Pedestrian Casualties remain a focus

In 2010, pedestrian fatalities and serious casualties are 69 (59%) 和

816 (38%)

During the decade 2001 to 2010, 871 pedestrians were killed and

9,782 were seriously injured

In 2010, urban minor streets and major streets accounted for 40%

and 50% of fatalities Trend of Pedestrian Fatalities 2001-2010 2011 figure is similar to 2010

Traffic Calming in the Urban and Rural Context

To reduce speed to a level commensurate with the

activities along the road

Facilitate walking and cycling
Enhance the environment, aesthetic and identity of

neighbourhoods

Visibility and Railings

Average height of 6 year old child in Hong

Kong : 1176mm (So et. Al, BMC Public Health. 2008; 8: 320)

Standard height of pedestrian railing : 1000mm

Visibility at Pedestrian Crossings

Drivers should be able to observe the intention of

pedestrians both on the crossing and over the waiting area of the footpath

An Ever-growing Low speed Culture

Barcelona： 215 km 30km/h streets
Brussels : entire old city 30km/h except main

streets

Munich ：> 300 30km/h zones (85% city road

length)

London : > 400 20mph zones

Traffic Calming Design within Communities

Speed limit sign/special markings
Street redesign/Narrowing lanes
Trend of subtle design to weaken the perception of

a highway e.g. no centreline markings

Conclusion

Area-wide traffic calming with lower

speed limit will be the key of an ambitious road safety strategy in Hong Kong Kong

Lower speed limit on urban streets is

also the key to an attractive and vibrant streetscape conducive to the economy and living quality
