This project aims to assess the role of headway in crashes in Australia. Short headway or close following in moving traffic is often held responsible for rear end crashes听which account for nearly one-quarter of all crashes (23.5听per cent) in Australia.听
There are rear end crashes at听speeds听as low as 40听km/h that result听in听fatalities. If time headway is less than the reaction and braking time, it could lead to such听crashes.听There听exists a literature gap in understanding the safe distance between consecutive motor vehicles and what scenarios compel drivers to undertake risky听manoeuvres听that lead to rear end crashes and longer-term injuries.听
The primary aims of this research are to systematically review the current state of knowledge about the role of unsafe headway on road safety and to assess close-following or unsafe headways on roads听in听Australia using the Australian Naturalistic Driving Study (ANDS) data.

Knowing the estimated relationship between fatality risk and impact speed more accurately will provide regulators in all countries the capacity of setting safer speed limits particularly for rural undivided (head-on car crashes), divided roads (frontal car into fixed object crashes), and intersection (side impact car crashes). This study could be a reference for speed limit regulation, helping reduce fatality outcomes in road crashes.
