Break down of CISs vehicles 28 30 Cars Taxis 300 School Buses
Conclusion CIS’s Private Cars
What is the Scale ofCongestion on Braemar Hillin terms of Spatial Context and Time?
Scale of Congestion• Scale of congestion worsens as time progresses• The area of congested road increases
Map 3: The map above shows the congested areas on Braemar Hill during the investigation
Map 4: The map above shows the data collection points during the investigation
0:20:10 Total Traveling Time from 0m to CIS 0:17:17Length of Travel time over 1100m 0:14:24 0:11:31 0:08:38 0:05:46 0:02:53 0:00:00 7:04:48 7:12:00 7:19:12 7:26:24 7:33:36 7:40:48 7:48:00 7:55:12 8:02:24 Car Arrival Time at 0m
Conclusion During peak hours, the congestion spreads: ½ way down Cloud View road, ¾ the way down Tin Hau Temple road, 3/5 the way down Pak Fuk road. Traveling time is multiplied 13 times during peak hours
How are We Affected by the Traffic Congestion on Braemar Hill?
