What is a Redspot?

A Redspot is a location on the road or public transport network with excessive congestion that potentially makes road users 'see red'. Redspots may be an intersection, a length of road, railway crossing, along a bus or tram route or on a walking or bicycle riding path.

How is the 2018 Redspot Survey different to previous surveys?

When RACV launched its first Redspot Survey in 1991, the technology did not exist to measure traffic congestion simultaneously over entire cities, so we asked Victorians to tell us where they thought congestion was worst. Fast forward to 2018 and that technology now exists. By using anonymous data from sensors in vehicles and mobile phone apps, we can pinpoint locations of traffic congestion by road segment and by time of day.

For the 2018 Redspot Survey, we have used real traffic data to narrow down Victoria’s ten most congested segments of road. We are asking you to vote on this list to decide Victoria’s worst Redspot for 2018.

What is congestion?

If there is congestion in a place, the place is extremely crowded and blocked with vehicles or people. Typical symptoms of congestion on our road networks include long queues and delays, and slow moving traffic.

How has RACV measured congestion?

Vehicles travel much slower when roads are congested. RACV has measured congestion on Victoria’s roads by comparing the speed of traffic during congested or peak times, and the speed of traffic during off-peak times during the night ('free flow speed'). The RACV ‘congestion measure’ is the difference between the peak time speed and the free flow speed. The bigger the difference between these two speeds, the worse the congestion. Allowance is made for some locations having lower speed limits in daytime periods.

How does RACV know how fast vehicles are travelling?

Anonymous data from technology in private and commercial vehicles is used. Before the data is supplied by different companies for use, they ‘de-identify’ the data. The change in the position of the vehicle is used to calculate the speed. Depending on the technology in each device, the location is updated as frequently as every second, to a few times per minute. By combining data from many vehicles over a number of months, average speeds can be determined for sections of road.

What will RACV do with my vote from the Top 10 Redspots list?

RACV will analyse the submitted surveys and identify the locations with the most votes. The results will be reported to the public in September 2018 on this website. RACV will forward the findings of the survey to the Victorian Government and Councils, and urge them to allocate adequate funding to address congestion.

What will RACV do with the Redspot I have suggested?

RACV will collate the nominations of congested locations and if a specific location gets enough nominations, we will forward these to the State Government and Councils, and urge them to allocate adequate funding to address the issues.
