Moving transport from announcements to measured improvements Until now, Australia has measured transport inputs such as dollars spent, lanes added and the like however we have not measured how the road network actually works, for people and businesses. The IPA Australian Travel Time Metric uses Uber s anonymised journey data to index road transport performance, across each of the four major capital cities. The IPA Australian Travel Time Metric measures the progress of Australia s major cities in addressing their transport challenges and provides greater public transparency about how much longer trips are taking over time. The IPA Travel Time Index is a live resource available at infrastructure.org.au/chart-group/travel-time-index-chart/ Average travel delays the time in minutes that people spend in traffic are also measured across key zones and corridors, in the four major capital cities. 2 Australian Travel Time Metric 217 Edition

Key Corridors Marking time & Methodology Marking time: minutes of delay IPA s Travel Time Index provides an important measurement of comparative performance between the major cities showing which cities are doing comparatively better and those doing comparatively worse. But an index alone is unlikely to fire the public imagination, nor help people to best understand the personal cost that comes from poor transport. That is why we also measure and report the average delay in minutes along key corridors, zones and routes within each city showing people the amount of extra time drivers sat stationary in their vehicle, this quarter and each quarter, since 2. Data for every quarter from Q3 2 onwards is available on the IPA website under the Travel Time Index in the utilise our data section. Methodology We measure the average time delay for journeys between CBD, inner suburban and outer suburban zones shown in Figure 2 below. We have also identified relatable corridors within each city from key geographies or between nodes, for example, between the CBD and each city s airport. We calculate the average time delay simply by measuring the difference between the average time for an off-peak journey, versus one made during the (inbound) or (outbound) peak times. We do this because a delay in minutes is much more relatable than more esoteric measures like our index or the various estimates of economic and social congestion costs.

Analysis While Sydney s index performance is equal worst with Brisbane, the location of major changes like along the CBD Parramatta corridor (see Figures 6 and 7) shows that Sydney s road system is suffering delays in part because of the massive level of transport infrastructure delivery now underway, with major projects such as WestConnex and CBD and South East Light Rail. Future versions of IPA s Australian Travel Time Metric should show a corresponding improvement, as these projects open. However, increases in delays cannot all be attributed to construction programmes, as seen with the deterioration in travel times on the CBD Airport corridor, which increased from Q3 2 by 2. minutes on inbound trips to the CBD (see Figure 4). Travel time on this journey is 84 per cent longer during peak hours the largest per cent change on any route in the IPA Australian Travel Time Metric. The two zones also saw deterioration in journey times for commuters in Inner and Outer Metro areas. The largest was for Outer Metro commuters travelling into the CBD at peak who saw delays increase by 2.1 minutes from Q3 2, reaching 1.9 minutes in Q2 217 a 24 per cent increase. Unlike corridors, the zones capture a ring, equal in diameter, around the CBD and represent broad changes in travel time for commuters. Australian Travel Time Metric 217 Edition 7

Analysis Melbourne s change in travel times across the CBD Airport and CBD Chadstone corridors appear substantial compared to Sydney, Brisbane and Perth. For the CBD Airport route, the inbound commute saw a reduction in travel delay, however this is due to swings in both peak and off-peak travel times on the corridor (see Figure 9). It can be seen that off-peak travel times have grown steadily since the Australian Travel Time Metric began in Q3 2 a time which coincides with the commencement of construction on the CityLink Tulla Widening project the connecting arterial motorway along this route. Peak travel times also grew during this period, which culminated in a peak delay over Q3 216 of 17.3 minutes on inbound peak trips, and a 17.6 minute delay on outbound peak trips. Since then, peak journey times have begun to reduce to levels that approach off-peak times, therefore reducing the overall delay. In fact the largest increase in off-peak and peak travel time across all cities key routes was the Airport to Melbourne CBD corridor. Conversely, Melbourne CBD to Chadstone saw the largest improvement of any corridor in the country with peak travel times falling from 27.6 minutes in Q3 2 to 19 minutes in Q2 217 a 3 per cent decrease (see Figure 12). However, this route also showed the greatest volatility in peak travel time across all cities. Over the reporting period, average peak travel times ranged from 27.6 to 19 minutes, each quarter, while off-peak travel times only ranged between 14.7 and 17.8 minutes. This has resulted in some fluctuation in travel delay times, which reached a peak of 12.9 minutes over Q3 2, and as low as 3.4 minutes in the most recent reporting quarter Q2 217.

Analysis Travel delays across Brisbane s key routes have mostly increased over the reporting period to Q2 217, with rises of up to one minute across key routes compared to Q3 2. The Inner Metro inbound route travel delay reached above five minutes for the first time in Q1 217 and sits at five minutes in Q2 217 (see Figure 13). This route also experienced the longest delay for Brisbane over Q2 217 as a percentage of total travel time which was 4 per cent longer compared to off-peak travel. Notably, peak and off-peak travel times increased slightly on both inbound and outbound travel on the CBD Airport Corridor (see Figures 14 and ). However, overall delays have been much higher on inward bound journeys (seven minute average over the reporting period) compared to outbound delays (3.4 minute average over the reporting period). This suggests last mile entry into the Brisbane CBD could be causing delays on this route. Construction works along the main alternate airport access route from the CBD Kingsford Smith Drive may have also slowed travel times. The CBD Chermside Corridor also experienced greater variability in peak travel time on both inward and outward bound trips, compared to off-peak travel, as shown in Figures 16 and 17.

Perth Completed infrastructure upgrades provide a bright spot for Perth Figure 18 below shows Perth s relatively low levels of travel delay across its zones and corridors, which is in part due to subdued economic activity. While there was a modest deterioration in the headline Travel Time Index reading, Perth s CBD Airport Corridor was the best performing route out of the four cities, since the Australian Travel Time Metric commenced in 2.

Analysis Perth sees comparatively low levels of delay on key routes compared to other cities, which is in part due to realising the benefits of infrastructure upgrades, but also due to subdued economic activity. Perth saw gradual and consistent improvement to journey times on the CBD Airport route, as seen in Figures 19 and 2, which coincides with the progressive completion of the Gateway WA project. Notably, the shortest total delay across all cities and routes was the commute from the CBD to the Airport, which experienced a mere 1.3 minute delay. Further, travel time on this journey was only six per cent longer during peak hours the lowest percentage change on any route across all cities over Q2 217. This journey also showed the lowest variability for peak and off-peak travel times across all routes and cities, resulting in minimal variability in travel delay less than a minute in Q1 217. Meanwhile, the CBD Fremantle peak travel delay was the worst performing journey for Perth in Q2 217 with a 7.8 minute delay the second highest recorded on this route since the Australian Travel Time Metric commenced (see Figure 22). The inbound trip on this route also saw greatest variability for Perth, across the reporting period, with average delays fluctuating between 8.9 and 4.8 minutes. Inner Metro and travel delays have remained relatively consistent for commuters at around 3. 3. minutes since the Australian Travel Time Metric began. Meanwhile, Outer Metro delays have increased since Q3 2, while travel delay has decreased. Australian Travel Time Metric 217 Edition 19

Context why use the data? Historically, transport policy has focused on measuring inputs, like the amount of money invested in new road and rail capacity, or relatively crude estimates of assumed project benefits versus costs, which are rarely (if ever) verified. But the rapid development of technologies across the transport network is generating a wealth of raw data; offering a largely-as-yet-unrealised opportunity to gain a much more sophisticated understanding of how Australia s transport systems are performing. Last year IPA and Uber released the IPA Australian Travel Time Metric, Australia s first standardised measurement of road network performance across Australia s four largest cities: Sydney, Melbourne, Brisbane and Perth. This booklet provides the 217 edition of the Australian Travel Time Metric, comprising updated travel time data from Q3 2 to Q2 217. The IPA Australian Travel Time Metric captures anonymised data from Uber trips through Uber s Movement platform, which provides road network travel time data for 28 cities across the world. Each trip is a mobile collection point for key traffic metrics such as travel times. This use of on-vehicle measurement systems will provide a wider, more detailed and granular picture of how the use of our cities transport systems evolves over time. Used well, Uber s underlying anonymised data and that of other transport operators provides new opportunities to better target infrastructure investment, assess the actual benefits of individual projects, and to understand how Australia is tracking in developing better cities and solving its mobility challenges. 22 Australian Travel Time Metric 217 Edition
Data ask the right question The IPA Australian Travel Time Metric uses the peak and off-peak travel time averages across select routes and the inner and outer metro regions to develop the Travel Time Index and Delays on Key Routes metrics. Given the seasonal and individual fluctuations in traffic, the Australian Travel Time Metric provides both a snapshot of travel time each quarter, but more importantly a long-term index showing travel time delay.

Part of these improvements has seen the definition of time periods expanded to allow for more reliable data. This has resulted in current and historical data being updated for the metric across all quarters. Australian Travel Time Metric 217 Edition 23
