View AllThe initial statewide driver traffic safety survey provides baseline metrics for the TSO and others in understanding perceptions and behaviors related to focus issues. A core set of questions addresses nationally agreed upon priorities, including seat belts, drinking and driving, and speeding. In addition... Depending on the location, highway bridges can often support considerable amounts of traffic. Due to the limitations on current earthquake forecasting techniques, a normal amount of traffic will also typically remain on a bridge when an earthquake occurs. In addition to traffic, scour effects are also... Commercial motor vehicle (CMV) enforcement efforts seek to make travel on public highways safer. CMV enforcement professionals secure compliance of CMV's with state laws regulating weight of commercial vehicles to protect state highways from unnecessary damage, and ensure payment of necessary registration... Bus Rapid Transit (BRT) is becoming one of the most popular transit services in the United States. BRT is a viable option for many cities and can offer commuters travel times comparable to those experienced in private cars. With about 100 miles of BRT service scheduled for deployment in future years... In this study, the current SDDOT Road User Cost methodology and associated unit costs were evaluated and changes were implemented to the methodology to allow for a more complete analysis that aligns with the needs of each department and their use of RUC. The methodology was used to construct a worksheet... The intent of the Rural Transit Fact Book is to serve as a national resource for statistics and information on rural transit in America. This publication includes rural demographic and travel behavior data as well as financial and operating statistics for agencies receiving section 5311 funding. In addition... The objective of this project was to evaluate the technical, operational, and economic feasibility of using medium-range radio frequency identification (RFID) technology to track transit passengers. The stages of the Effortless Passenger Identification System (EPIS) project consisted of four main tasks... Over the years, Fiber Reinforced Polymer (FRP) composites have gained popularity in transportation infrastructure as a material able to restore and increase the capacity of existing concrete elements. Properties such as a high strength to weight ratio, non-corrosive nature, durability, and high malleability... The purpose of this study is to provide information about railroad fuel efficiency that may be useful in evaluating transportation energy policies and assessing the sustainability of potential projects. The specific objectives are to (1) develop railroad energy efficiency models that describe differences... This report describes research performed in coordination with work at the University of Stuttgart, attempting to establish the S-N curve for fatigue loading of notched wood-concrete connections based on low/high-cycle, repeated loading tests. Experimental results are obtained on fourteen 1524 mm span... |
