Simple mathematics is behind Transport for NSW's decision to implement a new reduced speed zone of 30 km/h for the Liverpool city centre.
"Pedestrians have a 40 per cent risk of dying in a crash with an impact speed of 40 km/h, but this falls to a 10 per cent risk when the impact speed is 30 km/h," a Transport for NSW spokesperson said.
"We've been working with local councils to identify busy pedestrian locations and we want to provide the community with a safer environment to exercise and move around while ensuring they're able to practise physical distancing."
The changes, which come into effect on July 17, will include new 30 km/h school zones for Liverpool Public School, Liverpool Girls High School, Liverpool Boys High School, All Saints Catholic Primary School and All Saints Catholic College.
Other changes include:
- The existing speed camera on Bigge Street in Liverpool in front of All Saints College will enforce the new 30 km/h speed limit during school zone times.
- Temporary speed humps will also be installed on Bigge Street between Campbell and Elizabeth streets to support the reduced speed zone.
- Special 30 km/h orange school zone signs and road markings will be installed to emphasise the reduced school zone speed limit.
The reduced speed limits are designed to provide a safer environment for residents to walk, cycle and commute.
"We know Liverpool is one of our most walkable cities and we want to continue to keep our community safe as they go about their daily walks, commutes, exercise and general recreation here in the CBD area and around a number of local schools," the spokesperson said.
"As COVID-19 restrictions ease, we are seeing a higher volume of people walking, cycling and exercising in the area.
"To support the increase in activity and improve safety, the existing 50 km/h and 40 km/h speed limits will be reduced as Transport for NSW works to transform Sydney's streets through active transport measures."
Speed cameras within the new reduced speed zones will operate in warning mode for one month from the date of installation during which time drivers caught travelling over the new 30 km/h speed limit will be sent a warning letter to encourage them to change their behaviour. Fines and demerit points will be sent to offending drivers once the warning letter period has finished.
