The causes analysed include recurring congestion, incidents, roadworks, weather, special events and other events. This analysis process produces unique and accurate artefacts for policy and investment decision-making. Opportunities arising include the potential to identify and prioritize congestion management initiatives, evaluate effectiveness of current initiatives and benchmarking performance. The analysis included a 12-month period on state-controlled roads in the Brisbane Metropolitan area. Topics discussed include: • The data required for the analysis • The key concepts of excessive congestion and abnormal congestion and how they are calculated • Overview of method for learning what is ‘normal’ on each segment of the road at any time of day (focus of co-author’s paper titled ‘A new process for learning what is ‘normal’ on road networks’) • Identifying abnormal congestion ‘footprints’ in space and time from the data • Associating identifiable causes to abnormal congestion events • Assigning costs where multiple causes were identified in an abnormal congestion event • Calculation and presentation of results • Data quality observations and impact on results and other potential improvements and • Additional opportunities arising.

Mobile mapping technology may be employed to prevent drivers of over-dimensioned vehicles from accessing restricted areas. Different applications of mapping technology have been studied for their applicability to manage access conditions, with consideration to the case study of access to Galston Gorge in NSW.

The strategic goal of the C2C Interface is to unite the distributed, multi- vendor control systems to provide a consistent driving experience for road users between public roads and various privately operated motorways across NSW. This interface provides visibility of the incidents and traffic on the NSW motorway network to RMS. It allows RMS to control select ITS devices on the private motorways. Utilising modern, non-proprietary, industry standard Web Services defined by WSDLs, SOAP messages are passed over HTTPS with agreed standardised content based on Traffic Management Data Dictionary (TMDD). Based on SOA (Service Orientated Architecture) principles and alignment with standards (TMDD and NTCIP), the interface solution allows for effective deployment, maintenance and ongoing evolution. The C2C interface is comprised of 3 components: C2C Interface Hub/Gateway (Enterprise Service Bus), TMC’s C2C Integration Platform and Motorway’s OMCS C2C software. The first 2 deliverables are reused for new motorway connections or extended for additional functionality and services. This paper presents a “gateway” approach based on non-proprietary technology and industry standards.

This results in less-than-anticipated returns from a large infrastructure investment, in addition to potential negative feedback from the community. With the best of road agency (including their consultants) technical skills in planning, design and construction of freeways, how could this happen? Main Roads Western Australia (MRWA) developed a process for Operational Efficiency Audits to avoid or minimize the possibility of such unintended consequences. Operational Efficiency Audits have assisted in uncovering the underlying causes for potential sub-optimal operational performance of freeways, providing an opportunity to optimise planning, design, construction and operation of freeways. In addition to geometric considerations, the audits seek to review provision of ITS technologies and operational strategies to ensure efficient and effective operation as a Managed Freeway. If undertaken sufficiently early in the lifecycle of a project, they may help in saving potentially costly modifications or improvements later. This paper outlines the Operational Efficiency Audit process, along with some case studies of the application for the process on several projects.

However in recent years the importance of the variability or reliability in travel time has been recognized as an important factor which affects traveller’s decision making. Thus travel time reliability (TTR) is a significant contributor to the benefit calculation in a business case. This paper describes a framework and methodology developed by The Industrial Sciences Group for an Australian Road Authority to model and quantify the economic value of planned improvements in travel time reliability due to a proposed ITS Initiative. The framework is designed to be generally applied – so it can be used to inform any business case to implement ITS technologies on new or existing motorways or arterial networks. For example – quantifying the commercial value of an improvement in travel time reliability due to active flow controls such as ramp metering or variable speed limits (VSL) The framework was developed after conducting a detailed review of overseas experience on how to robustly incorporate travel time reliability in cost-benefit analyses, without requiring substantial effort on the part of modellers and transport economists

This project seeks to investigate the hypothesis that off-peak (or out of hours) deliveries in urban areas have potential to reduce congestion and assist freight and logistics operations. The objectives of this project are to provide comprehensive insight into: (1) what drives current supply chain operations and time of day freight movement in urban areas, (2) barriers to changing freight movement to off-peak hours (e.g. night time) and, (3) potential ways to overcome these barriers. The investigation occurred in 2014/15 and was conducted in three phases: (1) international literature review of initiatives promoting the movement of freight in off-peak periods, (2) examining different supply chains and their practices in Australia and New Zealand, and (3) identifying supply chains and organisations interested in participating in off-peak delivery trials. Discussions with more than 60 people across 40 organisations including local governments and private industry were held during the course of the project.

It directly and indirectly employs 230,000 Queensland and generates approximately $60 million a day in visitor expenditure across the State . Part of the Queensland Department of Transport and Main Roads’ (TMR) role is to provide guidance and direction to the tourism industry on the implementation of tourism signage across the State. This signage provides directional assistance as to how road users get to particular tourism attractions. This paper will examine a new on-line system that the Department implemented two years ago that allows for tourism organisations to apply for tourism signage. The paper will discuss: • how implementation of this signage was done before • what were the challenges that TMR had to overcome and how these were addressed • what solution was subsequently put in place and • what was the outcome of its implementation.

Collecting the right data, and combining with known driving conditions is necessary to adequately model risky driving behaviour. This technical paper explores the leveraging of SUNATM (Traffic Content) in conjunction with UBI data, to overcome this barrier.

For Australians to be able to access the benefits of C-ITS, some additional investment will be required by Australian governments. Queensland Transport and Main Roads (TMR) has developed a pre-deployment program for C-ITS and Connected and Automated Vehicle (CAV) technologies to bring these largely internationally developed technologies to Australian roads. A range of technologies will be trialled over a five-year period in a large-scale deployment environment in South East Queensland, with the focus primarily on safety applications. The intent of this paper is to provide an overview of the program and an update of the project status. In addition, the paper presents a cost-benefit analysis tool developed to assess the C-ITS opportunity and estimates a benefit cost ratio for Queensland to assist Australian governments.

A key feature of this work is the extent to which alcohol interlocks are becoming part of interconnected systems of intelligent technologies, that are changing the way drivers interface with vehicles, and the way policy decisions are made. This work, which has been driven by the need to improve the operation and integrity of alcohol interlocks and associated policy, will also demonstrate how governments can use intelligent technologies and existing ITS frameworks to adopt fresh, innovative regulatory and technology approaches which deliver public purpose outcomes.

VicTraffic is the official suite of real time traffic apps from VicRoads. The apps deliver content to the user in real time. The largest problem solved was how to present large amounts and varied types of data, in different formats from different systems, quickly to the user in a meaningful way without overwhelming both the user and app. This was solved by developing an innovative asynchronous grid-based loading system. A complex and huge volume of data is innovatively represented in a simple and intuitive interface. The result is highly scalable mobile apps and desktop site, which are extremely available for hundreds of thousands of users in times of emergency. Uptime is consistently 99.99%. The solution doesn’t fall over in times of emergency (for example, during bushfire season).

The Framework supports a suite of established and emerging regulatory, policy and reform initiatives that use telematics, including: monitoring heavy vehicles’ road access, speed and mass; recording of driver work and rest hours for fatigue management; providing real-time information for drivers; alcohol interlock and taximeter reforms; and Cooperative Intelligent Transport Systems (C-ITS). This paper gives an overview of the Framework, including the purpose that it serves; its key principles; the roles and responsibilities provided in its architecture; its national and international linkages; and provides a case study of its inaugural application, the Intelligent Access Program (IAP), a voluntary program that uses the Global Navigation Satellite System (GNSS) to monitor heavy vehicles' road use, giving transport operators flexible access to the Australian road network to suit their specific business and operational needs. In return, IAP provides road agencies with confidence that heavy vehicles are complying with the agreed road access conditions.

This work, which has been driven by the need to improve the experience of taxi customers, will also demonstrate how governments can use ITS to adopt fresh regulatory approaches which respond to the disruptive influences occurring in the taxi and hire car sector – and the emergence of ridesharing services. Following a program of engagement and consultation with technology providers within the ITS sector, a new-generation of ‘Fare Devices’ are set to be implemented in Victoria from 2017.

Long term incidents, such as floods, road maintenance or major traffic incidents can cause significant disruptions on the traffic flows in large metropolitan areas such as Melbourne. There is a need to comprehend how traffic will be impacted in a city during such an event. One main reason for this is to manage the flow of this traffic so that it does not obstruct with emergency protocols. Such modelling requires the capturing of fast-evolving and ever changing conditions, taking into account road closures, Twitter or Facebook information as well as other circumstances. One important characteristic in traffic flow modelling is the ability to describe traffic burstiness, i.e. vehicles tend to cluster together, thus creating traffic congestion. This paper provides some promising results in regards to traffic flow modelling using point processes framework. We are able to simulate traffic flow that mimics real life conditions, and also perform efficient inference thereof.

A number of lessons have been learned by the TMC as it transitions to the new operating model. The paper will identify the business outcomes to be delivered by an integrated TMC, and how the TMC will interact with the public, transport operators and emergency services.

Previous DDI studies often considered the improved operation of the intersection that resulted in significant improvements in traffic throughput, safety, footprint and construction cost. The motorway-arterial road interface is critical to the strategic success of Smart Motorways. In this paper we consider the implication of implementing a DDI to vehicle flow on the motorway mainline and entry ramps, and the operation of smart motorway technology such as co-ordinated ramp metering. In particular, we will investigate the impact of improved flows achievable through a DDI on the Smart Motorway network and detail any potential need for increased delineated storage through the intersection, how will this affect the operation of an already congested motorway and any need to change the parameters for ramp metering design.

To fully realise the benefits of global and local C-ITS, it is critical that the environment in which C-ITS enabled vehicles, infrastructure and after-market devices operate is one underpinned by rigorous security principles. A key step in achieving this is to make security a priority from the outset. This not only ensures privacy and safety outcomes, but reduces the difficulties, risks and costs associated with building security measures into a system once it is established. Drawing on the collaborative efforts and results of work performed by International Harmonisation Tasks Groups (jointly lead by representatives from the United States Department of Transport, the European Commission and Transport Certification Australia), this paper provides an overview of international work in this area, and outlines the principles and features of a secure C-ITS operational environment.

Although the benefits of Electronic Work Diaries (EWD) have been identified, and they have been recognised in regulations since 1999, what would constitute an EWD, how much it would cost, how it would be used and the implications of collecting driver data, have been unclear. Following an Operational Pilot in 2011, the development of an EWD Functional and Technical Specification, and amendments to national laws in 2015, work is underway to implement EWDs as a voluntary alternative to written work diaries that are type-approved, and available through certified service providers. This paper provides a technical and operational overview of EWDs, their benefits, and focuses on the work currently being performed on implementing the EWD project.

An empirical model is developed for the greenhouse gas emissions based on multivariate linear regression to identify the main drivers of greenhouse gas emission. It has been found that the Vehicle-kilometers by Mode (VKM) and Number of Transportation Vehicle (NTV) are the most important variables that affect the gas emission. The results show that the multivariate linear regression model can be used to adequately model with coefficient of determination (R2) and adjusted R2 values of 85.1% and 83.2%, respectively.

Current VSL technology acting alone cannot prevent flow breakdown if demand is greater than capacity. Therefore, VicRoads’ approach to optimising freeway travel speeds, reliability and throughput is focused on managing the mainline with coordinated ramp signals (CRS). Simulation investigations have shown that VSL acting cooperatively with CRS has potential for improving traffic safety and efficiency. The next logical step which VicRoads has initiated includes on-road trials to develop the technology. The Dynamic Variable Speed Limit trial involves software development and on-road deployment of a VSL algorithm. Initially, this will enable variable speed limits to be automatically determined and adjusted by STREAMS in response to real time traffic conditions. The project will then move towards full integration of the software to optimise freeway operations with CRS.

The program is called the Interim OBM Solution as it is the first stage application of OBM for regulatory use. By enrolling in the Interim OBM Solution, vehicles can receive improved access arrangements, carry additional mass or operate with trailer combinations that might otherwise not be granted access to the road networks operators require. Certain vehicle types and combinations have restricted access to the road network due to, among other concerns, road and bridge asset protection. The access conditions of heavy vehicles are usually determined in a permit, gazettal or notice, issued by a Road Manager. The mass and location of enrolled vehicles are monitored for instances of non-compliance with the permit, providing Road Managers with confidence that the conditions of the permit are being met. For Transport Operators, better access in exchange for monitoring offers productivity and efficiency outcomes – greater loads, fewer trips, and more direct routes.

Almost 60 heavy vehicles and a range of roadside infrastructure have been fitted with CITS. Participating drivers receive visual and auditory messages on an in-vehicle display. Messages include collision avoidance warning between equipped vehicles and alerts when exceeding the heavy vehicle speed limit or approaching red traffic signals. This paper will discuss some of the lessons learned in the establishment of the testbed in relation to participant management and the design of the human machine interface.

Underutilisation of motorways can contribute to congestion, thus increasing the potential for incidents leading to delays and potential for serious injury, which in turn negatively impact community liveability. To meet this challenge, the Department of Transport and Main Roads (DTMR) have developed a suite of Managed Motorways (MM) Variable Speed Limit (VSL) algorithms to improve congestion and safety, thereby increasing liveability. The suite developed on TMR’s ITS platform includes; Queue Detection (QD), Queue Protection (QP), High Flow (HF) and Weather algorithms. This paper will discuss the algorithms; outlining their development, implementation, testing and performance. The QD/QP algorithm uses real-time detector data to recognise slow moving queues, dynamically generating responses on VSL Signs and Variable Message Signs (VMS) to reduce the potential for conflict. QD/QP is currently operating in a production environment, with it achieving the recommended targets for Key Performance Indicators (KPI) such as false alarm rate (0.4%), mean time to detect (152 seconds) and detection rate (100%). HF and Weather algorithms have been tested in a production environment during which they displayed promising and expected behaviour.

Therefore, VicRoads is increasingly becoming reliant on ITS assets in managing the operational performance of the road networks. Whilst Austroads are preparing a national roadmap, VicRoads as a road authority identify the need to develop an ITS Roadmap to allow the organization to forward planning and ultimately prepare for the deployment of available and upcoming technologies. This paper will discuss the approach that VicRoads has undertaken to develop the ITS Roadmap and present action plan that VicRoads will utilise to prepare for the deployment of upcoming technologies to maximise the use and benefits of ITS assets and systems and achieve the desired outcomes.

Queensland EVP technology is an intuitive and dynamic Intelligent Transport System (ITS) solution that automatically interrupts normal traffic signal operations to provide a green traffic light signal to emergency response vehicles (ERV), in advance of their arrival at an intersection, when safe to do so. This helps reduce ERV travel times while enhancing the safety of front-line officers, other road users and the broader community. Qld EVP uses a system to system approach rather than the Vehicle to Infrastructure approach that most other EVP systems use. This allows the full power of the STREAMS system to be used to manage the interventions to ensure safe and efficient EVP operation while minimising the impact of the intervention on normal traffic operations.

This approach is new to New Zealand, and takes a globally innovative approach within the context of the method of triggering VMSL regimes. The presentation will share the lessons learned during the development of the process and the uses of the relevant technology. The VMSL regime will be controlled and implemented through a Model Predictive Control framework approach, creating a predictive model which will sit inside NZTA's SSDF system. The model will use a VMSL algorithm, which will trigger the Dynac operating system to set a VMSL regime, depending on the current and predicted traffic conditions. The presentation will describe how the use of technology and data has been planned and implemented from advanced traffic detection, database incorporation, through integration with multiple operating systems and then communicated to the customer and monitored for performance. The project has assembled a unique blend of software and systems engineering, GIS, ITS and traffic modelling expertise to deliver this for NZTA and the approach and methodology of the integration of these components will be described in detail.

Road agencies which are tasked with ensuring that freight standards are maintained for safety and road asset maintenance reasons are faced with the complex task of maintaining compliance. As freight volumes grow the percentage of heavy vehicles that are able to be inspected reduces. Therefore there is a need for targeted enforcement. As road agencies have limited resources to undertake inspections and to also encourage compliance, and to reward those heavy vehicles complying with the rules, road agencies are seeking out technology solutions to automatically detect those vehicles suspected of having a non-compliance and to bring them in for manual inspections. This paper discusses some of the current and emerging technologies used by road agencies to screen heavy vehicles and to identify vehicles requiring manual heavy vehicle compliance checks.

Given the rapid advances in sensor and display technologies, combined with their cheaper costs, there is a wide range of potential improvements that could be made. The purpose of this work was to better understand commercial operators’ information needs in order to prioritise potential improvements. This paper covers the key findings of this research and provides recommendations for future actions including: improvements to data quality, development and implementation of consistent standards and operating procedures, and the need for ongoing monitoring.

As both Aurizon and Queensland Rail both use the same Train Control Systems, Universal Train Control (UTC) and Direct Traffic Control (DTC) a joint initiative was established to implement a Track Access System (TAS). The TAS has the key objectives to improve the efficiency by providing a means for Track Workers to view rail traffic and request rail corridor access; to improve the ability of Track Workers to determine their location on the rail corridor through the use of GPS to identify the worksite location; to reduce the number of safety breaches relating to track authority requested and given on the rail networks by improving the location assurance of workers and the protection applied; and to reduce the number of incidents by providing an efficient method of electronic track access. This paper will present the results, key lessons learnt and recommendations from the TAS implementation (completed), the operational field trial (current) and the eventual rollout into operations (to be completed).

Unlike humans, ant colonies have been shaped by millions of years of natural selection and may therefore have evolved solutions to many of the problems faced by today’s intelligent transportation systems. I propose that intelligent transportation systems are increasingly decentralised, interdependent, autonomous and cooperative – indeed, they are becoming more like ant transportation systems. The convergence of human and ant transportation systems creates exciting possibilities for collaborative research between ITS professionals and insect scientists. In this paper I provide a brief overview of ant transportation systems and highlight areas where collaboration between insect scientists and ITS professionals may yield useful results. I focus on two key problems: building resilient, dynamic networks, and cooperative management of traffic flows. I suggest that ants, of which there are ~12 000 species, represent a potentially vast toolbox of novel and useful solutions that can provide inspiration for ITS professionals.

It was desired to review these projects to establish the extent of realised benefits. A methodology and tool to assess the impacts and effectiveness of pinch point projects was developed. The methodology utilised a combination of traffic count data from SCATS loop detectors and travel speed data from vehicle probes equipped with location devices. The method and tool was applied to assess a weekend clearway scheme on Victoria Rd (Sydney). The method and tool resulted in a good understanding of the operational impacts of the pinch point project.

The typical fibres backbone cable route used by DAS can have significant offset distance from the road carriageway at many locations due to infrastructure and environmental limitations this in return has a direct impact on the DAS capability to detect and measure vehicle movements. This paper discusses how New Zealand Transport Agency (NZTA) uses micro-trenching technologies to improve its existing fibre backbone cable route, and summaries the enhanced of DAS application for congestion and incident management as a result of enhanced fibre deployment
