Our trials identified a number of interesting observations explained in more detail on pages six and seven.  \nStatic  \nsigns  \nSome static signs relating to specific conditions or locations were incorrectly interpreted as though they applied to the main motorway  \nElectronic signs  \n• Electronic speed signs were more challenging for some vehicles  \n• Flashing signs read more reliably than continuous signs  \n• Some sign types, locations and positioning were harder to read than others  \n• Signs within and at the entrance to some tunnels were difficult for vehicles to identify  \nRoadworks  \n• Absence of line markings within roadworks often disengaged lane keeping, for example where temporary‘stick and stomp’ plastic markers were used  \n• Other changes within roadworks also had an impact on lane keeping, such as narrower temporary lanes, road surface changes or markings, and sudden changes with temporary barriers  \nOther objects  \nStopped/merging vehicles were not always detected  \nDigital maps  \nSometimes vehicles incorrectly identified a change in speed limit based on a digital map  \nTunnels  \nLane keeping sometimes disengaged when emerging from a tunnel portal back into daylight  \nLine markings  \n• Passing an emergency bay would sometimes interfere with lane keeping  \n• Lane keeping was sometimes disengaged when line markings changed  \nBends in the road  \nSome vehicles struggled to maintain lane keeping while taking sharper curves in the road (such as at motorway-to-motorway interchanges)  \nExit ramps  \n• Line markings on ramps led vehicles off the motorway  \n• Stationary vehicles at the end of exit ramps were not always detected  \nRoad surfaces  \n• Cracks along the road surface sealed with bitumen often interfered with lane keeping  \n• Markings on the road or changes in road surface material sometimes disengaged lane keeping  \n• Lane keeping was sometimes impacted by changes in light on the road surface  \n2 Queensland Connected and Automated Vehicle trials Stage one-Partially automated vehicles  \n3  \nContents  \nExecutive summary 5  \nFindings and  \nrecommendations snapshot 6  \nCollaboration key to CAV-ready roads 8  \nAbout the trials 9  \nWhat we trialled 9  \nWhat is partial automation? 9  \nHow we ran the trials 11  \nFindings and  \nrecommendations 12  \nLight at the end of the tunnel 12  \nAt a cross road 13  \nEmergency department 14  \nDriven to distraction 15  \nWhat’s the speed limit, again? 17  \nDiscussion 20  \nGlossary 21  \nDisclaimer: The trial findings do not and are not intended to suggest any issues of non-compliance with safety standards of the roads and tunnels.

Today’s roads were mostly designed before the advent of this technology, so we need to assess their suitability for current and emerging vehicles.  \nSince 2017 Transurban has been running trials of partially automated vehicles to understand the infrastructure changes that we may need to make now and over the next few years.  \nOur Queensland trials built on the findings from our previous trials conducted in Melbourne and Sydney during 2017 and 2018, and explored whether these findings applied to the Brisbane motorway network.  \nThese trials used vehicles with partial automation capability, the kinds already on our roads today. This meant that our trials were different from other important pilot activities taking place in Queensland.
