View AllThis study examines rural transit needs for Jaunt. The objective is to quantify the need for transit services in each of Jaunt's partner jurisdictions. Jaunt provides transit in the city of Charlottesville, Virginia, and the counties of Albemarle, Buckingham, Fluvanna, Greene, Louisa, and Nelson. Neighboring... Two-lane highways comprise a considerable percentage of the nation's roads. A critical component required in the design of two-lane highways is the passing sight distance (PSD). In cases where it is inadequate, no-passing zones are established. There are multiple techniques employed for measuring the... Polymer concrete (PC) has found increasing use in construction over the last few decades. One common use of this material is as an overlay material on bridges and highways. This use can be attributed to some advantages of this material such as its high bond strength with substrate concrete, short curing... Transportation asset management requires timely information collection to inform relevant maintenance practices. Traditional data collection methods often necessitate manual operation or the use of specialized equipment, e.g., light detection and ranging (LiDAR), which can be labor-intensive and costly... In several states, bridge deck delamination of reinforced concrete bridge decks built with partial depth precast concrete panels and cast-in-place concrete has been observed. The partial depth precast concrete panels are typically prestressed. Recently, one such failure was observed in Utah. There is... This comprehensive report synthesizes findings from three distinct yet interrelated studies, each exploring the developing role of drones in the condition monitoring of multimodal transportation assets. The first study, a systematic literature review (SLR) on railway inspection and monitoring (RIM)... U.S. residents across many regions continue to face episodes of poor air quality due in part to pollution and emissions from the transportation sector. Strategies to encourage travel behavior changes and reduced driving during such events may or may not be effective. To illuminate how area-wide air pollution... A numerical model simulating the seismic behavior of precast concrete columns confined with glass fiber reinforced polymer (GFRP) spirals and longitudinally reinforced with steel or a combination of steel and GFRP bars was developed using the Open System for Earthquake Engineering Simulation (OpenSees).... This report documents the effort to develop a practical relation between the cracking tolerance index and portions of the dynamic modulus curves of asphalt mixtures. A review of practices used to create asphalt mixtures' dynamic modulus master curves, based on NCHRP reports and other relevant literature... Public transportation plays a fundamental role in the livability of communities of all sizes. The Rural Transit Fact Book provides information on transit service availability and cost to help the transit industry in the United States provide efficient and effective service to meet rural community mobility... |
