The crash data for 2014 to 2018 inclusive shows the fifteen traffic intersections with the highest reports of vehicle accidents in the City of Cockburn. They are ranked according to the number of people injured, the frequency of accidents and the cost of injury and damage. The road improvements are funded under the state and federal Black Spot Programs to provide a safer road network for drivers, motorcycle riders, pedestrians and cyclists.
For the five-year period to the end of 2018, the top 15 black spot intersections in the City of Cockburn were:
Stock Road and Phoenix Road Armadale Road and Tapper Road
101 crashes (20 casualties), crash cost $4.01M for five years
Stock Road is a State road. Mainly rear-end/side-swipe crashes (81 out of 101 crashes). High number of rear-end crashes turning left from Phoenix Road (westbound) into Stock Road (southbound). Monitoring.
86 crashes (17 casualties), crash cost $3.5M for five yearsArmadale Road and Solomon Road
Armadale Road is a State road. Predominantly rear-end type crashes, although annual crash rate is decreasing. This intersection will be upgraded by Main Roads WA between 2019 tand 2021 as part of the Armadale Road Bridge project. A 'duck and dive' intersection and additional traffic lanes are proposed.
80 crashes (17 casualties), crash cost $4.16M for five yearsKwinana Freeway South, Russell Road and Gibbs Road
Armadale Road is a State road. Predominantly right-angle and right-turn through type crashes, although annual crash rate is decreasing. This intersection will be upgraded by Main Roads WA between 2019 and 2021 as part of the Armadale Road Bridge project.
58 crashes (15 casualties), crash cost $2.46M for five yearsHammond Road and Beeliar Drive
Kwinana Freeway interchange is a State road. Intersection upgraded in 2017 as part of the Russell Road/Gibbs Road works by Main Roads WA. Predominant crash type is rear-end/side-swipe type crashes which are significantly over-represented. Intersection upgrade should result in annual crashes reducing.
60 crashes (13 casualties), crash cost $2.46M for five yearsNorth Lake Road and Farrington Road
The staggered T-intersections at this location were realigned in early 2015 to form one four-way intersection with traffic lights. As a result, the crash rate dropped from an average of 17.2 crashes a year over five years to 12 crashes in 2018.
65 crashes (13 casualties), crash cost $2.45M for five yearsCockburn Road and Russell Road (West)
Annual crash numbers have reduced slightly in recent years. Predominantly a rear-end crash problem. Significant demand for right-turn from North Lake Road into Farrington Street results in a safety hazard because demand regularly exceeds turn lane capacity during peak hours. Submitting for black spot funding 2020/2021.
76 crashes (13 casualties), crash cost $2.6M for five yearsPhoenix Road and Rockingham Road
Cockburn Road and Russell Road are both State roads. Main Roads WA are developing a project to upgrade this intersection which is currently at concept stage. City to monitor.
58 crashes (11 casualties), crash cost $3.4M for five yearsStock Road and Spearwood Avenue
Proposed as part of upgrade to Rockingham Road. Safety could be improved by providing separate signal phases for each leg of the intersection or a roundabout. Predominant crash types are right-angle and right turn thru crashes and rear-end crashes. Difficult intersection to improve because of land and infrastructure constraints. Submitting for black spot funding 2020/2021.
86 crashes (11 casualties), crash cost $3.65M for five yearsPhoenix Road and North Lake Road
Stock Road is a State road. The City has asked MRWA to upgrade signals and improve pedestrian crossing. City to monitor.
50 crashes (10 casualties), crash cost $2.35M for five yearsArmadale Road and Warton Road
Intersection upgraded in 2019 with double right turn heading south, right turn pocket heading west and left turn pocket heading north west were extended. City to monitor.
37 crashes (10 casualties), crash cost $1.51M for five yearsMidgegooroo Avenue and Beeliar Drive
Armadale Road is a State road and this is part of the current Armadale Road duplication project. Traffic signals installed by Main Roads WA in early 2014 and crashes have reduced since. Monitor.
116 crashes (10 casualties), crash cost $4.5M for five yearsKwinana Freeway and Berrigan Drive
Signalised intersection upgraded by Perron Group to support Gateways Shopping Centre expansion. Predominantly rear-end/side-swipe type crashes. In 2015 this intersection was the highest ranked intersection in Cockburn by crash frequency - 158 crashes from 2010-2014 inclusive. Crashes reducing.
Monitor, review intersection safety and performance as part of any further expansion of the Perron Group Gateways Shopping Centre expansion and proposed overpass for pedestrians. City to review intersection safety and performance before any further expansion of the shopping centre is approved. Area should benefit from Armadale Road upgrade and the new Armadale Road Bridge.
41 crashes (10 casualties), crash cost $1.52M for five yearsCockburn Road, Hampton Road and Rockingham Road
Kwinana Freeway is a State road. Part of the State project for Main Roads WA – Freeway North Widening.
35 crashes (9 casualties), crash cost $1.74M for five yearsSpearwood Avenue and Beeliar Drive
Main Road WA intersection. Concept plan developed for proposed upgrade of cycling infrastructure and median islands along Rockingham Road. Monitoring.
66 crashes (9 casualties), crash cost $3.48M for five years
Spearwood Avenue was widened to a four lane divided road in 2019. The City has a project concept plan in place. Monitoring.
The District Traffic Study 2018 provides the foundation for future road network planning of the City of Cockburn. It does this in terms of setting road network upgrade priorities and providing a framework for ongoing analysis of the road network.
