      <title>Driving India's Growth: the Pivotal Role of Indian Academy of Highway Engineers in Capacity Building</title>
      <link>https://trid.trb.org/View/2601654</link>
      <description><![CDATA[The esteemed institution, Indian Academy of Highway Engineers (IAHE), previously recognized as the National Institute for Training of Highway Engineers (NITHE), was established in 1983 as a society with the prime objective of providing essential training to highway engineers. Initially for 19 years, the academy operated from Delhi until October 1, 2001, when it relocated to its own sprawling lush green campus in Noida. In 2011, the institute underwent a name change, transitioning from NITHE to IAHE. Over the remarkable journey spanning more than four decades, IAHE has broadened its scope successfully across various domains, including training, transport simulation, and road safety, among others. In the rapid development of road infrastructure especially National Highways to realize the vision of a 5 trillion economy, IAHE plays a critical role in capacity building for road/highway professionals. This is essential to ensure the safe, sustainable, and efficient development of the much-needed highways infrastructure. The objective of this paper is to present a case study outlining IAHE's extensive 40-year journey and the transformative steps taken to fulfill the imperative Capacity Building among road/highway professionals.]]></description>

      <title>Encouraging the Next Generation of Low-Volume Road Engineers</title>
      <link>https://trid.trb.org/View/2593748</link>
      <description><![CDATA[Despite the critical role that low-volume roads play in rural connectivity and economic development, careers in this field are often overlooked by newly graduated engineers. The Road Engineering Association of Asia and Australasia (REAAA) hosts an annual Young Presenter Competition, providing early career professionals (i.e., under 35) in the road industry the opportunity to present research and projects on topics related to low-volume roads, often with a focus on practical implementation. By continuing to promote low-volume road management as a viable and fulfilling career, road agencies and industry associations can attract the next generation of engineers to the field and help ensure a sustainable workforce.]]></description>

      <title>Peer Exchange for Improving Accuracy of the Engineer’s Estimate for Highway Improvement Projects</title>
      <link>https://trid.trb.org/View/2408347</link>
      <description><![CDATA[The Wisconsin Department of Transportation hosted a peer exchange in 2021 to discuss topics related to improving procedures for developing the engineer’s estimate. The goal was to improve accuracy of engineers’ estimates by providing a forum for the exchange of ideas, lessons learned, and opportunities for the development of state-to-state relationships for continued improvements. Before the peer exchange, invited State Highway Agencies (SHAs) were asked to fill out an online survey to obtain preliminary information about their estimating procedures and practices, organizational approach, measurements of estimating accuracy and bidding history. Representatives from 16 SHAs responded to the survey and representatives from 11 SHAs and the Federal Highway Agency participated in the peer exchange. This article presents the results of the survey and a summary of the discussions during the peer exchange so that other SHAs can learn from them. The peer exchange provided a summary of the state of practice of the SHAs in preparing the engineer’s estimate and identified the following list of most impactful factors for differences between the engineer’s estimate and bidding results: low bid competition, geographic location, outdated data used in historical bid-based estimating, shortage of skilled workers and time, and market volatility. Discussions during the peer exchange uncovered how individual SHAs are approaching and dealing with these factors and those results are presented in the article. Other SHAs will benefit from the summaries of other SHAs’ current practices and the action items Wisconsin Department of Transportation identified resulting from the peer exchange.]]></description>

      <title>Lessons Learned In Roadway Design: A Few Nuggets Of Knowledge</title>
      <link>https://trid.trb.org/View/1759351</link>
      <description><![CDATA[With senior roadway design staff approaching retirement and 50% of the workforce to be millennials by 2020 (1), there are many design experiences that should be passed on to the next generation of roadway engineers and designers. It is important that this knowledge transfer occurs so the next generation of engineers can learn to minimize the number of design challenges they may experience. If some of these challenges can be reduced or avoided, the engineers can focus on reaching a beneficial design with fewer difficulties. This paper examines lessons learned in roadway design from the perspective of a chief roadway engineer and includes understanding design criteria, horizontal geometrics, combined geometrics, coordination with other disciplines, maintenance of traffic (MOT), plan production, and designing roads for the future.]]></description>

      <title>Immersive Work Zone Inspection Training using Virtual Reality</title>
      <link>https://trid.trb.org/View/1742668</link>
      <description><![CDATA[Can virtual reality tools be used to train engineers that inspect work zones? In this paper, we share the findings of a research project that developed an interactive and immersive training platform using virtual reality to train state department of transportation (DOT) staff that inspect work zones for compliance. Virtual reality offers an immersive platform that closely replicates the actual experience of an inspector driving through a work zone, but in a safer, cheaper, and quicker way than field visits. The current training practice involves reviewing temporary traffic control procedures, and reports and pictures from previous inspections. The developed platform consists of a learning module and an immersive module. The learning module is founded on the historical knowledge gained by DOT staff from inspections dating back at least 5?years. This knowledge incorporated representative inspection reports from previous years from all DOT districts including photographs of deficiencies. The synthesized knowledge was converted into a concise easy-to-consume format for training. The immersive module places the trainee in a vehicle moving through a work zone, thus providing a realistic experience to the engineer before inspecting a real work zone. The research team developed and tested two immersive scenarios of a freeway work zone. The training platform was tested by 34 individuals that worked for the Missouri Department of Transportation. An overwhelming majority (97%) agreed that virtual reality offered a realistic and effective way to train inspectors.]]></description>

      <title>The Engineering Geologist and Transportation</title>
      <link>https://trid.trb.org/View/1480125</link>
      <description><![CDATA[Transportation engineering geologists are called on to perform various duties for a public agency or consulting firm. Traditionally, many of these groups were named “Soils and Geology” units and were staffed by personnel with an engineering geology background. The geotechnical branch of civil engineering gained strength during the 1970’s and now many of the groups are staffed by both engineering geologists and geotechnical engineers. The tasks and responsibilities between the two professions are sometimes blurred. The responsibilities of Engineering Geologists within the transportation industry vary as widely as the geology of the 50 States. Their principal responsibilities include exploration and classification of earth materials, geologic mapping, geomorphology, geologic hazard identification, groundwater, geologic processes, rock discontinuity characterization. Problems can arise when engineers with little or no background or education in geology perform these tasks. Many geotechnical engineers have never had a university level course in geology. Transportation engineering geologists should have a role in the planning or NEPA process, identification of geologic hazards, route selection, bridge foundations, subsurface characterization and location of materials, slopes, especially rock slopes. Highway engineering involves many aspects of geology. Applying the principals of geology should make for less risk during construction and better, longer lasting, trouble free highways. The tasks an engineering geologist performs in highway engineering should be better defined given the evolution of the practice.]]></description>

      <title>Influence of Climate Prediction Models on Pavement Performance</title>
      <link>https://trid.trb.org/View/1439363</link>
      <description><![CDATA[Over the past 100 years, there is a significant shift in global climate. The unexpected levels of variability in climate has an adverse impact on the pavement performance. The climate is one of the critical inputs for the design of pavements. Currently, designers use the historical weather patterns for developing pavements and predicting their performance. Various changing climate predicting models are available for highway engineers. However, the output from each model is significantly different, and designers should comprehend the variability in the models. Even though climate change is a global problem, the type and range of impacts are very geographical sensitive. Generalization of climate change impacts on all geographic locations even within a state is not appropriate. The primary focus of this study is to document the dissimilarity in climate predicting models and variation in climate change in different geographical locations of the same state. To address this objective, the authors used six climate prediction models from North American Regional Climate Change Assessment Program (NARCCAP) databases. A typical pavement performance for four Cities Dallas, Amarillo, Corpus Christi, and El Paso of Texas are evaluated using Pavement Mechanistic-Empirical (ME) Design software. Despite the difference in predicted climate values by six climate models, all models showed a definite change in the future climate. The pavement distresses increase with the future climate scenario compared to the historical weather data, and its variation is noticeably different for the four cities. Each city needs a unique modified design to endure changing climate.]]></description>

      <title>Occurrence of Bumps in Overlays</title>
      <link>https://trid.trb.org/View/1401771</link>
      <description><![CDATA[The development of small bumps in the surface of hot-mix asphalt overlays has been a problem for state and local highway agencies for many years. Sometimes these bumps are small and are not large enough to be felt by drivers. Under many conditions, however, they can be large enough to cause ride-related problems at normal operating speeds. Under this project, a survey was conducted of local and state engineers in Minnesota responsible for highway construction and maintenance to compile corrective actions that they have used to avoid these bumps and to mitigate their effects if they occur. Instrumentation sites were incorporated into this project to determine the magnitudes and profiles of temperature in the existing asphalt layer when a new layer of hot asphalt is placed on top of it. The instrumentation sites were also used to gain further information on the common practices of highway construction personnel in reducing the probability of bumps, and mitigation efforts if bumps occur. This report describes the survey, site visits, construction instrumentation, laboratory studies, and evaluation conducted by the project team. It also presents a draft booklet compiling the common practices for avoiding and mitigating bumps gathered throughout the project.]]></description>

      <title>Expert System to Control Construction Problems in Flexible Pavements</title>
      <link>https://trid.trb.org/View/1246136</link>
      <description><![CDATA[This article discusses how highway engineers face complicated problems that are influenced by various conditions during the construction of flexible highway pavements. Identifying these problems and recommending effective solutions demand considerable engineering expertise, which is difficult to obtain at all construction sites. The development of an expert system can effectively help engineers control and analyze such problems. In addition, an expert system can effectively archive the storage and distribution of expertise among pavement engineers. This article describes the development and evaluation of such an expert system. The first stage in the development of the proposed system was the elicitation of knowledge from written sources and from experts through literature reviews and interviews, respectively. The acquired knowledge was analyzed and classified and then represented in a form containing rules and the rules were subsequently coded as software. This article describes the development and evaluation of the Expert System for the Control of Construction Problems in Flexible Highway Pavements.]]></description>
