The DOT Regions - Maritime Administration (MARAD) Gateways 2023-Present dataset is from the U.S. Maritime Administration (MARAD), and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics’ (BTS's) National Transportation Atlas Database (NTAD). This dataset depicts the geographical boundaries of MARAD's nine Ga

The primary objective of this project was to compare ramp metering algorithms and develop guidelines for improving ramp metering operations in Texas. As part of this research project, researchers collected data at several sites in Houston, Texas. Data analysis showed that many congested freeways are facing heavy ramp demand and require significant

In an urban environment drivers typically have numerous information sources contributing to performance of driving tasks. An objective of this research is development of a practical tool to help traffic and safety professionals analyze driver information load and select countermeasures for information level corrections. The first task to accomplish

The Right-of-Way (R/W) acquisition process involves the coordination of various entities including multiple Texas Department of Transportation (TxDOT) districts, divisions, local, state, federal agencies, and private companies. Delays in the acquisition process necessary for the successful delivery of R/W for construction have historically caused p

Permanent stormwater quality structures in developed urban areas require the use of smaller footprints and underground structures. This project was undertaken to see if an underground treatment structure composed of off-the-shelf precast concrete sections would have adequate performance and require minimum maintenance. The project consisted of a li

To preserve the scenic value and attractiveness of state-maintained highways, Texas regulates the placement and dimensions of outdoor advertisements. The Texas Department of Transportation (TxDOT) administers and enforces these regulations except in certain cities that have been delegated to assume these responsibilities. The Department is interest

The network of US railroads often spans remote parts of the country that are sparsely populated. In these areas, rail grade crossings are much less likely to have warning lights or crossing gates primarily due to the lack of electricity. Such unprotected or passive crossings have the majority of the grade crossing fatalities and accidents. In order
...
Track intrusion, especially trespassing within railroad rights-of-way, poses a major safety risk, causing more fatalities than train-vehicle collisions. Existing methods often struggle with real-time detection on edge devices. This study introduces YOLO-RCNN, a novel model integrating YOLO-FG for comprehensive object detection and segmentation, opt
...
The expansion of urban railway networks improves mobility but simultaneously increasing unpredictability in traffic systems particularly due to significant delays experienced by first responders at level crossings blocked by passing trains. While existing routing systems may account for train-induced blockage durations, they often overlook the addi
...
Efficient railroad infrastructure monitoring and assessment is a critical issue for safe and sustainable operations. Apart from scheduled inspection and routine maintenance, there is a need for rapid assessment of the rail network after major events. For example, a storm can affect the traversability of a line (downed trees, rocks or flooding can b
...
Safety at grade crossings is a major concern due to the number of accidents every year. Many innovative technologies have been proposed to automate the monitoring of crossings. The goal of this research is to investigate the use of Artificial Intelligence (AI) and Deep Learning (DL) to monitor grade crossings and detect various hazardous conditions

This study investigates an electromagnetic energy harvester that utilizes an impact-driven frequency up-conversion mechanism to convert low-frequency vibrations into electrical power. The device consists of a plastic cantilever beam with a copper coil attached at its free end, oscillating between two stationary neodymium magnets. A stopper beneath

The wind-induced vibrations of the mast arm of cantilever traffic signal structures can lead to the fatigue failure of these structures. For this project, both full-scale and wind tunnel tests were conducted to study the behavior of the structures. Results of these experiments indicated that when the signals have backplates, vortex shedding can cau

Past research projects illustrated temperature differentials greater than 25°F on hot-mix asphalt (HMA) construction projects, indicating potential segregation problems in the mat. Through the years infrared cameras have been used to collect thermal data on newly placed HMA projects. Texas Transportation Institute (TTI) researchers refined infrared
