Filter by Keyword217 report(s) found with age in the keywords field The National Transit Institute (NTI) contracted with the Small Urban and Rural Transit Center located within the Upper Great Plains Transportation Institute at North Dakota State University to complete a survey to assess the immediate training needs of rural and small urban transit agencies. The immediate... Achieving and maintaining public transportation rolling stocks in a state of good repair is very crucial to providing safe and reliable services to riders. Transit agencies that seek federal grants must also keep their transit assets in a state of good repair. Therefore, transit agencies in small urban... This study was conducted to provide the Oklahoma Transit Association and state policy makers with information that will allow them to plan for mobility challenges and address coming greater mobility needs stemming from population growth and changes in the state’s demographics. In this study, we constructed... The rise of ride-sourcing services such as Uber and Lyft in recent years has revolutionized urban transportation across the globe. With the increased popularity of these services came negative impacts on industries such as taxi cab and public transit services. In an era when ride-sourcing companies are... Moisture-induced damage (stripping) is a major distress in asphalt pavements. This study was undertaken to evaluate the effects of chemical Warm Mix Asphalt (WMA) additives, Reclaimed Asphalt Pavement (RAP), Anti-Stripping Agent (ASA), and hydrated lime on moisture-induced damage potential of asphalt... Construction of highways usually requires large areas of land disturbance, which may result in accelerated soil erosion. The stormwater runoff from highway construction sites typically contains a large amount of fine particles that are difficult to remove using conventional best management practices.... Intelligent transportation system (ITS) applications have been widely applied to the highway system, and are being used by an increasing number of small urban and rural transit systems throughout the United States. The objectives of this study were to first, identify what technologies are currently used... Calcium sulfoaluminate (CSA) cement was used to cast a prestressed voided deck slab bridge girder. The rapid-set properties of CSA cement allowed the initial concrete strength to reach the required 4300 psi needed in order to cut the prestressing strands 6.5 hours after casting. Prestress losses were... Bridge inspection data is an essential step in the bridge asset management operation and the bridge management system. As such, a reliability-based, holistic framework was proposed to effectively collect reliable data and perform data fusion and information fusion of sensory data used for element-level... Advances in electronics, wireless technologies, and mobile applications on smartphones have contributed to the tremendous growth of shared-use mobility (SUM) practices and Americans have embraced these new mobility options which are flexible, convenient, and affordable. Recognizing that technology enabled... |
