Year 12 Geography Study - Braemar Hill Congestion

C
Chinese International School

This document analyzes traffic congestion on Braemar Hill in the mornings. Maps and timelines show that congestion starts around 7:15 AM and spreads as more vehicles arrive, blocking over half the roads by 7:50 AM. The investigation found private cars dropping off students at Chinese International School were the primary cause. Travel times increased up to 13 times during peak hours. Interviews found the congestion negatively impacted commute speeds, increased noise levels that could damage hearing, and raised health concerns due to vehicle emissions. In conclusion, the CIS private cars were causing major traffic issues that affected the surrounding community.
