Investigate the geometric design, traffic control systems and traffic operational features of the road on your chosen case study. Discuss the contribution of these elements to the safety risks for motorcycle, scooter or moped riders.

$(10$ marks$)$

$($b$)$ Analyze a safety audit framework that could be applied to the selected road segment to assess and monitor risk for two$-$wheeled vehicle users. Include at least four $(4)$ specific audit parameters relevant to safety engineering.

$(10$ marks$)$

$($c$)$ Identify three $(3)$ specific and justified safety engineering interventions or traffic operational strategies that could improve conditions for motorcycle, scooter and moped riders on the selected case study.
