Greater Brisbane key corridors

Network vehicle kilometres travelled summary

Average vehicle kilometres travelled of 37 key corridors by month

Traffic volume and vehicle kilometres travelled

All traffic volume data includes weekdays only and excludes public holidays. Traffic volumes on TMR corridors were taken at the road segment with the highest volume. Council corridor traffic volumes were taken in the middle segment of the corridors.

The average daily traffic volume for the month is the number of vehicles utilising the corridor per day, averaged over all weekdays of the month (excluding public holidays).

AM peak period for TMR corridors is from 6am to 9am as the TMR network is utilised earlier particularly on the outer edges of the Greater Brisbane road network (for example, Bruce Highway, Pacific Motorway and so on). Council corridors’ AM peak period is from 7am to 9am. PM peak periods are the same for both TMR and Council corridors, 4pm to 7pm. The monthly AM and PM peak per hour traffic volumes are the average hourly volume for the month over the corresponding AM and PM peak periods, respectively.

Vehicle kilometres travelled (VKT) is a measure of traffic demand on the road network. It is the length of a section of road in kilometres multiplied by the average traffic volume on that section. The daily VKT is the product of the length of the road and average daily traffic (ADT). The monthly VKT is the daily VKT multiplied by the number of days in the analysis period.

The AM peak monthly VKT is the product of the length of the road, the average AM peak hourly traffic volume and number of days in the analysis period.

The PM peak monthly VKT is the product of the length of the road, the average PM peak hourly traffic volume and number of days in the analysis period.

The network VKT is the sum of all the corridors in the network.

Average network speed summary

Average speed of 37 key corridors

Average speed

Average speed in kilometres per hour is a measure of traffic efficiency on the road network. Average speed was calculated using travel times collected from TMR’s and Council’s extensive network of Bluetooth scanners within the Greater Brisbane road network. Average corridor speed includes delays at signalised intersections.

Average travel times were collected during the AM and PM peak periods to calculate the average speed of the corridor. Peak periods are similarly defined as in the VKT calculations.

AM peak travel time is taken as the inbound direction while the PM peak travel time is the outbound direction.

Kingsford Smith Drive: Case study

Historically, Kingsford Smith Drive (KSD) is one of the most significant routes in the city for Brisbane’s economic prosperity.

A major road corridor, KSD links the Brisbane CBD to Brisbane Airport, the Port of Brisbane and residential and economic growth areas including Northshore Hamilton and the Australia TradeCoast (ATC). The ATC is expected to be the second biggest job generator in South East Queensland, behind Brisbane’s CBD, in future years.

Traffic volume trend

The graph shows the average annual weekday traffic volume on KSD for the past eight years. KSD volume decreased significantly with the opening of the Airport Link (APL) tunnel in July 2012. Since then however, traffic volume has been increasing rapidly (one of the highest of the key corridors) and has surpassed pre-APL volumes.

""

Average speed trend

From 2012, average corridor speeds have slowly decreased for the AM and PM peaks. With the continued economic growth of areas serviced by KSD, the average speed will likely continue to decrease.

By 2030, Northshore Hamilton alone will be home to around 15,000 people and will be a hub of employment for up to 10,000 people in commercial and retail businesses. Together with ATC, this is expected to generate approximately 30,000 extra vehicle trips per day.

The KSD upgrade is the next flagship project to be delivered by Council to transform Brisbane’s road network. The upgrade serves as a key part of Council’s balanced approach to tackling traffic congestion in Brisbane, which could cost businesses and residents up to $3 billion by 2020, if not addressed.

Bruce Highway Managed Motorways Project (BHMMP)

The Bruce Highway Managed Motorways Project involves a suite of smart technologies on the Bruce Highway southbound between Caboolture and the Gateway Motorway to optimise the performance of the highway and maximise its existing capacity during peak periods. Ramp signals and electronic communications technology have been installed at five onramps to the Bruce Highway southbound at Dohles Rocks Road, Anzac Avenue, Boundary Road, Deception Bay Road and Uhlmann Road. Installation of the ramp signals and electronic communications technology began in April 2014 and was completed in September 2015, with the system starting operation in September 2015.

The project aims to deliver the following benefits to motorists:

  • managing traffic flow onto the highway at key congestion points to help keep traffic flowing on the highway and delay the onset of congestion
  • providing safer merging conditions for motorists entering the highway
  • reducing ‘stop-start’ travel for motorists and helping to improve travel time reliability
  • optimising the performance of the Bruce Highway and maximising its existing capacity until future upgrades can take place
  • allowing a proactive and responsive approach to managing network conditions and responding to congestion, incidents or bad weather.

Kingsford Smith Drive (KSD) upgrade

As a major gateway to the city for tourists, visitors and residents, KSD will be transformed into a vibrant urban corridor that maximises public access to the river and reinforces Brisbane’s identity as a New World City.

The KSD upgrade will create a subtropical arrival experience into Brisbane, providing shade and enhancing views of our river city.

Trees will be planted along the entire corridor, with centre median planting creating a memorable journey for all road users while maintaining views for local residents.

The KSD upgrade will involve widening the road from four to six lanes between Theodore Street at Eagle Farm and Cooksley Street at Hamilton. It will also include improvement works between Cooksley Street and Breakfast Creek Road at Albion.

In addition to providing increased road capacity to accommodate future traffic volumes, the upgrade will also deliver significantly improved pedestrian and cycle facilities, providing active transport options for both existing residents and the developing Northshore precinct.

Council selected Lendlease as the preferred contractor to design and construct the KSD upgrade.

Inner City Bypass upgrade

Council is planning to widen the Inner City Bypass (ICB) between Legacy Way and the Royal National Agricultural (RNA) tunnel to increase capacity and allow for future growth along the key corridor.

The ICB 4 upgrade will see the ICB southbound widened from three to four lanes between the northern approach to the RNA tunnel and the Legacy Way portal, and the ICB northbound widened from three to four lanes between Legacy Way and the ICB Herston exit.

The upgrade will reduce traffic congestion and increase capacity for existing and future traffic demands. This section of the ICB currently carries more than 100,000 vehicles per day and is a major link in the road network with connections to Lutwyche Road, Airport Link Tunnel, Clem Jones Tunnel, Legacy Way Tunnel and the soon-to-be-upgraded KSD.

$80 million will be allocated over the next three years for the project and a contract tender process is planned to occur during the next year.

As part of the preliminary design, Council will be undertaking a technical investigation to determine if a new westbound on-ramp from Bowen Bridge Road/Inner Northern Busway is feasible. This is expected to be completed in early 2016.

Construction is tentatively scheduled to begin in late 2016 and be completed in 2018.

Wynnum Road corridor upgrade – stage 1

The Wynnum Road corridor is an important route in Brisbane’s road network, providing access between suburban and commercial catchments in the eastern suburbs of Brisbane, the CBD and beyond.

Council is planning to deliver the upgrade to the Wynnum Road corridor in stages. Stage 1 of the upgrade is from Latrobe Street to Canning Bridge and will see this section of Lytton Road widened from four to six lanes.

Roads and intersection upgrades

Council is building an improved road and transport network across Brisbane through a range of key projects including major road construction and intersection upgrades. To improve access to major transport networks, Council is also working to minimise traffic congestion and improve safety in local areas by constructing intersections, and undertaking corridor upgrades and minor road projects.

Upgrades under this program are part of Council’s $49 million commitment in 2015-16 for suburban road and intersection upgrade projects. This program is part of Council’s commitment to keep Brisbane moving, and is jointly funded by the Queensland Government under the Transport Infrastructure Development Scheme.

Road resurfacing program

Our roads are one of our most critical assets, which is why Council continues to prioritise their maintenance. Council’s 2015-16 road resurfacing program will help make suburban streets smoother, safer and more enjoyable to use every day, representing a $100 million investment. Works will occur across every Council ward and will deliver an unprecedented number of resurfacing projects for Council within this period of time.

This $100 million investment for the 2015-16 financial year will build on Council’s commitment of $240 million of road resurfacing works over four years to ensure Brisbane’s transport network continues to deliver a high-quality experience for users.

Factors affecting network performance

Significant incident data

Traffic volume and travel time are also affected by other factors including traffic incidents. These incidents, such as accidents, extreme weather and planned events, influence the amount of congestion experienced on the roads. Depending on the timing, location, severity and duration, an incident may have minimal effect on the road network or cause gridlock in large parts of the city. The data detailed in this report specifically analysed significant incidents that had the potential to have a major impact on the road network.

This incident data was collected and compiled from roads throughout the Brisbane metropolitan area by the Brisbane Metropolitan Transport Management Centre (BMTMC).
