Figure 4:        SAFETY RISK SCORE MATRIX




Crash Data

Crash data has been sourced from TMR for the section of Louis Bazzo Drive 500m either side of the
proposed access location for the past five years (April 2016 – March 2021). The data indicates that no
crashes resulting in injury have occurred within the 1km section of Louis Bazzo Drive over the five-year
period, noting that TMR no longer collect data for crashes which only result in property damage.

Risks

Based on our review of the historic crash data on the state-controlled road network, we have identified
the following safety risks associated with the proposal:

        an increase in left-turn traffic volumes may increase the risk of rear end crashes between left-turn
        and through vehicles on the same approach (DCA Code 302)
        an increase in right-turn traffic volumes may increase the risk of rear end crashes between right-
        turn and through vehicles on the same approach (DCA Code 303)
        an increase in right-turn traffic volumes may increase the risk of crashes between right-turn and
        opposing through or left-turn vehicles (DCA Codes 202 and 203)
        an increase in left / right turns out of the site driveway may increase the risk of crashes with through
        traffic (DCA Code 406)

Risk Assessment

The results of the risk assessment are summarised in Table 2. As demonstrated, there are no existing
safety issues and the development is not expected to significantly worsen road safety on the state-
controlled road network. Accordingly, there are no unacceptable existing or development induced safety
risks and no management or mitigation measures have been identified.
