      <title>Scenario-Optimization-Based Velocity Planning of Autonomous Vehicles for Interacting With Pedestrians</title>
      <link>https://trid.trb.org/View/2553371</link>
      <description><![CDATA[This paper presents a velocity planning method for autonomous vehicles (AVs) to guarantee safe interactions with pedestrians at unsignalized crosswalks and with surrounding vehicles on the AV’s route. The method is structured within a hierarchical framework that includes robust control, a learning-based component, and a supervisory element. The learning-based component is trained using reinforcement learning techniques to reduce traveling time, minimize control interventions, and set the priority ratio between the AV and pedestrians. The supervisory element employs scenario optimization, using statistical data on pedestrian motions to ensure collision avoidance. A complex game-theory-based pedestrian model is formulated and analyzed in order to evaluate the effectiveness of the proposed velocity planning method. Extensive simulations are performed using the high-precision traffic simulator software SUMO. These simulations evaluate various aspects of the velocity planner, including computation time, traveling time, control interventions, and parameter settings. The results demonstrate the method’s ability to achieve real-time implementation while maintaining safety and performance objectives.]]></description>

      <title>Evaluation and implementation of shared spaces in NSW: stage 2a: empirical analysis of shared road infrastructure in NSW: collation of shared road infrastructure perspectives and local examples: final report</title>
      <link>https://trid.trb.org/View/2452430</link>
      <description><![CDATA[The iMOVE project ‘Collation of shared spaces infrastructure in NSW’, with Transport for NSW (TfNSW) and the University of Technology Sydney built on earlier work conducted by TfNSW to establish a common vision towards the design and implementation of shared spaces, and to identify existing local examples for further examination that can enhance future designs. Historically, road infrastructure and design have prioritised vehicle usage with the detrimental outcome being an increase in both vehicle dependence and traffic congestion. The last two decades, however, have seen a shift away from this vehicle-centric design towards more ‘shared space’ solutions. Shared space solutions seek to democratise road and street space by looking at ways to reduce the dominance of private vehicle use, encourage more active modes of transport and allow greater usage of urban space by people and communities.]]></description>

      <title>Innovation and Safe System Road Infrastructure</title>
      <link>https://trid.trb.org/View/1503496</link>
      <description><![CDATA[Implementation of Safe System in Australia and New Zealand demands many changes in the way road infrastructure is designed and delivered. While there have been many innovative road safety treatments successfully trialled and evaluated, their introduction into mainstream road planning and design has been very slow. This paper draws on innovation management and agile product development techniques to propose a streamlined innovation pathway to fast-track development, trialling and adoption of new Safe System road infrastructure solutions.]]></description>

      <title>Effects of land transport activities on New Zealand’s endemic bat populations: reviews of ecological and regulatory literature</title>
      <link>https://trid.trb.org/View/1486372</link>
      <description><![CDATA[Roading projects may have adverse effects on indigenous wildlife. In New Zealand the effects of roading on long-tailed bats (Chalinolobus tuberculatus) is an issue and projects have attempted to monitor and mitigate effects on bats populations. However, how to undertake monitoring and mitigation is unclear. The New Zealand Transport Agency commissioned Wildland Consultants, Landcare Research and AECOM to: review the literature on effects and mitigation of roads on bats, and relevant statutory processes; research road effects on long tailed bats; and develop a framework for managing these effects. Roads affect bats by severing their flight paths and depleting roosting habitat by removing trees. Most bat road research has quantified effects on behaviour rather than population survival, making prediction of effects difficult. No studies have demonstrated any mitigation options to be effective for bats. Demographic modelling indicated adult female survival is vital for the survival of long-tailed bat populations, and therefore must be preserved by roading mitigation. Research showed that nightly bat emergence is related to temperature, indicating that bat monitoring should be undertaken when temperatures 1–4 hours after sunset are above 5ºC, and preferably in the 10–17ºC range. Field research also showed a negative relationship between bat activity and night-time traffic volume. A framework guiding roading projects through the process of consents, ecological monitoring, and mitigation was developed and addresses ecological uncertainty around mitigation options, and describes improved bat monitoring.]]></description>

      <title>Fundamental objectives of road design</title>
      <link>https://trid.trb.org/View/1485227</link>
      <description><![CDATA[This report identifies improvements to guidance, education and practice to ensure the fundamental objectives of road design are achieved in new and existing road projects. The report provides a foundational road design definition and a series of road design principles that it recommends be incorporated into the Austroads Guide to Road Design. While the project concluded that the design guidance in Australia is technically sound, it recommended: 1. better educating designers and practitioners on the importance of road design objectives and how to achieve them; 2. improving design development and evaluation guidance to enable designers to apply robust engineering judgment, value engineering, Safe System principles, and assess whole-of-life costs; 3. providing evaluation tools to encourage the development and evaluation of multiple design solutions; 4. adapting existing design practices including requiring practitioners to demonstrate how design solutions achieve the objectives of road design.]]></description>

      <title>Consideration of life cycle energy use and greenhouse gas emissions for improved road infrastructure planning</title>
      <link>https://trid.trb.org/View/1459968</link>
      <description><![CDATA[The aim of my research was to contribute to improved road infrastructure planning by developing methods and models to include a life cycle perspective. In order to reach the aim, GHG emissions and energy use at different life cycle stages of road infrastructure were assessed in three case studies using Life Cycle Assessment (LCA). These case studies were also used for development of methodology for LCA of road infrastructure. I have also investigated the coupling of LCA with Geographic Information Systems (GIS) and the possibility to integrate LCA into Environmental Impact Assessment (EIA) and Strategic Environmental Assessment (SEA). The results of the first case study indicated that operation of the tunnel (mainly, lighting and ventilation) has the largest contribution in terms of energy use and GHG emissions throughout its life cycle. The second case study identified the main hotspots and compared two methods for asphalt recycling and asphalt reuse. The results of the third case study indicated that due to the dominant contribution of traffic to the total impact of the road transport system, the difference in road length plays a major role in choice of road alternatives during early planning of road infrastructure. However, infrastructure should not be neglected, especially in the case of similar lengths of road alternatives, for roads with low volumes of traffic or when they include bridges or tunnels. This thesis contributed in terms of foreground and background data collection for further LCA studies of road infrastructure. Preliminary Bill of Quantities (BOQ) was identified and used as a source for site-specific data collection. A new approach was developed and tested for using geological data in a GIS environment as a data source on earthworks for LCA. Moreover, this thesis demonstrated three possible ways for integrating LCA in early stages of road infrastructure planning.]]></description>

      <title>A review of project evaluation methodologies to address net impacts and risks of toll road projects to the community</title>
      <link>https://trid.trb.org/View/1457863</link>
      <description><![CDATA[Project evaluation is a process of measuring costs, benefits, risks and uncertainties for the purpose of decision-making by estimating and assessing impacts of the project to the community. The effects of impacts of toll roads can differ from those of non-tolled roads. Project evaluation methodologies are extensively studied and applied to various transport infrastructure projects. However, there is no definitive methodology to evaluate toll roads. This review discusses the impacts of toll roads then reviews the limitations of existing project evaluation methodologies when evaluating toll road impacts. The review identifies gaps in knowledge of toll road evaluations. First, the treatment of toll in project evaluation, particularly in Cost-Benefit Analysis requires further scrutiny to explore the appropriate methodology. Second, the project evaluation methodology needs to place strong emphasis on empirically based risk and uncertainty assessment. Addressing the limitations of the existing project evaluation methodologies will lead to an improvement in the methodology at a practical level and will fill the gap in knowledge of project evaluation for toll roads with respect to net impacts to the community.]]></description>

      <title>Integration of mega projects into the existing network: the critical role of traffic modelling</title>
      <link>https://trid.trb.org/View/1426994</link>
      <description><![CDATA[The NSW Government is committed to achieving one of the most ambitious infrastructure delivery tasks of recent times. The NSW State Infrastructure Strategy prioritises the delivery of a number of major public transport and road infrastructure projects to tackle congestion and sustain productivity growth in major centres and regional communities of NSW. Roads and Maritime Services has a key role to ensure the success of these major transport projects including through expert planning and preparation for integration of these projects into the existing road network. This paper provides a high level overview of the technical analyses carried out by Roads and Maritime to inform planning for two major projects, the M4 Widening of WestConnex and the CBD and South East Light Rail, into the Sydney road network. The paper outlines transport modelling analyses carried out to assess the forecast performance of the adjacent road network with these major projects and the integration measures identified through this modelling analysis to enable their successful implementation.]]></description>

      <title>Easing Sydney’s congestion: developing a road network for tomorrow’s Sydney</title>
      <link>https://trid.trb.org/View/1426969</link>
      <description><![CDATA[NSW has continued to grow through the transition from the investment phase of the mining boom to a more diversified economy underpinned by finance and professional services and a significant pipeline of public infrastructure projects. Sydney is vital to the continuing growth and prosperity not only of the city but of the state and Australia. However, the city’s population growth has led to increasing traffic volumes and congestion not only during traditional peak travel periods but increasingly on weekends. Major projects including Westconnex and Northconnex are already being delivered to connect the city’s motorway network. This is only part of the solution. Roads and Maritime Services (Roads and Maritime) is overseeing a billion-dollar program to tackle congestion on the network – we are doing this through a number of avenues including infrastructure and technology improvements as well as long-term strategic planning. This approach will address the issues faced by road users every day across the Greater Sydney network both now and into the future. But the future will bring new challenges including: 1. Changing expectations from our customers who are often time-poor; 2. Sydney moving from being an extensively developed city to one with a central ‘global’ pocket of high population densities; 3. Rapidly changing technology; 4. Government funding constraints; 5. Rising costs.]]></description>

      <title>Sustainability in road projects: building the business case</title>
      <link>https://trid.trb.org/View/1396421</link>
      <description><![CDATA[Transport infrastructure is critical to well functioning communities across the globe. Roads are public assets that are provided for the common good of society. With long life spans, roads have significant impacts and benefits to local communities through the ability to shape land use and urbanisation, support economic and community development and generate consequences for local environments. In response to a series of international commitments to sustainable development, many infrastructure agencies adopt sustainability objectives at a corporate level and incorporate sustainability targets and indicators as part of corporate reporting processes. Road agencies are now incorporating sustainability considerations into the design, construction and operation phases of road projects using tools such as the Infrastructure Sustainability tool developed by the Infrastructure Sustainability Council of Australia (ISCA). However, the decisions made within the planning phase provide the greatest opportunity to optimise sustainable outcomes at a broader level, including impacts on pavement solutions. There is a need to develop guidelines for investment decision making that better align with corporate sustainability objectives stated by infrastructure providers. It is proposed that a more effective decision making process should involve the incorporation of sustainability goals from corporate planning documents into the decision making process; problem definition and option generation using investment management guidelines as evidenced by “best practice” investment management processes; comprehensive analysis of project options and impacts using a range of assessment tools; and greater involvement from the public to accurately reflect community values and local knowledge that may not be documented or understood by infrastructure providers.]]></description>
