Optimization of Traffic Safety for Motorists with Raised Intersection Design at Intersection in DKI Jakarta

Urbanization trends, coupled with the proliferation of motor vehicles, have led to escalating environmental challenges like congestion and pollution. Sustainable transportation systems are increasingly imperative to address these issues, necessitating pedestrian-friendly urban environments to promote sustainable mobility. However, escalating traffic density poses serious safety concerns for pedestrians, exacerbated by improper use of pedestrian facilities. Statistical data underscores the vulnerability of pedestrians, with a notable percentage of traffic fatalities attributed to pedestrian accidents. To mitigate these risks, enhancing pedestrian safety through various measures, including raised crosswalks, has garnered attention. Raised crosswalks offer promising potential to improve pedestrian safety by influencing driver behavior and enhancing pedestrian visibility. This research aims to explore the impact of raised crosswalks on traffic safety in Indonesian urban environments. Through quantitative analysis and video observation, the study evaluates the effectiveness of raised crosswalks in enhancing safety and traffic compliance at intersections. The findings reveal varying severity levels of near-miss accidents, suggesting targeted risk mitigation strategies. Regression analysis indicates a substantial reduction in vehicle speed post-implementation, although other influencing factors persist. Moreover, Cost-Benefit Analysis underscores the financial viability of pedestrian crossing enhancements, emphasizing the potential for significant gains. Ultimately, this research contributes empirical insights to inform policy formulation and infrastructure design, facilitating safer and more sustainable pedestrian environments in Indonesian urban areas.
