What need in journey time report

CD has been provided with Bluetooth travel time data collected by the Department of Transport and Main Roads on State-controlled corridors throughout Brisbane and surrounds. CD has analysed this data to show fast and slow points on selected corridors.

What need in journey time surveys (PDF)

During May and June 2010, CD conducted a travel time survey along 17 major roads in Brisbane. The aim of this survey was to monitor average travel times and speeds on these routes during the morning and afternoon peak traffic periods, mainly inbound and outbound of Brisbane City.

The results of the 2010 survey were compared to the results of previous travel time surveys conducted by CD in 1993, 1996, 2000, 2004, and 2007 and provide an indication of how major roads in Brisbane are currently performing. 

Red spot (congestion) surveys

The Red Spot Congestion surveys ask members to supply information on congested locations where delays are frustrating, but could be alleviated to some extent. These locations are referred to as 'red spots'.

This report also identifies red spots that road authorities may use to prioritise efficiency improvements on their road networks. It also highlights the need for regular monitoring of major traffic routes in all areas.

Unroadworthy surveys

These reports give details from results compiled in the state-wide CD Unroadworthy Roads Surveys. The surveys asked respondents to supply information on roads perceived to be in a poor or inadequate condition, unfit for the function they are designed to perform and not providing an acceptable level of service to the road user.

Australian Road Assessment Program (AusRAP)

The Australian Road Assessment Program (AusRAP) is a program run by the Australian Automobile Association (AAA) and State and Territory motoring clubs including the CD, dedicated to saving lives through advocating for safer road infrastructure. AusRAP uses two methods of assessment:

  • Risk mapping based on a road’s history of casualty crashes and traffic flow.
  • Star rating maps based on levels of safety built into the road’s design, which can influence the likelihood of a crash occurring and its severity.

Like the successful European Road Assessment Program (EuroRAP), AusRAP represents a valuable tool to explain how roads can change from being safe to unsafe along their length. It also assists road authorities in identifying and prioritising road upgrades.

Risky Roads Project

CD established the Risky Roads project after recognising a void of information concerning missing crash data and prioritisation resources. The resources below present available traffic and crash dataset and prioritisation based on crash history over the entire National network in Queensland, as well as a significant part of the higher order, rural and outer-urban State road network.

The Collective, Individual and Combined Risk maps assess generally high speed sections of the highway network with speed limits of 90 km/h or higher (i.e., crashes are excluded through major townships with lower speeds) - although where there are small towns with lower speed limit located within a single section, these have typically been included.

Risky Roads results

Collective risk shows the density, or total number, of casualty crashes over a given length of road. Collective risk is calculated by dividing the number of casualty crashes per annum by the length of highway.

Individual risk shows the casualty crash rates per vehicle kilometre travelled. This effectively represents the risk of being involved in a crash faced by an individual driver, by taking traffic volumes into account. Individual risk is calculated by dividing the frequency of crashes per annum by the distance travelled on each section of highway per annum.
 
Combined Risk
Both the collective risk and the individual risk reveal important aspects of the safety of a road section. These two risk types have been combined with equal weighting to produce a single risk score per road section (the combined risk score). Once a section of highway has received a combined risk score, it is assigned one of five corresponding colours from Low to High. The cut-off points between colours are determined by ranking sections from worst to least risk across the Queensland roads included in this assessment, calculating the total length of road assessed and then dividing this result into the five colour bandings, each representing as close as possible to 20 per cent of the network assessed. The ‘Combined Risk’ map layer provides clear targets for those roads requiring infrastructure upgrades: governments should focus on roads coloured in red and black as a priority, especially higher volume roads that also have an AusRAP 1 or 2-Star road infrastructure rating.
 
Star Rating for vehicle occupants (smoothed)
Star Ratings are based on the level of safety built into the road, i.e., how safe the road infrastructure is. Sections of road are rated on a scale of 1 to 5-stars, with 1-star being the least safe and 5-star being the safest. Safe roads with design elements such as dual-lane divided carriageways, good line marking and wide lanes have a higher star rating. Lower-rated roads are likely to have single-lanes and be undivided with poor line marking and hazards such as trees, poles and steep embankments close to the edge of the road.
