The Next Generation Equipment Committee (NGEC) developed a standard for specifying the use of an Ethernet based digital train line (DTL) network to replace the COMM line for passenger trains. These specifications are PRIIA 305‐919 Digital Train Line Hardware and PRIIA 305‐920 Digital Train Line Software. The intent Is to eventually allow for the improvement of passenger train control. DTL spec ...

U.S. DOT’s Zero Emissions Transportation Initiative is looking to push the transportation sector greenhouse gas production to zero by 2050. This solicitation/topic addresses alternative energy sources for the light vehicle, motorcycle, and bicycle sector. With the continuing significant development in commercialization and availability of biofuels, the possibility exists to meet this goal, with ...

This project seeks to define the performance requirements for a wireless Digital Train Line (WiDTL) through definition of functionality and performance expected, and translating these into network equipment specifications and architecture that wireless network equipment manufacturers can build towards. The effort will include an in-depth review of wireless technology as it applies to sensitive and ...

Autorack cars transport one of the most valuable commodities – fully assembled Automobiles. Due to the longer and higher profile of an Autorack and the fact that heavy automobiles are loaded on to high deck levels, freight trucks with improved track-to-vehicle dynamics as well as higher speed capabilities are desired in anticipation of higher speed passenger service and shared corridors. Unique ...

The goal of this project is to develop, prototype, and experimentally validate a new Differential Global Navigation Satellite System (DGNSS) capable of providing sub-centimeter positioning accuracy for quasi-static scientific, survey, and structural health monitoring application. The main feature of the proposed DGNSS solution is that it leverages publically available GNSS reference data from exis ...

The objective of the proposed work is to determine whether Dioxide Materials' miniature C02 sensors have the potential to be adapted for autonomous measurement of ocean carbon. The existing sensors have many advantages for measurements of ocean carbon. They are much smaller and less costly than the existing sensors, work with much smaller gas samples, and use much less power. The sensors were d ...

The goal of this project is to develop, implement, and experimentally validate a new Differential Global Navigation Satellite System (DGNSS) capable of providing sub-centimeter positioning accuracy for quasi-static scientific, mapping, and survey applications. The main feature of the proposed DGNSS solution is that it leverages GNSS reference data from existing NOAA's Continuously Operational Ref ...

Migration of the vehicle fleet from the current, pneumatic-only, automatic air brake (AAB) system to ECP presents a significant challenge due to the systems’ inherent operational incompatibility. This project will investigate the feasibility of devices that can help to ease this transition by allowing ECP equipped cars to operate in a conventionally braked train, as well as devices to permit con ...

Computation of the radiative transfer model for a hyperspectral sounder with thousands of spectral channels is very time-consuming. Consequently, operational data assimilation systems can assimilate only a few hundred channels. The radiative transfer model is very suitable for GPU implementation to take advantage of GPU massively parallel computing capability, where radiances at various channels c ...

More than 52% of U.S. urban highway congestion is a direct result of highway incidents.  Federal and State transportation authorities are searching for quick, cost-effective and efficient highway incident detection and warning systems.  Several solutions have been proposed but none could satisfy requirements of transportation authorities.  Central Signal's research and development, ...
