Effectiveness of 40 km/h speed limits in reducing crashes on Melbourne roads with strip shopping and factors influencing effectiveness
Keywords: Road Environment
Submission Date: 2019
The effectiveness of reducing the speed limit to 40 km/h on Melbourne arterial roads with strip shopping was evaluated in a quasi-experiment. The treatment was associated with a 14% reduction in casualty crashes, 17% reduction in fatal and serious injury crashes, translating to a benefit-cost ratio of 13. Characteristics associated with a larger reduction in casualty crashes were two-lane roads, sheltered parking on both sides, fewer off-street parking facilities, presence of a railway station but without parks or sports fields. FSI crash reductions were larger on roads with fewer off-street parking facilities without a painted chevron median.
